Abstract： Socioeconomic disparities in health are the realities individuals have to deal with throughout the life span, and are issues all the nations need to face worldwide. Theories and empirical work have attempted to understand socioeconomic disparities in health from life-span perspective. In studies from life-span perspective, socioeconomic disparities in health have its unique definitions and assessment tools. Key theories include cumulative (dis) advantage hypothesis, cumulative inequality model, and cultural cycle model of social classes. Researchers have examined socioeconomic disparities in health in childhood, adolescence, early adulthood, and old age. Future directions of research from life-span perspective should focus on the interaction between socioeconomic status in childhood and adulthood, the distinction of long-term and temporary socioeconomic status, and the potential of psychosocial interventions for health equality across disciplines. Research on socioeconomic disparities in health from life-span perspective may deepen the understanding for the developmental roots of socioeconomic disparities in health and should serve as an important theoretical basis for promoting health and implementing clinical practical work on health equality.

Abstract： Dr. Sun Yat-sen was one of the three greatest figures in the modern Chinese history and has made tremendous contribution to the independence, liberation and revival of modern China. In the past decades, Sun's ideologies have been well researched in academic fields such as philosophy and politics. However, there is a lack of discussion about Sun’s thoughts from a psychological perspective. The theory of mind construction plays an extremely important role in Sun's strategies of political revolution and nation building. Sun emphasized the importance of social psychology in social politics and the importance of mind construction in human development. The mind construction theory can be seen as an important theoretical guide and practical reference to the rejuvenation of modern China. The theory of mind construction is concerned with the development of people and society, with the main purposes to educate people, change conservative mindsets, unite people's heart and strength, and eventually promote the common progress of society. The key to this ideological breakthrough was the establishment of the doctrine of "difficult to know and easy to do", which embodies Sun's understanding of the relationships between knowledge and practice, and emphasizes the difficulties and importance of scientific exploration. The mind construction theory is a concise summary of Sun’s experience in revolutionary politics and history, and is characterized by the following features: the integration and innovation of Chinese and Western civilizations, the convergence of material and ethical civilization, and the emphasis on the relationship between human psychology and politics. It is the development and innovation of the spirit of the times. It enlightens us to draw wisdom from our efforts to build a new society that is closely integrated with the highly developed material civilization and the vigorous humanistic spirit. Sun's thoughts of nation building, as the first step in mind development, explored the unique Chinese way to political success, and provided important inspiration for the sacred cause of the Chinese Renaissance in the 21st century. It is noteworthy to know that Dr. Sun Yat-sen was aware of the dialectical relationship between material and ethical civilizations, the energy of the spirit, and the importance of material construction. Moreover, we must pay attention to the positive role of mind construction in current social governance policies. Thus, it is of important theoretical and practical values to revisit, inherit, and creatively implement Sun's mind construction thought.

