    Visual working memory (VWM) and selective attention are two essential topics of investigation in the field of cognitive psychology. Previous studies have suggested that object-based attention selection modes may be present during the VWM encoding stage, and feature-based attention selection modes may be present during the maintenance stage. Nonetheless, these conclusions are based on different research paradigms, object feature dimensions, and response indicators, so it is prudent to exercise caution when inferring the existence of distinct attention selection modes during different stages of VWM processing. The aim of the present study is to evaluate this hypothesis and provide empirical support.

    In Experiment 1a, 30 college students were recruited to complete a change-detection task. Participants were instructed to memorize the features of the objects presented in the memory display by means of a pre-cue or retro-cue presented prior to or following the memory display. Specifically, in pre-cue trials, participants were asked to memorize only the cueing task-relevant feature while ignoring the task-irrelevant feature. In retro-cue trials, participants needed to memorize the entire object so that they could select the task-relevant feature according to the retro-cue. The present study examined the “irrelevant-change distracting effect” by comparing memory performance between the condition of task-irrelevant feature changes and no-changes on the memory probe test display. Experiment 1b had a similar procedure, except that the cue types were block designs. Based on the design of Experiment 1b, Experiments 2 and 3 increased the number of memory items to test whether the memory load would modulate the attention selection modes. Twenty-eight participants were recruited for Experiment 1b, Experiment 2, and Experiment 3. All experiments were 2 (cue types: pre-cue, retro-cue) × 2 (task-irrelevant feature change types: change, no-change) within-subjects designs, participants’ response times (RTs) and correct rates were recorded, and the sensitivity and criteria of the participants were calculated by signal detection theory (SDT).

    The results of the three experiments showed that the change in task-irrelevant features had an impact on task performance in the pre-cue trials, with longer RTs and lower criteria in the task-irrelevant feature change condition than in the no-change condition. This distracting effect was not modulated by the memory load. This suggests the existence of robust object-based attentional selection during the encoding stage in VWM. In contrast, in the retro-cue trials, the distracting effect was present only in the low memory load condition (Experiment 1a/1b) and disappeared when the memory load increased (Experiment 2/3). This suggests that during the maintenance stage, task-irrelevant features are processed only under low memory load conditions, and insufficient resources lead to their inability to be processed as the demand for attentional resources for task-relevant features increases.

    In summary, the present study provides further evidence for the hypothesis that different modes of attentional selection exist in the encoding and maintenance stages of VWM, specifically that the attention selection mode during the VWM encoding stage is object-based, while the attention selection mode during the maintenance stage is feature-based and regulated by memory load. This study has important implications for resolving the controversy surrounding the attention selection mode of multifeature objects in VWM.

    A new generation of interactive models, called digital voice assistants (DVAs), can respond to young children's speech requests automatically and interact with them by voice. Research on the development of young children's epistemic trust in DVAs is scarce. Previous research has concentrated on the development and influencing factors of young children's epistemic trust in human informants or traditional electronic media (e.g., computers, webpages, internet). The semisocial nature of these devices determines the specific theoretical and practical value of investigating young children's epistemic trust in DVAs. Based on this, the purpose of the current study was to investigate the epistemic trust of young children (aged 3-6) and adults in DVAs in various domains and to confirm the significance of accuracy in their trust.

    The paradigm of dual-informant sources was employed in both experiments. A sample size of 88 children was required for an effect size of w = 0.30, 1 - β = 0.8, α = 0.05, according to G*Power 3.1. In Experiment 1, 30 adults and 90 children aged 4-6 were given testimony from distinct information sources (DVAs vs. humans) in either the natural or social domain to investigate the children's willingness to ask questions, explicit trust judgments, and final endorsements. Whereas the natural domain involved a task to label novel things, the social domain involved inquiry into social customs. The accuracy of the informants was manipulated in Experiment 2, which was based on Experiment 1, and 90 children aged 3-5 and 30 adults were exposed to various informants.

    The research participants were asked questions about their willingness to ask, explicit trust judgments, and final endorsements. The results of Experiment 1 showed that the children preferred to ask the DVAs questions about the natural domain rather than the social domain, with the DVAs being preferred overall. Moreover, the 6-year-old children preferred the DVAs as the information source more than the 4- to 5-year-old children. The adults were more likely to trust the DVAs than the young children. The results of Experiment 2 revealed that the children of all ages and adults were more likely to accept correct informant testimony in both the natural and social domains. In other words, the children were more likely to use the current accuracy of informants as a cue to assess and decide which informant to trust, and when the DVAs lost their accuracy, the children's preference disappeared along with their intellectual trust. The preference for accurate informants was more obvious in the adults and 4- to 5-year-olds than in the 3-year-olds, with the 3-year-olds being less sensitive to accuracy. Accuracy was an essential indicator of the DVAs' dependability.

