The role of stroke nodes in the recognition of handwritten Chinese characters ZHU Yiming, ZHAO Yang, TANG Ning, ZHOU Jifan, SHEN Mowei 2023, 55 (12):  1903-1916.  doi: 10.3724/SP.J.1041.2023.01903 Abstract ( 1594 )   HTML ( 209 )   PDF (997KB) ( 1986 )   Peer Review Comments Generative theory holds that the recognition of visual graphics is the inverse reasoning of its generation process. Chinese characters are hieroglyphs formed by interlacing strokes according to orthographic rules. Chinese character recognition can be regarded as the reverse reasoning of the generation process of Chinese characters. Based on the typical generative model -- Bayesian program learning model, the recognition of Chinese characters starts from recognizing the strokes. Firstly, the nodes are extracted based on the intersection of lines, and then all the stroke combination modes that can generate the node are enumerated to obtain the generation mode of Chinese characters. According to the above prediction, the number of nodes and node complexity are important factors in the process of Chinese character recognition. This study investigated the role of nodes in Chinese character recognition through three experiments. If the nodes provide guidance information for stroke segmentation, the more nodes, the better the performance of Chinese character recognition. In Experiment 1, we tested whether characters with more nodes have recognition advantages by adopting a 2×2 within-subjects design and using 76 single characters as the materials. Characters were chosen from two groups (high node-count and low node-count) of true characters, and two groups (high node-count and low node-count) of fake characters. The characters were briefly presented (10 ms, 20 ms, 30 ms, 40 ms, 50 ms, 60 ms) and appeared once at each presentation time. The presentation order of stimuli was completely random. Each participant completed a total of 456 trials. Twenty-six participants joined in the experiment. After observing each character, the participants reported whether it was a true character or a fake one. If high complex nodes in a larger stroke space provide more information, covering high complex nodes will cause greater interference to character recognition. In Experiment 2, we tested whether characters covered the high complex nodes are harder to recognize by adopting a 2×2×4 within-subjects design and using 160 compound characters covering a node as the materials. Characters were chosen from four groups (covering the first node with high or low complexity and the fifth node with high or low complexity) of true characters, and four groups of fake characters with the same conditions. The process was the same as that of Experiment 1, except the presentation time (60 ms, 70 ms, 80 ms, 90 ms). Twenty-nine participants joined in the experiment. Each participant completed 640 trials. Experiment 3 adopted a task similar to Experiment 2, and added two variables: component type and node generation method. The presentation time was 60 ms. Characters were chosen from eight groups of true characters, and eight groups of fake characters with the same conditions. Each stimulus is presented once. Twenty-six participants joined in the experiment. The accuracy and reaction time (RT) of true characters were analyzed in all experiments. The results showed that the participants had a better recognition performance for the characters with more nodes (node number effect), and covering the high complex nodes significantly damaged their performance (node complexity effect). In Experiment 1, the accuracy of recognizing characters with more nodes was higher and the response time was lower. The repeated-measures ANOVA of accuracy and RT found that the main effect of the number of nodes was significant. The interaction between the number of nodes and presentation time was significant. When the stimulus presentation time were 40 ms and 50 ms, node number effect was more pronounced. In Experiment 2, the accuracy of recognizing characters covering the high complex nodes was lower. The repeated-measures ANOVA of accuracy found that the main effect of the complexity of nodes was significant. The interaction between node complexity and node order is significant. Node complexity effect was more pronounced when covering the fifth nodes. In Experiment 3, we also found that the main effect of the complexity of nodes was significant. The interaction between node complexity and node generation method is significant. These findings support the nodes provide bottom-up stroke separation guidance information. Stroke separation was performed in parallel, for the more nodes a character has, the more information provided for the stroke segmentation, and therefore the character would be easier to recognize. And stroke separating began with the extraction and analysis of nodes, for the more complex nodes are, the greater impact on recognize. This study deepens the understanding of the early visual process of Chinese character recognition and supports Chinese character recognition is a generative reverse reasoning process, which could contribute to develop a complete cognitive model of Chinese character recognition.

