    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.

    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.

    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.

    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

    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.

    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
    Abstract2540)   HTML188)    PDF(pc) (574KB)(4080)       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.

    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.

    Conceptualization of time poverty and its impact on well-being: From the perspective of scarcity theory
    SUN Xiaomin, YANG Shuting, KONG Xiaoshan, LIU Zhenzhen, MA Rongzi, YUAN Yue, ZHANG Nan, JIANG Xinying, CAO Peiling, BAO Ruiji, LIN Yiqin, LI Ning, LI Zhihang

    In today’s fast-paced world, increasing numbers of individuals are facing time poverty, i.e., having too much to do and not enough time. It can impact people's cognitive processes and behaviors by affecting their attention. However, the extant literature provides only a limited understanding of the influence of time poverty and its effects on individual multi-faceted well-being. Therefore, a comprehensive investigation of the concept of time poverty and its impact on well-being is of great importance theoretically and practically. The current study intends to present a three-dimensional theoretical model for the construct of time poverty from an integrated perspective, aiming to explore its effects on multi-faceted subjective well-being and investigate the potential mechanisms by which time poverty reduces well-being based on scarcity theory.

    Specifically, the current study proposes a three-dimensional structure for the concept of time poverty, which includes length, intensity, and quality. Most researchers agree that spending an excessive amount of time on paid work or unpaid domestic work and having an insufficient amount of free time leads to time poverty. Moreover, the number of tasks to be completed per unit of time may be an independent source of pressure resulting in the perception of time poverty. The stressful pace caused by over-rapid task completion and too short intervals could increase the sense of time poverty. Lastly, the quality dimension of time poverty comprises time integrity, time autonomy, and time synchronization. Low time quality could worsen the perception of time poverty. Based on the three-dimensional model of time poverty, the current study aims to develop a time poverty scale and construct a large-scale Chinese time poverty database. This database is designed to collect demographic information as well as the level of time poverty of representative samples, aiming to explore the dominant type of time poverty for different demographic groups and trace the dynamic changes in time poverty over time.

    Furthermore, the current study proposes that time poverty can have a significant impact on people’s well-being. Time poverty can develop a scarcity mindset, leading people to focus on the scarcity of time. Consequently, they overemphasize productivity, resulting in a strong inclination of completing more tasks in a shorter amount of time. Such a mindset shifts people’s attention from the activity’s process to its results, reducing intrinsic motivation and, as a result, ruining people’s well-being. An excessive focus on productivity can also harm interpersonal and family well-being by underestimating the importance of investing time and energy in nurturing relationships, thereby lowering the quality of relationship-oriented interactions. Therefore, we argue that by promoting the over-productivity orientation, time poverty can adversely affect individual, interpersonal, and family well-being. Furthermore, time poverty in one spouse's workplace produces an over-productivity tendency which then spills over to the family environment and is conveyed to the other spouse in their daily interactions. Such processes are likely to negatively influence both parties’ well-being.

    Overall, the current project develops a three-dimensional time poverty theoretical model, based on which a time poverty scale will be developed. With the new scale, a large-scale database will be constructed. The project will explore the experiences of different groups of people with distinct characteristics in Chinese society, and how such experiences influence personal, interpersonal, and family well-being. The results of the current project are of great importance for not only the successful coping of time poverty for individuals but also for societies aiming to improve the well-being of their people.

    The cognitive psychological process of brand consumption journey: The perspective of neuromarketing
    XIE Ying, LIU Yutong, CHEN Mingliang, LIANG Andi
    Advances in Psychological Science    2021, 29 (11): 2024-2042.   DOI: 10.3724/SP.J.1042.2021.02024

