不同睡眠时间参数对学前儿童执行功能的差异化影响

研究选取78名5~7岁的学前儿童为研究对象, 采用睡眠日志法测量了儿童的夜间睡眠比、总睡眠时长和周末补偿睡眠三个睡眠时间的指标, 同时采用母亲报告法收集儿童的消极情绪性, 3个月后采用美国国立卫生研究院(NIH)的一套标准化测量程序评估儿童的执行功能, 探讨三个睡眠时间参数对不同消极情绪性学前儿童执行功能的差异化影响。结果发现, 在控制了儿童的同时性语言能力之后, 夜间睡眠比能够显著预测儿童三个月之后的执行功能; 儿童的消极情绪性与周末补偿睡眠对执行功能的三个子成分存在显著的交互作用。当周末补偿睡眠较少时, 高消极情绪性儿童的执行功能显著低于低消极情绪性儿童; 当周末补偿睡眠较多时, 高消极情绪性儿童的执行功能显著高于低消极情绪性儿童, 该结果符合差别易感性模型。     

The reducing effect of positive imagined intergroup contact on intergroup attributional bias

Currently, the Han and Uygur ethnicities in Xinjiang, China are generally in a peaceful state; however, there are also disagreements and conflicts. Through three studies, this article explores intergroup attributional bias (in‐group favoring and out‐group derogating pattern of attribution) between the Hans and Uygurs in Xinjiang, China, and the reducing effect of positive imagined intergroup contact on intergroup attributional bias. Using high school students from Han and Uygur as participants, Study 1 investigated participants’ attributional patterns for in‐group and out‐group members presenting desirable or undesirable behaviors in daily situations. The results revealed that both Hans and Uygurs demonstrate an in‐group favoring pattern of attribution, but not an out‐group derogating pattern. Study 2 added a brief positive imagined intergroup contact (experimental group) or a brief positive imagination of an outdoor scene (control group) before participants completed the same questionnaire as in Study 1 and found a weaker intergroup attributional bias in the experimental group. In Study 3, Han students who had a positive imagined contact with a Uygur demonstrated a closer distance and reported more positive attitudes toward Uygurs than Han students who had imagined contact with a nonspecific stranger. Studies 2 and 3 together indicated a reducing effect of imagined contact on intergroup attributional bias through improvement of intergroup attitudes. The conclusion of this research is particularly meaningful for the Hans and Uygurs, as it implies that properly implemented positive imagined intergroup contacts might be a useful remedy for reducing potential conflicts.

5—7岁儿童加法策略的发展特点

随机选取72名5～7岁儿童为被试,采用实验法和访谈法对儿童解决简单加法问题的策略的发展特点进行探索。结果发现,随着年龄的增长,儿童使用提取策略明显上升,逐渐成为主导策略,而数数策略逐渐减少,凑十策略、心理算盘策略和分解策略只有在少数儿童身上发现,整体看5～7岁儿童没有出现多种策略的竞争趋势;提取和从大数开始数的策略是5～7岁儿童较为优秀的解决简单加法问题的策略。     

论阿多诺视域中的一段现象学公案

同一段现象学描述,在胡塞尔那里意味着同一性和直接性,而阿多诺却从中发现了非同一性、中介性、缺席性、他者性和剩余性这些与后现代思想相关的特质。但是,互文性的分析表明,这些特质的首倡者恰恰不是阿多诺而是胡塞尔。阿多诺的分析与批驳,胡塞尔的凸现与“辩护”,恰恰透露了辩证法与现象学的不同旨趣。     

汉字识别中亚词汇语音和语义信息在N170上的神经适应

视觉词汇识别的事件相关电位(ERP)研究发现早期的脑电成分N170具有对词汇的敏感性, 可能反映了字形、语音和语义加工, 目前还没有得到统一的结论。本研究利用汉字形声字声旁表音和形旁表义的独特性, 使用神经适应范式深入考察了N170对汉字亚词汇语音和语义信息的敏感性。实验1操纵了连续汉字的声旁和整字读音重复呈现探究其诱发的神经适应性, 结果发现了左侧电极的N170对声旁和整字读音重复都产生了神经适应。实验2进一步操纵形旁和整字语义的重复呈现, 结果发现左侧N170仅对整字语义相似性具有神经适应性, 而右侧N170对形旁和整字语义重复都产生了神经适应。实验结果表明, 左侧N170不仅对整字语音和语义信息敏感, 还对亚词汇的声旁信息敏感; 而右侧N170对整字语义以及亚词汇的形旁信息敏感。     