Abstract： The left middle frontal gyrus (MFG) is a typical region identified in the brain mechanism of Chinese character reading. A common view suggests that the MFG is responsible for visual-spatial processing in reading Chinese characters, since the Chinese writing system has extremely complex structures. However, this explanation has not received direct evidence. Moreover, which kind of visual-spatial analysis underlying the MFG's activation is not clear. The current functional Near-Infrared Spectroscopy (fNIRS) study examined the functional role of the MFG in Chinese character reading by directly manipulating the spatial frequency characteristics of the Chinese character materials.The experiment adopted a 3 (characters type: Real, Pseudo, and Artificial character) by 3 (spatial frequency: Full, Low, and High spatial frequency) within-participant factorial design. All Real characters were phonograms containing two components: phonetic and semantic radicals. The phonetic radical was not pronounceable and meaningless. The semantic radical was not pronounceable and meaningful that can provide the meaning category. The Pseudo characters were created by switching the position of radicals from Real characters. The Artificial characters were scrambled strokes from Pseudo characters. Each type of character was presented in three ways with different spatial frequencies: Full, Low, and High spatial frequency. In the Full spatial frequency, items were typical stimuli. In the Low and High spatial frequency, items were spatially filtered by Gaussian filter to remain the low/high spatial frequency features. Each type of character has 60 stimuli. All 540 stimuli for nine conditions were presented in 6 runs. Each run contained 1~2 blocks for each condition and lasted for about 8 minutes. Thirty-one participants took part in the experiment to perform a one-back task in each block by detecting whether the current stimulus was the same as the previous one. Meanwhile, a multi-channel fNIRS system was used to record brain activity at the left MFG.The results found a significant main effect of character type at left MFG. The activation of MFG was stronger for Pseudo characters than for Real and Artificial characters. The left MFG also showed a significant interaction between character type and spatial frequency. The difference among the three types of characters was significant for Low spatial frequency but not for Full and High spatial frequency. For materials presented in Low spatial frequency, Pseudo characters elicited more robust activation than Real and Artificial characters. These results suggested that the left MFG was sensitive to the spatial information of Chinese characters, especially for materials presented in low spatial frequency and for materials that required more graphemic/orthographic processing.In sum, the finding provided direct evidence that the left MFG engaged in visual-spatial processing in Chinese character reading.

Abstract： The quality of decision-making in older people decreases with age. In medical decision-making, poor medical decisions in older adults can have a range of adverse effects. Therefore, exploring the influencing factors of the quality of medical decision-making is necessary. Aging stereotypes are closely related to the quality of decision-making. Negative aging stereotypes will have a negative impact on the decision-making of older adults. However, the relationship between aging stereotypes and the quality of medical decision-making has not been fully studied, and the mechanism between the two remains unclear. As an important concept in social cognitive psychology, attribution bias is closely related to aging stereotypes and medical decision-making. When encountering behaviors or phenomena consistent with stereotypes, people are more inclined to attribute such behaviors internally to maintain the stereotypes. Furthermore, attribution bias is an important factor in decision-making, and the attribution bias of the older adults will have a significant impact on their subsequent treatment decisions. Nevertheless, the role of attribution bias in the relationship between aging stereotypes and medical decision-making in older adults remains unknown. Thus, this study attempts to clarify the relationship between aging stereotypes and medical decision-making and reveal the mediating role of attribution bias in the relationship between aging stereotypes and medical decision-making. This study has two experiments. Experiment 1 attempted to explore the relationship between aging stereotypes, attribution bias, and quality of medical decision-making in older adults. Experiment 2 attempted to verify further the relationship between the three by training attribution bias. Seventy-eight older adults (26 males and 52 females) were recruited as participants in Experiment 1. All participants were randomly assigned to the stereotypes threat group or the control group. Attribution bias and the quality of medical decisions in both groups were then measured. Eighty participants (30 males and 50 females) were recruited in Experiment 2. All participants were randomly assigned to the stereotypes threat group or the attribution bias intervention group. First, the aging stereotypes of all participants were activated. Participants in the stereotype threat group completed the same measurement as Experiment 1. Participants in the attribution bias intervention group completed attribution bias measurement and medical decision-making tasks after attribution bias control training. SPSS 25.0 was used for the statistical analysis of the data. Experiment 1 found that the aging stereotypes negatively predicted the quality of medical decisions and increased the internal attribution bias. The internal attribution bias in the stereotype threat group was significantly higher than that in the control group, and the quality of medical decision-making was substantially lower than that in the control group. The study also found that internal attribution bias was mediating in the relationship between aging stereotypes and medical decision quality. Results of Experiment 2 show that the internal attribution bias of participants in the attribution bias intervention group was significantly lower than that in the stereotypes threat group, and the quality of medical decision-making was significantly higher than that in the stereotypes threat group. That is, aging stereotypes negatively affected the quality of medical decisions, and internal attribution played a mediating role between the two. Furthermore, the control training of attribution bias can effectively alleviate the adverse effects of stereotypes in old age. This study enriches the previous research on the influence of stereotypes on decision-making. It has certain practical value for alleviating the negative effect of stereotypes in older adults and improving the quality of individual medical decision-making.