    Brand consumption journey usually refers to the multi-dimensional (including cognition, emotion, feeling, behavior and brand relationship) response to brand consumption service. Revealing the cognitive psychological process of brand consumption journey is the focus and hot spot in the field of marketing. Based on the summary of the domestic and foreign research results involving brand marketing, consumer psychology and decision neuroscience, this paper divides the brand consumption journey into four stages: attention attraction, decision-making, consumption experience and brand loyalty. Meanwhile, this paper reveals the cognitive psychological process of consumers in the journey of brand consumption from two levels (consciousness and subconsciousness): in the stage of attention attraction, consumers process the perceived product information and form target attention through the perceptual pathway of the brain, and the activation degree of nucleus accumbens (NAcc) and anteriorinsula (AIns) can reflect consumers' attention to products, The N1 and P2 components of ERP are closely related to the formation of visual attention. The alpha ERD of ERO represents the formation of attention attraction and the allocation of early attention resources. In the decision-making stage, consumers form an estimate of the expected value of products in the striatum and other brain regions, and make a purchase decision after weighing it with the price. The P3 and SW components of ERP can reflect the confidence of decision-making, and the gamma ERS of ERO can reflect the decision-making process of value integration of product information. In the stage of consumption experience, consumers' emotional pleasure is reflected in the medial orbitofrontal cortex and other brain areas. Emotional changes will lead to changes in P2 and LPP amplitudes of ERP. Emotional experience is related to theta ERS, gamma ERS, delta ERS and alpha ERD of ERO. Finally, in the stage of brand loyalty, consumers conduct consumption learning based on the structure of striatum, caudate nucleus and hippocampus, and the results will lead to consumer loyalty (or disloyalty). The late positive component of 500~800 ms in ERP may be related to brand loyalty, while theta ERS in ERO may be related to consumer memory and product immersion experience, which reflects customer loyalty. Future research can further explore the representational meaning of different neural indicators in specific marketing situations, and analyze the neural coupling between multiple subjects by applying with hyperscanning technology.

    Conservation of resources theory in the organizational behavior context: Theoretical evolution and challenges
    LIAO Huahua, HUANG Lei, HU Bin
    Advances in Psychological Science    2022, 30 (2): 449-463.   DOI: 10.3724/SP.J.1042.2022.00449
    Abstract4518)   HTML205)    PDF(pc) (847KB)(3625)       Save

    Over the past three decades, the conservation of resources theory (COR) has become one of the most widely applied theories in organizational behavior (OB).

    Hobfoll (1989) proposed COR as a new attempt at conceptualizing the stressor-strain relationship. It highlights that stress is not construed by individual perception but a reaction to objective stressful circumstances; coping in reaction to stress is a dynamic process of exchanging resources between individuals and the environment. Imprinted by Hobfoll’s background as a clinical psychologist studying stress disorder, COR is recognized as a resource-oriented stress model with environmental roots After several major revisions, COR has developed from a stressor-strain model into a motivational theory and built a theoretical framework with several extensions. The dynamic process regarding how people strive to acquire, protect, and build resources helps to explain individual behaviors in reactions to stressors across many organizational contexts. COR also shed light upon how organizations cope with stress.

    From 1989 to 2020, OB literature has accounted for most citations of the 1989 paper that initially introduced COR theory. A great number of empirical studies in the OB field, covering a variety of themes such as job stress, work engagement, creativity, and leadership, investigated the major propositions in COR. These propositions include resource loss and gain spirals, salience of resource gain in the process of resource loss, and more. As a result, COR has become one of the most influential theories for understanding employees’ psychological processes and behavioral motivation. However, OB scholars share concerns about COR that the concept of resource is fuzzily defined and therefore that nearly anything good can be considered a resource. We acknowledge the substantive value of COR in OB literature though it may not sound novel, but we also recommend OB scholars be conscious with its conceptualization while applying COR and not take the value of applying it by granted because of its high citations.

    Applying COR in OB research also faces challenges from other theoretical perspectives. For example, the stress-appraisal theory and the adaption theory provide some contrasting viewpoints on stress. Its origin in clinical psychology also invites problems for OB scholars that they tend to ignore the integrative perspective of COR regarding how the sources of stress and the structure of individual resources evolve in a dynamic process.