认知行为疗法在儿童社会退缩行为干预中的新进展

社会退缩行为指儿童在社会情境中抑制自己参与同伴互动并表现出独处的行为。社会退缩阻碍儿童形成良好的社交能力,影响其人格和认知的健康发展,因而对儿童社会退缩行为进行及时干预显得十分重要。研究对认知行为疗法在儿童社会退缩行为干预中的进展进行了整合,包括虚拟现实暴露疗法、学校情境下的认知行为治疗及网络认知行为治疗。未来研究应设计针对社会退缩行为不同亚类型的干预方案,以及在干预中重视情绪调节的训练和教师的介入。     

攻击动机对特质愤怒与反应性攻击关系的中介作用：一项纵向研究

特质愤怒是影响反应性攻击的重要人格因素, 反应性攻击的提出是基于攻击动机, 但是特质愤怒影响反应性攻击的动机机制尚不清楚。本研究假设特质愤怒可以通过增强反应性攻击的特异性动机(即敌意性动机)以及反应性攻击与主动性攻击的共同性动机(即道德准许动机)来纵向预测反应性攻击。为了检验该假设, 对5个省市共1007名大学生的特质愤怒、敌意归因偏向(代表敌意性动机)和道德推脱(代表道德准许动机)、反应性攻击与主动性攻击进行了3次追踪调查。结果显示：(1)在控制性别后, 第一个时间点的特质愤怒可以通过第二个时间点的敌意归因偏向和道德推脱预测第三个时间点的反应性攻击; (2)敌意归因偏向只能纵向预测反应性攻击, 而不能跨时间预测主动性攻击; (3)道德推脱可以纵向预测反应性攻击和主动性攻击。这一结果支持了特质愤怒影响反应性攻击的动机模型, 发展了人格与攻击关系的理论与研究, 对于揭示反应性攻击形成的动机机制具有积极作用。     

Work–family conflicts,cognitive appraisal,and burnout: Testing the mediation effect with structural equation modelling

Work–family conflict constitutes an important source of occupational stress predicting teachers’ burnout, and cognitive variables have shown to be core structures in explaining human adaptation to stress. Nevertheless, the role of cognitive appraisal needs to be fully analysed to comprehend how it can mediate the relationship between stress and burnout. In order to understand the potential mediation of cognitive appraisal in the relationship between stress and burnout, we adopted conceptual models of stress that highlighted the value of cognitive appraisal on positive and negative reactions to work demands. Also, we analysed the potential moderation of sex and age in the relationship between work–family conflict, cognitive appraisal, and burnout due to inconsistent findings on how these personal variables can interfere on these relations. In this study, we used structural equation modelling (SEM) to test the mediating of cognitive appraisal in the relationship between work–family conflicts and burnout. A survey with measures of work–family conflicts, cognitive appraisal, and burnout was administered to the participants consisting of 438 Portuguese teachers from kindergarten through high school, aged between 28 and 67 years (M = 46.85; SD = 7.88), 304 of whom were females (69.41%). The results confirmed that cognitive appraisal partially mediated the relationship between work–family conflict and burnout. The mediation effect of cognitive appraisal on the relationship between work–family conflict and burnout was invariant regardless of teachers’ sex or age. In sum, cognitive appraisal should be considered in order to understand teachers’ adaptation to work.     

Self-esteem and hope mediate the relations between social support and post-traumatic stress disorder and growth in adolescents following the Ya’an earthquake

Background and objective: Although posttraumatic stress disorders (PTSD) and posttraumatic growth (PTG) can co-exist, and several theories suggest that social support, self-esteem, and hope can predict both PTSD and PTG, no study to date has examined the combined role of social support, self-esteem, and hope in PTSD and PTG. The present study aimed to simultaneously examine the mediating roles of self-esteem and hope in the relations between social support and PTSD, and between social support and PTG.

Design: This study included 397 adolescents living in Lushan County, China, who were affected by the Ya’an earthquake.

Method: The participants completed the self-report questionnaires at two and a half years after the earthquake. Structural equation models were built to examine the roles of social support, self-esteem, and hope in PTSD and PTG.

Results: Social support directly and negatively predicted PTSD and positively predicted PTG. Moreover, social support negatively predicted PTSD via self-esteem, and positively predicted PTG via hope. In addition, social support positively predicted PTG through multiple mediating paths from self-esteem to hope.

Conclusions: PTSD and PTG had different predictive paths. Specifically, social support reduced PTSD through enhanced self-esteem and promoted PTG through hope, or through the path from self-esteem to hope.