    Our study is the first to investigate the development of epistemic trust in DVAs among children aged 3-6 in China. The results show that children can use DVAs as a source of information and knowledge. Young children become more likely to believe the testimonies of DVAs as they grow older. Children are more likely to trust DVAs in the natural domain than in the social domain. Furthermore, young children are more likely to accept the testimony of reliable informants. The results of this study may contribute to our understanding of the usability and utility of human interaction with technological systems and offer suggestions for the use of DVAs in homes and classrooms to support early learning.

    The preference and development for societal-type cues in 3- to 8-year-olds’ perception of groups
    WANG Yang, WEN Fangfang, ZUO Bin
    2023, 55 (9):  1424-1440.  doi: 10.3724/SP.J.1041.2023.01424

    Perception of groups develops from an early age. Previous studies focused on groups with perceptual- salient cues like gender and race. As highlighted in the intuitive theories of social categorization, children perceive social groups as natural kinds or serving functional roles of social obligation. However, the priority of these two aspects affecting children’s group perception is yet to be explored. Our current research summarized these two aspects into physical-type and societal-type cues. Physical-type cues are identified by perceptual- salient attributes related to people like color, gender, and socioeconomic status (SES). Societal-type cues reflect shared attitudes, beliefs, and values among group members, such as common interests, group belongings, and norms. It has previously been found that children start to endorse prescriptive norms around age five. Therefore, we assume that children’s preferences for societal-type cues will increase across ages 3 to 8, with a critical period of 5 to 6 years of age.

    Study 1 was tested online. A total of 215 children (108 males) ages 3 to 8 were recruited. Three physical-type and three societal-type cues were paired under nine experimental conditions. Two tasks were conducted in random order between the participants: The Triad Classification Task and the Exclusion Task. Both tasks required participants to categorize targets based on one of the two given cues (each represented by one cue-type). In the Triad Classification Task, children needed to select one target from two peers, and in the Exclusion Task, they needed to exclude one target. Study 2 tested 3- to 8-year-old children offline (3- to 4-year-olds: 32 children; 5- to 6-year-olds: 21 children; 7- to 8-year-olds: 20 children). Six cues were combined into two experimental conditions (gender × color × norm vs. SES × common interest × belonging). Children were tested using the Opening Social Categorization Task, in which they categorized eight targets into two groups, and reported the reasons for categorization.

    Results of the two studies demonstrated that 3- to 8-year-olds could apply physical-type and societal-type cues to group perception. Specifically, children rely more on societal-type cues than physical-type cues as they grow up. The 3- to 4-year-olds preferred societal-type cues in social categorization tasks with two choices (Study 1), and physical-type cues in tasks offering three choices (Study 2). Children aged 5 to 8 displayed preferences for societal-type cues in the tasks of Study 1, whereas showed no cue preferences in Study 2. Therefore, for young children (3- to 6-year-olds), their preferences for societal-type cues were sensitive to the number of cues provided in the social categorization tasks, and offline versus online measurements. Moreover, children’s cue-type preferences differed significantly between 3- to 4-year-olds (preferred physical-type cues) and 7- to 8-year-olds (preferred societal-type cues). Thus, the critical period for developing a preference for societal cues was 5 to 6 years of age.

    This study constructs a new framework of physical-type and societal-type cues to understand children’s social categorization and group perception. These two types of cues reflect children’s perceptual and conceptual foundation in their social categorization. Across ages, children’s ability to apply physical-type and societal-type cues supports the intuitive theory of social categorization that children are naturally perceived as groups from two aspects. Physical and societal aspects may be the basic dimensions of group perception. Future research could extend the present findings to other social categories, and more importantly, provide more neurobiological evidence for children’s biases toward societal-type cues.

    The association between transgressor’s remorse and victim’s forgiveness among young children: The activation effect of bystanders
    CHEN Guanghui, LI Yihan, DING Wen, CHEN Jing, ZHANG Liang, ZHANG Wenxin
    2023, 55 (9):  1441-1452.  doi: 10.3724/SP.J.1041.2023.01441

    Humans are extremely social beings, and we attempt to repair our ruptured relationships when transgressions occur that damage interpersonal cooperation. The expression of guilt and remorse by the transgressor and the forgiveness by the victim are both vital to the repair process. To some extent, transgressors’ remorse is the most prominent elicitor of victims’ forgiveness. Previous studies have demonstrated that forgiveness emerges as early as 5 years old and that young children are capable of forgiving a remorseful transgressor even in the absence of an explicit apology. Given the emphasis on relationship harmony among Chinese people in a collectivistic culture, parenting and socialization might help children understand peers’ remorse intentions and forgive them at a much earlier age. Furthermore, the high need for personal reputation and social image in peer interactions, which is called “face” (mianzi) by the Chinese, might lead to individuals’ forgiveness decisions being influenced by bystanders who witness or participate in group interactions. Therefore, this study aimed to investigate whether 4- or 5-year-olds could have the capacity to infer an apology from displays of transgressors’ remorse in order to reveal the influence of remorse on forgiveness and further explore the activation effect of different types of bystanders among the association between remorse and forgiveness.