How the dimension of negative emotional motivation influences time perception: The mediating role of attention control and attention bias YIN Huazhan, ZHANG Li, LIU Pengyu, LI Dan 2023, 55 (12):  1917-1931.  doi: 10.3724/SP.J.1041.2023.01917 Abstract ( 3047 )   HTML ( 308 )   PDF (515KB) ( 4063 )   Peer Review Comments In the research about the effect of emotion on time perception, researchers focus on the effects of valence and arousal. However, the inconsistent results found that the effect of emotion on time perception could not be fully explained only from the perspective of valence and arousal. Gable introduced the factor of emotion motivation to investigate the effect of emotion on time perception. How motivation influences time perception has gradually become a major scientific problem. However, the mechanism by which the dimensions of emotional motivation affected time perception remained unclear. In the present study, we explored the effect of dimensions of negative emotional motivation on time perception and its potential mechanisms (attention control and attention bias) based on the direction of negative emotional motivation and intensity of withdrawal-motivation emotion. The present research included two studies. Study 1 recruited 62 college students and explored the influence of the negative emotional motivation direction (approach-motivation emotion, withdrawal-motivation emotion, and neutral stimulus) on time perception. Study 2 recruited 61 college students and explored the influence of the intensity of withdrawal-motivation emotion (high intensity, low intensity, and neutral stimulus) on time perception. In the two studies, emotional pictures were used to induce the direction and intensity of emotional motivation.; the point detection paradigm was used to measure attentional bias; the Flanker task was used to measure attention control; and the time reproduction task was used to measure time perception. Finally, we constructed a mediation model with the emotional motivation direction or emotional motivation intensity as independent variables, attention control and attention bias as mediating variables, and time perception as dependent variable. The results showed that (1) Approach-motivation emotion underestimated the duration, and withdrawal-motivation emotion overestimated the duration. Meanwhile, there was an overestimation of duration for the high intensity withdrawal-motivation emotion, as opposed to low intensity. (2) Attention disengagement and attention control played multiple mediating roles in the influence of the direction of emotional motivation on time perception at 700 ms, 1700 ms, and 2700 ms. Specifically, compared with withdrawal-motivation emotion, approach- motivation emotion inhibited the level of attention control and showed more intensity in attention disengagement difficulty, leading to an underestimation of the duration. (3) Attention alert mediated the influence of the intensity of emotional motivation on the time perception at 700ms. Specifically, compared with the low intensity, the high intensity of withdrawal-motivation emotion showed greater attention alert, which led to an overestimation of the duration. In conclusion, the results showed that the direction of emotional motivation determined the direction of time distortion, and the intensity of emotional motivation determined the degree of time distortion at 700ms. Meanwhile, it revealed the internal mechanism of the dimension of emotional motivation on time perception, refined the role of attention resources in time perception, and further enriched the attentional gate model. Specifically, adjusting attention bias and attention control is an important way to adjust the influence of emotion on time perception. Figures and Tables | References | Related Articles | Metrics

The influence of voluntary action and social distance on sense of agency: Evidence from behavioral and ERPs study ZHONG Yiping, NIU Nana, FAN Wei, REN Mengmeng, LI Mei 2023, 55 (12):  1932-1948.  doi: 10.3724/SP.J.1041.2023.01932 Abstract ( 1214 )   HTML ( 155 )   PDF (3586KB) ( 1621 )   Peer Review Comments Sense of agency refers to the subjective experience of controlling one’s actions and, through them, external events, which is the core element that makes individuals responsible for their behavior to foster social cohesion. Recent studies have revealed that people potentially experience reduced sense of agency for harming others by claiming that they were obeying orders. However, little is known about the cognitive neural mechanism behind the reduced sense of agency when individuals are forced to inflict physical harm on others. We adopted a temporal estimation task to investigate the internal mechanism of voluntary action on the sense of agency and the moderating effect of social distance, as measured by event-related potentials (ERPs). In Experiment 1, participants were asked to trade monetary gains for themselves off against painful electric stimuli experienced by friends or strangers, subjectively estimated the perceptual temporal interval between keypress actions (i.e., free, or coercive actions) and consequent neutral outcomes, and rated the feeling of control and responsibility. Experiment 2 further investigated the cognitive neurobiological mechanisms of the interaction between voluntary action and social distance on the sense of agency using event-related potential (ERP) technology and attempted to examine the robustness of explicit sense of agency. Experiment 1 found that