    The influence of emotion on eating behavior
    ZHOU Aibao, XIE Pei, TIAN Zhe, PAN Chaochao
    Advances in Psychological Science    2021, 29 (11): 2013-2023.   DOI: 10.3724/SP.J.1042.2021.02013

    Eating behavior is not only regulated by the biological needs of people, but is also affected by emotional states, motivations, diseases, and more. There is a complex relationship between emotion and eating behavior. Consuming food can influence people's emotion. On the other hand, food attention, subjective appetite, and food intake can be influenced by emotion. Many studies have focused on emotional eating due to negative emotions. However, fewer studies focus on the effect that positive emotion has on eating behavior. The relationship between positive emotion and eating behavior is still controversial, as the relationship is underrepresented in research. The present study analyzed the eating behavior of clinical and non-clinical individuals who were affected by negative or positive emotions, and further explored the neurophysiology of eating behaviors and the various theories of the effect that emotions have on eating behaviors. The results showed that negative emotion increased attentional bias and intake for food and subjective appetite in the general population. This process was also affected by other factors; for example, modest women may restrict their food intake while experiencing negative emotions, so they may regain a sense of control which would offset the unpleasant feelings they were experiencing. In this study, there were two results regarding the effect that positive emotion has on eating behaviors. One theory was that positive emotions broaden momentary thought-action repertoires of people, which in turn builds their endurance. This leads us to believe that people resist food intake after positive emotion is induced. However, contrarily, positive emotion could increase hedonistic behavior in people, thus increasing food intake to maintain the experience of pleasure. Negative emotion increased both attention bias for food cues and subsequent intake in people with bulimia nervosa and binge eating disorders. Negative emotion causes decreased food intake in people suffering from anorexia nervosa. Positive emotion decreased binge eating in people with bulimia nervosa and binge eating disorders and relieved restrictive eating behaviors in people with anorexia nervosa. According to the reward theory, negative emotion can enhance reward sensitivity toward food. Following increased food intake, this process may show a synergy effect in the amygdala, insula, orbitofrontal cortex, striatum, and ventromedial prefrontal cortex. Negative emotion ruins the inhibitory control of individuals, meaning that they may begin to overeat, in association with the activation of the anterior cingulate cortex. According to self-related theory, negative emotion induces negative self-awareness. People can show attention bias due to immediate environmental stimulus, as overeating is meant to help people escape from their own negative self-awareness. Placing their attention on binge eating allows people with bulimia or other binge eating disorders to avoid dealing with information or environmental stimulus that may be hurtful. From the perspective of social culture, most eating behaviors with positive emotion have some special or celebratory meaning which increases the hedonic-oriented eating behavior of the individual. In general, the association between emotion and eating behavior has a certain regularity to follow. In the study, during a negative emotion, an individual’s eating behavior manifested in an extreme, unhealthy pattern, whether that meant an increased or decreased food intake. This study found a direct association between emotion and eating behavior; However, social culture, symbolism and connotation of certain foods, and an individual’s default eating styles (disinhibited and restrained eating) should be considered alongside the influence that emotion has on eating behaviors. In addition, most past studies self-reported food intake and subjective appetite as recorded by the individuals as the measurement. Future studies should adopt neuro-physiological methods to explore the effect of emotion on eating behavior and study a small set of neurons in the hypothalamus which regulates appetite, for example.

    The effect of attachment on the process of emotional regulation
    HUANG Yufei, SHI Pan, CHEN Xu
    Advances in Psychological Science    2022, 30 (1): 77-84.   DOI: 10.3724/SP.J.1042.2022.00077

    Previous studies based on attachment theory have proved the influence of attachment on emotion regulation. These influences can be manifested in many aspects, such as the choice of emotion regulation strategies, the effect of emotion regulation, and some cognitive processing related to emotion regulation. However, these studies ignore the complexity and diversity of emotion regulation as a process, and therefore cannot answer how attachment can affect emotion regulation. The extended process model divides emotion regulation into three stages, and clearly describes the process of emotion regulation and the relationship between various factors in the process. Combining the extended process model and the attachment theory to look back to previous studies is helpful to find out the relationship among these studies and expand new research directions. From the perspective of the extended process model, it can be found that there are individual differences related to attachment in all the three stages of emotional regulation. Specifically, in the recognition stage, the influence of attachment on emotion regulation is mainly reflected in the cognitive processing related to emotions. Both higher attachment anxiety and attachment avoidance are related to lower emotion recognition ability. At the same time, higher attachment avoidance is related to lower emotion recognition ability, and higher attachment anxiety is related to lower emotion regulation self-efficacy. In the selection stage, individuals with different attachment styles have different preferences for the choice of emotion regulation strategies. Most studies have found that individuals with secure attachment prefer to use highly adaptable and efficient strategies (such as cognitive reappraisal), and individuals with insecure attachment styles prefer to use strategies which are less adaptable and efficient(such as hypo-regulation or hyper-regulation). In the implementation stage, most studies have found that both attachment anxiety and attachment avoidance are significantly positively correlated with emotion regulation difficulties or disorders, but in some studies, high attachment avoidance individuals may not have problem with emotion regulation. In general, many factors are influenced by attachment in the process of emotion regulation, and the extended process model provides a theoretical framework for describing the sequence and causal relationship between these factors. However, there are still many key issues that have not yet been resolved. Future research can be expanded from the following aspects: The influence of attachment on emotional regulation should be explored while paying attention to the impact of environmental factors; New experimental paradigms need to be designed to confirm the continuity of the three stages and explore the reasons why attachment could affect emotional regulation. It is necessary to explore the influence of attachment on the emotion regulation flexibility. In addition, future intervention studies should design more targeted interventions to improve the emotion regulation of insecurely attached individuals.

    Psychological and behavioral effects of personal names in real world: Evidence and theories
    BAO Han-Wu-Shuang, CAI Hua-Jian
    Advances in Psychological Science    2021, 29 (6): 1067-1085.   DOI: 10.3724/SP.J.1042.2021.01067

    Personal names not only can influence others' impression and evaluation, but also may affect individuals' own psychology and behavior in real world. Over the past century, psychologists have conducted numerous empirical studies in the domains of decision making, achievement, health, and personality to examine the actual impacts of surnames or given names on individuals. Various dimensions of names (e.g., name uniqueness, name gender, name valence, and name warmth-competence) could, more or less, predict human psychology and behavior (e.g., career/life/economic decisions, career/academic achievements, physical/mental health, criminal behavior, personality traits, psychological needs, and facial characteristics). However, existing evidence is mixed, and current theories are far from adequate. Future studies should examine multiple dimensions of names, deal with methodological problems (e.g., replicability, causality, mechanisms, and cross-cultural generalizability), and try best to develop more systematic and inclusive theories to explain the psychological and behavioral effects of names.

