Forgetting is an adaptive process that can limit the interferences from irrelevant distractors and update valuable information. With regard to negative events, intentional forgetting can effectively help us to recover from trauma. The research on the intentional forgetting of emotional information usually adopts the directed forgetting paradigm. The better memory performance of R items relative to F items is referred to as the typically directed forgetting effect. Although emotional information is thought to be easier to remember than neutral information because of the attentional capture and elaborative process, whether emotional information is more resistant to forgetting is obscured. Most studies on emotional directed forgetting used various discrete items, such as words and pictures, and few addressed continuous events that are actually common in our episodic memory. Directed forgetting is not an all-or-nothing phenomenon because specific and general information appears to be forgotten at different rates. Therefore, this study aims to investigate the influence of emotions on the directed forgetting effect of continuous events. This study also explores the differences in forgetting rates between general/gist memory and specific memory.
In the present study, we adopted the event directed paradigm that embeds memory instructions into continuous videos. In experiment 1, 36 participants were equally divided into two groups: one group watched a neutral video, and the other group watched a negative one. Each video contained nine R segments and nine F segments that were surrounded by green and purple borders. The colored borders acted as memory instructions. The participants were asked to remember the video segments when the border was green and to forget the video segments when the border was purple. The test phase involved free recall and recognition. The participants were requested to recall all information about the video regardless of the classification of the memory instruction (R or F segments). Then, the participants were asked to identify the old pictures among the distractors. The old pictures were taken from the studied videos, and the distractors were slightly similar to the old pictures. The participants’ responses were classified as general/gist memory and specific memory on the basis of previous studies. In experiment 2, we disrupted the play order of segments to further explore the influence of continuity on the directed forgetting effect.
The results of experiment 1 showed that the directed forgetting effect was lower in the negative video than in the neutral video. In addition, the participants demonstrated good memory for the general/gist information of the negative video in free recall. In the recognition phase, no directed forgetting effect was observed for specific memory in the negative video. The result indicated that emotions impaired or eliminated directed forgetting for continuous events. However, the performance of the gist-only memory for the R and F segments was not significant in the neutral and negative videos. Therefore, we speculated that the sequential play of segments might have led to the possibility of participants correctly guessing the general gist of the content. Therefore, we disrupted the order of segments in experiment 2, and the results showed a typically directed forgetting effect for gist-only memory.
In conclusion, directed forgetting could appear in continuous events. However, emotions impair the directed forgetting effect for a specific memory. For gist-only memory, the directed forgetting effect is affected by the continuity of events.

Effects of lyrics on the processing of musical emotion: Behavioural and ERP study
ZHANG Weixia, WANG Wanqi, ZHOU Linshu, JIANG Cunmei
Acta Psychologica Sinica    2018, 50 (12): 1346-1355.   DOI: 10.3724/SP.J.1041.2018.01346
Abstract   HTML   PDF (1036KB)

Music and language are unique to the human beings. It has been suggested that music and language have a common origin as an emotional protolanguage. The development of socialisation has resulted in the development of language into a symbolic communication system with explicit semantics. By contrast, music has become an important means of emotional expression. However, whether language with explicit semantics affects the emotional processing of music remains uncertain. Given that songs contain melody and lyrics, previous behavioural studies have focused on songs to analyse the influence of lyrics on the processing of musical emotion. However, several studies have also shown the influence of lyrics, although such findings are relatively contradictory.

Thus, the current study used behavioural and electrophysiological measurements to investigate the impact of lyrics on the processing of musical emotion. Experiment 1 analysed whether the emotional connotations in music with and without lyrics could be perceived by listeners at the behavioural level. Experiment 2 further investigated whether there are different neural responses to emotions conveyed by melodies with and without lyrics.

A cross-modal affective priming paradigm was used in Experiments 1 and 2, in which musical excerpts served as the prime and emotional faces as target. To avoid the impact of familiarity, 120 musical stimuli were selected from European opera. Each was sung by a vocalist with and without lyrics, thereby resulting in 240 musical stimuli in two versions as potential prime stimuli. A total of 160 facial expressions affectively congruent or incongruent with the preceding musical stimuli were selected as potential target stimuli. Three pre-tests were conducted to ensure the validity of the stimuli. Eventually, 60 musical stimuli for each music version were selected as the prime stimuli, whilst 120 images were used as the target stimuli, thereby resulting in 240 music-image pairs. To ensure that each stimulus appears only once for each participant, two lists were prepared using a Latin square design. Each prime and target was presented in either the congruent or incongruent condition within each list. Thus, each list comprised 120 trials, with 30 trials in each condition. During the experiment, the two lists were equally distributed across the participants. A total of 40 healthy adults participated in Experiment 1. They were asked to judge as quickly and accurately as possible whether the emotion of the target was happy or sad. The accuracy and reaction time were collected. Meanwhile, 20 healthy adults participated in Experiment 2. They were required to judge whether the emotion between music and image was congruent or incongruent whilst their EEG waveforms were recorded. ERPs were analysed and compared between conditions at the time windows of 250~450 ms and 500~700 ms after the onset of the target.

The Experiment 1 results showed that when faces were primed by music either with or without lyrics, the participants responded faster and more accurately under affectively congruent condition compared with affectively incongruent condition. This finding indicated that the emotional connotations in music with and without lyrics could both be perceived. The ERP results in Experiment 2 showed that distinct neural mechanisms were activated by music with and without lyrics. Specifically, when faces were primed by music without lyrics, a larger N400 was elicited in response to affectively incongruent pairs than to affectively congruent pairs at the time window of 250~450 ms. However, when faces were primed by music with lyrics, a more positive LPC was observed in response to the affectively incongruent pairs than to the affectively congruent pairs at 500~700 ms. This finding confirms the results of Experiment 1, thereby suggesting that the emotion conveyed by music with and without lyrics could be perceived by the listeners. Moreover, the emotional processing between music with and without lyrics differs in the time course of neural processing. That is, the emotional processing of music with lyrics lagged behind that of music without lyrics.

In conclusion, the present results suggest that the neural processing of emotional connotations in music without lyrics preceded that of music with lyrics, although the emotional connotations conveyed by music with and without lyrics could both be perceived. These findings also supported theory of musical philosophy, which suggests that music without lyrics can express emotion more immediately and more directly than music with lyrics owing to the lack of “translation” from the propositional system. On the other hand, considering that lyrics influenced the time course of emotional processing in music with lyrics, our results also provide evidence that the emotional processing of music and language may share neural resources to some extent.

Mindfulness training can improve 3-and 4-year-old children’s attention and executive function
LI Quan,SONG Yanan,LIAN Bin,FENG Tingyong
Acta Psychologica Sinica    2019, 51 (3): 324-336.   DOI: 10.3724/SP.J.1041.2019.00324
Abstract   HTML   PDF (1319KB)

Mindfulness is a technique that alleviates the suffering of the yogi and implements self-awareness. Previous studies found that mindfulness training can improve work efficiency, emotional regulation, attention, and executive function. However, it is still unknown whether mindfulness training can improve attention and executive function in preschool children. This study sought to investigate the effect of mindfulness training for younger children to improve attention and executive function performance.
The present study attempted to use a 2 (group: mindfulness training vs no-training) × 2 (test time:pre vs post) between-and-within-subjects design to investigate the effect of mindfulness training on improving 3-and 4-year-old children’s attention and executive function. The mindfulness training consisted of 12 sessions, with 20~30 minutes per session, and was held twice a week for two months involving 6 preschoolers at a time. The children were assigned to two groups, mindfulness group (N = 26, age range from 41.69 months to 51.42 months, SD = 1.12 months) and control group (N = 26, age range from 41.98 months to 53.98 months, SD = 3.60 months). In the mindfulness training group, the instructor guided children to perform activities of mindfulness, while children in the No-training group were given normal activities. In the study, the mindfulness training course consisted of three parts. Part 1 was “breath and attention” that children learned to master belly breathing and focused attention on specific sensory. Part 2 was “body perception and movement” that children gained balance awareness and body coordinates. Part 3 was “awareness of mental activity” that children learned to relax and perceive each body part. Children’s attention was measured before and after training using an attention task (e.g. Finding Animals Test), and three components of executive function were measured before and after training using three classic tasks (e.g. Inhibition Control: Peach Flower Heart Task, Cognitive Flexibility: Dimensional Change Card Sort Task (DCCS) and Working Memory: WPPSI-VI’s Picture Memory Test).
To investigate whether mindfulness training can enhance children’s attention and executive function, we performed 2 (group: mindfulness training vs no-training) × 2 (test time: pretest vs posttest) repeated measures ANOVA. The results revealed that the interaction between group and test time was significant. An analysis of simple effects further indicated that in the pretest there was no significant effect between mindfulness training group and no-training group. In the posttest, the attention and two components of executive function performances (inhibition control and cognitive flexibility) improved significantly in mindfulness group, while no significant differences were found on attention and three components of executive function in no-training group. The results supported the usefulness of mindfulness training to enhance children’s performances on attention and executive function.
In conclusion, our results suggested the positive effects of mindfulness training on two components of executive function (inhibition control and cognitive flexibility) and attention in preschool children. The results provided important theoretical and practical implications for 3-and 4-year-old children’s attention and executive function.

Emotional regulation goals of young adults with depression inclination: An event-related potential study
LI Hong,YANG Xiaoguang,ZHENG Wenyu,WANG Chao
Acta Psychologica Sinica    2019, 51 (6): 637-647.   DOI: 10.3724/SP.J.1041.2019.00637
Abstract   HTML   PDF (2166KB)

Researches on deficits in emotion regulation of depression have mainly focused on the selection and application of emotion-regulation strategies; however, it remains unclear whether it is also related to emotion-regulation goals, i.e., the direction of emotion regulation. Situation selection is an antecedent-focused regulation strategy that is worked before the emotional reactions occur and it can be used as an index of emotional-regulation goals.

In our current study, the event-related potential (ERP) technique was used to investigate the emotion-regulation goals of young adults with depression inclination. Participants were asked to freely select the emotion-inducing scenes in which they want to put themselves and to report their emotional preferences。

ERP results revealed that the amplitudes of Late Positive Potential (LPP) were significantly decreased when viewing the sadness scene in young adults with depression inclination, and they selected to view sadness scene more frequently than healthy young adults. In addition, the ratings of sadness preferences were significantly higher among subjects with depression inclination, while the happiness preferences were lower.