under the coercive condition, the time interval estimation for harming friends was shorter than for harming strangers, indicating a stronger implicit sense of agency. Regarding the explicit sense of agency, our study only found that participants in the free condition reported higher feeling of control and responsibility compared to those in the coercive condition. In Experiment 2, these results indicated that when participants obeyed commands to harm friends, the P3 was larger than when they obeyed commands to harm strangers. More importantly, the N1 was more negative in response to the auditory tones when participants obeyed commands to harm friends than when they obeyed commands to harm strangers. However, regarding the explicit sense of agency, our study only found that participants in the free condition reported higher feeling of control and responsibility than those in the coercive condition, which were not influenced by the social distance. Additionally, there was a significant correlation between the ratings of feeling of control and the decision- induced N2. These results indicate that social distance moderates the implicit sense of agency in the face of serious unethical outcomes, while participants’ feeling of control and responsibility were not affected by social distance due to self−serving bias. When obeying orders, individuals consciously exhibit moral disengagement. The present study has demonstrated that implicit and explicit sense of agency have different processing mechanisms, which broadens the previous insight into understanding the sense of agency. We discuss the implications of utilizing free choice and closing the social distance with others as significant strategies for those experiencing the abnormal sense of agency.

The effect of foreign language speaking anxiety on the quality of verbal interaction: A fNIRS-based hyperscanning study XU Chuyan, ZHU Lin, WANG Yunping, WANG Ruibing, LIU Conghui 2023, 55 (12):  1949-1965.  doi: 10.3724/SP.J.1041.2023.01949 Abstract ( 1056 )   HTML ( 117 )   PDF (2324KB) ( 1543 )   Peer Review Comments Foreign language speaking anxiety is one of the important factors affecting foreign language communication. Fear of negative evaluation is the key factor that induces foreign language speaking anxiety. Many studies have found that foreign language speaking anxiety can negatively affect the quality of verbal interaction through questionnaires and behavioral methods. Yet, few have investigated the brain mechanism of such influence. Therefore, we set up real English communication scene and used fNIRS (functional near-infrared spectroscopy) hyperscanning technique to further investigate relative brain mechanism. A total of 126 Chinese college students were recruited for two experiments. Participants were randomly paired (participant 1 and participant 2) and were asked to finish two storytelling tasks (English vs. Chinese) in turn in both experiments, with fNIRS recording their brain activities simultaneously. Specifically, 24 sequentially numbered pictures formed a complete story, participant 1 received pictures with odd numbers, and participants 2 received pictures with even numbers. During the task, one participant would tell the story of the current round, while the other need to listen carefully, and then both of them would complete the foreign language speaking anxiety scale and continued the story. The turn-taking process went on till the end of the story. The interaction quality was evaluated by two experimenter assistants on a seven-point Likert scale. In Experiment 2, participants were informed in advance that they will be evaluated after the task. This is the only difference between the two experiments, which aimed to rise participants’ fear of negative evaluation. Through this process, we intended to explore the effect of external evaluation on the degree of foreign language anxiety on behavior and neural levels. Two experiments obtained consistent results: (1) the participants had significant foreign language speaking anxiety in the English task (compared to Chinese), and their verbal interaction quality was also lower; (2) it was found that the Interpersonal Neural Synchronization (INS) of the left supramarginal gyrus and the left middle temporal gyrus was significantly weakened in each pair of participants in the English task. And weakened INS was also found in the left frontal pole; (3) in the English task, the INS of the left supramarginal gyrus was significantly negatively correlated with foreign language speaking anxiety, and significantly positively correlated with the self-rated verbal interaction quality. Foreign language speaking anxiety affected the quality of verbal interaction through a partial mediating effect of the INS of the left supramarginal gyrus; (4) external evaluation caused higher anxiety but didn’t influence the interaction quality. The above consistent results also show that even with the addition of an evaluation component, the effects of foreign language speaking anxiety on verbal interaction quality on behavioral indicators and INS remain unchanged. The results of this study suggests that foreign language speaking anxiety negatively affected the INS of brain regions involved in language and theory of mind. Our findings provide evidence of neural synchronization for understanding foreign language anxiety and verbal interaction and provide a theoretical basis for relieving foreign language speaking anxiety and improving foreign language communication quality.