    We propose that OB researchers should avoid tailoring COR’s propositions to OB research questions, which often means neglecting its overarching perspective and purposely selecting isolated viewpoints to serve their own research questions, but try to seek balance between the integrative perspective in COR theory and the behavior-focused tradition in OB research in the future.

    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.

    Effects of ambient light on mood and its mechanism
    LI Yun, RU Taotao, LI Siyu, CHEN Hanyu, XIE Shuya, ZHOU Guofu
    Advances in Psychological Science    2022, 30 (2): 389-405.   DOI: 10.3724/SP.J.1042.2022.00389

    As an essential timing factor, ambient light plays a vital role in synchronizing internal biological rhythms with external lighting and dark environments. Meanwhile, ambient light is also a critical mood regulator; its non-image-forming (NIF) effects on mood are especially concerned by researchers. Previous studies have demonstrated that illuminance, correlated color temperature (CCT), and wavelength of ambient illuminance are key physical factors affecting mood. Moreover, unusual lighting patterns such as short lighting periods, artificial lighting during the night, and constant lighting/darkness have destructive effects on emotion and mood that may induce affective disorders such as depression and anxiety.

    To date, the conclusion that short-time light affects emotion is not quite consistent. Studies have found that the NIF effects of short-term light on mood was not only affected by the intensity and spectrum of light, but also modulated by exposure duration, timing, individual characteristics, subjective preferences, and gene types. In a period of time, the longer the subjects received bright light exposure and the earlier they received morning light exposure, the lower their depression score. However, in the short-term lighting experiment of simulating office lighting, prolonged exposure of bright light was not conducive to individuals’ subjective emotional experience; while the positive effect of CCT on emotion may depend on prolonged exposure. It is worth noting that receiving light exposure at different time in a day can advance or delay the circadian rhythms; thus, the timing could also regulate light’s emotional function. In addition, women were found to prefer higher illuminance and lower CCT than men; while young subjects were more sensitive to polychromatic light with shorter wavelength than older subjects. Compared with individuals with PER34/4 genotype, individuals with PER35/5 genotype were more sensitive to light exposure and had a higher risk of depression; the 5-HTTLPR polymorphism was also proved to regulate the effect of light on the functional connectivity of the prefrontal cortex in healthy subjects. Lastly, the mechanisms by which light affects mood are shown from two aspects. On the one hand, the intrinsically photosensitive retinal ganglion cells may project light signals to the brain areas responsible for emotion regulation. On the other hand, ambient light may affect mood by altering circadian rhythms, regulating hormone secretion, neurotransmission, and sleep.

    Future research can employ neuroscience technology to simultaneously examine the changes of subjective emotional experience and objective neural activity under multi-levels of illuminance and CCT; and combine multimodal data such as subjective rating, behavioral measurement, physiological response, and neural activity to track the effects of ambient light on mood. Besides, except for the NIF of light, ambient light may convey specific emotional meanings via the visual system, thus leading to various visual experiences transmitted by illuminance or wavelength, or lighting mode (direct or indirect lighting). Therefore, whether the visual perception of light, dominated by rods and cones, also potentially contributes to light's emotional function and how to separate it from the non-visual effects could be a promising direction in future research.

    The relationship between socioeconomic status and depression: A systematic review and meta-analysis
    ZHANG Yali, ZHANG Jiangen, LI Hongxia, JIANG Yongzhi
    Advances in Psychological Science    2022, 30 (12): 2650-2665.   DOI: 10.3724/SP.J.1042.2022.02650