    The influence of extrinsic and intrinsic motivation on memory in adolescents and the underlying neural mechanisms
    ZHANG Mingxia, LI Yuxin, LI Jin, LIU Xun
    Advances in Psychological Science    2023, 31 (1): 1-9.   DOI: 10.3724/SP.J.1042.2023.00001

    Motivation is the core of all behaviors. Motivation can be classified as the extrinsic and intrinsic motivation. The processing of the extrinsic and intrinsic motivation involves the reward, value, and control systems that would interact with the hippocampal memory system to facilitate memory performance. During adolescence, the brain develops rapidly, making it a critical period for memory development. Meanwhile, the subsystems of motivation develop unbalanced during adolescence (i.e., the reward system is sensible and the control system is immature), making it a special period for the motivation development. However, so far, the investigation of how extrinsic and intrinsic motivation impact teenage memory is on the start stage. There is a lack of systematic exploration and comparison of the behavioral rules and neural mechanisms of the extrinsic and intrinsic motivation’s impact on memory during adolescence. It remains unclear whether the rules and mechanisms of the extrinsic and intrinsic motivation’s impact on memory are common or specific and how the extrinsic and intrinsic motivation interacts with each other to affect memory during adolescence.

    As the monetary reward is easy to operate and quantify, previous research always used monetary reward to manipulate extrinsic motivation. In addition, intrinsic motivation is a hotspot in recent neuroscience research. Autonomy is the core concept of intrinsic motivation, which is often induced by self-determined choice. The current research will focus on monetary reward (extrinsic motivation) and self-determined choice (intrinsic motivation). We will integrate psychological and neuroscience methods and conduct a series of experiments to systematically reveal the impact of the extrinsic and intrinsic motivation on memory during adolescence on multiple levels (cognitive level, neural activity level and neural network level). Specifically, the current research will directly compare the mechanisms via which the extrinsic and intrinsic motivation affects memory and we will also examine how the extrinsic and intrinsic motivation interacts with each other to affect memory, so as to reveal the unique behavioral rules and neural mechanisms via which the two types of motivation (the extrinsic and intrinsic motivation) affect memory during adolescence. This research will greatly enrich the theory and improve the level of the field of motivation and memory. It has important theoretical significance for us to understand the nature of motivation, the underlying mechanisms of how motivation affects memory and the brain development during a very critical period in our life, the adolescence. It also has important practical significance for promoting adolescents’ motivation and learning.

    Prevalence of mental health problems among college students in mainland China from 2010 to 2020: A meta-analysis
    CHEN Yumeng, ZHANG Yali, YU Guoliang
    Advances in Psychological Science    2022, 30 (5): 991-1004.   DOI: 10.3724/SP.J.1042.2022.00991

    College students are a huge part and an important member of the young people. Their physical and mental health not only directly affects their own long-term development, but also has a significant influence on the future of the nation. Therefore, the mental health of college students has become the focus of families, schools and even the whole society. In recent years, some studies have conducted meta-analyses on the prevalence of a certain mental health problem (such as depression and sleep problem) among college students in China, but such studies cannot reflect the mental health status of college students comprehensively. And some of the previous studies cannot reflect the current status of contemporary college students’ mental health. Furthermore, the selection of moderator variables was not comprehensive enough to reveal the key factors affecting the prevalence. Therefore, we employed a meta-analysis in this study to estimate the prevalence of typical mental health problems among college students in mainland China from 2010 to 2020, and the moderating effects of publication year, measurement tools and detection standards, detection time, region, birthplace, only child or not were further analyzed. For the selection of indicators, mental health problems were divided into two categories: internalizing problems and externalizing problems. The indicators of internalizing problems include anxiety, depression, sleep problem, somatization, and suicidal ideation, while the indicators of externalizing problems include nonsuicidal self-injury and suicide attempt.
    Through the process of literature search and selection, 128 studies (136 effect sizes) of anxiety, 237 studies (244 effect sizes) of depression, 56 studies (58 effect sizes) of sleep problem, 49 studies (49 effect sizes) of somatization, 31 studies (31 effect sizes) of nonsuicidal self-injury, 51 studies (51 effect sizes) of suicide ideation, and 8 studies (8 effect sizes) of suicide attempt were included in this study. Homogeneity test indicated that random effects model was appropriate for the meta-analysis. The p-curve analysis illustrated no publication bias. Ultimately, the results of the main effect test showed that the prevalence rates of sleep problem, depression, nonsuicidal self-injury, anxiety, suicidal ideation, somatization, and suicide attempt were 23.5%, 20.8%, 16.2%, 13.7%, 10.8%, 4.5%, and 2.7%, respectively. The results indicate that internalizing problems, especially sleep problem and emotional problem, are more serious among Chinese college students compared to externalizing problems.
    The results of the moderating effect indicated that (1) The prevalence of anxiety, depression, sleep problem and suicide attempt among college students has increased significantly in the last decade, while the prevalence of self-harm has declined significantly; (2) The prevalence of anxiety, depression, sleep problem, and somatization varied significantly between measurement tools and detection standards, and the prevalence of suicidal ideation differed to a significant extent depending on the detection time. Therefore, the fluctuation of prevalence was accounted by measurement tools, detection standards and detection time. (3) There existed obvious regional differences in the prevalence of sleep problem and suicidal ideation, with the feature of the worst mental health among college students in western China and better mental health among college students in northeastern and central China. (4) The prevalence of mental health problems among demographical variables including gender, only child or not, and birthplace showed no significant difference, which indicated that gender, only child or not, urban or rural areas were not the critical factors influencing college students’ mental health.
    In summary, by employing the method of meta-analysis, this study is the first study to systematically investigate the prevalence of the typical mental health problems of college students in mainland China from 2010 to 2020. The results clarified the controversy over the inconsistent prevalence in previous studies and explored the main reasons for the inconsistent findings. Thus, this meta-analysis is conducive to promoting subsequent studies and educational practice.

    Nowadays, with the rapid development of the Internet, online communication has become increasingly popular and popular. However, due to the lack of nonverbal cues in face-to-face communication, it is difficult for people to detect the emotional state of each other, which hinders normal communication. Emoji, which compensate for nonverbal cues in online communication, have been introduced into cyberspace to compensate for the absence of gestures and facial attributes in online communication, and have been developing constantly. The development of Emojis has gone through Emoticon composed of ASCII characters, Emoji of pictographic icons and now emerging more vivid and interesting stickers. This paper will mainly comb, analyze and summarize the functions, influencing factors and interaction mechanisms of Emoji in network communication, as well as the current application of Emoji in different fields, and put forward the future research direction of Emoji based on the current research status of Emoji.
    At the beginning, Emoji is borrowed from Japanese animation symbols, and gradually developed into a widely used image symbol system. Since the creation of Emoji by Shigetaka Kurita in 1999, it has been enriched and developed continuously At present, Emoji has become a tool commonly used around the world to replace non-verbal cues such as body gestures and facial expressions in digital communication. In the process of continuous use in Internet communication, Emoji has been equipped with many functions, including expressing emotions, enhancing expression, changing tone, maintaining or enhancing interpersonal relationship, etc. At the same time, the use of Emoji is also affected by many factors, including age, gender, culture, context and platform. In addition, we also explore the interactive mechanism of Emoji in online communication from the perspective of symbol interaction theory, so as to clearly reveal the specific interaction process of people in online communication through Emoji.
    At present, with the continuous development and widespread use of Emoji, its application scope has been extended to many other fields besides Internet communication. In the field of sentiment analysis, Emoji has become an important object of sentiment analysis due to its rich emotions. In psychometrics, Emoji has been developed into a nonverbal tool for evaluating personality and depression which has the same reliability and validity as text items. In the field of commercial marketing, Emoji has begun to play a role in advertising marketing and attracting consumers, and can measure consumers' food-related emotions in the form of questionnaires. In the field of legal judgment, Emoji has gradually become a powerful evidence in judicial trials due to its widespread use. Through the above analysis and summary, we put forward the future research direction of Emoji from the following aspects: (1) explore the application and future development trend of Emoji in online communication; (2) study on the application of Emoji in other fields; (3) further explore the neurophysiological mechanism of Emoji; (4) discuss the positive effect of Emoji in online communication from the perspective of cognitive processing.

