The selective use of punishments on congruent versus incongruent trials in the Stroop task.

Conflict adaptation refers to the dynamic modulation of conflict processing across successive trials and reflects improved cognitive control. Interestingly, aversive motivation can increase conflict adaptation, although it remains unclear through which process this modulation occurs because previous studies presented punishment feedback following suboptimal performance on both congruent and incongruent trials. According to integrative accounts of conflict monitoring and aversive motivation in the dorsal anterior cingulate cortex, punishment feedback following slow or erroneous performance on incongruent trials in particular should lead to improved conflict adaptation. Second, selectively increasing motivation on incongruent trials should reduce the overall congruency effect. The current study sought to test both hypotheses. Specifically, we administered the confound-minimized Stroop task to a large group of participants and manipulated the position of feedback (following either congruent or incongruent trials) and aversive motivation (tied to a monetary loss or not) across different blocks. As expected, the congruency effect was found to be smaller when punishment was coupled with incongruent versus congruent trials. However, results showed that conflict adaptation was increased when punishment feedback was selectively coupled with congruent rather than incongruent trials. Together, these results suggest that aversive motivation does not uniformly improve cognitive control but this gain appears to be context dependent.

Two sources of autonomy support and depressive symptoms among Chinese gay men: The sequential mediating effect of internalized homonegativity and rumination.

BACKGROUND: A high level of depressive symptoms is a universal phenomenon among gay groups. Autonomy support, which refers to supporting an opportunity for others to authentically express themselves and behave consistently with their own beliefs, values and interests, is considered a critical protective factor facilitating the relief of depressive symptoms in gay men. The aim of the current study was to examine the relationships between two sources of autonomy support (from parents and friends) and depressive symptoms in a Chinese context and evaluate the mediating effects of internalized homonegativity and rumination. METHODS: Altogether, 385 Chinese gay men (mean age = 24.00 years old, standard deviation (SD) = 4.84) who were voluntarily recruited by web-sampling were measured on scales regarding autonomy support, internalized homonegativity, rumination and depressive symptoms. RESULTS: Autonomy support from both parents and friends were negatively correlated with depressive symptoms among Chinese gay men. Internalized homonegativity and rumination played a sequential mediating role between friends' autonomy support and depressive symptoms, yet this sequential mediation effect was not significant between parental autonomy support and depressive symptoms. LIMITATIONS: The cross-sectional design limited casual inferences between variables. The effects of domain-specific autonomy support were not involved in this study, and other mediators between autonomy support and depressive symptoms and more sociodemographic variables should be considered. CONCLUSION: Autonomy support from both parents and friends might be protective factors against depressive symptoms in Chinese gay men. Friends' autonomy support was related to decreased depressive symptoms via lower internalized homonegativity and rumination, while parental autonomy support was related to less depressive symptoms through other possible mechanisms.

Exposure to Community Violence, Affiliations With Risk-Taking Peer Groups, and Internet Gaming Disorder Among Chinese Adolescents: The Moderating Role of Parental Monitoring.

Among adolescents, exposure to community violence (ECV) has been consistently linked to problem behaviors such as Internet gaming disorder (IGD). However, the associated risk and protective factors have not been adequately explored in past studies. Therefore, in accordance with the risk-buffering model and social development model, this study aimed to test whether parental monitoring moderated the relationship between ECV and IGD among adolescents, and whether this moderating effect was mediated by affiliations with risk-taking peer groups. A sample of 2,423 Chinese middle-school students anonymously responded to questionnaires that assessed ECV, IGD, affiliations with risk-taking peer groups, and parental monitoring. The results of structural equation modeling revealed that the interaction between ECV and parental monitoring negatively related to IGD among adolescents. Specifically, the positive relationship between ECV and IGD was stronger for adolescents, who reported low levels of parental monitoring than for those who reported high levels of parental monitoring. Moreover, this moderating effect was mediated by affiliations with risk-taking peer groups. These results suggest that parental monitoring is an important protective factor that can mitigate the risk of IGD among adolescents who have been exposed to community violence. Accordingly, these findings serve as an empirical base upon which prevention and intervention strategies that are aimed at mitigating the risk of IGD among adolescents can be developed.
