Social networking site;Selfie-posting;Self-objectification;Commentary on appearance;Restrained eating
摘要：
Considering the prevalence of social networking sites (SNSs) and restrained eating among young adult women, the present study aimed to investigate the association between selfie-posting on an SNS (WeChat Moments, the most widely used SNS in China) and self-objectification among Chinese young adult women as well as the mediating effects of commentary on appearance and self-objectification from the perspective of self-perception theory and objectification theory. A sample of 886 female undergraduate students who had an active WeChat Moments account were recruited voluntarily to complete questionnaires on selfie-posting on SNS, general SNS use, commentary on appearance on SNSs, self-objectification, and restrained eating. The results indicated that after controlling for general SNS use, age, and BMI, selfie-posting on a SNS was positively associated with restrained eating. Commentary on appearance and self-objectification mediated this association, which contained three mediating paths: the separate mediating effects of commentary on appearance and self-objectification and the serial mediating effect of commentary on appearance and self-objectification. These results indicate that selfie-posting and commentary on appearance on a SNS rather than general SNS use are risk factors accounting for restrained eating, which has theoretical and practical implications in terms of SNS use and restrained eating.

Boredom proneness;Depression;Problematic mobile phone use;Attentional control
摘要：
Background: Boredom proneness has been demonstrated as a salient vulnerability factor for problematic mobile phone use. However, the mediating and moderating mechanisms underlying this relationship are less investigated. In the current study, we constructed an integrative moderated mediation model to test the mediating role of depression and the moderating role of attentional control in the relationship between boredom proneness and problematic mobile phone use. Method: A total of 1099 college students (M-age = 20.04; SD = 1.25) were recruited to fill out the questionnaires measuring boredom proneness, depression, problematic mobile phone use, and attentional control. Results: Depression partially mediated the relationship between boredom proneness and problematic mobile phone use. Attentional control moderated the indirect relationship between boredom proneness and problematic mobile phone use through depression, with the indirect relationship being weaker for college students with higher levels of attentional control. Moreover, attentional control moderated the direct relationship between boredom proneness and problematic mobile phone use, in that this relationship was stronger for college students with higher levels of attentional control. Conclusions: These findings illuminate the pathway through which boredom proneness is linked to problematic mobile phone use (i.e., mediation) and the condition on which the relationship between boredom proneness and problematic mobile phone use depends (i.e., moderation). More importantly, this study revealed the potential "double-edged sword" effect of attentional control. These findings have implications for early intervention and prevention of problematic mobile phone use in college students.

摘要：
Based on compensatory satisfaction theory, the present study examined the relation between body dissatisfaction and adolescent smartphone addiction, as well as the roles of positive self-presentation on social networking sites and friendship quality. A sample of 1036 Chinese adolescents from 11 to 15 years of age (mean age = 12.41 years, SD = 0.65) responded to anonymous questionnaires regarding body dissatisfaction, friendship quality, positive self-presentation on social networking sites and smartphone addiction. The results indicated that body dissatisfaction could positively predict adolescent smartphone addiction. In addition, positive self-presentation on social networking sites mediated the relation between body dissatisfaction and smartphone addiction. Moreover, the first part of the mediating effect (i.e., the link from body dissatisfaction to positive self-presentation on social networking sites) was moderated by friendship quality, with the effect being significant only for adolescents with low levels of friendship quality. The present study can advance our understanding about smartphone addiction and how human interact with technology. Limitations and implication about the present study are also discussed.

摘要：
The present study examined whether individuals experienced the same cognitive advantage for online self-relevant information (nickname) as that experienced for information encountered in real life (real name) through two experiments at both the behavioural and neural levels (event-related potential, ERP). The results indicated that individuals showed the same cognitive advantage for nicknames and real names. At the behavioural level, a nickname was detected as quickly as the real name, and both were detected faster than a famous name; at the neural level, the P300 potential elicited by one's nickname was similar to that elicited by one's real name, and both the P300 amplitudes and latencies were larger and more prolonged than those elicited by other name stimuli. These results not only confirmed the cognitive advantage for one's own nickname and indicated that this self-advantage can be extended to online information, but also indicated that the virtual self could be integrated into the self and further expanded individuals' self-concept.
摘要：
Although cyberbullying, a new type of aggressive behavior via electronic means, has been found to be strongly linked with individuals' personality characteristics, few studies to date have investigated its relationship with narcissism, especially overt and covert narcissism. The current study tested the associations between overt and covert narcissism on one hand and cyberbullying perpetration and victimization on the other. To explain these differences further, self-esteem was tested as a mediator through which the two types of narcissism may exert their influences on cyberbullying. An anonymous questionnaire was completed by 814 Chinese adolescents aged 11 to 18. Results of multiple regression analyses indicated that after controlling for gender and student status (middle or high school students), covert narcissism positively predicted both cyberbullying perpetration and victimization, whereas overt narcissism had no association with either perpetration or victimization. Furthermore, when gender and student status were controlled, self-esteem mediated the relationships between overt/covert narcissism and cyberbullying perpetration and victimization, highlighting the possibility that self-esteem is an explanatory mechanism for the associations between the two types of narcissism and cyberbullying. These findings suggest that interventions aimed at reducing engagement in cyberbullying may be more urgent and important for individuals with high levels of covert narcissism. Boosting self-esteem needs to be particularly highlighted in developing anti-bullying measures and policies.