    Effect of parental marital conflict on child development and its mechanism
    WANG Xuesi, LI Jingya, WANG Meifang
    Advances in Psychological Science    2021, 29 (5): 875-884.   DOI: 10.3724/SP.J.1042.2021.00875

    Marital relationship is one of the core relationships in family. The conflict in marital relationship is recognized as a factor in accounting for adverse effect on child development. The primary objective of the current review was to provide a comprehensive overview of the effect of parental marital conflict on child development and its mechanism. Furthermore, crucial future direction in this field was proposed based on the existing studies.
    Parental marital conflict had been established as a risk factor for child cognitive and socioemotional development in both theoretical and empirical studies. Specifically, parental marital conflict may lead to poor executive functioning and academic achievement. Moreover, children who experienced parental marital conflict were more likely to show more problem behavior (i.e., internalizing and externalizing problem behavior; the effect on internalizing problem behavior was larger than that on externalizing problem behavior) and social maladjustment (e.g., poor parent-child, sibling, peer, teacher-student, and even adulthood intimate relationship). It should be noted that parental marital conflict had a short-term and long-term effect on children’s cognitive and socioemotional development, and the increasing parental marital conflict may have a more significant effect.
    Guided by process-oriented approach, researchers began to focus on how parental marital conflict affected child development. Children’s cognitive and emotional process and family process were described to clarify the pathways by which parental marital conflict influenced child development. As for children’s cognitive and emotional process, cognitive-contextual framework emphasized the crucial role of children’s cognitive appraisal toward parental marital conflict. Children who viewed parental marital conflict as threatening to themselves or the well-being of family, felt that they were responsible for the conflict, and/or had inadequate skills for successfully coping with the conflict were likely to experience maladjustment. Emotional security theory posited that parental marital conflict undermined children’s emotional security and further development. As for family process, according to family systems theory, parental marital conflict was often accompanied by negative emotion and behavior, which may spillover into parent-child interactions, resulting in ineffective parenting, disagreement over child-rearing, and parent-child triangulation. These negative interactions may carry detrimental consequences for children.
    Moreover, child and environmental factors may moderate the association between parental marital conflict and child development. Specifically, child age and gender may play a moderating role in this association, but the evidence was somewhat mixed. Guided by the biopsychosocial model, the autonomic nervous system functioning in children also served as a moderator of the association between parental marital conflict and child development. Previous studies shed light on the joint action of the two branches of the autonomic nervous system, the parasympathetic nervous system (PNS) and sympathetic nervous system (SNS), and revealed that opposing action of the PNS and SNS (i.e., coactivation and coinhibition) operated as a vulnerability factor for child development in the context of parental marital conflict, whereas reciprocal action of the PNS and SNS (i.e., reciprocal parasympathetic activation and reciprocal sympathetic activation) operated as a protective factor. As with child age and gender, the evidence for reciprocal parasympathetic activation was also mixed. In addition, the ecological systems theory emphasizes that environmental factors (e.g., family socioeconomic status, social support, and cultural values) may also moderate the effect of parental marital conflict on child development. A high level of family socioeconomic status and social support may buffer the negative effect of parental marital conflict on child development. However, culture value that emphasized family and social harmony may intensify the negative effect.
    Future studies should use individual-centered approaches to examine the effects of different types of parental marital conflict on child development in multiple aspects simultaneously and integrate the multi-mechanism of parental marital conflict on child development. Cross-cultural studies should be carried out to further examine the role of culture in the effect of marital conflict on child development. Additionally, future studies should further examine the cyclical bidirectional association between parental marital conflict and child development.

    Effects of mindfulness-based interventions on self-compassion: A meta-analysis
    SUN Tengwei, YAN Yuxian, JIN Yuchang, AN Junxiu
    Advances in Psychological Science    2021, 29 (10): 1808-1828.   DOI: 10.3724/SP.J.1042.2021.01808

    Both mindfulness and self-compassion have positive effects on mental health, and the relationship between them has always been the focus of researchers. And mindfulness and self-compassion are also closely related. Previous research has found that mindfulness can predict an individual's level of self-compassion, a component of which also includes mindfulness. However, different studies used the same two variables to measure, and the correlation coefficient between mindfulness and self-compassion was significantly different. Therefore, it is necessary to explore the reasons for the large correlation coefficient difference between mindfulness and self-compassion. In this study, meta-analysis method was adopted, combined with empirical research results from global research, to deeply explore the relationship between mindfulness-based interventions and self-compassion in different groups and different contrast ways, as well as the factors that affect the relationship between them.

    Through a comprehensive search of Chinese and English literature up to November 2020, a total of 65 literature were finally included in this meta-analysis, including 62 English literature and 3 Chinese literature, and 99 independent effects were obtained, with a total sample size of 8103. In addition, 22 articles were included in the literature using horizontal comparison, 42 articles using longitudinal comparison; 16 articles using follow-up comparison. This paper mainly used Pearson correlation coefficient r as the effect value, and the effect value of the literature was coded as an effect value for each independent sample. If a paper reported multiple independent samples at the same time, the effect value would be coded separately to generate multiple independent effect sizes. After testing the publication bias through funnel plot, Rosenthals Classic Fail-safe N test, and Egger's test, it is found that there was no publication bias. After the heterogeneous test, the article also has high heterogeneity, so the analysis after the random effect model is selected. Sensitivity analysis showed that the degree of heterogeneity was effectively reduced after using One-study removed to gradually delete the research with higher heterogeneity, but regardless of the degree of heterogeneity, the intervention based on mindfulness was positively correlated with self-sympathy. This study discussed the moderating effects of different contrast methods (horizontal comparison, longitudinal comparison, follow-up comparison), sample groups (students, health care related workers, social related workers), and measurement tools (SCS, SCS-SF) on the relationship between mindfulness and self-compassion. The subgroup test showed that the relationship between mindfulness-based intervention and self-compassion was influenced by the moderating effect of contrast style, but not by the sample group or measurement tool.