The current results suggest that, compared to the control group, the individuals with depression inclination are more willing to use situation selection to maintain or enhance their sadness rather than weaken it or enhance their happiness. These findings further indicate that emotion regulation goals of depressive subjects may be related to their motivations for selecting emotional stimulus, and provide a new perspective for exploring the causes and mechanisms of emotion regulation deficits in depressive disorders.

The influence of facial trustworthiness on helping behavior: The role of attachment type
Xiujuan WANG,Na WANG,Shangfeng HAN,Shen LIU,Lin ZHANG
Acta Psychologica Sinica    2018, 50 (11): 1292-1302.   DOI: 10.3724/SP.J.1041.2018.01292
Abstract   HTML   PDF (785KB)

Researches on helping behaviors have always been a hot topic. Especially nowadays, helping others has become a risk-taking decision-making. Helping behavior is defined as an action that benefits others without return. In strange situations, the face, as the only clue to communicate or obtain information from, can affect people’s behaviors to a great extent. However, previous studies on helping behaviors did not take this issue into account, this study intended to combine situational factors and individual factors to comprehensively explore their impact on helping behaviors and to further investigate the moderating role of attachment security in the relationship between facial trustworthiness and helping behaviors.

This study included two experiments. Experiment 1 explored the effect of the characteristics of helpers’ trait attachment and facial trustworthiness by using a mixed experimental design of 2 (facial trustworthiness: high/low) × 3 (attachment type: security/anxiety/avoidance). Experiment 2 used a 2 (facial trustworthiness: high/low) × 2 (state-security attachment priming: yes/no) to investigate whether priming security attachment had safe influence as trait security attachment. During both experiments, subjects were presented randomly with faces of different facial trustworthiness. Participants selected their willingness to help others and donate money. The amount of money they donated represented their helping behaviors. These two indices were selected as dependent variables. A 7-point scale was used to measure help-willingness. The higher the score, the stronger of the willingness to help the seeker of participants. The amount of donation was between 0-100. The larger the number of donation, the more they were willing to contribute.

This study used SPSS 20.0 to analyze the data of the experiment, and the results verified the research hypotheses. The results of experiment 1 showed that there was a significant interaction between facial trustworthiness and the types of helpers’ attachment. The simple effect analysis showed that there were significant differences in the willingness and people’s behaviors with security attachments in both of the two facial trustworthiness, the willingness and money they input in high-facial trustworthiness were significantly higher than those in low-facial trustworthiness situation. There were also significant differences in the willingness and behaviors between low and high facial trustworthiness both anxious individuals and avoidance individuals. The willingness and behaviors to help in high-facial trustworthiness situation were significantly higher than those in low-facial trustworthiness situation. The results of experiment 2 on willingness and behaviors showed that there was a significant different in the interaction between facial trustworthiness and the types of helpers’ attachment. The simple effect analysis showed that there was a significant difference between the two facial trustworthiness situations for individuals of security attachment and a significant difference between the two facial trustworthiness situations for individuals of insecurity attachment, the willingness and helping behaviors in the high facial trustworthiness situation was higher significantly than low-facial trustworthiness situation. The different value in willingness and behavior in both experiment 1and experiment 2 under two facial trustworthiness situations for individuals of security attachment were significantly smaller than those for individuals of insecure attachment, indicating that attachment security to some extent had a regulatory role, it could buffer the risk-aided behavior to bring down.

This study has some significance. First of all, this study incorporated facial trustworthiness into helping behaviors, which provided a new way of researches of helping behaviors. Looking from the perspective of the face helped to distinguish the unfamiliar environment’s helping behaviors from the familiar environments. Second, the study found that individuals’ attachment types and the seeker’s face trustworthiness affects the helping behavior, indicating that the help-taking behaviors were the result of multiple factors, to remind the public to combine the help-seeking environment objectively and justly to see others’ behaviors. The media should also adopt a pragmatic attitude towards reports of people’s help behaviors so as to avoid reporting off the factual basis.

Differences in cognitive inhibition between persons with high and low creativity: Evidences from behavioral and physiological studies
Xuejun BAI,Haijuan YAO
Acta Psychologica Sinica    2018, 50 (11): 1197-1211.   DOI: 10.3724/SP.J.1041.2018.01197
Abstract   HTML   PDF (803KB)

Creativity has been previously defined as a behavior or product that is both novel and appropriately useful. It is a complex concept with many different processes, indicating that some of these processes require heavy executive processing. Executive function is the basic ability of cognitive processes to control one’s thoughts and behaviors, which is related to the prefrontal cortex, and it is mainly composed of three components: mental set transformation, inhibitory control, and working memory updating. Previous studies examining the relationship between cognitive inhibition and creative thinking have obtained inconsistent results. The following three hypotheses can be formulated regarding the relationship between cognitive inhibition and creative thinking. Creative thought has been variably associated with focused attention and effective inhibition control, disinhibition, and defocused attention or a flexible adaption of inhibition control.

The aim of present study was to investigate the relationship between cognitive inhibition and creative thinking using behavioral and physiological indexes, and the effects of time pressure on the relationship between cognitive inhibition and creative thinking. In this study, undergraduate students with different divergent thinking levels were asked to perform the Stroop task. In Experiment 1, a Stroop color naming task was carried out to test participants’ cognitive inhibitory ability. In Experiment 2, a more flexible Stroop word-color naming task was adopted and the physiological data was recorded to further investigate the relationship between cognitive inhibition and creative thinking, and time pressure situation was applied concerning reaction time. When participants responded after more than 550 ms, feedback of “too late” appeared on the display.

The results found that in Experiment 1, the highly creative persons showed smaller interference effect than did less creative persons; in Experiment 2, there was a significant time pressure condition × group × stimulus congruence interaction. The interference effect between the condition of time pressure and no time pressure of the highly creative persons was smaller than that of the less creative persons. Moreover, the time pressure condition × group interaction reached significance; the less creative persons showed significantly greater increases in skin conductance responses (SCRs) under the time pressure condition than in the no time pressure condition, but there was no significant difference for SCRs between the condition of time pressure and no time pressure of the highly creative persons. Furthermore, the highly creative persons exhibited significantly greater increases in SCRs under the incongruent condition in color naming task than in the congruent condition; however, they showed no significance between the congruent and incongruent conditions in the word naming task. There was no significant difference in SCRs between the congruent and incongruent in word and color naming tasks of the less creative persons.

The above results indicated that highly creative persons showed stronger cognitive inhibitory ability than did less creative persons; they could effectively suppress dominant but irrelevant response tendencies. Moreover, time pressure played a moderate role in the relationship between cognitive inhibition and creative thinking. Highly creative persons could focus on task-related information and inhibit task-unrelated information, adjust their attention to adapt to different time pressure task situations, and inhibit the interference characteristics. The highly creative persons showed variability in autonomic arousal levels in different conditions; the less creative were essentially fixed in a state of cognitive inhibition. The results agree with the hypothesis of adaptive cognitive inhibition of creative thinking.

The influence of shame on deceptive behavior: The role of self-control
FAN Wei,REN Mengmeng,XIAO Junze,JIAN Zengdan,DU Xiaoming,FU Xiaolan
Acta Psychologica Sinica    2019, 51 (9): 992-1006.   DOI: 10.3724/SP.J.1041.2019.00992
Abstract   HTML   PDF (1000KB)

Shame, as a typical moral emotion, has an influence on individual behavior that is both complex and controversial. Previous studies have found that shame produces both an unpleasant experience and a moral emotion that encourages individuals to produce positive behaviors. In recent years, Hooge’s research has proceeded from the perspective of motivation. He believes that, no matter how shame makes individuals perform, their motivation is to restore and protect the damaged self. Therefore, based on Hooge's theory, this research will examine this typical immoral behavior as an example to discuss the impact of shame upon it and its ways.

In this study, students from a university were randomly selected as participants, and the number of each experiment’s participants was arranged according to the experimental requirements. Questionnaires and behavioral experiments were used throughout the experiment, and the experimental procedures were completed in accordance with the regulations of each experiment. The requirements for each experiment were different and the procedures for conducting the experiment were different. The statistical methods of the study were also based on the requirements of each experiment.

Experiment 1 examines whether shame has an effect on deceptive behavior. Its results show that the number and tendency of deception in the shamed group were significantly lower than in the control group. To more fully explore the impact of shame on deceptive behavior in different contexts, Experiment 2 improved upon the deficiencies of Experiment 1 and divided shame situations into two types: moral anomie and lack of ability. It was found that the number of deceptions in the moral anomie shamed group was significantly lower than that in the control group, and the number of deceptions in the lack of ability shamed group was significantly higher than that in the control group. To examine the specific methods and mechanisms of shame in affecting deception, we propose that shamed individuals increase their self-control resources and, thus, reduce the theory of fraud. Experiment 3a examined the impact of shame on self-control resources and found that the self-control resources of the shamed group were significantly higher than those of the control group. Experiment 3b explored the specific mechanisms of shame affecting deceptive behavior. It was found that self-control resources played a complete mediating role in the process of shame in affecting deception.

In summary, these findings suggest that shame can deter deception under certain conditions. The condition is that shame is caused by moral disorder rather than lack of ability; the mechanism of shame in affecting behavior may be: Individuals who feel shame will restore and protect the damaged moral self by mobilizing more self-control resources to influence behavior.

