高低特质攻击个体对威胁面部表情识别的差异研究——来自ERP的证据

为揭示高特质攻击个体对愤怒、恐惧威胁面部表情识别的特点及其电生理机制，本研究采用Buss-Perry攻击问卷选取高低特质攻击个体26名和27名为被试，采用面孔识别范式对高低特质攻击个体识别威胁面部表情时的ERP差异进行研究。结果发现，在愤怒、恐惧表情上，高特质攻击组在N170成分的潜伏期都显著短于低特质攻击组；在愤怒、恐惧表情上，高特质攻击组在P200成分的波幅都显著高于低特质攻击组。这表明高特质攻击个体对愤怒、恐惧威胁面部表情的识别具有高度敏感性，这种敏感性体现在面部表情识别的早期和中期阶段，而非晚期阶段，即高特质攻击个体在早期的前注意阶段就对愤怒、恐惧威胁面部表情进行优先注意；在中期的注意阶段，高特质攻击个体可以很好地确认愤怒、恐惧威胁面部表情。     

The role of empathy and social anxiety in Latinx adolescents' indirect peer aggression during the transition to high school

The primary purpose of this study was to evaluate the relationship between decreased empathy (i.e., cognitive and affective) and indirect and cyber peer aggression among Latinx adolescents during their transition to high school. Further, we examined the degree to which social anxiety moderated this relationship. Participants were 469 Latinx ninth graders, ages 13–17 years (M = 14.52, SD = 0.58; 58% girls). Adolescents completed the Revised Peer Experiences Questionnaire, Cyber Peer Experiences Questionnaire, Basic Empathy Scale, and Social Anxiety Scale for Adolescents at two different time points, 3 months apart. Hierarchical linear regression analyses revealed concurrent and prospective relationships between lower cognitive empathy and the perpetration of both indirect and cyber aggression. In addition, social anxiety moderated the concurrent associations between both types of empathy and both types of aggression perpetration. Results suggest that interventions that facilitate cognitive empathy and decrease social anxiety may help to reduce adolescents' indirect and cyber aggression toward peers throughout the high school transition.     

Human social defeat and approach–avoidance: Escalating social-evaluative threat and threat of aggression increases social avoidance

Basic research on avoidance by Murray Sidman laid the foundation for advances in the classification, conceptualization and treatment of avoidance in psychological disorders. Contemporary avoidance research is explicitly translational and increasingly focused on how competing appetitive and aversive contingencies influence avoidance. In this laboratory investigation, we examined the effects of escalating social-evaluative threat and threat of social aggression on avoidance of social interactions. During social-defeat learning, 38 adults learned to associate 9 virtual peers with an increasing probability of receiving negative evaluations. Additionally, 1 virtual peer was associated with positive evaluations. Next, in an approach–avoidance task with social-evaluative threat, 1 peer associated with negative evaluations was presented alongside the peer associated with positive evaluations. Approaching peers produced a positive or a probabilistic negative evaluation, while avoiding peers prevented a negative evaluation (and forfeited a positive evaluation). In an approach–avoidance task with social aggression, virtual peers gave and took money away from participants. Escalating social-evaluative threat and aggression increased avoidance, ratings of feeling threatened and threat expectancy and decreased ratings of peer favorableness. These findings underscore the potential of coupling social defeat and approach–avoidance paradigms for translational research on the neurobehavioral mechanisms of social approach–avoidance decision-making and anxiety.     