    The results showed that the mindfulness-based intervention had a significant positive correlation with self-compassion, and the mindfulness-based intervention had a positive impact on the level of self-compassion. The relationship between the mindfulness-based intervention and self-compassion was affected by the way of measurement comparison, but did not have a significant moderating relationship with the group and the measurement tool. The reason why there is such a big difference among many domestic and foreign studies is probably due to the difference of measurement methods and the difference caused by the in unity of measurement methods. Overall, in many experimental studies on the relationship between mindfulness and self-compassion, no matter which contrast method is used for measurement, the individual's level of self-compassion has increased after mindfulness-based intervention.

    The effects of prosocial spending on subjective well-being and its mechanism
    CUI Xinyue, LI Bin, HE Ruwan, ZHANG Shuying, LEI Li
    Advances in Psychological Science    2021, 29 (7): 1279-1290.   DOI: 10.3724/SP.J.1042.2021.01279

    While prosocial behavior has long been concerned by researchers, many recent studies have focused on prosocial spending. Prosocial spending refers to spending money on others in the form of gifts or charitable donations. Compared with other prosocial behaviors, spending money on others is less time needed and more popular in the online environment. Prosocial spending not only benefits the recipient but also exerts a positive effect on the giver’s subjective well-being. We would discuss some important aspects which have been explored in the relationship between prosocial spending and subjective well-being. First of all, the effect of prosocial spending on subjective well-being depends on the type of recipient (individual vs. organization or society at large). Secondly, this effect has been proved to cultural universality and cultural persistence. Prosocial spending is relatively immune to the effects of hedonic adaptation, because people’s daily life affords numerous opportunities for they to spend money on others, which potentially providing frequent small doses of joy.

    Moreover, the mechanism underlying this effect could be explained by several theories, which include self-determination theory, social norm theory, evolution theory and social exchange theory. According to self-determination theory, prosocial spending promotes people’s subjective well-being through satisfied with the fundamental human needs for competence, relatedness, and autonomy. Specifically, prosocial spending provides an opportunity for people to make a meaningful impact, which is potentially satisfying the human need for competence. It can also enhance people’s feelings of social connection, therefore satisfying the human need for relatedness. And people would derive more happiness from prosocial spending when they have an autonomous motivation for helping. According to social norm theory, most others would approve of a person's conduct when people compliance with social norms. Because prosocial spending is driven by a desire to adhere to social norms, then individuals can maintain a positive self-concept and improve their own happiness levels by this way. According to evolutionary theory, people tend to be happier when their prosocial spending on relatives rather than unrelated individuals. At the same time, prosocial spending can also be explained by the model of reciprocal altruism. Spending money to benefit others can leave a good impression, such that people may improve their social status and reputation, and thereby enhance individual subjective well-being. According to the social exchange theory, when individuals spending money on others, they make a cost-benefit analysis based on their own values. And the giver can get happiness as emotional rewards after the prosocial spending even they don’t get a material benefit from the recipient.

    Additionally, both internal and external factors influence the relationship between prosocial spending and subjective well-being. External factors such as culture would make an impact on them, because define of subjective well-being and prosocial behavior is different between differetial cultures. And the goals of prosocial spending would also influence this effect. People would benefit more postive affect from specifical goal other than fuzzy goal in their prosocial spending. Internal factors include individual motivations and their understanding of happiness. When people doing the prosocial spending is driven by their own internal motivation (vs. Internal motivation), it is more likely to promote the subjective well-being.

    In general, this research underscores the value of prosocial spending is not only helping others, but also is improving their own subjective well-being. This finding can change the individual's stereotypes of spending that is loss, and it can even motivate people to actively participate in more prosocial activities, thus to make great contributions to people’s happy life and the construction of a harmonious society. Future studies should focus on examining the boundary conditions of the effect, exploring the long-term positive effects of prosocial spending, and improving the ecological validity of research on prosocial spending.

    Less is more: A theoretical interpretation of minimalism in consumption
    CHEN Siyun, WEI Haiying, XIONG Jiwei, RAN Yaxuan
    Advances in Psychological Science    2021, 29 (11): 2043-2061.   DOI: 10.3724/SP.J.1042.2021.02043
    Abstract5856)   HTML352)    PDF(pc) (859KB)(4035)       Save

    Minimalism refers to a lifestyle that seeks satisfaction in a non-material world by reducing consumption. Given the increasing popularity of minimalistic consumption (i.e., voluntary simplicity), it is necessary to understand minimalism more comprehensively. First, we provide a categorization scheme related voluntary simplicity, including its conception, dimensions, and measurements. Characterized by a minimal, simple, and responsible lifestyle, minimalism can be defined as the degree to which consumers select a lifestyle to minimalize their consumption and to take control of their life. The practice of simplified living typically entails minimizing possessions, consuming less, and valuing personal growth.
    Then, factors that influence minimalistic consumption are presented. The reasons for individuals to adopt simplifying behaviors are manifold. That is, motivations for engaging minimalistic consumption are multifaceted and complicated, including both internal (i.e., personal, financial, lifestyle) and external (i.e., economic, social, environmental) motivations. In addition to consumers who curtail their consumption due to financial restraints, there are consumers who consciously consume, although they are financially well off. The rejection of the concept that one’s success is determined by his/her material goods (i.e., materialism) has prompted interest in minimalistic consumption. In addition, some simplifiers (i.e., minimalistic consumers) are driven by motives of environmental sustainability. That is, when consumers give greater consideration to the natural environment and ecological system, they may engage in voluntary simplicity to live both well and sustainably. Furthermore, people can lead an independent and self-determined life through minimalistic consumption; therefore, a desire to achieve an autonomous life is an important antecedent of minimalistic consumption. Moreover, philosophical motivation (i.e., religious belief) is another factor driving minimalism in consumption.
    Moving forward, the potential impacts of minimalistic behavior are shown. Minimalism has a positive influence on individual, societal and environmental wellbeing. Adopting low consumption helps expand mental space, resulting in a feeling of lightness, relaxation, and clarity. A minimalistic lifestyle facilitates individuals’ positive emotions while reducing their negative emotions such as depression. Consumers can also reduce their dependence on the market offerings by curtailing the overall consumption, in search of a simpler but happier life. Additionally, minimalistic practices offer several wellbeing benefits such as meaning and happiness. In addition, a minimalistic lifestyle can improve harmony in communities, as it can help build more connections with others in society. By sharing skills, donating to charities or giving back to the community, simplifiers can experience a sense of community and closeness to others, thus enhancing communal well-being. More importantly, most literature notes that this lifestyle is positively associated with environmental and ecological wellbeing. With a strong ecological awareness, consumers tend to protect the environment through a variety of practices, such as decreasing carbon emissions, avoiding excess packaging, and preserving resources and habitats. Collectively, we categorize antecedents of minimalistic consumption into four types (i.e., demographic, psychological, situational, religious factors). We also summarize the effects of minimalistic consumption in the previous research, such as enhancing happiness and sense of meaning.
    In order to understand voluntary simplicity, four theories (i.e., theory of basic values, self-determination theory; hierarchical theory of needs; self-regulation theory) were introduced. By combining these theories, we shed a novel light on understanding the forming process of minimalistic consumption. Specifically, in self-observation stages, individuals generate self-directed values. Based on these values, consumers make judgments whether their needs are satisfied. Lastly, in the self-reaction phase, consumers adopt the results of these judgments, and they evaluate achieve autonomy, competence and relevance from the self-determination theory. Given the important role of minimalistic consumption in the contemporary marketplace, it is essential for both marketers and scholars to know more details in simplifying practices. Several directions (e.g., developing valid measurements, taking cultural differences into account, identifying boundary conditions) for future research are discussed.