Abstract： The event-related potential (ERP) studies have revealed a component (N170) near tempo-occipital electrodes was sensitive to visual words. However, its role in word reading is still controversial. A common view is that the N170 engaged in the visual/orthographic processing, whereas some evidence has shown the N170 involved in phonological and semantic processing. By taking advantage of the Chinese writing system's ideographic property, the current study directly examined whether the N170 was sensitive to the phonological and semantic processing in reading Chinese characters. Two ERP experiments were conducted in a neural adaption paradigm by manipulating the repetition of the sub-lexical phonetic/semantic radical. The ERP data were collected while participants performed a phonological judgment task on the 4th character after silently reading the four characters consecutively. The phonological similarity (Experiment 1) and semantic similarity (Experiment 2) were manipulated among the four characters. Experiment 1 examined the neural adaption of the four characters sharing the phonetic radical (e.g., 敏, 侮, 悔, 莓), the character's pronunciation (e.g., 妹, 枚, 镁, 莓), both of them (e.g., 酶, 梅, 霉, 莓), or neither (e.g., 淮, 崛, 郎, 莓) respectively. Experiment 2 examined the neural adaption of the four characters sharing the semantic radical (e.g., 狡, 狂, 猜, 狒), the character's meaning (e.g., 豹, 鹿, 羚, 狒), both of them (e.g., 狮, 狼, 狐, 狒), or neither (e.g., 淮, 崛, 郎, 狒) respectively. In both experiments, the results showed a significant neural adaption at N170 in all of the four conditions. The amplitude of the N170 observed in the 1st character decreased in the 2nd - 4th characters. In Experiment 1, the N170 neural adaptation at the left PO7 electrode was sensitive to the repetition of the phonetic radical, and the repetition of the character's pronunciation, but not to the repetition of both. These results indicated the left mid-fusiform gyrus might be sensitive to the visual/orthographic and phonological processing but not to the orthography-to-phonology mapping in Chinese character reading. In Experiment 2, the N170 neural adaption at the left PO7 electrode was only sensitive to the repetition of the character’s meaning, which indicated the semantic processing might modulate the left N170 in character reading. The N170 neural adaption at the right PO8 electrode was sensitive to the repetition of the semantic radical and the character's meaning, which suggested that right N170 was involved in visual/orthographic and semantic processing in reading characters. In sum, the findings showed that the N170 was involved in the visual/orthographic processing and engaged in the phonological and semantic processing in Chinese character reading. Furthermore, the left N170 was sensitive to the character's phonological and semantic information, whereas the right N170 was sensitive to the character’s meaning and its semantic radical.