The effects of capacity load and resolution load on visual selective attention during visual working memory
LI Shouxin, CHE Xiaowei, LI Yanjiao, WANG Li, CHEN Kaisheng
Acta Psychologica Sinica    2019, 51 (5): 527-542.   DOI: 10.3724/SP.J.1041.2019.00527
Abstract   HTML   PDF (905KB)

Selective attention plays an important role in processing relevant information and ignoring irrelevant distractors. The relationship between visual working memory (VWM) and visual selective attention has been extensively studied. VWM is a complex system consisting of not only visual maintenance functions, but also executive control functions. High load on visual maintenance functions drains the capacity for perception and prevents distractors from being perceived, while high load on executive control functions drains the capacity available for active control and results in increased processing of irrelevant distractors. There are two types of load in VWM: capacity load referring to the number of items to be stored, and resolution load emphasizing the precision of the stored representations. It has been found that these two types of load exert opposite effects on selective attention. However the mechanism underlying the effects of different types of VWM load on selective attention is still unclear. In the present study, four experiments were designed to investigate how different types of VWM load affect selective attention.
Thirty-six participants were enrolled in Experiment 1, 2 and 3, respectively, and 14 participants were enrolled in Experiment 4. Participants were asked to perform both a VWM task and a visual search task. In the VWM task, participants had to retain colors in VWM to perform a change detection task. There were three levels of VWM load: baseline load, high-capacity load and high-resolution load. In the baseline load condition, participants were required to retain two colors and the change between the memory colors and the probe colors was large. In the high-capacity load condition, participants had to retain four colors and the change between the memory colors and the probe colors was also large. In the high-resolution load condition, participants had to retain two colors and the change between the memory colors and the probe colors was small. In Experiment 1 and 2, the visual search task was a Flanker task that was presented either in the periphery or in the center of the memory array. The Flanker task was presented with the memory array simultaneously in Experiment 1 and sequentially in Experiment 2. In Experiment 3, the visual search task was a Navon task. It was presented after the memory array and only in the center of the memory array. In Experiment 4, a Flanker task was presented after the memory array and only in the center of the memory array. EEG data during the memory interval were recorded by a 64-channel amplifier using a standard 10-20 system.
The results showed that high-capacity load and high-resolution load reduced Flanker interference, compared with baseline load, when the VWM task and the Flanker task were presented simultaneously, regardless of whether the Flanker task was presented in the periphery or in the center of the memory array. High-capacity load and high-resolution load also reduced Flanker interference, compared with baseline load, when the VWM task and the Flanker task were presented sequentially and the Flanker task was presented in the periphery of the memory array. Compared with baseline load, high-capacity load increased Flanker interference and high-resolution load reduced Flanker interference when the VWM task and the Flanker task were presented sequentially and the Flanker task was presented in the center of the memory array. Under the high-capacity load condition, the Navon interference for attending to global level was larger than that for attending to local level; under the high-resolution load condition, the Navon interference for attending to global level was smaller than that for attending to local level. ERP results showed that relative to the baseline load condition, the high- capacity load condition elicited smaller N2, whereas the high-resolution load condition elicited larger N2.
In conclusion, when the Flanker task is presented during encoding stage of VWM, high-capacity load and high-resolution load reduce interference. When the Flanker task is presented in the periphery of the memory array during maintaining stage of VWM, high-capacity load and high-resolution load reduce interference. These findings support the load theory of selective attention. However, when the Flanker task is presented in the center of the memory array during the maintenance stage, high-capacity load and high-resolution load lead to opposite effects. High-resolution load reduce interference, while high-capacity load increase interference. The underlying mechanism is that the different patterns of neural activity associated with the two types of VWM load may result in different distribution of cognitive control resources to selective attention.

Are we truly irrational and almost impossible to educate? Analyzing the scientific evidence behind libertine paternalism
Gerd GIGERENZER, LUAN Shenghua, LIU Yongfang
Acta Psychologica Sinica    2019, 51 (4): 395-406.   DOI: 10.3724/SP.J.1041.2019.00395
Abstract   HTML   PDF (506KB)

Based on research in psychology, libertine paternalists argue that our mind is systematically flawed, which leads to many cognitive biases that are too deeply entrenched to eradicate through education. Thus, they suggest that authorities should take lead and nudge people into proper behaviors and good decisions. However, from the perspectives of ecological rationality, the outcomes of the so-called cognitive biases may not be bad, and in many instances, can be even better than those of the so-called rational reasoning as suggested by libertine paternalists. We analyze the evidence libertine paternalists use to justify nudging and find two major problems: (1) some of the supposed evidence is the product of researchers’ narrow interpretations of what qualify as human rationality and rational thinking; and (2) some libertine paternalists selectively reported scientific evidence, neglecting or sparsely reporting research that show findings contradictory to their belief. We conclude that there is lack of evidence to support the assertion that people are irrational and almost impossible to educate. To invest on education and make people risk savvy not only has been shown plausible and applicable, but also should be a more sustainable solution than nudging.

Why “no” implies “negative emotion”? Emotional representation in negation processing
GAO Zhihua,LU Zhongyi
Acta Psychologica Sinica    2019, 51 (2): 177-187.   DOI: 10.3724/SP.J.1041.2019.00177
Abstract   HTML   PDF (602KB)

Propositional theories propose that negation is an explicit abstract symbol, while the embodied theories believe that negation is represented by perceptual symbols. However, both sides lack direct evidence. In the present study, we develop another approach to discuss the issue -- emotional representation. Emotion is viewed as another form of basic experienced symbols and an important component of internal states to construe the representation of abstract concepts. Thus, can negation be represented by emotion?
In the two experiments, negative and affirmative phrases with a construction of “you/meiyou (a/no) + neutral two-syllable Chinese nominal words (e.g., 有/没有铁轨, a/no rail)” were developed as experimental materials to explore the emotional representation of negation processing. In experiment 1, we used the Affect Misattribution Procedure (AMP), in which affirmative and negative neutral phrases were adopted as primes presented for 200 ms after a 0 ms or 300 ms blank screen (SOA: 200 ms and 500 ms), and target ambiguous Russian words with 6~7 letters were presented for 100 ms and then were substituted by the masking pictures. The participants were asked to judge the pleasantness of the target Russian words. In experiment 2, we applied the classical affective procedure (Bona Fide Pipeline, BFP), in which the same primes and the same two SOAs in experiment 1 were adopted, but the targets were Chinese affective words from CAWS, and the target word in each trail was diminished until the participants made the judgment on the pleasantness of the target word. The dependent variable in both experiments was the unpleasant response rationale.
The results of experiment 1 demonstrated that negative neutral phrases led to more unpleasant responses to the ambiguous Russian words than affirmative phrases in the 200-ms and 500-ms SOA conditions. In experiment 2, negation phrases promoted participants’ responses to negative target words and misled responses to positive words more than affirmative phrases. In other words, negation primed more unpleasant responses regardless of the valence of the target words in both SOA conditions. Lastly, we compared the results of experiment 1 and experiment 2 and discovered that in both measure methods, negative neutral phrases induced more unpleasant responses than affirmative ones, which implied that negation had negative valence and was represented by negative emotion.
The results from the two experiments showed that negation was represented by emotional symbols. Because the prime materials adopted in the two experiments were neutral in valence, the different unpleasant response rationales reflected the different valence of the polarity (negation and affirmation), which differed from the explanation of the processing difficulties theories of negation. The stability of this negative bias across two durations meant that the emotional features of negation were not a temporal response but a property of negation. The negative priming effects of negation in the AMP and BFP, which had different demands on attentional resources, were similar. This implied that the negative valence of negation could be activated automatically with unintentional processing.

Memory encoding, retention and retrieval of disgusting and fearful faces
ZHANG Dandan,LIN Yiqin,LIU Yunzhe,LUO Yuejia,JIANG Donghong
Acta Psychologica Sinica    2019, 51 (1): 36-47.   DOI: 10.3724/SP.J.1041.2019.00036
Abstract   HTML   PDF (884KB)

Emotional memory enhancement effect has been verified in various memory studies using negative material. So far as we know, four studies demonstrated that disgusting stimuli are associated with a higher recognition accuracy in memory task, compared to fearful stimuli. However, the underlying neutral mechanism is still unclear. Since emotional arousal and valence are two important factors showing emotional memory enhancement effect, they should be counterbalanced between disgusting and fearful material when the latter two emotions are compared in memory.
The current study used event-related potential (ERP) to investigate different effect of disgust and fear on memory encoding, retention and retrieval. In particular, the following ERP components were examined: the P1, N170 and P3 both during memory encoding and retrieval, and the negative-going slow wave (NSW) during memory retention. A total of 60 healthy adults were recruited to participate a delayed recognition task, among whom ERP data were collected from 30 participants.
It is found that the recognition performance was better for disgusting faces than fearful faces. During memory encoding, fearful faces evoked larger P1 amplitudes while disgusting faces evoked smaller P1 amplitudes, both compared to neutral faces. Similar ERP pattern was found in N170, i.e., fearful faces evoked larger N170 while disgusting faces evoked smaller (but not significant) N170. In contrast, the P3 component during encoding showed largest amplitudes in disgusting condition. During memory retention, the NSW was the largest for disgusting faces, smaller for fearful faces, and the smallest for neutral faces. During memory retrieval, the P1 pattern was the same as during encoding period. However, the N170 showed comparable amplitudes for fearful and disgusting faces, while the N170 evoked by neutral faces was the smallest. More importantly, the P3 was larger in the disgusting condition than in the fearful condition. In addition to emotion effect, this study also found the effect of memory load. High memory load resulted in lower recognition accuracy, longer response time, smaller P3 (both during encoding and retrieval) and N170 (during encoding), as well as larger N170 (during retrieval) and NSW (during retention), as compared to low memory load. Furthermore, the emotion effect on recognition accuracy, the P1, N170 and P3 during encoding was enlarged at high memory load.
This study demonstrated that three mechanisms may contribute to the enhanced memory for disgusting than fearful stimuli. The first is that increased attention is allocated by top-down control system to elaborately evaluate disgusting stimuli at the stage of memory encoding (reflected by encoding P3). The second is that extra cognitive resources are employed for disgusting stimuli during memory rehearsal and retention (reflected by retention NSW). The third is that increased effort is made to retrieve the memory regarding disgust (reflected by retrieval P3). The current finding could help to further understand the cognitive mechanism underlying emotional memory enhancement effect.

Enjoy the present or wait for the future? Effects of individuals’ view of time on intertemporal choice
XU Lan,CHEN Quan,CUI Nan,LU Kaili
Acta Psychologica Sinica    2019, 51 (1): 96-105.   DOI: 10.3724/SP.J.1041.2019.00096
Abstract   HTML   PDF (663KB)

Intertemporal choice refers to decisions involving tradeoffs among costs and benefits at different time points. Most research on intertemporal choice has explored the influence of choice attributes. The existing literature has also discussed the relationship between individuals’ subjective time conception and their intertemporal choice, especially from the perspective of individuals’ characteristics and internal states. However, few research has investigated the same relationship from the perspective of the general view of time among individuals. Individuals’ view of time can be classified into two types, namely, linear and circular views of time. We posit that views of time relate to individuals’ perception of change in their surrounding environment. Such views may affect individuals’ time perception and hence their intertemporal decision making.
Three studies confirm our hypotheses. Hypothesis 1 states that people with a circular view of time, relative to those with a linear view of time, prefer the larger but later (LL) option in an intertemporal choice. Study 1 tested this main effect between the view of time and intertemporal decision making. The results of Study 1 confirmed Hypothesis 1. Hypothesis 2 states that participants with a linear view of time, relative to those with a circular view of time, perceive a longer time delay in the LL option in an intertemporal choice; thus, they prefer the smaller but sooner option. Hypothesis 2 also states that time perception of delay in the LL option mediates the effect of individuals’ view of time on intertemporal choice. Study 2 tested the mediating effect of time perception in intertemporal decision making. Sixty-four participants were randomly assigned to one group with a linear view of time and another group with a circular view of time. All participants were presented with the same task and asked to finish the corresponding computerized questionnaires. The results of Study 2 supported Hypotheses 1 and 2. The ANOVA results indicated that the participants with a linear view of time perceived a long time delay and thus preferred the SS option in intertemporal decision making. Bootstrap mediating analysis indicated that time perception of delay mediated the influence of the participants’ view of time on intertemporal choice.
Hypothesis 3 posits that the presence or absence of a time marker moderates the effect proposed in Hypothesis 1. Study 3 was performed to test Hypothesis 3. A total of 122 participants were randomly assigned to one of four groups in a two (view of time: linear versus circular) by two (time marker: with marker versus without marker) between-subject experimental design. The participants were then asked to finish the corresponding experimental task. The ANOVA result revealed that the interaction term between view of time and time marker was significant. In the absence of a time marker, view of time significantly influenced the participants’ time conception. Such effect diminished with the availability of specific time markers. These findings supported Hypothesis 3.
This research confirmed the differences between linear and circular views of time in the midst of an intertemporal choice. Results revealed that people with a circular view of time, relative to those with a linear view of time, prefer the LL option in an intertemporal choice. The effect of such preference is mediated by time conception and is significant when specific time markers are absent.