    In modern affluent societies, where palatable foods are readily available, resisting the food craving brought by tempting food clues and keeping restrained eating to maintain a healthy body weight has become one of the challenging propositions. In recent years, in order to identify the reasons for the success of dieting, domestic scholars have created a Chinese Food Image Database to investigate the neuro-cognitive mechanism of restrained eating, and examine the differences of brain mechanism between successful and unsuccessful restrained eaters. In particular, based on the neural correlates of food craving, researches on general food craving and spicy food craving with Chinese characteristics has been carried out. Exploring the neuro-cognitive mechanisms of restrained eating and food craving can not only promote the theoretical developments of eating behavior research, but also provide important support for health interventions such as obesity and eating disorders.

    Cognitive mechanism and neural basis of shyness
    LI Liang, LI Hong
    Advances in Psychological Science    2022, 30 (5): 1038-1049.   DOI: 10.3724/SP.J.1042.2022.01038

    Shyness refers to individuals’ inhibition in a social situation; it can be an obstacle to participation in social interactions. In recent years, there has been an increase in cognitive neuroscience research on shyness. Within the frameworks of the metacognition model of shyness, the social fitness model of shyness, the lateralized brain-body emotion model of shyness, and the differential susceptibility to environmental influences model of shyness, researchers have explored the brain function differences, related brain networks, and cognitive processes underlying shyness. However, current cognitive neuroscience research on shyness is still in its infancy. For example: (1) researchers have mainly defined shyness from the perspective of personality; (2) the theoretical models of shyness are far from perfect; (3) the results of relevant empirical research have been unsystematic and inconsistent.
    Based on the above, this study proposes a psychological development model of shyness, which includes the following four perspectives. (1) Timeline of human evolution: the interaction of genetic factors (susceptibility genes), the internal environment (brain), and the external environment (such as school, family, and culture) affects the development of shyness. In the process of human evolution, human beings and their offspring showed different reactivity to the external environment, resulting in the survival of the fittest. The result of this process is that some individuals carry shyness susceptibility genes, which will not only determine their internal environment (brain) but also be affected by their internal environment (brain) and shape their metacognition and cognitive processes under the influences of school, family, culture, and other aspects of the external environment. The brain environment responsible for shyness is an expression of the interaction between the cognitive control system (centered in the prefrontal lobe) and the emotional system (centered in the amygdala-hypothalamus). Specifically, the cognitive bias/emotional arousal of shy individuals is the result of an imbalance in the regulation of the limbic system (centered in the amygdala-hypothalamus) by the prefrontal cortex. In other words, when facing an external stimulus, the amygdala of highly shy individuals is highly activated, which results in a highly emotional interpretation of low-level external stimuli, which is then projected to a wide range of brain regions including the hypothalamus. The hypothalamus then activates emotional expression by regulating the autonomic nervous system. In this process, the prefrontal cortex plays a top-down regulatory role, in which the strong activation of the right prefrontal lobe and the weak activation of the left prefrontal lobe of highly shy individuals leads to the disinhibition of the activated amygdala, hypothalamus, and other brain regions. Thus, the individual’s ability to regulate their emotions becomes weak and they cannot behave in an adaptive manner. The aspects of the internal environment that influence shyness include the differentiation of brain structure, the lateralization of brain function, and the uniqueness of the brain network. Moreover, in specific brain cognitive processing tasks, individuals with different levels of shyness have significant differences in the activity of different frequency bands and different cognitive components. (2) Timeline of individual development: the critical period of individual development affects the development of shyness. Specifically, the key development period of shyness is largely affected by the development of self-consciousness. With the maturity of self-consciousness, the externalized performance of individuals with different levels of shyness can be clearly distinguished. (3) Social situations: in specific social situations, the metacognition of shy individuals guides their cognitive processes, making them show differences in their physical, emotional, and behavioral performance. At the same time, different kinds of social situations will awaken individuals’ shyness to different degrees.
    Future research can be carried out from the following perspectives based on the psychological development model: (1) in terms of personality, clarify whether shyness describes a small number of extreme individuals or is instead a dimension that can sort the whole population; (2) explore the internal process of the emotional experience of shyness; (3) develop experimental research paradigms of shyness; (4) with the help of new brain technology, deeply explore the brain mechanism of shyness; (5) verify, expand, and improve the theoretical model related to shyness in the field of cognitive neuroscience.

    Prevalence of mental health problems among primary school students in Chinese mainland from 2010 to 2010:A meta-analysis
    HUANG Xiaoxiao, ZHANG Yali, YU Guoliang
    Advances in Psychological Science    2022, 30 (5): 953-964.   DOI: 10.3724/SP.J.1042.2022.00953
    Abstract2435)   HTML175)    PDF(pc) (574KB)(3904)       Save

    In recent years, the age of mental health problems shows a descending trend. Primary school students, as a special group in the critical stage of personal growth, are experiencing increased mental health problems that has caught wide attention from society. If the mental health problems of primary school students are not screened, prevented, and intervened in time, they may develop into lifelong mental diseases, which are difficult to redress and treat. Hence, as the basic premise of improving mental health, it is particularly important to find out the prevalence of pupils' mental health problems, so as to understand their real mental health status, and make targeted detection and intervention in the future.
    However, the prevalence of primary school students' mental health problems described in literature shows inconsistent results, and the prevalence varied greatly, which has brought confusion to mental health educators and workers. Although some researchers tried to use meta-analysis to quantitatively integrate the existing research findings, avoid the influence of biased samples, demographic characteristics, and other factors, and attempt to explore the detection rate of primary school students’ mental health problems objectively and accurately, there were still some deficiencies. Firstly, it only revealed the prevalence of some mental health problems, and did not cover more comprehensive mental health problems. Secondly, it did not specifically analyze the mental health problems in recent 10 years. Finally, the inclusion and discussion of regulatory variables were not specific enough. Therefore, based on the research results in recent 10 years, it is necessary to integrate the prevalence of primary school students' mental health problems and explore its influencing factors by using meta-analysis method.
    In order to clarify the debate on the different prevalence of primary school students' mental health problems, we analyzed and estimated the detection rate of primary school students' mental health problems in mainland China from 2010 to 2020 and investigated its moderation effects. The meta-analysis technology was used to retrieve the research on anxiety, depression, somatization, withdrawal, sleep problems, aggressive and discipline behaviors in Chinese National Knowledge Infrastructure database and Web of Science core collection database from 2010 to 2020. Finally, a total of 101 research and 289396 primary school students were obtained: 9 articles about anxiety, 34 articles about depression, 12 articles about somatization, 10 articles about withdrawal, 11 articles about sleep problems, 13 articles about aggressive behavior, and 12 articles about disciplinary behavior. The software Comprehensive Meta-Analysis Version 3.3 and the random effect model was selected for analysis.The results showed that (1) The prevalence of mental health problems in primary school students from high to low were sleep problems (25.2%, 95%CI = [0.16, 0.37]), depression (14.6%, 95%CI = [0.12, 0.18]), anxiety (12.3%, 95%CI = [0.06, 0.23]), aggressive behavior (4.1%, 95%CI = [0.02, 0.10]), withdrawal (3.8%, 95%CI = [0.02, 0.06]), disciplinary behavior (3.7%, 95%CI = [0.02, 0.07]) and somatization (3.6%, 95%CI = [0.02, 0.07]); (2) Measurement tools, measurement standards and detection period were the key factors causing the fluctuation of prevalence of mental health problems among primary school students in China. Generally speaking, the overall mental health status of primary school students in China is acceptable except that the prevalence of sleep problems, depression and anxiety are high. In the future, we should develop mental health assessment tools and detection standards suitable for Chinese primary school students to provide support for the prevention and accurate intervention of mental health problems.