父母协同教养与学前儿童社会行为的关系:亲子关系和同胞关系的链式中介作用

以河南省某市四所幼儿园大、中、小班共196名学前儿童及其父母和教师为研究对象,基于家庭系统理论,采用父、母填写的父母感知协同教养量表和亲子关系量表、母亲填写的儿童早期同胞关系质量问卷和幼儿教师报告的儿童行为量表探讨亲子关系、同胞关系在父母感知协同教养与学前儿童社会行为之间的中介作用。结果发现：（1）母子冲突和母子亲密分别在母亲感知协同教养与同胞冲突和同胞温暖间起部分中介作用;父子冲突和父子亲密分别在父亲感知协同教养与同胞冲突和同胞温暖间起完全中介作用;（2）父/母子冲突和同胞冲突在母亲感知协同教养和儿童攻击行为间起链式中介作用;父子冲突和同胞冲突在父亲感知协同教养和儿童攻击行为间起链式中介作用。     

The mediation effect of emotion dysregulation in the relationship between anger and aggression on the road in a sample of Spanish drivers

Aggressive behaviour on the road is one of the most studied topics in human factors, given it has been related to both risky behaviour and traffic crashes. While previous research has proposed trait driving anger as one of the better predictors, mediation variables which could explain this relationship have not deserved attention. The current research aimed to explore the mediation effect of emotion regulation in this relationship. The sample consisted of 472 Spanish drivers, who completed a set of self-reports regarding trait driving anger, frequency of aggressive behaviours at the wheel, and difficulties in emotion regulation. The results showed significant relationship among the variables in almost all the cases. Furthermore, a SEM analysis showed that difficulties in emotion regulation significantly mediated the relationship between trait driving anger and each way of the aggressive behaviours (verbal, physical, using own vehicle, and displaced). These results have important implications in the design of strategies focused on the improvement of emotion regulation to reduce aggressive behaviours in drivers. Finally, the limitations of the study are commented.     

刷微博，让焦虑的人更焦虑——特质焦虑对青少年注意情绪刺激的影响

采用自由观看眼动追踪范式,考察特质焦虑青少年在观看情绪面孔图片过程中的眼动轨迹。结果发现,高特质焦虑组对愤怒和恐惧面孔的首次注视到达时间（TFF）较快,首次注视持续时间（TFD）较短;低特质焦虑组对愤怒和恐惧面孔的TFF虽然稍早于平静面孔,但差异不显著。在刺激呈现1000ms之后,高特质焦虑组对愤怒和恐惧面孔的注视次数（FC）较多,平均注视持续时间（AFD）较短。低特质焦虑组对愤怒和恐惧面孔的FC较少,AFD较长;这就表明,高特质焦虑青少年在认知加工早期对威胁性刺激注意定向加速,没有注意解除困难,呈现“浅尝辄止”现象。而在认知加工晚期,他们则对威胁性刺激存在“反刍”现象。     

特质感恩与状态感恩对初中生合作水平的影响

为探究感恩对初中生合作水平的影响,本研究采用追踪调查与实验相结合的方法,通过两个研究分别探究了特质感恩与内在的合作倾向,状态感恩与外在的合作行为之间的关系。结果发现：（1）初中女生的特质感恩、人物取向感恩显著高于男生;初一下的合作倾向显著低于初一上、初二上时期;（2）初中生的特质感恩水平能显著正向预测合作倾向,状态感恩的唤起会增加公共物品困境中的合作行为。     

特质自我控制个体在多源干扰任务下的认知神经机制

本研究采用事件相关电位技术(ERPs)结合多源干扰任务(MSIT)范式来探讨特质自我控制个体的认知神经机制。考察了高、低自我控制者各26名在MSIT任务上的差异。结果：高自我控制者的反应时显著长于低自我控制者。在MSIT冲突条件下,高自我控制者的N2和P3(LPC)波幅比无冲突条件更大。结论：高自我控制者较低自我控制者处理冲突干扰更慢,需要的注意资源较多,激活前额叶中部脑区。     

四周简易正念减压训练对初中生焦虑的影响

选取68名初一学生并以班级为单位分为四周正念减压(mindfulness-based stress reduction,MBSR)训练组和对照组,探讨四周MBSR对初中生焦虑和正念水平的影响,以及训练效果是否存在基线效应与性别差异。结果发现:(1)四周MBSR可以提高初中生的正念水平,缓解其焦虑情况;(2)“不判断”和“特质焦虑”基线水平影响正念训练的效果;(3)四周MBSR对初中生的训练效果不存在性别差异。