    Study 1 was a one-factor (expression of remorse: remorse vs. no remorse) within-subject design. Forty-nine children aged 4 to 5 years (27 girls) were investigated by a classic paradigm of remorse and forgiveness. The “tear picture” game was used to create conditions of expressing remorse and not expressing remorse. Then, children were asked ten questions designed to assess whether they understood the true intention of remorse. Finally, the resource distribution task was used to assess forgiveness behavior. In Study 2, a total of 139 4- to 5-year-old children (80 girls) were recruited to participate in a 2 (expressions of remorse: remorse vs. no remorse) × 4 (types of bystander: no bystander vs. teacher vs. good friend vs. stranger) mixed experimental design. The procedure used in Study 2 was identical to that used in Study 1.

    The results showed that: In Study 1, both 4-year-old children and 5-year-old children truly understood the intention of the expression of remorse, and they were much more forgiving of a remorseful transgressor than of a transgressor who had not shown remorse. In Study 2, although children were still more forgiving of a remorseful transgressor than an unremorseful transgressor in the presence of bystanders, bystanders significantly increased the level of forgiveness shown toward unremorseful transgressor and reduced the level of forgiveness for remorseful transgressor. Specifically, for remorseful transgressor, child victims were more forgiving of a transgressor while in the presence of strangers than while in the presence of teachers or good friends; however, for unremorseful transgressor, child victims who were being observed by teachers or good friends showed more forgiveness behavior than did victims who were being observed by stranger bystanders. Furthermore, the results showed that young children were more likely to equally distribute flowers to remorseful and unremorseful transgressor in the presence of bystanders, especially teachers or good friends.

    This study successfully revealed that young Chinese children could accurately understand the intention of transgressors’ remorse and thus be willing to perform forgiveness behavior at age 4, which is exactly 1 year earlier than their counterparts in the Western sample. More importantly, we also present a new theoretical hypothesis, namely, the “bystander-activation effect of social expectations”, to propose that the presence of bystanders activates individuals’ socially desirable behaviors, such as “requite injury with kindness” and “egalitarianism”, in the Chinese collectivist culture. Thus, it is easier to understand why bystander onlooking could increase the level of forgiveness for unremorseful transgressor and cause young victims to distribute flowers to remorseful and unremorseful transgressor equally. Furthermore, the greater the authoritative or intimate level of bystanders is, such as teachers or good friends, the stronger the activated social expectations are and the more socially desirable the engaged-in behaviors are. This study provides important enlightenment for understanding the association between remorse and forgiveness and for rethinking the cross-cultural differences in children’s socialization.

    “Attraction of the like”: The influence of peer’s donation choice on prosocial behavior of adolescents and the role of the belief in a just world
    ZHANG Weiwei, CHEN Yiqun, ZHU Liqi

    Social influence refers to the process by which the thoughts, feelings, and behaviors of individuals are directly or indirectly influenced by others. Adolescents’ social behavior is easily influenced by peers. However, most of the previous studies on peer effects have focused on the negative aspect of peer influence, such as peer influence on adolescent aggressive behavior, antisocial behavior, and risk-taking behavior, whereas the positive effects of peers have received relatively less attention. Existing work has not reached consensus on whether adolescents' prosocial behavior is more likely to be influenced by altruistic peers or egoistic peers, and the underlying mechanism is also unclear. The present study focuses on the positive effects of peers. Furthermore, the impact of different information providers is also an issue examined in this study. Given that children in Chinese culture are more subordinate to authority, Chinese adolescents may be more influenced by adults than peers. The belief in a just world may also play a moderating role in the peer influence, which would be explored in this study.

    The present study used the adaptive behavioral experimental paradigm and the conflicting source paradigm in developmental research on selective trust to investigate the effects of social information (prosocial, selfish, conflict) provided by peers or adults on adolescents’ donation behavior at real cost, and the role of the belief in a just world in it. The sample included 77 adolescents aged 12-15 years (Mage = 14.06 ± 0.74 years, 32 girls). The specific setting of the adaptive paradigm was as follows: under the condition of prosocial influence, the decision of the peer observed by the participants was always more altruistic than their initial decision; similarly, under the condition of selfish influence, the decision of the peer was more selfish than their initial decision. In other words, the amount of donation that participants observed was determined by their initial donation.

    The results showed that the secondary donation after viewing the peer’s decision was more altruistic than the initial donation in both the prosocial and the conflict conditions, while the difference between the two rounds of donation was not significant in the selfish condition, which indicates that the prosocial behavior of adolescents was more susceptible to prosocial influence. In addition, compared with the conflict condition and the selfish condition, the second donation of the participants in the prosocial information condition changed the most, which again confirmed the reliability and stability of the results. Moreover, adolescents were more likely to be influenced by information provided by peers than that provided by adults: adolescents changed their donation amount more in the peer influence condition than in the adult influence condition. We further focused on the performance of participants in the conflict condition: when adolescents observed both prosocial information and selfish information, their secondary donations were more likely to change in the direction of altruism, and this transition was more likely to occur in the peer influence condition, which indicates that adolescents are more likely to be influenced by peer role models than by adult role models. The belief in a just world moderated the prosocial influence of adolescents: individuals with high belief in the just world were more likely to be affected by positive social influence.