    Tall trees catch much wind: Fear of positive evaluation in social anxiety
    YE Youcai, LIN Ronmao, YAN Youwei
    Advances in Psychological Science    2021, 29 (6): 1056-1066.   DOI: 10.3724/SP.J.1042.2021.01056

    Fear of positive evaluation (FPE) is a key trait to effectively distinguish social anxiety from depressive symptom. It is defined as an emotional response involving fear of and distress about positive evaluation from others. Its role of social anxiety manifests in that it leads individuals with social anxiety to deny the positive evaluation, avoid attention from others, and be in negative mood by themselves. Furthermore, it aggravates individual's cognitive bias, and suppress positive emotions through Disqualification of Positive Social Outcomes (DPSO) and the Interpretation Bias (IB), thereby maintaining and exacerbating the symptoms relating to social anxiety. Future research not only should more consider the application of FPE in education and consultation, but also should pay more attention to its special characters in Chinese modest culture background.

    Moral injury: A review from the perspective of psychology
    AI Pan, DAI Yan
    Advances in Psychological Science    2022, 30 (1): 168-178.   DOI: 10.3724/SP.J.1042.2022.00168

    Moral injury refers to the long-lasting psychological, biological, spiritual, behavioral and social impact on an individual after the exposure to morally injurious events, which entail “perpetrating, failing to prevent, bearing witness to, or learning about acts that transgress deeply held moral beliefs and expectations” (Litz et al., 2009). Since Litz et al. (2009) redefined this concept from the perspective of psychology, moral injury has attracted extensive attention in the fields of psychology, ethics, psychiatry, and sociology. The present article reviews and summarizes the concept, relevant mechanisms, measurements, and interventions of moral injury and offer recommendations for future research. We first review the background of moral injury. Moral injury can be traced back to survivor guilt, which has long been regarded as one of the symptoms of post-traumatic stress disorder. However, Litz et al.(2009) pointed out that moral injury and post-traumatic stress disorder are two different concepts, and Shay(2014) listed the five differences between moral injury and post-traumatic stress disorder in detail. Next, we review the mechanisms of moral injury. Under the influence of individual and social factors, potentially morally injurious events that severely violate an individual's moral code can lead to cognitive dissonance and intrapsychic conflict, and eventually produce lasting shame, guilt, and anxiety. In addition, different types of potentially morally injurious events may lead to different types of moral injury, but the specific mechanism is still unclear. Self-oriented events (e.g., committing a crime, failing to prevent a crime, etc.) are more likely to result in negative internal emotions and cognitions (e.g., guilt, shame, inability to forgive oneself), whereas other-oriented events (e.g., witnessing an act of violence, betrayal by a trusted person) are more likely to lead to negative external emotions and cognitions (e.g., anger, loss of trust, inability to forgive).Third, we summarizes the existing moral injury scales, with a focus on the scope of application and each scale’s advantages and disadvantages. These scales can be divided into two categories according to their contents, with one group assessing moral injury symptoms alone, and another assessing both the moral injury events and symptoms. Researchers or clinicians can choose these scales according to their practical needs. Moreover, current interventions for moral injury include Cognitive Behavior Therapy, CBT-based Adaptive Disclosure Therapy, CPT-based Spiritually Integrated Cognitive Processing Therapy, etc. While being commonly used in the treatment of PTSD, those therapies are equally effective in treating the core symptoms of moral injury. We concluded this article with limitations of existing research and suggestions for future research. Moral injury events and moral injury outcomes need to be further distinguished, moral injury mechanisms need to be further studied, and the diagnostic criteria of moral injury need to be established. Researchers also need to pay attention to the differences of moral standards in different cultures, expand research on moral injury to more groups, and widen the application of research on moral injury.

    Identifying people based on physiognomy: Explanations from cognitive perspective
    ZHANG Chao, WEI Xuhua, LI Yingming
    Advances in Psychological Science    2022, 30 (2): 308-323.   DOI: 10.3724/SP.J.1042.2022.00308

    Physiognomy is an important factor in identifying and inferring the individual traits and behaviors. However, its internal mechanism still needs to be further explored. Physiognomy usually refers to individual facial features, mainly including partial features and overall features. The partial features of facial features include the size and shape of the five sense organs, and the thickness of hair, while the overall features of facial features include objective facial width-to-height ratio and subjective facial attractiveness. Based on general cognitive perspective and evolutionary cognitive perspective, then combined with the local and overall features of physiognomy, this paper expounds the process and effect of judging people by physiognomy.

    The general cognitive perspective emphasizes that people study the process of cognition from the perspective of information processing, which emphasizes the process of perception. The individual’s response to physiognomy is mainly a by-product of the brain’s processing of information, which is the processing mechanism for general information. Based on stereotypes, halo effects, status generalization theory, and social information processing theory, scholars use different cognitive processing systems to illustrate the process of getting to know people and their effects. Specifically, local features such as the size and shape of the five sense organs, the thickness of the hair, and overall features such as the facial width-to-height ratio and facial attractiveness can affect individual recognition of traits such as empathy, friendliness, extroversion, self-confidence, narcissism, aggression, dominance and criminological inheritance through different cognitive processing systems. Observers’ subsequent behaviors is based on the individual traits’ information recognized by the physiognomy. On the one hand, people will judge their income, ability, and social level based on the identified individual traits. On the other hand, these individual traits play an important role in the trust decision-making, the recruitment and promotion decision-making process. All in all, physiognomy affects the recognition of individual traits through various cognitive processing systems, and these traits play important roles in judgment (ability, income, social hierarchy) and decision-making (trust, recruitment, promotion).