Pain avoidance and effective connectivity between dlPFC and insula in suicide attempters with major depressive disorder HAO Ziyu, LI Huanhuan, LIN Yixuan 2023, 55 (12):  1966-1978.  doi: 10.3724/SP.J.1041.2023.01966 Abstract ( 1269 )   HTML ( 72 )   PDF (4294KB) ( 2344 )   Peer Review Comments Previous research has established pain avoidance as a critical and stable variable for identifying suicide attempts across samples. However, the neural mechanisms underlying pain avoidance and its relationship to suicide attempts remain unclear. Additionally, most previous research on the brain mechanisms of suicide has focused on single brain regions or circuits, neglecting the principle that the brain is organized into networks. Psychological pain is a complex, negative emotional experience that involves cognitive appraisal, psychosomatic responses, and motivational tendencies. Therefore, the brain mechanisms underlying psychological pain mainly involve impairments in pain processing, motivation, and decision-making circuits. Therefore, a more comprehensive approach is necessary to explore the neural mechanisms underlying psychological pain and its relationship with suicide attempts. The “pain matrix” is a functional brain network that plays an important role in pain processing. The medial pathway of the pain matrix is responsible for processing affective pain information and is considered the neural basis of psychological pain. The three-dimensional psychological pain model divides psychological pain into cognitive, affective, and motivational components. The medial pathway of the pain matrix is responsible for processing the affective components of psychological pain. Pain arousal, as a cognitive component, represents an individual's cognitive appraisal of painful past situations based on the recollection of past negative events and is closely related to the function of the hippocampus. Pain avoidance, as a motivational component, is closely related to the functions of brain regions involved in cognitive control, with the dlPFC being the core node for top-down cognitive control. Therefore, a combination of the medial pathway, dlPFC, and the hippocampus, defined as a “pain processing network”, can be used to explore the neural mechanisms of psychological pain and its relation to suicide attempts. Previous studies have linked neural mechanisms to the pathophysiology of suicide, based on brain region-specific functional and structural alterations. However, owing to the lack of directional analyses of multiregional connectivity, little is known about the top-down or bottom-up interaction patterns of the crucial brain regions mentioned above during pain processing in suicide. Therefore, this study aims to explore directional interaction patterns of multiple brain regions in the “pain processing network” and their relationships to pain avoidance, painful feelings, and suicide attempts. This may shed new light on the suicidal brain from a psychological pain-processing perspective. A total of 35 healthy controls (HC), 25 MDD patients with a history of suicide attempts (MDD-SA), and 48 MDD patients without such a history (MDD-NSA) participated voluntarily in this study. All participants completed measures of interested questionnaires and underwent resting-state functional magnetic resonance imaging. Granger causal analysis (GCA) was used to explore the effective connectivity patterns of brain regions in the pain-processing network. Behavioral results showed that the total TDPPS scores, pain arousal, painful feelings, pain avoidance subscale, BDI, and BSI were significantly higher in the MDD-SA group than in the MDD-NSA and HC groups. Importantly, the MDD-SA group showed weaker top-down effective connectivity from the right dlPFC to the right insula and stronger effective connectivity from the right lateral OFC to the left hippocampus and the right hippocampus to the right thalamus than the other two groups. Interestingly, the MDD-SA group showed stronger parallel effective connectivity from the left amygdala to the right amygdala than the MDD-NSA and HC groups. The MDD-NSA group showed weaker bottom-up effective connectivity from the left insula to the right dlPFC and from the left amygdala to the left dlPFC than did the other two groups. Notably, blunted effective connectivity from the right dlPFC to the right insula was negatively correlated with pain avoidance scores, suicidal ideation at the worst time point, and the number of suicide attempts. Weaker effective connectivity from the insula to the right dlPFC and from the left amygdala to the left dlPFC negatively correlated with the BDI score. As a pilot study focused on the directionally interactive patterns of the pain-processing network in suicide attempters, the results suggest that reduced top-down connectivity from the dlPFC to the insula plays a crucial role in the shared neural mechanisms underlying pain avoidance and suicide attempts. This blunting of top-down effective connectivity reflects the difficulty of suicide attempters in achieving effective cognitive control and adaptive behaviors in response to intense negative emotions. Consequently, the individual chooses to commit suicide, a non-adaptive behavior driven by powerful pain avoidance motivations. In contrast, the MDD-NSA group exhibited blunted bottom-up connectivity, which is distinguished from the connectivity pattern of the pain-processing network in the MDD-SA group. Therefore, this study provided neuroimaging evidence for the superiority of pain avoidance over depression in identifying suicide attempts.