    Socioeconomic status is an important topic concerned by social class psychology. With the transformation of social development, its influence on individual psychological development has been paid increasing attention. In recent years, scholars in different fields have carried out a series of discussions on the relation between socioeconomic status and mental health, especially depression, but results remain mixed. Some have reported negative correlations between socio-economic status and depression, and others have found weak to nonsignificant correlations. In general, the reported correlation coefficients ranged from -0.45 to 0. At present, no studies have systematically generalized the scattered results on this topic, nor have they dissected the reasons for the inconsistent results. Therefore, it is necessary to gain better insight into the relation between socioeconomic status and depression, and the factors that affect this relation. At the same time, China is in the deep-water area of reform and development. The rapid economic development has made the gap between the rich and the poor increasingly intensified, and it has also made class mobility more difficult. Therefore, exploring the relation between socio-economic status and depression can provide a more detailed basis for the formulation of the current social mental health service system in China.
    In Chinese database (China National Knowledge Infrastructure database), the keywords “社会地位” or “经济地位” were respectively matched with “抑郁”, and the literatures with such keywords in the abstract were searched. In foreign databases (Web of Science Core Collection, Elsevier SD, PsycINFO, PsycArticles, and ProQuest Dissertations and Theses), the keywords “socioeconomic status”, “socio-economic status”, “social class”, and “social status” were matched with “depress*” respectively, and the literatures with such keywords in the abstract were searched. In addition, to avoid omissions, literature supplementation was performed through citations during literature reading and Google Scholar. Finally, a total of 11110 studies were obtained. After literature screening, a total of 58 studies (including 65 effect sizes and 76,715 participants) were finally included, with a time span from 1973 to 2022. The correlation coefficient r was used as the effect size, and the random effects model in software Comprehensive Meta-Analysis Version 3.0 was used to conduct the meta-analysis.
    The main effect analysis indicated a small significant negative correlation between socio-economic status and depression (r = -0.15). Further sensitivity analysis showed that the estimated effect size fluctuated between-0.158 and -0.147, indicating that the estimated result was stable. The moderating effect analysis showed that: (a) The moderating effect of the sampling year was significant (b=-0.008, 95%CI [-0.015, -0.001]), and the relationship between socioeconomic status and depression became stronger with the development of the times; (b) The moderating effect of SES measurement tool is significant, and the correlation measured by SSS is the strongest, while the correlation measured by FISS or principal component analysis was the weakest; (c) The moderating effect of SES measurement type was significant, and the correlation between subjective socioeconomic status and depression was higher than that of objective socioeconomic status;. (d) The moderating effect of SES measurement form was significant, and the correlation between family socioeconomic status and depression was lower than that of one's own socioeconomic status; (e) The moderating effect of depression measurement tool was marginally significant, the correlation measured by SCL was not significant, and the correlation measured by CDI or CESD was higher than other tools; (f) Gender, age, individualism index and design form (cross-sectional design vs longitudinal design) had no significant moderating effects on the relationship between socioeconomic status and depression.
    This is the first study to analyze the overall strength of the association between socioeconomic status and depression. The results showed that there was a significant negative correlation between them, indicating that relevant public policies should be formulated and supporting schemes should be provided to care for the socio-economic disadvantaged groups, especially to improve their education and income levels, so as to prevent the occurrence of group depression. In addition, the present study also found that the effect size was affected by many operational characteristics (i.e., socio-economic status measurement type and depression measurement), suggesting that future researchers should pay more attention to the choice of scales when conducting research. Specifically, for socioeconomic status, objective and subjective indicators should be combined as far as possible, and it is best to directly measure the socioeconomic status of the individual rather than the family. For depression, scales that measure too few depressive symptoms should be avoided as far as possible. This study also found that the effect size is affected by the development of the times, suggesting that China should vigorously promote the policy of common prosperity in the new era, promote class mobility, prevent class solidification and the further expansion of the gap between the rich and the poor, so as to reduce the occurrence of depression from the social level. Finally, although age and research design failed to moderate the relation between socioeconomic status and depression, both essentially reflect the long-term effect of socioeconomic status on individual's depression. This suggests that public services and public policies should pay attention to long-term effectiveness in the implementation.