    Compared with the general cognitive perspective, the evolutionary cognitive perspective emphasizes that in the process of processing information, people will identify which cues are related to health, survival, propagation and adaptation to the environment according to the evolutionary needs. Based on evolutionary theory, evolutionary intrasexual competition theory and the good genes theory, scholars have discussed how to know people and its effect through two different evolutionary selection mechanisms: natural selection and sexual selection. The observer uses the gene as the driving force to identify the observed physiognomy. Observers assessed marital satisfaction, life satisfaction and happiness based on the health and genetic status they identified. In order to meet the needs of evolution and survival, people will choose a mate according to the health and genetic status of the individual identified when observing facial features, combined with the evolutionary law of "survival of the fittest". In conclusion, physiognomy plays an important role in evaluating individual health and genetic status through various evolutionary selection mechanisms, and thus has an important influence on judgment (marriage satisfaction, happiness, life satisfaction) and mate selection decision.

    In addition, the effect of physiognomy on individual life depends on the situations and individual traits. The decision situation of the face viewer, the cultural context of the face owner, and the individual traits of the face viewer and the face owner all influence the effect of physiognomy’s identification. Future research should investigate the interaction among different physiognomy features, and explore the boundary conditions that influence the effect of facial recognition. Furthermore, it is necessary to improve the external validity of the research through big data analysis, and pay more attention to physiognomy features modified by epigenetics on individuals. It is also important to conduct research within the domestic context. In doing so, it will help enrich physiognomy-related research and build a more systematic physiognomy theory.

    The linguistic patterns of depressed patients
    HUANG Guanlan, ZHOU Xiaolu
    Advances in Psychological Science    2021, 29 (5): 838-848.   DOI: 10.3724/SP.J.1042.2021.00838

    The linguistic patterns, reflected in the words people use, reveal information about psychological state and psychopathological traits. Individuals with depression are distinguishable from healthy people in their patterns of language use. Identifying the linguistic patterns, as an innovative and convenient approach, would help predict and better diagnosis depression. 
    In studies with traditional psychological methods, researchers examined the depressed language using constructed-response data. Specifically, participants are required to write or give speech on a topic (for example, participants were asked to write about their "deepest thoughts and feelings about their personal relationship" or talk about their “future career”). Participants’ responses (texts or transcribed texts) were then quantified and analyzed with the Linguistic Inquiry and Word Count (LIWC) software. Researchers found that the psychopathological traits of depressed patients were related to their linguistic patterns: the state of self-focused attention, social relationship quality and cognitive bias were respectively related to the frequency of first person singular pronouns, first person plural pronouns and emotional words in spoken and written language. It is worth to note that some variables (such as gender, communication environment and the person who are communicated with) were found moderated the relationship between language use and depression. Other factors affecting the results include the small and homogeneous sample, the limited time period researchers could track, and the weak correlations between certain words and depression. In sum, with the traditional psychological methods, researchers could hardly collect massive, longitudinal data from heterogenous participants to achieve stable results.
    Recently, studies using social media data have partly addressed these flaws. Social media provides rich and informative data. It is efficient and economical to detect depressed patients from social media users with machine learning method. What researchers do is to build a predictive model by setting the users’ social media data (for example, demographics and the linguistic content of posts) as inputs, users’ score on the standardized depression scales or their depression diagnosis as outputs. The linguistic patterns of depressed patients were generated during the feature engineering or the modeling. LIWC software is also used as the major linguistic analysis tool. These studies replicated previous findings: depressed patients used more first person singular pronouns and negative emotional words, and less first person plural pronouns and positive emotional words. Furthermore, with the social media data, researchers found more language indicators of depressed patients in daily life: they use more death words, anxiety words, swear words, anger words, religion words, health words, as well as causality words, and less second and third person pronouns. These findings are explainable by several theoretical models of depression (e.g. behavioral model, cognitive model and interpersonal model). In addition, social media based research found that the language indicators of depressed users changed in a positive way after they participated in on-line depression communities. The change was strengthened as the number of communication increased. 
    Taken together, studies using traditional psychological methods and research with machine learning complemented each other, and increased our understanding of the linguistic patterns of depressed patients. Future studies could explore other language indicators specific to depression, examine the factors that affecting word use patterns, test whether the language indicators found among Westerns fit Chinese, and strengthen related theoretical research.

    True self in east and west from Guanxi perspective
    LIANG Yanfang, XIE Tian
    Advances in Psychological Science    2021, 29 (5): 894-905.   DOI: 10.3724/SP.J.1042.2021.00894
    Abstract2596)   HTML246)    PDF(pc) (674KB)(3509)       Save

    The true self is regarded as a stable experience generated when it conforms to the autonomous motivation of the individual. To be more precise, the true self or authenticity refers to the consistency between individual behaviors and internal states (e.g., values, beliefs, and needs), including trait authenticity (that is, refers to a person's basic tendencies towards a set of emotions, cognition or behavior that reflect a stable individual difference.) and state authenticity (that is, refers to the true feeling that is consistent with one's own inner values and beliefs under the current environment or behavior). In this paper, cultural differences in the true self was proposed by comparing with relevant concepts (e.g., self-knowledge, self-concept clarity, self-congruence, integrity, and sincerity) and reviewing existent theories.

    Based on a review of previous research, this paper pointed out that the essence of the true self may not differ in different cultures, that is, the feeling when one's words and actions are consistent with one's own values. Because everyone, no matter what culture they are, experiences what it feels like to live up to their own standards. On the other hand, however, there are cultural differences in the expression or realization of the true self, or in the way it appears. This paper proposed that the true self is driven by autonomous motivation in the Western culture, while it is driven by Guanxi requirements in the Eastern culture. Specifically, Western culture focuses on individuality, and individuals seek to satisfy their own independent needs such as their own values and beliefs. It is common for western individuals to pursue their own values, beliefs and other personal independent needs, and it is normal for them to prioritize themselves over others or relationship bodies. The individual also sees the self as a major independent entity, rather than as a role player in a relationship, even in a relationship situation. Therefore, the expression of the true self is driven by the autonomous motivation of the individual in typical scenes of Western culture. However, the eastern culture, especially Chinese society, is deeply influenced by the Confucian thoughts. And the individual is in the self-centered relationship environment, and the existence and maintenance of the relationship are also internalized into the cognition of the eastern individual. Thus, the Guan xi can also be seen as a part of the self, coexists with the individual itself. The true self experience at this time is influenced by the relational environment, rather than exists in the vacuum of the detached atomic individual. That is, the true self is driven by external relational requirements in the typical scene of Eastern culture. In general, this paper pointed out that the true self is driven by autonomous motivation in the Western culture, while it is driven by Guan xi requirements in the Eastern culture.

    In multiculturalism, the consequences of cultural collision are not simple exclusion or integration, and the influence of cultural differences on true self-expression is no longer the influence of absolutely independent individuals or relationships. Under the influence of globalization, the psychological theme of the true self based on individual autonomous motivation, which is very important to Westerners, may also begin to appear in Easterners. Based on this, how does the true self behave in the complex relationship with the superior and inferior, the distant and near relatives and distant relatives? Future studies are recommended to further explore the true self from the “guanxilization”, integrating the traditional Confucian thoughts into theoretical construction and understanding toward new social phenomena (e.g., emerging Social Networking Sites, social changes), as well as advancing research methodologies (e.g., cross-cultural comparison, methods highlighting situation variations).