The relationship between social exclusion and aggression: A meta-analysis JIN Juanjuan, SHAO Lei, HUANG Xiaoxiao, ZHANG Yali, YU Guoliang 2023, 55 (12):  1979-1996.  doi: 10.3724/SP.J.1041.2023.01979 Abstract ( 2053 )   HTML ( 197 )   PDF (919KB) ( 2953 )   Peer Review Comments Numerous studies have discussed the inducing factors of aggression, among which social exclusion has been widely concerned as a strong predictor. However, the studies about the association between social exclusion and aggression have shown mixed results. Theoretically, there are two main arguments about the relationship between social exclusion and aggression. The general aggression model suggests that social exclusion triggers negative emotions, hostile cognition, or a high level of physiological arousal, which leads to aggression.While the emotional numbness hypothesis argued that social exclusion causes individuals to be a state of physiological or emotional numbness, which avoids the occurrence of aggressive behaviour. Empirically, the effect sizes of this relationship reported in the existing literature were far from consistent, with r values ranging from -0.02 to 0.74. Therefore, this meta-analysis was conducted to clarify the strength of the relationship between social exclusion and aggression and reveal possible moderators. Through literature retrieval, 92 studies (99 independent effect sizes, a total of 65564 subjects) met the inclusion criteria were selected. A random-effects model was selected to conduct the meta-analysis in Comprehensive Meta-Analysis 3.3 software, aiming at testing our hypotheses. The results of heterogeneity test illustrated that there was significant heterogeneity among 99 independent effects, indicating that the random effect model was suitable for subsequent meta-analysis. Based on the funnel chart and Egger’s regression test of intercept, no significant publication bias was found. The main effect analysis indicated a significant positive correlation between social exclusion and aggression (r = 0.38, 95% CI [0.34, 0.41]); The moderation analyses revealed that the relationship between social exclusion and aggression was moderated by age, research methods, aggression types (reactive aggression vs. proactive aggression), social exclusion and aggression measurement tools, and research design (cross-sectional study vs. longitudinal study), but not by individualism index and gender. The results of this meta-analysis can clarify the controversy of the correlation between social exclusion and aggression, indicating that excluded individuals are often accompanied by the increase of aggression level. Future research are encouraged to strengthen the prevention and intervention of aggressive behavior caused by social exclusion among low-age groups, especially preschool children and primary school students.

Opportunity (in)equity affects outcome evaluation at an early cognitive stage YOU Tingting, ZHANG Liping, QI Guomei, LONG Changquan 2023, 55 (12):  1997-2012.  doi: 10.3724/SP.J.1041.2023.01997 Abstract ( 704 )   HTML ( 62 )   PDF (2327KB) ( 756 )   Peer Review Comments Opportunity equity is highly desired in human society. Previous studies have shown that opportunity (in)equity influences the evaluation of subsequent outcomes. However, it is unclear whether this influence occurs only at an early cognitive stage or extends to a late cognitive stage as well. Based on the notion that “people seem to be more committed to outcome equity than opportunity equity,” we hypothesized that opportunity (in)equity would affect outcome evaluation at an early stage in the cognitive process, but not at a late stage. Additionally, we indicate how limitations in the experimental design and data analysis of previous studies may have affected their conclusions. To examine the cognitive stage at which opportunity (in)equity influences outcome evaluations in a competitive social context, we recruited 31 college students (19 females, 19.52 ± 1.46 years) to participate in a competitive two-person choice game with their opponents. To account for the difference between subjective and objective predictions and the effect of varied choice numbers, we designed the game so that the participants had four cards in all trials. In contrast, their opponents randomly received two, four, or six cards in each trial, creating three opportunity conditions: advantageous opportunity inequity (AI), opportunity equity (OE), and disadvantageous opportunity inequity (DI). Both players selected only one card from the available options to compare their outcomes, which could result in a win, draw, or loss. Similar to previous studies, we recorded and analyzed event-related potential responses to actual outcomes, focusing on feedback-related negativity (FRN) and P300. We performed principal component analysis (PCA) to disentangle the overlap of FRN and P300. The analysis of behavioral results of our study demonstrated a significant interaction between opportunities and outcomes in relation to subjective pleasantness rating scores, indicating that opportunity (in)equity indeed influenced outcome evaluation. Furthermore, we found a significant interaction between opportunities and outcomes for both the original and PCA-FRN amplitudes, indicating that opportunity (in)equity affected outcome evaluation at an early cognitive stage. Specifically, when participants experienced a