The influence of moral relativism and disgust on moral intuitive judgment
GENG Xiaowei,FANG Jinru,HAN Yanfang,LI Zhongquan,ZHAO Mi,YANG Ye
Acta Psychologica Sinica    2019, 51 (4): 517-526.   DOI: 10.3724/SP.J.1041.2019.00517
Abstract   HTML   PDF (794KB)

The social intuition model suggests that moral reasoning occurs after moral intuitive judgment. The question of how people make intuitive moral judgments, and whether the process is influenced by reasoning and emotion, remains to be answered. The purpose of this study is to explore the influence of moral relativism and disgust on moral intuitive judgment. According to the unimodel of human judgment, intuitive and deliberate judgments are based on similar rules. The hypotheses are as follows: moral relativism increases moral intuitive judgment (H1) and disgust increases moral intuitive judgment (H2).

We conducted three experiments to test these hypotheses. In Experiment 1, we examined whether moral intuitive judgment exists. A total of 39 undergraduates were selected and asked to answer “yes” or “no” randomly, like tossing a coin, to 20 moral behaviors, 20 immoral behaviors, and 40 fillers. The accuracy of moral judgment is compared to random level (i.e., 0.5). Accuracy greater than 0.5 was considered indicative of moral intuitive judgment. Single-sample t-test showed that the accuracy of the participants’ random responses was significantly greater than random (i.e., 0.5), indicating the existence of moral intuitions.

In Experiment 2, a total of 77 undergraduates were randomly assigned to two different conditions, i.e., moral relativism and moral absolutism. Participants were first primed moral absolutism or moral relativism by scrambling in a sentence, e.g., the scrambled sentence “as to rightness” “cannot” “different types of morality” “be compared” may be recomposed as “Different types of morality cannot be compared as to rightness”, then randomly answer “yes” or “no” to moral judgments. Independent-samples t-test showed that participants were more inclined to make moral intuitive judgments under the conditions of moral absolutism than moral relativism, which suggests that moral relativism weakens participants’ moral intuitive judgment, while moral absolutism promotes participants’ moral intuitive judgment.

In Experiment 3, a total of 80 undergraduates were randomly assigned to two different emotional conditions, i.e., disgust and neutral emotion. Participants’ disgust (or neutral emotion) were primed by eight pictures of disgusting facial expressions (or eight pictures of neutral facial expressions) before randomly answering “yes” or “no” to moral judgments. Independent-sample t-test showed that participants were more inclined to make moral intuitive judgments under the conditions of disgust emotion than neutral emotion, which suggests that moral intuition judgments are affected by emotion, and disgust increases individuals’ moral intuitive judgments.

In sum, the present research investigated the influence of moral relativism and disgust emotion on moral intuitive judgment, which helps to further understand the mechanism of moral intuitive judgment. In addition, it also provides some guidance for the daily moral judgment. The limitations and further research are also discussed.

Differential influence of sleep time parameters on preschoolers’ executive function
Shufen XING,Qianqian LI,Xin GAO,Yuanyuan MA,Rui FU
Acta Psychologica Sinica    2018, 50 (11): 1269-1281.   DOI: 10.3724/SP.J.1041.2018.01269
Abstract   HTML   PDF (642KB)

In China, disruptive sleep patterns and sleep deficiency are prevalent in preschool children. Literature has largely focused on the relationship between sleep duration and child development in adolescents and school-age children. Yet little is known about the impact of sleep duration in preschool children, for example, on their advanced neurocognitive function. Given that sleep need and sleep maturation develop rapidly in the first years of life, research findings in older children cannot be generalized to preschoolers.

Developmental research indicates individual differences in sleep need. From a developmental perspective, it is crucial to explore whether children’s susceptibility to neurocognitive disruptions is associated with sleep problems. Temperament, one aspect of individual susceptibility, is shown to be relatively stable across situations and developmental periods. In this study, negative emotionality in preschool children was used to indicate temperament. The goal of this study was to examine the links between preschoolers’ initial sleep duration (i.e., total daily sleep duration, ratio of nighttime sleep to total daily sleep, and sleep compensation over the weekend) and later executive function and the moderating role of children’s negative emotionality in the links. The sample was composed of 78 preschool children (Mage = 6.31 years, SD = 0.35) and their mothers. Total daily sleep duration, ratio of nighttime sleep, sleep compensation over the weekend, and child negative emotionality were assessed using parental sleep diaries and mother reports. Child executive function was measured three months later using a set of standardized measurement procedures offered by the National Institutes of Health (NIH).

The results of the present study indicated that controlling for children’s concurrent language ability, initial ratio of nighttime sleep significantly predicted children’s subsequent executive function. In addition, we found that negative emotionality significantly moderated the relation between sleep compensation and the three components of the executive function (working memory, inhibitory control, cognitive flexibility), in support of the differential susceptibility model. Specifically, sleep compensation was positively associated with performance in the executive function tests for preschool children with high negative emotionality whereas the association was nonsignificant for children with low negative emotionality.

In conclusion, our findings suggested that children who sleep longer at night would be more advanced in their EF development. For children with high negative emotionality, sleep compensation over the weekend has a positive effect on their executive function skills. The results of this study provided important practical implications for Chinese preschoolers’ sleep arrangements.

Neural processing of ambiguous Chinese phrases of stutters
LI Weijun, LIU Meng, ZHANG Zhenghua, DENG Nali, XING Yushan
Acta Psychologica Sinica    2018, 50 (12): 1323-1335.   DOI: 10.3724/SP.J.1041.2018.01323
Abstract   HTML   PDF (694KB)

Prosodic boundary is an integrative part of spoken language that segments ongoing utterance into prosodic units. These boundaries are correlated with the perception of a pause, a lengthening of the pre-boundary syllable and tonal movement at the end of the phrase. Stuttering is characterized by involuntary disruptions in the flow and rhythm of speech, which was reflected by repetitions of words, sounds or syllables, prolongations and silent blocks. Behavioral response and neural processing results in the past few years indicated that adults who stutters exhibit processing differences compared with fluent speakers during syntactic, semantic and phonological (rhyme) processing. However, existing studies did not examine whether stutters encounter difficulty during perception of prosodic boundary.

The present study aims to explore how stutters and fluent speakers process prosodic boundary of ambiguous Chinese phrases (Verb NP1 Aux NP2) in lexical and structural judgment task using ERPs. We used 168 typical ambiguous Chinese phrases as experimental materials. These phrases were temporarily ambiguous between modifier-noun construction (MNC) and narrative-object structure (NOS). Eighty-four phrases without ambiguity were used as fillers. Twenty-four (20 males) undergraduates/graduates participated in the experiment. They were told to listen carefully to pairs of phrase in two sessions with the same materials. In session one, they completed a lexical judgment task (to determine whether a visually presented word appeared in the pairs of phrase they heard), while in session two they were asked to complete a structural judgment task (to judge whether the pairs of phrase they heard belong to one kind of structure or not). Electrophysiological data were recorded by a set of 64 electrodes from eegmagine (ANT Neuro) according to the extended 10-20 positioning system. EEG data were time-locked to the offset of verb and Aux (de) of the first phrase using a 100-msec pre-stimulus baseline and an averaging time window of 800 msec. We selected two time windows (0~300 ms and 300~600 ms) for statistical analysis in the midline and lateral areas.

During 0~300 ms, we found that prosodic boundary (v.s. non-boundary) elicited positivity in the midline, F (1, 22) = 24.28, p < 0.001, ηp 2= 0.52, and lateral areas, F (1, 22) = 45.51, p < 0.001, ηp 2= 0.67. Besides, the interaction between Structure and Boundary was significant in the midline, F (1, 22) = 5.84, p < 0.05, ηp 2= 0.21, and lateral areas, F (1, 22) = 4.18, p = 0.053, ηp 2= 0.16. Simple effect analysis indicated that prosodic boundary elicited positive effect for MNC in the midline, while in the lateral areas prosodic boundary elicited positivity for both of NOS and MNC, F (1, 22) = 10.35, p < 0.005, ηp 2= 0.32; F (1, 22) = 29.69, p < 0.001, ηp 2= 0.57. During 300~600 ms, we found that prosodic boundary (v.s. non-boundary) elicited positivity in the midline, F (1, 22) = 36.61, p < 0.001, ηp 2= 0.61, and lateral areas, F (1, 22) = 36.59, p < 0.001, ηp 2= 0.71. Besides, the interaction between Region and Boundary was significant in the midline, F (2, 44) = 10.07, p < 0.005, ηp 2= 0.31, and lateral areas, F (2, 44) = 24.16, p < 0.001, ηp 2= 0.52. Simple effect analysis indicated that although the positivity elicited by prosodic boundary was broadly distributed in the whole scalp area, it was prominent in frontal-central area. More importantly, the interaction between Task, Boundary and Structure was significant in the lateral area, F (2, 44) = 3.95, p < 0.05, ηp 2= 0.15. Simple effect analysis indicated that in lexical judgment task, prosodic boundary of MNP elicited positive shift, F (1, 22) = 23.41, p < 0.001, ηp 2= 0.52, but NOS didn’t, F (1, 22) = 2.47, p = 0.131. However, prosodic boundaries of both MNP and NOS elicited positive effect in structure judgment task, F (1, 22) = 17.02, p < 0.001, ηp 2= 0.44; F (1, 22) = 11.65, p < 0.005, ηp 2= 0.35.