    The effect of cell phone distraction on pedestrians’ information processing and behavior during road crossing
    WANG Yuhan, MA Guojie, ZHUANG Xiangling
    Advances in Psychological Science    2021, 29 (5): 806-814.   DOI: 10.3724/SP.J.1042.2021.00806
    Abstract2380)   HTML312)    PDF(pc) (2275KB)(3498)       Save

    With the development of communication technology and popularization of smart phones, pedestrians using cell phones while crossing road have become more prevalent. It is estimated to account for nearly 20% of all pedestrians in both observations and self-report surveys. Consistently, the proportion of pedestrian casualties involving mobile phones during road crossing keeps increasing. This study reviewed 34 papers to evaluate how using a cell phone affected their safety and efficiency in road crossing. We also highlighted some mechanisms in terms of human information processing from scene perception, decision making to movement control.
    Overall, the evaluation shows detrimental effect of using cell phone on both safety and efficiency in crossing a road. Compared with non-distracted pedestrians, pedestrians using a cellphone are exposed to higher risk as indicated by more conflicts with vehicles, higher likelihood of violations such as going against red light and crossing outside of crosswalks, and less vigilance behaviors such as looking at vehicles. In virtual environments, they also had more collisions with vehicles or near misses where the safety margin is so small that the vehicle almost collides with the pedestrians. In terms of efficiency, pedestrians distracted by cell phones usually waited longer before starting to cross. What’s more, they are more likely to deviate from a straight route and have a lower walking speed. Consequently, their overall efficiency in road crossing declined.
    The above decline in safety and efficiency results from impairments in earlier processes of information processing. First, during the scene perception phase, distracted pedestrians tend to have a narrower scope of attention (esp. in the peripheral visual field), making it more difficult to perceive visual and auditory cues in traffic scenes. What’s worse, the distraction from a channel (visual or audial) can not only affect scene perception of the same channel, but also affect other channels by occupying central cognitive resources. Second, during the decision-making phase, distracted pedestrians are also more likely to miss street crossing opportunities when the gap between vehicles are large enough to cross or make risky decisions when the gap between the vehicle are too small to cross. Finally, using a cell phone also harms pedestrian movement control ability. Their gait patterns are more conservative with less frequent stepping and alternation between the two feet, shorter stride, and larger lateral deviation of feet movements. Besides, their action stability declined as a result of trying to reduce the relative movement of cellphones and head while browsing messages from cell phones.
    The above impairments of information processing are modulated by specific task types (e.g. conversing vs. browsing), pedestrian age and experience in cell phone usage. To integrate these findings within a framework, a conceptual model was proposed to describe the effect of mobile phone distraction on pedestrians’ information processing and behavior based on previous pedestrian cognitive models. Based on the model, we highlighted several gaps for future research. In the scene perception phase, future research needs to evaluate how mobile phone distraction affects pedestrian auditory scene perception, which is important to locate risky targets in traffic scenes. During the decision-making phase, efforts are still needed to evaluate how using a cell phone impacts the sub processes within the gap acceptance decision-making, such as estimation of vehicles’ time to arrival and pedestrians’ needed time to cross a road. The evaluation will help to develop targeted interventions to improve pedestrian safety while using cell phones.

    The effects of gender nonconformity on adolescent peer evaluation and related dynamics
    WEN Fangfang, KE Wenlin, FANG Zeming, WANG Yang, LEI Yatian, ZUO Bin
    Advances in Psychological Science    2023, 31 (8): 1331-1341.   DOI: 10.3724/SP.J.1042.2023.01331

    Inherent gender is an important dimension of self-identity and social categorization, and has a huge impact on individual psychology, interpersonal relationships, intergroup behaviors and social development. Gender stereotypes, gender socialization and gender attitudes have been stable themes in disciplines, such as social psychology, developmental and educational psychology and sociology. Gender is the core component of the self-concept and an important dimension of social categorization. Gender Nonconformity is a psychological phenomenon in which individuals display gender norms that do not correspond or are inconsistent with their birth sex. In recent years, the phenomenon of Gender Nonconformity has become increasingly prominent among adolescents, and previous studies have shown that Gender Nonconformity adolescents face challenges in social adjustment such as peer relationships. Although some research paradigms and theoretical findings have been accumulated in the area of Gender Nonconformity and related areas, there are still limitations. Although some research paradigms and theoretical findings have been accumulated in the area of Gender Nonconformity and related areas, there are still limitations. Firstly, previous studies have mainly adopted the traditional binary approach of gender conformity and non-conformity; secondly, there is a lack of cognitive-motivational pathways to examine the prototypical matching and avoidance intentions of Gender Nonconformity in influencing adolescents' peer evaluations; thirdly, previous studies have mainly adopted a static perspective on gender-biased peer evaluations, ignoring the dynamic processes of gender-biased generation and evolution. To address these limitations, this study will break through the gender binary category and explain the psychological mechanisms of static effects and dynamic changes of Gender Nonconformity on peer evaluation from the perspective of the relationship between basic attributes and gender attributes, and provide possible interventions to change the negative peer evaluation of Gender Nonconformity individuals. The specific aims of the study include: firstly, to develop and provide neurophysiological evidence for the basic attributes of Gender Nonconformity; secondly, to reveal the cognitive-motivational dual-path mechanism of prototype matching and avoidance intention in the process of Gender Nonconformity influencing peer evaluation; and thirdly, to explore the dynamic evolutionary mechanism of Gender Nonconformity influencing peer evaluation.

    Focusing on the above three research aims, this study systematically examines the influence of Gender Nonconformity on peer evaluation and its evolutionary psychological mechanisms according to a progressive research hierarchy of "realization layer - algorithmic layer - computational layer". The study includes three aspects. (1) A polymorphic refinement examines the effects of Gender Nonconformity on peer evaluation, constructs a view of the underlying attributes of Gender Nonconformity and provides behavioral and neurophysiological evidence of the layers of realization. (2) A dual cognitive-motivational pathway mechanism for Gender Nonconformity to influence peer evaluation is revealed at the algorithmic level. The social cognitive paradigm is used to explore the cognitive activation of "prototype matching" and the motivational activation of "intention to avoid" in the process of Gender Nonconformity influencing peer evaluation through questionnaires, behavioral experiments and situational experiments. (3) Exploring the dynamic evolutionary mechanisms of Gender Nonconformity in peer evaluation from the abstract computational level. Using reinforcement learning paradigms, computational modelling, implicit measurement, contextual experiments and live experiments, the prototype formation process of Gender Nonconformity peer evaluations is simulated using reinforcement learning models based on a dual pathway of cognition and motivation to explore the dynamic evolutionary mechanisms of gender-biased peer evaluations and possible intervention pathways for negative peer evaluations of gender-biased individuals. The findings of this study can provide some managerial and educational insights into the effective promotion of youth gender development, peer relationships and mental health based on a gender perspective.