    The results indicate that adolescents are more likely to be positively influenced by peers. This study expands the theory of social learning theory, reveals the benefit of peer moral models on adolescents' prosocial behavior, and provides reference for improving the educational practice of adolescents' prosocial behavior.

    Changes in the network association of Internet addiction among heterogeneous high-risk adolescents
    CHEN Shiyun, QU Diyang, BU He, LIANG Kaixin, ZHANG Peichao, CHI Xinli

    The China Internet Information Center reported that the internet addiction rate among Chinese adolescents has reached as high as 10%, indicating that this problem has become a major social health concern among adolescents in China. Previous studies have identified one or more subgroups of adolescents whose trajectory of internet use behaviors puts them at a high risk of addiction, but further research is needed to determine and understand these high-risk groups and fill research gaps. Furthermore, most previous studies have approached the problem from the perspective of the variables of internet addiction, but its symptomatology remains poorly understood. The current study combines a growth mixture model (GMM) with network analysis to identify heterogeneous groups of adolescents at a high risk of internet addiction and to explore the changes in symptomatology in these groups.

    A three-year longitudinal study followed students from the time they entered junior high school. Three assessments were conducted yearly at identical intervals (T1: October 2016 to November 2016, T2: October 2017 to November 2017, and T3: October to November 2018). Ultimately, 1, 279 adolescents (662 boys and 617 girls) completed the assessments at each time point. Internet addiction was assessed using the 10-item Internet Addiction Test. Mplus 8.0 was used for the descriptive statistics, correlation analysis, and the GMM to estimate the development trajectories of various heterogeneous groups. An R package was used to estimate the network structure and core symptoms of internet addiction of each high-risk group at each time point.

    The GMM showed a normal group and a high-risk group, which consisted of adolescents who were heterogeneous in terms of the development trajectory of internet addiction. Network analysis revealed that the core symptoms of Internet addiction among the adolescents in the high-risk group differed at each time point. In the first year of junior high school, “Compulsive Internet Use”, “Lack of Satisfaction”, “Emotional Outbursts”, and “Withdrawal Symptoms” were the core symptoms. In the second year, “Lack of Satisfaction” was the core symptom, and in the third year, “Withdrawal Symptoms” became the core symptom.

    This study enhances the understanding of the symptomatology of Internet addiction among high-risk adolescents, indicating that targeted interventions must be developed based on the various stages of adolescence. From the first year of junior high school, strategies should be implemented to prevent the development of Internet addiction in high-risk groups. In the second year, adolescents in the high-risk group should be identified by focusing on their satisfaction deficits. In the last year of junior high school, interventions should target adolescents’ withdrawal symptoms of Internet addiction.

    Combined effects of distal and proximal interpersonal stress and FKBP5 gene on adolescent self-injury behavior: The developmental perspective
    BAI Rong, GAO Yemiao, LI Jinwen, LIU Xia

    Self-injury usually emerges in early adolescence and has a high incidence among adolescents worldwide. Self-injury not only damages body tissue but is also associated with depression, anxiety, personality disorders, substance abuse, and a higher-than-average risk of suicide. Given the high incidence of self-injury and the severity of its consequences, it is important to explore its predictors and specific mechanisms. Interpersonal theories of developmental psychopathology maintain that interpersonal stress is a critical risk factor for adolescent self-injury behavior. However, the ways the source and duration of exposure to that stress affect adolescent self-injury behavior are unclear. Adolescents also differ in their sensitivity to interpersonal stress. Stress-related genetic factors may play an important moderating role. The current study selected child abuse and recent peer victimization as distal and proximal interpersonal stress, respectively, and FKBP5 gene rs3800373 polymorphism as the genetic factor. The purpose of this study was to build upon the results of previous studies by exploring the relative and interactive effects of distal and proximal interpersonal stress on adolescent self-injury behavior.

    The participants were 436 adolescents (12.84 ± 0.89 years, 49.8% males) recruited from four junior high schools in Guizhou Province. All were tracked from grade 7 to grade 9. At Time 1, adolescents reported child abuse via the Parent-Child Conflict Tactics Scale, reported peer victimization via the Multidimensional Peer Victimization Scale, and reported self-injury behavior via the Short Version of Self-Injury Behavior Scale. At Time 2, adolescents reported peer victimization and self-injury behavior, and saliva samples were collected. Genotyping with respect to the FKBP5 gene was performed with Agena MassArray software, and the corresponding typing results were analyzed using MassARRAY Typer software version 4.0.