Overall, we found that stutters and fluent speakers exhibit similar neural process during prosodic boundary processing. This finding was reflected by the fact that the stable CPS was elicited by prosodic boundaries of both MNP and NOS. The positive effect elicited by MNC in an earlier time window was distributed more broadly in scalp than that elicited by NOS in both kinds of task. In a later time window, prosodic boundaries of both MNC and NOS elicited the stable CPS regardless of the kind of experimental task in the midline. In the lateral areas, the CPS was detected in the prosodic boundary of MNC in both kinds of task, whereas the CPS was stably observed at the boundary of NOS in structure judgment task. In conclusion, we contend that stutters and fluent speakers are both sensitive to prosodic boundary and their processing was influenced by the structure of ambiguous phrases and experimental task.

Language and culture influence cognition: Effects of indirect or direct language
YANG Qun,ZHANG Qirui,FENG Yiran,ZHANG Jijia
Acta Psychologica Sinica    2019, 51 (5): 543-556.   DOI: 10.3724/SP.J.1041.2019.00543
Abstract   HTML   PDF (892KB)

The relationship between language and color cognition is key to understanding language and cognition. With the arguments between linguistic relevance and linguistic universal hypotheses, researchers prefer the eclectic theory that color cognition includes physics, perception, and culture-related properties. Given these theories and various investigations, interaction theory between color terms and color cognition has been proposed. One argument suggests that color perception should be influenced by language and culture, given the normal sense organs and level of intelligence.
Numerous types of studies have proven that language and culture play a role in color cognition, but how such a role is performed remains to be fully understood. Discussions on the essential mechanism of this effect remain lacking, and whether this effect is a direct or indirect effect (i.e., language strategies or cognition structure changes) continues to be unclear. According to the literature, the color category perception effect proposes that people are more likely to distinguish colors from different colors than those that landed in the same area. Thus, two categories of color were used as materials in past research, which made it difficult to distinguish between the direct and indirect effects. Accordingly, this paper employed just one category color, which was further divided into two different categories. Color culture is import to a nation. Thus, green is vital to Uygur culture, with red as the counterpart for the Han culture. In relation to this, the present study designed a perceptual task (Experiment 1) as well as classification and recognition tasks containing memory (Experiments 2 and 3), in order to explore the effect of language and culture on color cognition for the Uygur and Han nationalities.
Focal colors of red (RGB: 0, 255, 0) and green (RGB: 255, 0, 0) were selected as base points, and a vertical demarcation line was drawn on the RGB chromatography. On each side of the line, nine different stimuli in the same lightness saturation level (240-120) but with different chromaticities were selected. In Experiment 1, three colors (two from the same side of green or red and another from the other side) constitute one set of experimental material. Participants were asked to judge as quickly and as accurately as possible whether the left or the right color block looked more similar to the middle one, and press the corresponding button on a response box. A total of 62 college students participated in the experiment (31 of Han nationality and 31 of Uygur nationality). In Experiment 2, the materials and the participants (in terms of number and categories) were identical to those in Experiment 1. Participants were instructed to remember the colors and identify as quickly and as accurately as possible whether the following colors belong to the left or to the right of the color pair, and then press the corresponding button on a response box. In Experiment 3, 62 participants from the two nationalities who were using identical materials were asked to judge as quickly and as accurately as possible whether the left or the right color looked more similar to the standard one, and then press the corresponding button on the response box.
Results showed significant differences in the perception, classification, and recognition tasks between the Uygur and Han nationalities. Compared with the Han nationality, the Uygur nationality had the advantage in distinguishing, classifying, and even recognizing green, but suffered a disadvantage when processing the color red. For the perception task, the two groups both spent a long time in the classification and recognition tasks. Accordingly, we believe that language and cultural differences in terms of perceiving the green and red colors affect color cognition and that such an effect is indirect, that is, language and culture can influence the color perception structure.

Impacts of chunking strategy on memorising similar words
ZHANG Lei,LU Chengrou,LIN Junfeng,MEI Leilei
Acta Psychologica Sinica    2019, 51 (3): 280-292.   DOI: 10.3724/SP.J.1041.2019.00280
Abstract   HTML   PDF (1009KB)

The successful memorisation of similar words is critical for individuals’ vocabulary acquisition. Previous studies have found that individuals perform significantly better in an immediate serial memory test for dissimilar words than similar words. However, the memory advantage for dissimilar words in those studies was mainly based on the comparison of two sets of different learning materials (i.e., similar and dissimilar words). Therefore, whether similar words are memorised better in a similar chunking condition (similar words are successively presented) or dissimilar chunking condition (similar words are alternately presented by other dissimilar words) is unclear.
To address the above question, we performed four experiments in this study, in which within-subject design and study-test paradigm were used. Experiment 1A aims to explore the effects of chunking strategy on the memory of similar words. In this experiment, two matched sets of similar English pseudowords were used for the similar and dissimilar chunking conditions, respectively. In the similar chunking condition, similar words were successively presented, whereas in the dissimilar chunking condition, similar words were alternately presented with other dissimilar words. Participants were instructed to memorise the words during the study phase. A recognition memory test was administered one hour after the study phase. Experiment 1B aims to investigate the memory advantage of the dissimilar chunking condition for long-term retention. Experimental materials and tasks were the same with those of Experiment 1A, but the interval between study and test was prolonged to one week. Experiment 2 used Deese-Roediger-McDermott (DRM) paradigm to examine whether the dissimilar chunking strategy facilitated the memory of similar words by improving the memory of individual words or enhancing the memory of shared parts across similar words. Experiment 3 included unfamiliar Korean characters as materials to further disentangle the contributions of visual and phonological similarities on the memory of similar words.
Results show that: 1) Compared with the similar chunking strategy, the dissimilar chunking strategy show better memory performance on similar words, which can be maintained for at least one week. 2) The dissimilar chunking strategy improves the memory of similar words and results in a high false memory for similar lures. 3) The memory advantage for dissimilar chunking strategy is evident for phonologically similar words (i.e., English pseudowords) but not for visually similar words (i.e., Korean characters).
The results suggest that the dissimilar chunking strategy improves the memorisation of phonologically similar words by enhancing the memory of common parts across similar words. In other words, the dissimilar chunking strategy may be an effective way to improve the memorisation of similar words. These findings have important implications for language learning and education.

Effects of orthographic depth on Chinese word naming for Han and Uyghur students
YANG Qun, WANG Yan, ZHANG Jijia
Acta Psychologica Sinica    2019, 51 (1): 1-13.   DOI: 10.3724/SP.J.1041.2019.00001
Abstract   HTML   PDF (464KB)

China is a multi-ethnic country with a variety of languages. Successful communication among nationalities is basic and important. Hence, bilingual education is a special teaching form in which ethnic minorities inherit the national culture and familiarize Mandarin and Chinese characters. As a typical alphabetic language, Uyghur differs from Chinese. Specifically, mastering the Chinese polyphonic characters is difficult for Uyghur students, especially those with more than one pronunciation. Orthographic depth denotes the consistency in grapheme-to-phoneme correspondence. In terms of inner language, polyphonic characters are less consistent than monophonic words. In relation to cross languages, orthographic depth affects the encoding of the lexical process. The present study aims to investigate the effect of orthographic depth on Chinese word naming tasks for Uyghur and Han nationalities.
The word naming task was conducted in experiments 1 and 2 to investigate the effects of orthographic depth. Thirty Han and thirty Uyghur students volunteered in each experiment, and each one participated in one experiment only. In experiment 1, eighty monosyllabic words with half poly and half monophonic characters were included. Among the poly and monophonic words, half reached high frequencies (343.3-3869.8/per million), and half had low frequencies (7.2-237.8/per million). During the experiment, the participants were asked to name words as quickly and accurately as possible. Repeated measure ANOVA was performed. The results corroborate that (a) naming latencies for polyphonic and monophonic words were longer for Uyghur than Han students, (b) monophonic words were named faster than polyphonic words for all the participants, and (c) the word frequency (WF) effect was larger for Uyghur than for Han students. Moreover, the authors recorded prepared responses using polyphonic words, which were pronounced with high frequency and named faster than the nondominant reaction but found no significant differences between the two groups.
In experiment 2, eighty disyllabic words were selected, with the first syllables equally grouped into polyphonic and monophonic characters. Among the disyllable words, half reached high frequencies (222.2-2565.4/per million), and half had low frequencies (2.3-47.6/per million). The procedure was similar to that in experiment 1.The authors performed repeated measures ANOVAs by subject and item and found an interaction between WF and orthographic depth in the two groups. For the Uyghur participants, words with initial polyphonic characters were named slower than monophonic ones in high frequency disyllable words. However, significant differences did not exist between polyphonic and monophonic characters. For the Han students, words with initial polyphonic characters were named slower than monophonic ones in low frequency disyllable words and displayed the same result with high frequency disyllable words.
The study validates that orthographic depth has different modes of influence on the naming of Chinese characters in the two nationalities. This finding is related to the differences in the characteristics of the mother tongue, the age of vocabulary acquisition, the level of language proficiency, and the manner of language processing between the two nationalities.

Linking abusive supervision with employee creativity: The roles of psychological contract breach and Zhongyong thinking style
SHEN Yimo,MA Chenlu,BAI Xinwen,ZHU Yanhan,LU Yunlin,ZHANG Qinglin,LIU Jun
Acta Psychologica Sinica    2019, 51 (2): 238-247.   DOI: 10.3724/SP.J.1041.2019.00238
Abstract   HTML   PDF (687KB)

Although creativity has been recognized as an important employee outcome related with work context, to date little research has examined the relationship between abusive supervision and employee creativity, which has perhaps been hindered by the lack of a theoretical framework outlining the mechanisms underlying this relationship. The current study examined the processes linking abusive supervision to employee creativity in the Chinese context by focusing on the mediating influence of psychological contract breach and the moderating influence of Zhongyong thinking style.
We collected data from 93 supervisors and 369 subordinates at three different time points. In the first survey, the subordinates were asked to provide information about abusive supervision and their demography. One week later, these subordinates were asked to answer some questions about psychological contract breach and Zhongyong thinking style. Approximately two months later, we asked these supervisors to rate their subordinates’ creativity. Multi-level structuring equation modeling technique and Monte Carlo resampling method were employed to examine the hypothesis about the moderating role of Zhongyong thinking style in the indirect relationship between abusive supervision and employee creativity through psychological contract breach.
These findings provided support for the hypothesis that the indirect relationship between abusive supervision and employee creativity through psychological contract breach is moderated by Zhongyong thinking style, such that the indirect relationship is weakened when Zhongyong thinking style is high, rather than low. These findings contribute to our understanding of the relationship between abusive supervision and employee creativity in the Chinese context, and imply that the negative influence of abusive supervision on employee outcomes could be decreased by guiding employees to cultivate Zhongyong thinking style because it can encourage self-regulation of behavior after experiencing abusive supervision.