win, there was no significant difference in the original and PCA-FRN amplitudes among the three opportunity conditions. In contrast, when participants lost, AI and DI elicited more negative original and PCA-FRN amplitudes than OE, suggesting that participants were sensitive to opportunity equity in the context of loss. Moreover, we did not find a significant interaction between opportunities and outcomes, nor a main effect of opportunities, for either the original or PCA-P300 amplitudes. These results suggest that opportunity (in)equity did not have a significant influence on outcome evaluation at a late cognitive stage. Notably, draws elicited larger PCA-P300 amplitudes compared to wins and losses, indicating that participants were sensitive to outcome equity. In conclusion, our study demonstrates that opportunity (in)equity influences outcome evaluation at an early cognitive stage but not at a late stage. These findings provide valuable insights into the intricate temporal dynamics of the interaction between opportunity equity and actual outcomes, and contribute to fostering a more equitable society.

The double-edged sword effect of employee personal initiative behavior on coworker relationships: The moderating role of the employee warmth trait SONG Qi, REN Qiqi, CHEN Yang, REN Yingwei 2023, 55 (12):  2013-2034.  doi: 10.3724/SP.J.1041.2023.02013 Abstract ( 2711 )   HTML ( 271 )   PDF (849KB) ( 3857 )   Peer Review Comments Personal initiative behavior contributes to organizational success and helps employees navigate workplace uncertainty, and is therefore an essential research topic. However, most studies have focused on the influence of personal initiative behavior on leaders rather than coworkers. Moreover, the findings regarding the interpersonal effects of such behavior on coworkers are inconsistent. To address these issues, we take a contingency perspective that shifts the focus from a binary “good or bad for coworkers” logic to an understanding of the interpersonal benefits and risks of personal initiative behavior. Drawing on research stereotype traits, in this study we examine the moderating effect of the trait of employee warmth trait and explore the differential emotional and behavioral responses of coworkers toward employees with high or low warmth traits. We apply the approach-avoidance systems theory and hypothesize that warm and initiative-taking employees generate relational energy, leading to active facilitation behavior, whereas initiative-taking but non-warm employees may experience interpersonal disliking and subsequent ostracism behavior from coworkers. We conducted two studies to test our hypotheses. Study 1 involved a multi-source round-robin survey to test the proposed model. Each survey wave was separated by a three-week interval. At Time 1, team leaders assessed each team member’s personal initiative behavior and demographics. The team members then rated their own warmth trait and demographics. Three weeks later at Time 2, the team members evaluated relational energy and interpersonal disliking through a round-robin design. Finally, three weeks later at Time 3, they rated their active facilitation behavior and interpersonal ostracism behavior using a round-robin design. The dataset comprised 1, 164 dyads of 305 members in 65 teams. In Study 2, to enhance causal inference, a scenario-based experiment with a 2 (personal initiative behavior: high vs. low) × 2 (employee warmth trait: high vs. low) factorial design was conducted. The participants (280 full-time workers) were recruited from an online survey platform (Credamo) and randomly assigned to one of four scenarios. They reported their demographics, read the scenario, and provided responses to manipulation checks and questions regarding relational energy, interpersonal disliking, active facilitation behavior, and interpersonal ostracism behavior. In terms of data analysis, we considered the complex nested structure of the round-robin data in Study 1 and utilized a multilevel social relations modeling approach to test the research model. In Study 2, we used ANOVA and regression analyses to examine the causal relationships in our theoretical model. The empirical results supported our hypotheses, indicating that initiative-taking and warm employees were more likely to stimulate coworkers’ relational energy and increase their active facilitation behavior. Conversely, initiative-taking but non-warm employees were more likely to trigger interpersonal disliking among coworkers, subsequently leading to increased interpersonal ostracism behavior. This study has several theoretical implications. First, unlike studies that focus on singular effects, we explored the dual nature of the effects of personal initiative behavior on coworkers, thus providing a deeper understanding and a more comprehensive perspective. Second, by building on the literature on stereotype traits, we identified the employee warmth trait as a critical boundary that distinguishes the interpersonal benefits and risks of personal initiative behavior toward coworkers, thus reconciling other contradictory findings. Finally, by drawing on approach-avoidance systems theory, we revealed that relational energy and interpersonal disliking explain how and why coworkers have differential behavioral responses toward the personal initiative behavior exhibited by employees with high or low warmth traits.