    Results showed that both distal and proximal interpersonal stress significantly predicted adolescent self-injury behavior, but the relative effect sizes differed in early and middle adolescence. Across the entire sample, distal and proximal interpersonal stress had an interactive effect on adolescent self-injury, and the interaction pattern was consistent with the stress amplification model. However, when the FKBP5 gene was considered, the interaction pattern was found to differ between adolescents in different genotype groups. Specifically, compared with AA homozygous adolescents who experienced less childhood abuse, those who experienced more child abuse were easily to be impacted by recent peer victimization and engage in NSSI. This was consistent with the stress amplification model. However, in adolescents with the AC/CC genotype who experienced more childhood abuse, mild recent peer victimization triggered adolescent self-injury. These participants showed lower self-injury thresholds and higher scores for self-injury than those who experienced less childhood abuse, which was consistent with a stress sensitization model. These relationships were stable in both early and middle adolescence.

    These findings showed different patterns of interaction between interpersonal and intrapersonal factors on self-injury behavior in adolescents of different genotypes. Using an integrative, dynamic, and developmental framework, this study provides important insights into the relevant interpersonal theories. It is also valuable for the accurate identification of adolescents at high risk of self-injury and for both prevention and intervention.

    Moderating effects of CSF3R and action control between stress and healthy eating: Preliminary evidence for an individual health action against stress model
    HU Yueqin, WANG Lizhong, CHEN Gang, GAN Yiqun

    A healthy diet is essential to maintaining a healthy lifestyle, yet many factors may hinder a healthy eating plan. Some studies have found that people tend to consume more unhealthy foods to cope with stress. But the opposite findings also exist. Some people under stress may still maintain a healthy diet. The mechanisms by which people make different dietary choices under stress are not yet clear.

    This study combined health behavior theories and vagal tone theory and proposed a gene stress interaction model of dietary choice, arguing that different dietary choices under stress may be related to two types of vagal tone: trophotropic or ergotrophic, representing the tendency to regenerate and recover or the tendency to prepare for fight or flight. CSF3R is a granulocyte colony-stimulating factor receptor that is closely associated with chronic psychological stress responses, and its different genotypes may lead to different stress responses, exhibiting the aforementioned tendency toward or away from nutrition. In addition, action control suggested by HAPA (Health Action Process Approach) may also play a critical role in the implementation of healthy eating intentions into healthy eating behaviors.

    A sample of 14675 Chinese adults completed genotyping of their saliva samples, as well as questionnaires on perceived stress, action control, and healthy dietary intentions and behaviors. CSF3R was used as a candidate gene reflecting vagal tone due to its proven impact on stress response. Regression analysis was used to test the effect of stress on healthy dietary intentions and behaviors, and the moderating effect of the CSF3R gene and action control.

    Results found that stress predicted a significant reduction in healthy dietary intentions and a subsequent reduction in healthy dietary behaviors. The CSF3R gene rs4076431 and its linked loci rs4498771, rs10752589, rs9660229 moderated the relationship between stress and healthy eating intentions, while action control moderated the relationship between healthy eating intentions and behaviors. In rs4076431, for example, the negative relationship between stress and healthy eating intentions was stronger in AA genotype (trophotropic) than the G carriers (ergotrophic). And higher levels of action control were associated with more healthy eating behaviors and less indirect impact of stress on behavior.

    These results supported the individual health action against stress model, which may be applied to healthy diet education and stress management. Individual's stress levels reflecting environmental influence, dominance of vagal tone (or genotype) and action control reflecting individual physiological and psychological factors may all have an impact on dietary choices.

    Autistic traits influence pain empathy: The mediation role of pain-related negative emotion and cognition
    ZHANG Wenyun, ZHUO Shiwei, ZHENG Qianqian, GUAN Yinglin, PENG Weiwei
    2023, 55 (9):  1501-1517.  doi: 10.3724/SP.J.1041.2023.01501

    Individuals with autism spectrum disorders (ASD) are typically characterized by impaired social interactions that are thought to be related to deficits in empathy. While cognitive empathy deficit in ASD is widely recognized, it remains controversial whether individuals with ASD have a deficiency in emotional empathy. According to the shared representation theory, psychological and neuronal mechanisms involved in the personal experience of an emotional or somatosensory state are also engaged while empathizing with other individuals in those states. It suggests that the deficits of empathy seen in the ASD population could arise from the atypical experience of first-hand pain. Mild, subclinical forms of the characteristics associated with ASD are referred to as autistic traits. Individuals with high autistic traits exhibit sensory, emotional, and social behaviors similar to those with ASD. Given the relationship between pain empathy and first-hand pain as well as the similarity between autistic traits and ASD, the present study tested the hypothesis that autistic traits in the general population would influence pain empathic responses, which could be contributed by first-hand pain-related profiles.

    In Experiment 1, we adopted an ecological pain empathy paradigm and compared behavioral and neural activity between individuals with high scores on the Autism-Spectrum Quotient Test (HAQ, with high autistic traits) and those with low scores (LAQ, with low autistic traits). During the pain empathy paradigm, the participants either perceived the painful electrical stimuli themselves or witnessed the delivery of painful electrical stimuli to their partners in certain and uncertain contexts. When perceiving pain themselves, behavioral and brain responses were comparable between HAQ and LAQ groups. When witnessing others in pain, participants in the HAQ group had greater amplitudes of the P2 component on the event-related potentials and reported higher ratings of unpleasantness than those in the LAQ group. The between-group differences in the behavioral and neural responses related to pain empathy were not moderated by certainty of the context (certain or uncertain). Mediation analysis further revealed that the between-group differences in the unpleasantness elicited by witnessing others’ pain could be contributed by the greater fear of pain while anticipating the upcoming painful stimuli.