How state anxiety influences time perception: Moderated mediating effect of cognitive appraisal and attentional bias
LIU Jingyuan,LI Hong
Acta Psychologica Sinica    2019, 51 (7): 747-758.   DOI: 10.3724/SP.J.1041.2019.00747
Abstract   HTML   PDF (785KB)

Anxiety is associated with high levels of arousal. Both theoretical and empirical work have determined that when an individual experiences anxiety, he/she shows attentional bias toward negative stimuli. High arousal and negative attentional bias, as the two key characteristics of anxiety, are associated with a series of subjective feelings and experiences of individuals with state anxiety, among which time perception is significant. However, how this process operates remains an open question. In this article, we investigate how state anxious individuals perceive time, especially the roles of attention bias and cognitive appraisal in this process.
Sixty college students participated in the study and were randomly assigned to a high state anxiety group (n = 30, completed a procedure of anxious state induction) and a low state anxiety group (n = 30, completed a procedure of calm state induction). Then, a 2 (high state anxiety group vs. low state anxiety group) × 2 (negative stimuli vs. neutral stimuli) × 3 (2000 ms vs. 4000 ms vs. 8000 ms) mixed-design experiment was conducted with the attentional bias as the mediator, the cognitive appraisal as the moderator and the time perception as the dependent variable. State anxiety was manipulated by an induction process, time perception was measured by the time reproduction task, attentional bias was measured by the dot-probe task and cognitive appraisal was assessed by the visual analogue mood scales.
The results showed that (1) State anxiety had an effect on time perception, namely, individuals with high state anxiety overestimated the 2-second interval of the negative stimuli. (2) Attentional bias played a partial mediating role in the relationship between state anxiety and time perception of 2000 ms. (3) Cognitive appraisal moderated the mediation effect of attentional bias on the influence of state anxiety on time perception of 2000 ms. Specifically, when the score of cognitive appraisal was high, attentional bias played a mediating role in the influence of state anxiety on time perception, while when the score of cognitive appraisal was low, attentional bias did not play a mediating role in the influence of state anxiety on time perception.
Therefore, the effect of state anxiety on college students’ time perception was a moderated mediating effect. The moderated mediating model significantly revealed the effect mechanism of state anxiety on college students’ time perception, which can contribute to a better understanding of how individuals in an anxious state perceive time. Furthermore, it suggests that the adjustment of cognitive appraisal or attentional bias is an important way to alleviate the time distortion of anxious individuals.

Eliminating the negative impact of subgroups by exchanging members in the subgroups
NI Xudong,JI Baile
Acta Psychologica Sinica    2019, 51 (2): 259-268.   DOI: 10.3724/SP.J.1041.2019.00259
Abstract   HTML   PDF (736KB)

The core of team research has shifted from team diversity to team faultlines and from faultlines to subgroups. In other words, the study of subgroups is the developmental direction of the study of team diversity and faultlines. Numerous studies have documented the negative effects of subgroups on group functioning, and scholars have explored whether team situations can eliminate such negative influence. However, no studies have explored whether the dynamic change of team composition at the subgroup level, such as subgroup member exchange, can eliminate this negative influence. This study aims to fill the research gap by focusing on this topic.
This research investigates teams with two balanced and identity-based subgroups as the research objects, and uses experimental research methods to explore whether subgroup member exchange can eliminate the negative impact of subgroups on team outcomes. By conducting experiments on 75 temporary teams (38 teams with subgroup member exchanges and 37 teams with no subgroup member exchange), this paper finds that (1) subgroup member exchange has a positive effect on team information elaboration and team decision quality and that (2) team information elaboration plays an intermediary role in the relationship between subgroup member exchange and team decision quality.
The theoretical contributions of this study are as follows: (1) it confirms whether variables at the subgroup level can eliminate the negative effects of subgroups on team functioning and proposes the concept of subgroup member exchange, and (2) it enriches the theory of CEM with subgroups involved in the path, which aims to develop team decision quality through information elaboration. The practical contributions of this study are two-fold. (1) It improves the ability of a team to solve complex tasks and managers can promote the movement of members among subgroups, such as providing them with the opportunity to work together, and valuing more interpersonal rather than inter-subgroup differences. (2) It increases team decision quality by allowing managers to create conditions to improve the degree of team information elaboration, such as fostering pro-diversity beliefs by communicating member’s belief in the value of diversity, and by explaining how task performance can benefit from the diversity of information and perspectives.
Although this research has provided theoretical contributions in subgroup research, numerous areas have yet to be explored. In the future, research on this topic can be improved by the following: (1) scholars can continue to explore how other changes in group composition can affect subgroup mechanism in the dynamic framework, and (2) scholars can continue to expand the CEM theory on subgroup backgrounds and investigate whether team information elaboration plays an active role in diversity, faultlines, and subgroups.

Acta Psychologica Sinica    2019, 51 (6): 648-661.   DOI: 10.3724/SP.J.1041.2019.00648
Abstract   HTML   PDF (777KB)

Emotion regulation provides an effective way to understand and control our emotion. The lack of emotion regulation skill is viewed as one of the major causes of emotional problems, such as depression, anxiety disorder and others. Researchers have attempted to find an effective way to improve individuals’ emotion regulation ability. In recent years, a promising direction is working memory updating, which is an essential element in the central executive component of working memory. Some studies suggest that working memory updating plays a critical role in modulating the emotion regulation process and that working memory updating training can enhance emotion regulation ability.

Thus, it is possible to improve depression-prone individuals’ emotion regulation ability through working memory training.

In order to examine the effect of working memory training on the emotion regulation ability of depression-prone college students, we used CES-D (Center for Epidemiologic Studies Depression Scale) and BDI-II-C (Beck Depression Inventory II Chinese) evaluation to recruit 40 depression-prone students and 20 healthy students. The depression-prone students were further divided into training and control groups voluntarily. The depression-prone training group completed a 20-day working memory training program. The depression-prone control group and healthy control group did not take part in the training. Participants’ scores for 2-back and 3-back tasks, Emotion Regulation Scale (ERS) scores, subjective emotion ratings for emotion regulation tasks, and HF (High Frequency Power) HRV (Heart Rate Variability) and LF (Low Frequency Power) HRV measurements for five conditions (resting, neutral, attending, relaxed and regulation) during pre-test and post-test phases were collected and analyzed. Statistical methods, including observation and variance analysis, were used to compare collected data from the three groups.

We found a significant main effect of condition on subjective emotion ratings. Participants’ subjective emotion scores for the regulation and attending conditions were significantly higher than those for the neutral condition. In addition, the emotion scores for the regulation condition were significantly lower than those for the attending condition. As for the HRV data, during the pre-test phase, the depression-prone training and control groups had no significant difference with respect to HF-HRV, and their HF-HRV was significantly lower than that of the healthy control group. As for the ratio of LF/HF-HRV, a significant condition × group interaction was found. Resting LF/HF-HRV of the healthy control group was significantly higher than that of the depression-prone training and control groups. During the post-test phase, there was a significant increase in HF-HRV for the depression-prone training group. HF-HRV for the depression-prone training group became closer to that of the healthy control group and was marginally significantly higher than that of the depression-prone control group. Moreover, HF-HRV for the depression-prone training group was significantly higher with respect to the regulation condition than the resting condition, while there was no difference for the other two groups. During the post-test phase, the ratio of LF/HF-HRV for the depression-prone training group was significantly higher than for the depression-prone control group, and there was no significant difference between the depression-prone training group and the healthy control group.

In conclusion, the HRV data for the depression-prone training group was more similar to that of the healthy control group during the post-test phase than that of the depression-prone control group, which indicated an improvement in emotional regulation ability. For future research, a larger sample size and a more sophisticated experimental paradigm for HRV data collection are needed.

The predictive effects of maternal life event stress in early childhood on 5-year-old child behavioral problems: A chained mediation model
HAO Yefang,WANG Zhengyan,DONG Shuyang,LIU Siman,WU Meng,LU Shan
Acta Psychologica Sinica    2019, 51 (1): 85-95.   DOI: 10.3724/SP.J.1041.2019.00085
Abstract   HTML   PDF (644KB)

As the primary caregiver, mothers have the most frequent interactions with children and display the most significant influence on children’s development. If mothers experience intense life event stress, they may create a stressful environment for their children’s early development. Living in such a developmental environment raises children’s risk of behavior problems in later childhood. Regarding the predictive effects of maternal stress on child outcomes, two compensatory models are differentiated in previous research: one is the direct effect model, which emphasizes on the direct impact of parenting stress on children’s maladjustment; and the other one is the indirect effect model, which focuses on the mediating roles of parenting practices and child self-regulation in the associations between parenting stress and child behavioral problems. However, in contemporary Chinese society, urban mothers face different sources of stress in their daily life. Maternal life event stress represents a more comprehensive and ecologically-validated assessment of maternal stress in the modern China, than maternal parenting stress assessed solely. But it is still unclear that whether those models about parenting stress are applicable to maternal life event stress. Based on Bronfenbrenner’s bioecological theory, we focused on the direct and indirect effects of maternal life event stress throughout infancy and toddlerhood on child behavioral problems at preschool in this longitudinal study. Three research questions were examined: 1) Which life events are the main stressors for urban mothers during their children’s infancy and toddlerhood periods; 2) Does maternal life event stress in these periods exert a long-term direct effect on preschoolers’ behavioral problems; 3) Does maternal life event stress also impact preschoolers’ behavioral problems through parenting practices and children’s self-regulation?
107 families (50 boys and 57 girls) were recruited from the local communities and child care clinics in urban areas of Beijing. During this five-year longitudinal study, questionnaires were distributed to the mothers at five waves of assessments. At 9, 14, 25, and 38 months, data on maternal life event stress were collected through maternal reports on the Life Event Scale. When children were 61 months, mothers rated children’s behavioral problems and prosocial behaviors by the Strengths and Difficulties Questionnaire and child effortful control by the Children’s Behavior Questionnaire-Short Form, and reported their positive parenting practices on the Alabama Parenting Questionnaire.
The results showed that the most frequent negative life events included housing shortage, stress from work and studying, family members being seriously ill or injured, problems with spouse's parents, difficulty with caring for the child, and low quality in marital relationship. Although the correlation coefficients between the maternal life event stress at the adjacent time points were moderate, the top ranked stressor varied slightly when children were at the different ages. At 9 months, housing shortage ranked the highest, whereas at 3 years old, difficulty with caring for the child ranked the highest, and the stress from low quality in marital relationship rose up. Furthermore, structural equation models showed that maternal life event stress across 9 to 38 months impacted children’s behavioral problems at 61 months in two ways. First, there were direct effects of maternal life event stress on preschoolers’ emotional symptoms and conduct problems. Second, the indirect effects included that the indirect effect of maternal life event stress on preschoolers’ emotional symptoms and peer problems through maternal positive parenting practices, and the chained mediating effect through maternal positive parenting practices and then child effortful control between maternal life event stress and preschoolers’ hyperactivity problems and prosocial behaviors.
This study indicated two underlying mechanisms of maternal life event stress throughout early development on preschoolers’ behavior problems, including the direct influence and indirect influence through positive parenting practices and child effortful control. These findings suggested that children’s development was impeded in an early developmental environment where mothers were suffering from the stresses of intense negative life events, particularly for children’s emotional regulation and behavioral conduct. Besides, the alternative indirect mechanism has also been found that positive parenting practices and child effortful control were disrupted by maternal life event stress, which, in turn, increased children’s risks of attentional deficit symptoms and antisocial behaviors. The current study, thus, provided the empirical support for the non-negligible harm to children’s adjustment from maternal life event stress in early childhood. Overall, maternal life event stress might increase the risk of behavior problems. This alerts us that it is necessary to identify the high-risk families in the community samples and conduct effective intervention as early as possible.

