Family Economic Strain and Adolescent Aggression during the COVID-19 Pandemic: Roles of Interparental Conflict and Parent–Child Conflict

Although the link from family economic strain to adolescent aggression has frequently been hypothesized, the results are mixed. Both interparental conflict and parent–child conflict are considered to be potential mediators of this link. However, the empirical evidence supporting this proposition is lacking. The present study investigated the direct effect of family economic strain on adolescent aggression as well as indirect effects through interparental conflict and parent–child conflict. Based on multi-informant data from 971 families with a child in middle and high schools in Y City, in Shanxi Province, structural equation modeling is conducted to examine the proposed theoretical model. Findings show that family economic strain has no significant direct impact on adolescent aggression. Interparental conflict and parent–child conflict mediate the link between family economic strain and adolescent aggression simultaneously and sequentially. This study expands current literature and deepens our understanding of the mechanisms underlying the relationship between family economic strain and adolescent aggression. Implications for policies and interventions to reduce the risk of adolescent aggression are discussed.

     

人脑自适应多尺度功能连接的性别差异

已有脑成像研究展示了男女脑功能差异, 但功能磁共振信号的频率划分通常基于主观经验, 使脑功能性别差异的生物学解释遭遇瓶颈。本文提出人脑自适应多尺度功能连接算法, 刻画功能连接的时空多尺度特性, 揭示出0.06~0.10 Hz的性别差异：男性较强的连接主要与边缘网络和腹侧注意网络有关, 女性较强的连接主要与腹侧注意网络、视觉网络和额顶网络有关。     

压力知觉对大学生抑郁的影响:有调节的中介模型

本研究采用压力知觉量表、心理韧性量表、领悟社会支持量表和抑郁量表考察压力知觉对大学生抑郁的影响机制,调查了中部地区5所大学746名大一到大四学生。研究显示：（1）心理韧性在压力知觉与大学生抑郁之间起部分中介作用;（2）领悟社会支持调节了这一中介过程,调节了压力知觉对大学生抑郁的影响及压力知觉对心理韧性的影响。可以通过降低大学生的压力知觉水平、提高心理韧性水平和领悟社会支持水平来减少其抑郁。     

不可信面孔在视知觉加工中的注意偏向：来自眼动的证据

使用眼动追踪技术探究个体对同时呈现的可信和不可信面孔的视知觉加工差异, 以及注意偏向与可信和不可信面孔的记忆关系。结果发现：(1)被试再认不可信面孔成绩要好于可信面孔; (2)首注视点更多地偏向于不可信面孔, 并且落在不可信面孔上的总注视时间/注视点个数更长/多; (3)回归分析表明首注视点偏向能预测不可信面孔的再认优势。结果表明人们对不可信面孔产生更多的注意警觉与维持, 并且对不可信面孔的警觉能预测不可信面孔的记忆优势。