    In Experiment 2, the relationship among autistic traits, pain-related profiles, and trait empathy was assessed in randomly recruited participants. We found that autistic trait levels were negatively correlated with scores on the perspective-taking subscale of the Interpersonal Reactivity Index and positively correlated with the personal distress subscale. Importantly, pain-related fear and pain catastrophizing mediated the link between autistic traits and personal distress.

    Data from Experiments 1 and 2 demonstrated that autistic traits heighten emotional empathy, which can be explained by the negative emotion and cognition toward pain. Given the similarities between individuals with high autistic traits and ASD, this finding may help to expand the biological mechanisms underlying ASD, such as explaining empathy deficits or other social difficulties seen in the ASD from the perspective of atypical pain-related profiles. Future studies should combine multiple modalities of painful stimulations and multidimensional pain assessments to comprehensively characterize pain-related profiles among individuals with high autistic traits or ASD, and establish linkage between pain-related profiles and empathy or social deficits. This understanding has the potential to provide targets for clinical interventions and treatments of ASD.

    People often infer others’ social traits, such as trustworthiness, from a glance at their face. Whereas previous studies have focused on how different facial cues influence social perception, the present study examined whether perception of a person’s trustworthiness could influence mental representations of that person’s face, as well as the mechanisms underlying this process.

    Two experiments were conducted. Experiment 1 was designed to test whether a target person described as trustworthy would be represented in the perceiver’s mind as more attractive than the same person described as untrustworthy. Participants were instructed to form an impression about a target person’s trustworthiness by viewing the person’s face paired with a description labeling them as trustworthy or untrustworthy. The reverse correlation image classification (RCIC) technique was then used to visualize the participants’ mental representations of the target person’s face. A separate group of participants was recruited to evaluate the attractiveness and other traits of the generated mental representation images. Experiment 2 aimed to determine a possible underlying mechanism by exploring whether the mental representations of the trustworthy (or untrustworthy) target persons’ faces in Experiment 1 shared more similarities with those of the trustworthy (or untrustworthy) faces at a group level (i.e., prototypes of trustworthy or untrustworthy faces). To achieve this goal, we recruited participants to complete an alternate RCIC task in which they selected which of two faces appeared more trustworthy, producing mental representation images for trustworthy and untrustworthy faces at a group level. The features of these prototypical trustworthy and untrustworthy faces were then compared with those of the target person from Experiment 1.

    In Experiment 1, mental representations of a face described as trustworthy were found to be more attractive than those of the same face described as untrustworthy. Furthermore, raters attributed additional desirable traits, such as friendly, intelligent, and positive, to the representation of the trustworthy person. In Experiment 2, we found that the mental representation of the face labeled as trustworthy in Experiment 1 shared more similarities with the prototypical trustworthy face produced in Experiment 2 than with the prototypical untrustworthy face.

    In sum, our findings suggest that the perception of a person’s trustworthiness can influence mental representations of that person’s face. When people perceive an individual as trustworthy (or untrustworthy), they may superimpose the corresponding schema features in their minds onto the physical characteristics of the perceived individual’s face, leading to a reconfiguration of the face representation. Our study underscores the importance of top-down factors in shaping face representations.

    Change or procrastination? Employees’ differentiated responses to illegitimate tasks
    ZOU Yanchun, ZHANG Huimin, PENG Jian, NIE Qi, WANG Zhen
    2023, 55 (9):  1529-1541.  doi: 10.3724/SP.J.1041.2023.01529

    Illegitimate tasks refer to tasks that are in violation of what employees feel can reasonably be expected from them. Illegitimate tasks can be differentiated into unreasonable and unnecessary tasks. To date, several empirical studies have revealed the negative effects of illegitimate tasks on employees, such as lower job satisfaction, poor psychological detachment from work, lower self-esteem, and stronger feelings of resentment. Given the detriments of illegitimate tasks, how should employees respond to them? Surprisingly, prior research has mainly focused on employees’ negative responses, such as counterproductive work behaviour and turnover intention. Only one study has found that employees can respond to illegitimate tasks proactively (e.g., task crafting). Integrating these ongoing research streams, we propose a dual model of illegitimate tasks. In doing so, we provide a balanced perspective for understanding differentiated responses for illegitimate tasks.

    To explore how employees respond to illegitimate tasks, we draw on the approach-avoidance model to hypothesize the following: For employees who have a high level of approach tendency, illegitimate tasks facilitate their taking charge behaviours as a means of improving the work situation. Felt responsibility for constructive change accounted for the above moderating effect. In contrast, for employees who have a high level of avoidance tendency, illegitimate tasks cause their procrastination at work as a means of keeping away from such a situation. Work alienation accounted for the moderating effect.