Daily negative affect and emotional labor strategies
FANG Yanran,WEI Wei,LUO Ping,LIU Xiaodong,SHI Junqi,ZHAN Yujie
Acta Psychologica Sinica    2019, 51 (3): 353-365.   DOI: 10.3724/SP.J.1041.2019.00353
Abstract   HTML   PDF (818KB)

Emotional labor refers to the process of regulating both feelings and expressions in response to the display rules for promoting organizational goals. Instead of conceptualizing emotional labor as a stable behavioral tendency, the current study applied self-regulation theory to understand emotional labor (expressing proper emotion at work) as a self-regulation process, and specific emotional labor strategies (i.e., deep acting and surface acting) as approaches employees use to cope with negative moods on a daily basis.
By surveying 210 customer service representatives of a call center for fourteen consecutive workdays, this diary study examined a multilevel model of daily emotional labor, with morning negative affect as a within-person level predictor, and employee job tenure and emotional intelligence as between-person level moderators. Specifically, the main effects of daily negative affect on emotional labor strategies were reflected by mean values of the random slopes at the within-person level. To test the cross-level interactive effects, the random slopes of “morning negative affect-daily emotional labor strategies” relations were regressed on job tenure and emotional intelligence; the interactive effects were indicated by significant effects of between-level moderators on given within-level random slopes.
Results showed that service employees were more likely to engage in deep acting on days when they experience lower levels of negative mood. Further, job tenure and emotional intelligence significantly attenuated the negative effect of morning negative affect on daily deep acting. Specifically, the negative relationship between morning negative affect and daily deep acting was weaker (versus stronger) for employees with longer (versus shorter) job tenure, or higher (versus lower) emotional intelligence. Additionally, employees’ emotional intelligence also moderated the relationship between morning negative affect and surface acting, but in different directions. To be concrete, for employees with higher emotional intelligence, there was a positive relationship between morning negative affect and daily surface acting; whereas the relationship reflected a negative trend for employees with less emotional intelligence.
The current study contributes to the literature of emotional labor in several aspects. First, drawing on self-regulation theory, the current study conceptualized emotional labor as a coping strategy in employees’ daily self-regulation process. In conceptualizing deep acting and surface acting as coping strategies consuming different levels of resources, the current study provided a resources-based mechanism underlying the “negative affect-emotional labor strategy” linkage. Second, the current study also investigated cognitive resource (i.e., job tenure) and self-regulation resource (i.e., emotional intelligence) at the individual level as boundary conditions that shape the impact of daily negative affect on emotional labor strategies. In doing so, we were able to support the resource-based theoretical mechanism between the “negative affect-emotional labor strategy” linkage, and expand the literature on emotional labor.

Effect of childbearing deadline on women’s wanted fertility
XING Cai,MENG Yuqi,LIN Qingqing,QIN Ziyu
Acta Psychologica Sinica    2019, 51 (4): 428-436.   DOI: 10.3724/SP.J.1041.2019.00428
Abstract   HTML   PDF (579KB)

The transition to ultra-low level of fertility in China has become a major challenge to its sustainable development. As the population of reproductive-aged women will continue to decline in the upcoming years, enhancing women’s childbearing motivation is important and urgent to avoid further decline of fertility rate. This work is the first attempt to examine the effect of childbearing deadline on women’s childbearing motivation. With socioemotional selectivity theory, life-span theory of control, and previous findings about the ending effect in the field of decision making as basis, this work aims to examine the causal link between women’s childbearing deadline and motivation.

Three studies were conducted in this work. The first study used an online questionnaire to examine the relationship between the time left women perceived before their childbearing deadline and their childbearing motivation. Women who perceive they are closer to their childbearing deadline reported higher childbearing motivation. The second study, which was conducted in laboratory settings, examined the causal effect between these two factors by manipulating women’s perception of optimal childbearing deadline. Participants were randomly assigned to two experimental conditions: limited and extended. Participants who were told that women’s optimal childbearing deadline is 26 fell under the former condition, and those who were told that the deadline is 32 fell under the latter. Participants’ baseline childbearing motivation served as another independent variable. Participants completed an implicit association test with pictures of babies and baby animals served as stimuli. They also completed a brief questionnaire in which they answered three questions concerning their childbearing motivation. An interaction effect between childbearing deadline and baseline childbearing motivation emerged in the reaction time of the implicit association test. Simple effect analyses revealed that participants with higher baseline childbearing motivation showed greater increase in their childbearing motivation compared with those with lower baseline childbearing motivation. Participants in the limited condition showed greater increase in their childbearing motivation compared with those in the extended condition. Participants in studies 1 and 2 were young single women. Study 3 tested this effect among married women who were aged below 40 with one or no child. Half of them were primed with a childbearing deadline, whereas the other half were in the control condition. Participants primed with a childbearing deadline showed greater number of wanted fertility, which further supported the findings in studies 1 and 2. This work marks only the beginning. When and how does childbearing deadline influence women’s childbearing motivation should be further explored.

Does mobile shopping make fast decisions? The role of contextual factors and thinking style
Minxue HUANG,Wei WANG
Acta Psychologica Sinica    2019, 51 (5): 612-624.   DOI: 10.3724/SP.J.1041.2019.00612
Abstract   HTML   PDF (985KB)

Previous studies have proposed that firms attempt to reduce online shopping choice deferral, which may lead consumers to abandon or drop their shopping carts before making their final purchase. Moreover, given their mobility and tactile effects, the use of mobile devices can make consumers more emotional compared with the use of desktop computers, thereby triggering a decision-making process. However, the results of some surveys reject such case and instead reveal that the decision-making process of consumers is influenced by the interaction between contextual factors and product attributes. In this paper, these contextual factors were classified into mobile devices and personal computers, while product attributes were classified into low price and high price. Inspired by dual-process theory, we supposed that high (low) price might evoke the rational (experiential) thinking styles of consumers and that mobile devices (personal computers) could trigger their experiential (rational) thinking styles. When these thinking styles are triggered by price and device types, the online choice deferral of these consumers will be reduced.
We performed two studies to verify these hypotheses. In Study 1, we collected 3, 674 order data from the Tmall online shopping platform for around two months with the cooperation of a wine company based in China. The threshold regression analysis of secondary data showed that the shopping terminal (mobile phones and personal computers) had no main effect on online shopping choice deferral. However, these results highlighted a significant interaction between product price and device type. As predicted in hypothesis 1, the results indicate that online consumers have significantly more choice deferral for a low-price product when shopping using their personal computers than their mobile phones. Meanwhile, these consumers have significantly more choice deferral for high-price products when shopping using their mobile phones than their personal computers. We also conducted a laboratory experiment to test our hypotheses and verified the mediating effect of thinking style by bootstrapping. We recruited 138 participants in Study 2. Our 2 (device type: mobile phone vs. personal computer) × 2 (price level: low vs. high) between-subject design showed that these participants had significantly lower tendency of choice deferral for low-price products when using mobile phones than when using personal computers. On the contrary, these participants showed a significantly lower tendency of choice deferral for high-price products when using personal computers than when using mobile phones. The mediating effect of thinking style was also verified.
The results suggest that online shopping choice deferral is affected not only by product attributes (such as price level in this paper) but also by specific situations (such as device type in this paper). High- (low-)priced products may evoke the rational (experiential) thinking styles of these consumers, while mobile devices (personal computers) can trigger their experiential (rational) thinking styles. When the thinking style is triggered by the product price and device, the online choice deferral of these consumers can be reduced. On the contrary, triggering these two thinking styles at the same time can increase their online shopping choice deferral.
The theoretical contributions of this research are as follows. First, this study offers a deeper understanding of the consumer shopping scenario by showing that different types of devices can trigger different thinking styles, thereby extending the current perspectives toward mobile shopping. Second, this study enriches the previous research on choice deferral by exploring the situational effect on the decision-making process. Third, this study extends the current understanding of the experiential and rational thinking styles by examining the relationship between these two styles, thereby contributing to dual-process theory. The findings of this study can also help companies improve their scenario-based target marketing.