    The relationship between disgust and suicidal behavior

    Advances in Psychological Science    2023, 31 (1): 87-98.   DOI: 10.3724/SP.J.1042.2023.00087

    Suicide is the primary cause of adolescent death, and suicide seriously endangers the life security and mental health of human being. Suicidal behavior includes suicidal ideation, suicidal attempt and suicide. Suicidal ideation refers to serious suicidal thoughts of preparing for a fatal, self-directed, and potentially injurious behavior, or refers to the intension to die without specific plans. Suicidal attempt refers to the intension to commit suicide, including the plans for suicide and even committed suicide; they might attempt to attract attention through bodily harm, but not necessarily causing actual harm. However, suicide is self-directed harm or death. According to suicidal theories which were based on the ideation-to-action framework, self-disgust is a key factor for the formation of suicidal ideation. This article reviews theoretical basis, correlation factor and neurophysiological mechanism of disgust induced suicidal behavior, and predicts future research direction.

    Many recent studies suggested that many psychological problems, including suicide, are caused by patients' disgust to the surroundings and the environment. Disgust is a basic emotion, which is a response to disgustful things, and it is a defensive mechanism to keep people away from spoiled foods or from pollutants to prevent potential diseases, viruses and pollution. However, under heavy burdens and pressures, people would feel depressed and self-disgust, and ultimately lead to despair (extreme self-disgust), resulting in suicidal ideation. Under the condition of having suicidal ability, suicidal ideation would turn to be suicidal attempts, and thus suicide.

    It is also suggested that early life trauma might be the root for disgust inducing suicidal ideation. And life stress and mental illness might aggravate the induction of disgust to suicide. High-intensity self-disgust has been proved to be the most relevant predictor of suicidal risks in mental illness. Psychoanalysis shows that when people are disgusted by themselves, the aggression behavior induced by disgust would also be directed to themselves, so self-disgust might induce suicide.

    The neural mechanism of self-disgust inducing suicide may be related to monoamine (including serotonin) and oxytocin. Hypothalamic-pituitary-adrenal (HPA) axis are related to the stress response system that plays a very important role in disgust-induced suicidal ideation. Besides, self-disgust may be affected by traumatic stresses in early life, current psychological problems and mental diseases, which might lead to the mal-development of 5-hydroxytryptamine (5-HT) system, that determines the pattern of stress response in adulthood, including suicide.

    However, there are still some limitations in current suicide studies. First of all, most studies are still limited to cross-sectional design and cannot compare time factors. Therefore, future studies should adopt vertical design and prospective research. Secondly, since most studies are limited to questionnaire studies, future studies could apply neuroscience technologies, such as neuroimaging and electrophysiology, in investigating the neural mechanisms of suicidal behavior, as well as the psychological and neural mechanisms of suicidal behavior affected by disgust.

    High school is the key period of psychological development, and it is also the frequent period of a variety of psychological problems. The mental health problems of senior high school students not only come from adolescents themselves, but also should attract extensive attention from families, schools and society. In order to improve the mental health of senior high school students and ensure the effective development of follow-up mental health work, it is necessary to understand the detection rate of mental health problems of senior high school students in China, so as to master the basic situation of mental health of senior high school students. Although many previous studies have involved the detection rate of mental health problems of senior high school students, there is no consistent conclusion on the detection rate of mental health problems of senior high school students in China in recent ten years. In order to clarify the detection rates and influencing factors of mental health problems of senior high school students in China in recent ten years, this study makes a comprehensive and systematic meta-analysis of the relevant detection rate articles of senior high school students (including higher vocational students) in recent ten years, so as to form a clearer understanding of the general situation of their mental health. Because there are too many indicators involved in mental health problems, this study focuses on the detection rate of two common problems in senior high school students: internalizing problems (including anxiety, depression, sleep problems, somatization, suicidal ideation, and suicide plan) and externalizing problems (including self injury and suicide attempt. In addition, this study also investigated the regulatory effects of publishing age, relevant factors of measurement tools (measurement tools, detection standards, detection time), and demographic variables (grade, region, gender, only child or not, birthplace) on the detection rate of mental health problems.
    By searching the Chinese National Knowledge Infrastructure database and Web of Science core collection database from 2010 to 2020, 252 effective literatures were finally obtained, including 48 articles on anxiety, 99 articles on depression, 21 articles on sleep problems, 14 articles on somatization, 29 articles on self injury, and 41 articles on suicide. The results of meta-analysis showed that (1) The prevalence from high to low were depression (28.0%), anxiety (26.3%), sleep problems (23.0%), self-injury (22.8%), suicidal ideation (17.1%), somatization (9.8%), suicide plan (6.9%), and suicide attempt (2.9%); (2) In the past ten years, the mental health problems of senior high school students in China have deteriorated with the passage of time, especially anxiety; (3) The detection rate of mental health problems of senior high school students is affected by the relevant factors of measurement tools (measurement tools, detection standards and detection time); (4) The mental health problems of senior high school students increased with the increase of grade, especially sleep problems; (5) The mental health problems of senior high school students were affected by regions, especially in economically underdeveloped areas. It can be seen that the prevalence of mental health problems of senior high school students in China was affected by the year of publication, measurement tools, detection standards, detection time, grade and region. In the future, efforts should be made to prepare standardized evaluation tools, build a long-term mechanism of mental health education, and focus on the mental health problems of senior class and underdeveloped area senior high school students.