    To test our theoretical model, we carried out an experiment. The experiment showed that approach tendency and illegitimate tasks positively interacted to facilitate taking charge behaviour and that avoidance tendency and illegitimate tasks positively interacted to facilitate work procrastination. In addition, we recruited a variety of full-time employees to participate in the survey. The final sample included 207 three-wave data. Regression analysis was used to test our hypotheses. The results not only replicated the interactive effects again but also revealed that felt responsibility for constructive change played a mediating role in the interaction between approach tendency and illegitimate tasks, while work alienation played a mediating role in the interaction between avoidance tendency and illegitimate tasks.

    Our findings demonstrate that approach-oriented employees respond to illegitimate tasks in a positive way, whereas avoidance-oriented employees respond to illegitimate tasks in a negative way. In addition, our findings advance the approach-avoidance model by applying this model on the field of illegitimate tasks. In practice, our research provides implications for managers to manage illegitimate tasks according to employees’ psychological tendencies. If illegitimate tasks are unavoidable, organizations should pay more attention to promoting employees’ approach tendency and felt responsibility for constructive change.

    The effect of product traditional cultural load on brand status: Evidence from young consumers
    YU Wenhuan, HE Lin, FU Yu, LIU Tao
    2023, 55 (9):  1542-1557.  doi: 10.3724/SP.J.1041.2023.01542

    Culture has important social attributes. Previous studies have shown that adding traditional cultural attributes to a product, i.e., increasing the product’s cultural load, can improve consumers’ evaluations of the product. However, it is unclear how this affects brand evaluations. We infer that adding traditional cultural attributes to a product may increase the perceived social value of the product and, in turn, improve consumers’ evaluations of the status of the brand to which the product belongs. Furthermore, this positive effect may be stronger for utilitarian than for hedonic products.

    Four behavioral studies and one brain-imaging study were conducted. Study 1 used a one-factor design with traditional cultural load (low vs. high) as the between-participant factor to examine the main effect of the traditional cultural load on brand status evaluations. Study 2 used a 2 (traditional cultural load: low vs. high) × 2 (product type: utilitarian vs. hedonic) between-participant design to assess the boundary of the main effect. Study 3a and 3b adopted a one-factor between-participant design to confirm the uniqueness of traditional culture by comparing it with modern culture (high-modern culture vs. low-traditional culture vs. high-traditional culture) and traditional Western culture (high-traditional Western culture vs. low-traditional culture vs. high-traditional Chinese culture), respectively, and also to reveal a mediating role of perceived social value. Finally, Study 4 used a one-factor within-participant design (low traditional culture load vs. high traditional culture load) to confirm the main effect and the mediating role of perceived social value again in an offline experiment. In addition, brain activations of a subset of participants in Study 4 were also measured throughout the experiment using functional near-infrared spectroscopy.

    The results of Study 1 showed that increasing the traditional cultural load of a product can improve the perceived status of the brand. Study 2 found the boundary of this effect. Compared to hedonic product brands, utilitarian product brands are more likely to be affected by the traditional cultural load of products. Increasing the traditional cultural load helps to increase the status of utilitarian product brands. Furthermore, the results of Study 3 and Study 4 suggested that the positive effect of product traditional cultural load on brand status is mainly due to the increase in perceived social value. Study 4b found that only in the multi-person social scenario did brain regions associated with social and reward processing show higher levels of activation.

    Our theoretical contribution is threefold. First, this research deepens the understanding of the traditional cultural load of products and establishes the link between the traditional cultural load of products and brand status. Second, it unravels the influence of the social attributes of traditional culture on the social value of the product, making it a key mediator in explaining the increase in brand status. Third, we reveal the limitations of using traditional culture in brand management. In addition, our research findings have important practical implications for guiding domestic brands to enhance their brand status.

    Like knows like: The effect of social identity conflict on preference for integrated culturally mixed products
    PANG Jun, LI Menglin
    2023, 55 (9):  1558-1572.  doi: 10.3724/SP.J.1041.2023.01558

    Culturally Mixed Products (CMPs) refer to products embodying components from two or more cultures. These products can be categorized into two distinct types: intrusive and integrated, based on the degree of harmonious coordination and minimal cultural intrusion. The present research centers on integrated CMPs, which are more prevalent than intrusive CMPs in everyday life. Considerable research has examined what factors influence consumer responses to integrated CMPs. This research expands the existing body of literature by introducing social identity conflict as a contextual factor that may enhance consumer preference for such products. We posit that social identity conflict elicits a self-verification motive that integrated CMPs can satisfy due to their perceived congruence with the self. We further conjecture that the positive influence of social identity conflict on preference for integrated CMPs will be attenuated when consumers acquire products for functional rather than symbolic purposes, and when they purchase products for others rather than themselves.

