Previous research has shown that 3-month-olds prefer own- over other-race faces. The current study used eye-tracking methodology to examine how this visual preference develops with age beyond 3 months and how infants differentially scan between own- and other-race faces when presented simultaneously. We showed own- versus other-race face pairs to 3-, 6-, and 9-month-old Chinese infants. In contrast with 3-month-olds' visual preference for own-race faces, 9-month-olds preferentially looked more at other-race faces. Analyses of eye-tracking data revealed that Chinese infants processed own- and other-race faces differentially. These findings shed important light on the role of visual experience in the development of visual preference and its relation to perceptual narrowing.

This study investigated the mental health status of medical students in China, and analyzed the influencing factors in order to provide evidence for mental health education for medical students. A stratified cluster sampling method was used to recruit medical students from Huazhong University of Science and Technology, China. The questionnaire survey on general information and Symptom Checklist 90 (SCL-90) were used for investigation and analysis. The results showed among the 1137 valid questionnaires, 278 (24.45%) participants had SCL-90 score ≥ 160. The top three mental problems of medical students were obsessive-compulsive disorder, interpersonal sensitivity and depression in terms of the factor score ≥ 2.5 and the number of participants who reflected on the diseases. The third-year medical students had the worst mental health status, and fifth-year medical students had the best mental health status. Students from rural area had more psychological problems than those from urban area; furthermore, students with high professional satisfaction, those who were the single child of the family, non-poor students, and those whose parents had high education level had better mental health status. It was concluded that the mental health of medical students is not optimistic in China. Medical students have some mental health problems of different degrees. Factors that influence the mental health of medical students include academic pressure, professional satisfaction level and family environment.

PurposeDrawing on self-determination theory, this study explored how leader humility affected employees' proactive behavior through satisfying their psychological needs for autonomy, competence and relatedness. Furthermore, based on a contingency view, this paper suggested Chinese traditionality as a significant boundary condition for the effects of leader humility.Design/methodology/approachData were collected from 465 employees and 111 direct supervisors in China using a three-wave, two-source design. Hierarchical regression analyses and Hayes' PROCESS macro were applied to test the hypotheses.FindingsThe results indicated that leader humility positively affected employee proactive behavior through the mediating mechanisms of psychological need satisfaction (i.e. autonomy, competence and relatedness). Furthermore, these positive effects were stronger among employees with lower Chinese traditionality beliefs.Originality/valueAlthough prior research has examined the relationship between leadership and proactive behavior, most extant studies have focused on “top-down” leadership approaches, ignoring the effect of leader humility. Drawing on self-determination theory, the present study makes contributions to both the leader humility research and proactivity literature by identifying psychological need satisfaction as the mechanism and Chinese traditionality as the moderator.

The current study aims to clarify the longitudinal relations among parent emotion regulation (ER), child ER, and children’s oppositional defiant disorder (ODD) symptoms. In the current study, parents of 275 children (195 boys, 70.1%) with ODD symptoms ( Mage = 9.32 years, SD = 1.64) reported their ER using the Difficulties in Emotion Regulation Scale, child ERs using the Emotion Regulation Checklist, and children’s ODD symptoms using the eight symptoms indicated in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) at three time points (T1, T2, and T3) within 2 years. Results indicated the longitudinal relationships between parent ER and children’s ODD symptoms were directly influenced by each other. Children’s ODD symptoms had important effects on both child ER and parent ER. Findings suggested that to reduce children’s ODD symptoms, it is necessary not only to improve child ER but also to improve parent ER.