Effects of facial attractiveness and information accuracy on preschoolers’ selective trust
TANG Weihai,ZHONG Rubo,XU Xiaoxu,LIU Xiping
Acta Psychologica Sinica    2019, 51 (1): 71-84.   DOI: 10.3724/SP.J.1041.2019.00071
Abstract   HTML   PDF (652KB)

The research area on children’s selective trust in testimony was initiated by Harris et al. (2014). Previous studies had found that knowledge, as a trustworthy source, is conditional. In addition, the certainty of new information that is decided by the knowledge cues can influence children’s selective trust. Bascandziev and Harris (2014) found that four- to five-year-old boys in an ask task did not show biased selective trust to an informant with a high facial attractiveness when they were learning new information. However, the difference in facial attractiveness was possibly not detected by the children and the children’s age was not controlled. Therefore, the aim of Experiment 1 was to find the characteristics of selective trust on the basis of facial attractiveness when children acquire new information. The goal of Experiment 2 was to examine whether information accuracy or facial attractiveness is the main factor influencing children’s selective trust.
Experiment 1 adopted a 3 (age group: four-, five-, six-year-old children) × 2 (gender: male, female) × 2 (task: ask, endorse) mixed design. A total of 63 four-year-old children (Mage = 54.72 months, SD = 2.06 months, 30 girls) and 66 five-year-old children (Mage = 66.00 months, SD = 1.47 months, 33 girls) were selected from two kindergartens in Tianjin. In addition, 66 six-year-old children (Mage = 78.12 months, SD = 1.80 months, 30 girls) were selected from an elementary school in the same city. Experiment 2 adopted a 2 (accuracy of information: 50% vs. 50%, 25% vs. 75%) × 3 (age group: four-, five-, six-year-old children) between-subject design. A total of 62 four-year-old children (Mage = 54.72 months, SD = 3.17 months, 28 girls) and 59 five-year-old children (Mage = 66.48 months, SD = 3.59 months, 27 girls) were selected from two kindergartens in Tianjin. Moreover, 56 six-year-old children (Mage = 78.12 months, SD = 1.80 months, 27 girls) were selected from an elementary school in the same city. All children in the two experiments participated in ask and endorse tasks using a laptop computer to selectively trust one of two informants with different levels of facial attractiveness.
The results of Experiment 1 revealed that four- to six-year-old girls and boys show selective trust to informants with high facial attractiveness in the ask and endorse tasks. Moreover, five-year-old children have stronger degree of selective trust to informants with high facial attractiveness than four-year-old children. No difference was found between five- and six-year-old children and between four- and five-year-old children. Girls were stronger than boys in the ask task, no difference between was found between them in the endorse task. The results of Experiment 2 revealed that four- to six-year-old children in equal- and unequal-accuracy conditions show selective trust to informants with high facial attractiveness when they completed ask task. Moreover, no difference was found among the three age groups on the degree of selective trust to informants with high facial attractiveness. However, when they completed the endorse task, children in the equal-accuracy condition did not show any preference to informants with high or low facial attractiveness. By contrast, children in the unequal-accuracy condition tended to selectively trust informants who had low facial attractiveness but mentioned more accurate names. However, no difference was found among the three age groups on the degree of selective trust to informants with low facial attractiveness.
On the basis of these results, this study proposes the following: (1) Girls and boys aged four-six years show selective trust on the basis of facial attractiveness if the information is deficient. Moreover, girls aged four to six years are more venerable to social bias factors than boys of the same age range. (2) Four- to six-year-old children can make rational judgments on the reliability of the information provided by informants if the information is sufficient.

Preview processing of between words and within words in Chinese reading: No word highlighting effect
GUAN Yiyun, SONG Xini, ZHENG Yuwei, ZHANG Yingliang, CUI Lei
Acta Psychologica Sinica    2019, 51 (9): 969-981.   DOI: 10.3724/SP.J.1041.2019.00969
Abstract   HTML   PDF (923KB)

In the present study, readers’ eye movements were recorded to investigate the influence of word highlighting information on the preview processing of between-words and within-words.

Most studies on preview effects have found that the size of the preview effects is 30~50 ms. Hy?n? et al. (2004) examined parafoveal processing of the end lexeme of a long Finnish compound while the beginning lexeme of the compound was fixated. And the results found 80ms preview effect which was more pronounced than previous literatures. The larger preview benefit may have been due to the fact that the preview word is part of one larger linguistic unit (within-words); however, in previous experiments, the preview word and the current fixated word belong to different words (between-words). Consequently, researchers speculated that within-words might induce larger preview effect than that of between-words. Some researchers used compound words (within-words) and phrases (between-words) to further explore this issue and they found that there were no differences between within-words and between-words in preview effects. The results cannot exclude the possible explanation that larger preview effect for within-words is caused by the higher syntactic expectations of nouns comes from adjectives in phrases inducing larger preview effect and then counterbalances the possible differences between the two kinds of words. The present study adopted the boundary paradigm to probe the preview processing differences between within-words and between-words. In the present study, the first character of a two-character compounds (between-words) and the second character of a two-character compounds (within-words) was manipulated to be presented normally or replaced by a pseudo-character for previews. Moreover, word highlighting sentence and non-word highlighting sentence were introduced to examine whether the word boundary information could exert different influences on the preview processing of between-words and within-words. Marking word boundary by word highlighting has its unique advantages. Most of all, compared with word spaces, word highlighting can not only keep the same sentence length meanwhile providing the word boundary information but also control the same word lateral masking on different conditions.

Firstly, the results indicated that the preview effect for between-word was smaller than that of within-word. The results were consistent with the results of Hy?n? et al. (2004), which showed that the morphological information of target word could impact on preview processing. Secondly, we found that there were no differences among normal condition, highlighting condition and non-word highlighting condition. Even so, we did not found the significant influences of word boundary demarcation for preview processing, the possible benefit effect of word boundary still could not be ruled out thoroughly. As Bai et al. (2008) pointed out that readers are familiar with the text without any word boundary signals in normal reading; consequently, the null effect between normal and word boundary text may show a priming effect on word boundary condition, which is the one readers are not familiar with. Thirdly, the results showed that word boundary information had similar effects on within-words and between-words.

Results of the present study indicated that word morphological information could affect its preview processing; however, word boundary information do not necessarily facilitate preview processing for both between-words and within-words. The possible explanation may be that word segmentation and word recognition occur simultaneously. These results are consistent with the model of word segmentation and word recognition.

Distinct effects of age of acquisition in Chinese object and action picture naming: An ERP study
LOU Hao,LI Cong,ZHANG Qingfang
Acta Psychologica Sinica    2019, 51 (2): 143-153.   DOI: 10.3724/SP.J.1041.2019.00143
Abstract   HTML   PDF (705KB)

Age of Acquisition (AoA) refers to the age at which a concept is learned. Early-acquired words have an advantage over late-acquired words in processing accuracy and speed. Which stage of AoA playing its role in spoken word production remains controversial. The phonological completeness hypothesis assumes that AoA may have a phonological locus, while the semantic hypothesis assumes that AoA affects semantic processing (i.e., conceptual preparation, lexical selection). The network plasticity hypothesis assumes that AoA arises at multiple processing levels, in spoken word production.
In a picture naming task, we used the event-related potential (ERP) technique to examine the loci of AoA effect in object and action pictures naming. Twenty-eight participants (9 males, mean range: 22.18, SD: 2.56) participated in this study. We selected a total of 188 words and their corresponding black and white line pictures, half of which were object pictures, and half were action pictures. Within each type of picture, half were early acquired, and half were late acquired. Therefore, the age of acquisition of picture names (early vs. late) and word type (noun vs. verb) served as within-participants variables. During the experiment, participants were asked to name each picture as accurately and quickly as possible.
Behavioral data indicated a typical AoA effect in object pictures naming, showing that object pictures corresponding to early-acquired nouns were named faster than those corresponding to late-acquired ones. In contrast, action pictures corresponding to early-acquired verbs were named slower than those corresponding to late-acquired verbs. ERP data also showed distinct AoA effect patterns in object and action picture naming. For object picture naming, late-acquired nouns elicited a larger positivity than early-acquired nouns between 250~300 ms over left-prefrontal regions. In contrast, for action picture naming, early-acquired verbs evoked a larger positivity than late-acquired verbs within 200~250 ms, 300~400 ms and 450~600 ms time windows over the left hemisphere.
We suggest that the AoA effect in object naming may originate in the lexical selection of spoken word production, supporting the semantic hypothesis. In contrast, the AoA effects in action naming may originate in multiple processes, such as lexical selection, phonological encoding and phonetic encoding, supporting the network plasticity hypothesis. The distinct AoA effects between the naming of object and action pictures probably relate to the distinct semantic networks that represent objects and actions. Therefore, the AoA effect in action picture naming is much more complicated than in object picture naming and needs further investigation.

Quality or price? The effect of stock-out middle option on consumer choices
YAO Qing, CHEN Rong
Acta Psychologica Sinica    2019, 51 (5): 625-636.   DOI: 10.3724/SP.J.1041.2019.00625
Abstract   HTML   PDF (441KB)

Consumers in real world sometimes face situations in which information about unavailable products is still present in the decision contexts. For example, consumers may find that certain options are sold out and thus marked by an out-of-stock stamp in such a way that consumers can still examine their attributes information. Traditional models of consumer choices have assumed that the addition of an unavailable alternative to a choice set has no impact on the shares among the original alternatives. However, recent studies on asymmetrical dominance choice sets suggest that adding an alternative that asymmetrically dominates a targeted alternative and is declared to be unavailable increases preference for the target in the original choice set. Three categories of theories, range-weighting, similarity-substitution and relative-advantage, have been used to explain the phenomenon.
Despite prior research interest in extending attraction effect in unavailability context, little is understood about how unavailable options influence preferences among available options in other choice settings. Dominant literature have advocate for the preference for the compromised option in a three-option set. Thus, it is typical that the unavailable option is the compromised one. The above three explanations all fail to predict the preference on the remaining options in this situation.
We propose that consumers are experiencing increasing decision difficulty or feeling greater conflict deciding in the unavailable compromise set than in the two-option set, and thus are likely to alleviate this negative task-related emotion by engaging in conflict-reducing heuristics. In particular, if choice of the compromise option that is associated with smallest maximum error or likelihood of being criticized is impossible, consumers forced to make difficult trade-offs among extremes are likely to rely more on the unambiguous attribute in the evaluations, because unambiguous outcome is associated with a lower likelihood of criticism. Thus, consumers seek to guarantee (avoid) advantages (disadvantages) of their selected option in precision rather than in ambiguity. Based on findings that attributes in quantitative nature (e.g., price) are easier to trade-off than attributes (e.g., quality) in qualitative nature, we predict that the relative preferences for low-quality, low-price option which has a precise and certain advantage will be stronger in presence than in absence of an unavailable intermediate option.
Study 1 establishes that the addition of an unavailable compromise option into a two-option local set can increase the relative share of the cheaper option. In Study 2, we demonstrate that the degree to which the quality advantage (disadvantage) can be ambiguously evaluated moderates this effect. When the value of quality becomes less ambiguous to evaluate (providing experts’ quality evaluations, Study 2A) or more ambiguous to evaluate (describing product quality by a range of performance, Study 2B), the effect that the cheaper option fares better in the unavailable middle option set attenuates or strengthens. Study 3 further examines the underlying mechanism by testing the moderating effect of consumer product knowledge, and the mediating effect of decision conflict. We conclude with a discussion of the theoretical and managerial implications.