    With the methodological changes in psychology, more and more researchers tend to accept qualitative research as an effective way to solve psychological problems and serve the public. In a qualitative study, sufficient sample is the guarantee of research validity, and saturation is an indicator used to assess the adequacy of research data. Saturation means that on the basis of the currently collected and analyzed data, further data collection will not help researchers develop a deeper understanding of the story or theory, so there is no need to continue to collect data. The concept of theoretical saturation was first proposed in grounded theory. Then with the development of qualitative research methods, researchers have further created more saturation concepts, including data saturation, code or thematic saturation, meaning saturation, etc. Due to the diversity of saturation and its judgment standards, the relationship between different kinds of saturation are complicated and ambiguous. In addition, previous studies lack operational description and practical guidance for the evaluation of saturation, which leads to the vagueness of the concept of saturation and many difficulties in evaluation. In order to solve these problems, this study clarified the concepts and evaluation methods of four levels of saturation, and provided suggestions for researchers' operations based on comparison and analysis. The four types of saturation occur at different stages of the research process, and each has its own specific connotations. Data saturation, code or thematic saturation focuses on the breadth of collected data, while meaning saturation and theoretical saturation focus on the depth of research data. In terms of evaluation methods and criteria, researchers usually judge data saturation based on the repeatability of initial data; code or thematic saturation is determined based on empirical research results, the emergence of new codes or themes, or saturation coefficients; the results of retrospective empirical analysis or tables of meaning unit are normally used to evaluate meaning saturation; while the assessment of theoretical saturation relies on a process called "continuous comparison" in grounded theory, which focuses on the continuous improvement of the theory. Some problems are discussed in this study. 1) The sample size standard for reaching saturation should be embedded in the specific research process instead of being uniformly set in advance. Because each study has its own uniqueness in terms of questions, purposes, methods, etc., which saturation is extremely sensitive to, the evaluation of saturation should be based on the characteristics of the current research to select an appropriate level of saturation. 2) Due to the logical uncertainty of saturation, a little oversampling would be helpful. The logical uncertainty here means that researchers can only predict the necessity of continuing data collection based on the information that has been collected, which relies on the subjective judgment of researchers, and its accuracy can never be further proved. Oversampling may be an effective way to solve this problem, which means that even if saturation has been achieved, the researcher is recommended to add 2 to 3 personal interviews or 1 to 2 focus group interviews to further confirm. 3) As an important index to evaluate the quality of qualitative research, saturation is not suitable for all qualitative research, such as psychobiography, narrative analysis, etc., which focus on single or a few cases and pay more attention to the integrity of individual stories. In the future, researchers should further focus on the evaluation and testing of saturation in different kinds of qualitative research.