Abstract： As a critical positive psychological construct, gratitude is crucial for health and well-being. Previous studies have shown a significant positive correlation between gratitude and social well-being. Although it is proven that gratitude causes higher social well-being, little research has explored the effect of social well-being on gratitude. Based on the personal and social relationships model and self-determination theory, our research proposed that social well-being is an antecedent to gratitude. Thus, in this study, we aimed to examine the longitudinal relationship between gratitude and social well-being. The hypotheses are as follows: 1) Gratitude has a direct effect on social well-being; 2) Social well-being has a direct effect on gratitude; or 3) Gratitude and social well-being have reciprocal effects on each other. Two studies were designed to test the hypotheses. Study 1 adopted a two-wave cross-lagged design to explore the relationship between trait gratitude and social well-being. A sample of 563 undergraduate students was enrolled online and volunteered to participate in this research. According to the purpose of this study, participants were asked to fill in the gratitude and social well-being scales and to fill in the two scales again after a 7-month interval. The cross-lagged path analysis suggested the reciprocal effects between trait gratitude and social well-being. To reduce common method bias, we adopted a daily diary method in study 2. And in this study, 274 young adults completed daily gratitude and social well-being measures once a day for 21 consecutive days. Study 1 showed that trait gratitude at T1 significantly positively predicted social well-being at T2, while social well-being at T1 also significantly predicted trait gratitude at T2 over a long period. After controlling for age and gender, these effects remained significant. Consistent with study 1, study 2 indicated that state gratitude on the previous day could positively predict social well-being (γ = 0.09, SE = 0.03, t = 2.90, p = 0.004) on the next day. Social well-being on the previous day could also positively predict state gratitude (γ = 0.03, SE = 0.01, t = 2.84, p = 0.005) on the next day. Moreover, these relationships were stable after controlling for dates. In conclusion, the result supports the hypotheses. These observations show reciprocal predictive effects between gratitude and social well-being from the longitudinal research and daily diary method. In summary, gratitude is a significant antecedent variable in promoting individual social well-being. Thus, social well-being can be enhanced by gratitude interventions or gratitude education programs. In addition, social well-being also reinforces gratitude, which develops an upward spiral model. The findings of this study further expand the research on the relationship between gratitude and social well-being and provide a new way to improve personal social well-being.

Abstract： Adolescent depresseion and non-suicidal self-injury (NSSI) are major public health concerns worldwide. Identifying the developmental trajectories that lead to these problems can help to design effective prevention programs. Previous research has reported 3 to 6 developmental trajectories of depressed mood and 3 to 4 developmental trajectories of NSSI. However, depressed mood and NSSI often co-occur, and little research has explored their joint developmental trajectories. Importantly, various interpersonal factors may affect the development of both depression and NSSI. For example, research has suggested that adolescents’ relationships with their parents and peers plays a crucial role in developing depression and NSSI. Yet, to date, no research has examined the effect of teacher-student relationships. Therefore, the present study aimed to characterize the joint developmental trajectories of adolescents’ depressed mood and NSSI, and examine the importance of peer, parent and teacher relationships in these trajectories. A sample of 859 adolescents (56.43% males; Mage = 14.73, SD = 0.43) was followed up for three years from the first year to the third year of junior middle school, in a central western Chinese city, Xi’an. Participants reported their depressed mood and NSSI at three time points, one year apart. They also completed self-measures of friendship quality, parent relationships and teacher relationships at Time 1, and nominated their classmates’ peer status at Time 1. All measures were conducted anonymously and approved by school administrators. Latent class growth analysis was used to identify the independent and joint developmental trajectories of depressed mood and NSSI, while logistic regression was used to examine the effects of relations with parents, peers and teachers. We found 4 developmental trajectories of depressed mood and 3 developmental trajectories of NSSI. Moreover, we identified three joint developmental trajectories of adolescents’ depressed mood and NSSI. The first trajectory class (91%), labeled “low depression- low NSSI- stable”, included adolescents with low depression and NSSI across all timepoints. The second trajectory class (5%), labeled “moderate depression-moderate NSSI- decrease”, consisted of adolescents whose depression and NSSI were moderate at baseline and then decrease over time. The third trajectory class (4%) labeled “low depression- low NSSI- increase”, consisted of adolescents whose depression and NSSI were low at baseline and then increase over time. Furthermore, the level of parental psychological control differentiated adolescents in the first joint trajectory class from those in the second and third joint trajectory class. In addition, peer acceptance distinguished adolescents in the third joint trajectory class from those in the first and second joint trajectory class. This study examined the independent and joint developmental trajectories of depressed mood and NSSI during adolescence and revealed important roles of parents and peers in these developmental processes. These findings extend our knowledge of the dynamic relationships between depression and NSSI, and the interpersonal factors that influence this. By improving adolescents’ relationships with their parents and peers, school practitioners can reduce rates of depression and NSSI in this group.