Identity embarrassment and identity defense: The development of organizational identity of dispatched employees LI Luyun, JIA Liangding, ZHANG Yijie, WEI Liangyu 2023, 55 (12):  2035-2058.  doi: 10.3724/SP.J.1041.2023.02035 Abstract ( 1588 )   HTML ( 61 )   PDF (789KB) ( 1976 )   Peer Review Comments “Where do I belong?” This problem related to the identity of dispatched employees not only complicates their work and life but is key to a series of social problems, such as social injustice and mass unemployment. Although current research provides different perspectives for exploring the identity confusion of dispatched employees, there has been little analysis of the essential cause of this phenomenon: the complementary and dynamic characteristics of the dual organizational identity of dispatched employees. Therefore, little is known about how dispatched employees manage their complementary and dynamic dual organizational identity. What’s more, in the literature of multiple identity management or identity work, many scholars have explored how individuals manage two identities with independent, cross-cutting and nested relationships to achieve self-consistency or integrity. However, management strategies for two identities with a complementary relationship have not been discussed theoretically. This paper mainly adopts grounded theory to collect and analyze data. Through two-stage interviews (consisting of a survey and an in-depth interview), we collected data from 34 dispatched employees in different industries. The first author also collected the observational data during her internship at a labor dispatch company. The first, the third and the fourth author carried out the open, axial and selective step-by-step coding to construct a dynamic development model of the dual organizational identity of labor dispatched employees The results indicate three things: (1) In the comparison of expectations and experiences of dual organizational identity, there are three possible outcomes. “Match-match” promotes the realization of a dual organizational identity, “mismatch-mismatch” causes the rupture of a dual organizational identity, and “match- mismatch” is the main motivation for dynamic management of a dual organizational identity. (2) “Match- mismatch” poses a psychological dilemma called identity embarrassment for dispatched employees; they do not know where they belong. They adopt different identity defense strategies (depending on their attention and valence of interpretation) according to the relative importance of the dispatching unit and the employing unit in their identity. Three of these strategies—identity isolation, identity comparison and identity creation — alleviate identity embarrassment and promote the realization of the dual organizational identity. However, the identity rumination strategy further worsens identity embarrassment, leading to the rupture of the dual organizational identity. (3) “Match-match” promotes positive synergy based on social exchange, and “mismatch- mismatch” leads to negative synergy based on economic exchange. This paper enriches identity theory and organizational socialization in three areas. First, it expands the structural relationship between the two identities by introducing the complementary relationship contained in the dual organizational identity of dispatched employees, which is different from the independent, cross-cutting and nested relationships examined in previous studies. Second, the paper summarizes and refines the concepts of identity embarrassment and identity defense to explain the new identity problem and the identity management strategies adopted by the complementary and dynamic dual organizational identity. Third, the paper introduces the interaction between dual organizational identity and a complementary relationship of those identities, interpreting the positive synergy based on social exchange and negative synergy based on economic exchange. The conclusion of the study has important practical significance. It guides dispatch units and employing units to avoid the identity embarrassment of dispatched employees, and it promotes the realization of dual organizational identity to achieve win-win scenarios among the three parties of labor dispatching.