    We implemented six studies to evaluate our hypotheses. Study 1a assessed participants' chronic experiences of social identity conflict and their preferences for an integrated CMP or a regular product. Study 1b manipulated participants' social identity conflict and asked them to choose between an integrated CMP and a regular product. Study 2a’ procedure was similar to that of study 1b, with three exceptions. First, we added an identity-synergy condition. Second, we employed the same stimuli as in study 1b, but asked participants to rate their preferences rather than make a choice between the two products. Third, we measured emotions, cognitive flexibility, novelty-seeking, self-concept clarity, and perceived product value in self-verification to investigate the underlying mechanism. Study 2b sought to further substantiate the underlying process with a 2 (social identity conflict: activated vs. not) × 2 (alternative means to self-verification: provided vs. not) between-subjects design. For participants provided an alternative means to self-verification, we asked they to recall and write down a person who could accept their conflicting social identities. Studies 3 and 4 employed a 2 × 2 between-subjects design to examine the moderating roles of purchase goal and purchase recipient, respectively.

    In line with our predictions, studies 1a and 1b demonstrated that social identity conflict heightened consumer preference for integrated CMPs. Study 2a corroborated self-verification as the underlying mechanism. Study 2b offered additional evidence by indicating that the focal effect would be diminished when consumers possessed alternative means of self-verification. Study 3 revealed that social identity conflict increased the preference for integrated CMPs only when consumers procured products for self-expression, with this moderating effect mediated by the perceived value of products in self-verification. Study 4 established that the focal effect only existed when consumers purchased products for themselves rather than for others.

    This research contributes to the CMP literature by recognizing a novel precursor of consumer preference for integrated CMPs and elucidating the role of self-verification in this relationship. More broadly, this research enhances the understanding of how social identity conflicts shape consumer behavior. From a practical standpoint, our findings provide valuable insights into marketing strategies for integrated CMPs.

    Joint cognitive diagnostic modeling for probabilistic attributes incorporating item responses and response times
    TIAN Yashu, ZHAN Peida, WANG Lijun
    2023, 55 (9):  1573-1586.  doi: 10.3724/SP.J.1041.2023.01573

    Compared with the conventional CDM with deterministic or binary attributes, the CDM with probabilistic attributes (probabilistic-CDM) can achieve a more refined diagnosis of attribute mastery status, which helps distinguish individual differences between students and provides more reference information for teacher feedback. However, existing probabilistic CDMs can only analyze a single modal of data—item response accuracy (RA), ignoring other modals of data such as item response times (RTs). RTs reflect the cognitive processing speed of the participant. With the popularity of computerized testing, recording RT data has become routine. However, how to use RTs in probabilistic CDM to further improve parameter estimation accuracy and enrich the diagnostic feedback information is still an unsolved methodological problem. To this end, the current study proposes three joint probabilistic CDMs based on the joint-hierarchical and joint-cross-loading cognitive diagnostic modeling approaches.

    First, based on joint-hierarchical modeling, the joint-hierarchical probabilistic CDM (JRT-PINC) was proposed in Study 1, which achieved the purpose of using RT to improve diagnostic accuracy. A simulation study was conducted to investigate the psychometric performance of the JRT-PINC under various simulated testing conditions, in which three independent variables, including sample size, test length, and the correlation between person parameters, were manipulated. Second, two joint-cross-loading probabilistic CDMs (CJRT- PINC-θ and CJRT-PINC-m) were proposed based on the joint-cross-loading modeling. In contrast to the JRT-PINC model, two CJRT-PINC models directly used RTs to provide information for latent abilities or attributes by introducing item-level cross-loading parameters. Two CJRT-PINC models released some conditional independence assumptions in JRT-PINC, increasing their application scope. Two simulation studies were conducted to explore their performance under different simulated conditions with different degrees of cross-loading. Third, Study 3 aims to explore the relative merits of the JRT-PINC and two CJRT-PINC models, that is, the necessity of considering cross-loading in the joint analysis of RA and RT. Finally, an empirical example was conducted to illustrate the practical applicability of the proposed models and to compare them with existing CDMs (e.g., CDMs with deterministic attributes).

    The simulation results mainly indicated that: (1) all three proposed models can be well recovered under different simulated conditions; (2) CJRT-PINC-θ makes fuller use of the information contained in RTs and thus improves the accuracy of the parameter estimation of the core constructs (e.g., latent ability and attributes) than CJRT-PINC-m; and (3) the adverse effects of ignoring the possible cross-loadings are more severe than redundantly considering them. The results of the empirical example indicated that: (1) probabilistic attributes provide more refined feedback on participants' mastery of attributes than deterministic attributes; and (2) two CJRT-PINC models fit this data better than the JRT-PINC model.

    Overall, this paper introduced RTs in probabilistic CDM for the first time and proposed three joint probabilistic CDMs based on two joint cognitive diagnostic modeling approaches. This study enriched the scope of application of probabilistic CDMS and provided methodological guidance for further refined and comprehensive diagnosis by jointly analyzing multi-modal data in technology-enhanced assessment systems.
