Electrocutaneous stimulation III. The perception of temporal order

Temporal order thresholds were measured for brief electrical stimuli presented to the forehead and to the abdomen. Temporal acuity is better (thresholds smaller) on the forehead, sensitivity increasing somewhat (thresholds decreasing) as the physical separation between the electrodes increases. Even in that subject, of four, who had the lowest thresholds, however, the value rarely fell below 100 msec. Temporal order thresholds also depend on the orientation, being far smaller when the electrodes are separated horizontally than when separated vertically on both body sites.     

The effect of concordance in the treatment of clients with dental anxiety.

This study followed from an earlier case study in which an agoraphobic client was treated daily for a period of four weeks by in vivo exposure. Ratings of his perceived anxiety responses in the behavioural, cognitive, and physiological systems were monitored throughout treatment. Concordance between these ratings was associated with positive outcome. This study was an attempt to replicate some of these findings. A group programme involving four sessions in which clients were taught anxiety management skills, exposed in imagination to situations relating, to dentistry, and given homework assignments was carried out with clients presenting with disproportionate dental anxiety. The subjects were obtained by means of local newspaper and radio advertisements and randomly assigned to a massed or spaced treatment condition. It was predicted that the massed condition involving shorter intersession intervals would be superior at producing habituation and concordance than the spaced condition. The results failed to show differences between the massed and spaced treatment condition with regard to concordance and outcome. However, it was confirmed, once more, that concordance between the three modes of anxiety responding was positively related to outcome.     

留守学前儿童接受性语言能力与社会退缩的关系:有调节的中介模型

为探讨留守学前儿童接受性语言能力与社会退缩的关系及其内部机制,采用教师评定问卷和测量法对484名留守学前儿童进行调查。结果表明：（1）接受性语言能力不仅对社会退缩具有显著负向预测作用,也能通过执行功能的中介作用负向预测社会退缩;（2）执行功能的中介作用受到师幼关系的调节,相对于高师幼关系水平的个体,间接效应在低师幼关系水平的个体中更为显著,具体而言,师幼关系调节了中介的后半路径;（3）此外,在高师幼关系水平的个体中,执行功能对社会退缩的负向预测作用以及执行功能在接受性语言能力与社会退缩之间的中介作用都不显著。研究结果有助于揭示接受性语言能力对社会退缩的影响及其内在作用机制,对留守学前儿童社会退缩的预防及干预具有一定的启示意义。     

儿童成长型思维干预的理论基础和实践走向

思维模式是人们关于智力是否可塑的内隐信念,是个体内隐意义系统的核心和组织者。个体的思维模式可以分为成长型思维和固定型思维,其中成长型思维有利于儿童学习动机、自我效能和心理韧性的发展。早期的儿童成长型思维干预主要采用面对面的方式,近年来线上的短时程干预得到了快速发展,进而促进了干预的规模化应用,干预的内容也从内隐智力理论拓展到内隐人格理论。对干预效果的评估显示,成长型思维干预能够对儿童学业发展和社会适应产生可持续的促进作用,且对学业困难群体作用更为显著。未来的研究应重视面向对象的干预程序开发,创建有利于成长型思维发展的环境,同时应注意避免实践中的简单化偏差。     

愤怒情绪对恶意创造力的影响及调节策略

以两个实验考察愤怒情绪对恶意创造力表现的影响及作用路径, 并探究调节愤怒情绪对削弱恶意创造力表现的效应。实验1比较愤怒、悲伤、中性情绪下个体恶意创造力表现的差异, 发现愤怒情绪下个体生成更多、更新颖的恶意观点, 情绪唤醒度和内隐攻击性中介了愤怒对恶意创造力表现的影响。实验2探究不同情绪调节策略(认知重评、表达抑制)如何影响愤怒个体的恶意创造力表现, 发现认知重评组和表达抑制组的恶意创造力表现比无策略的控制组水平更低, 情绪唤醒度和内隐攻击性中介了两种情绪调节策略对个体恶意创造力表现的影响。上述结果表明, 愤怒情绪通过提升内隐攻击性和情绪唤醒度进而促进个体恶意创造力表现, 而认知重评和表达抑制策略可作为削弱愤怒个体的恶意创造力表现的有效策略。     

让智慧插上创造的翅膀：创造动力系统的激活及其条件

创造力是一个集个人、团体、社会、文化相互交织的系统, 因此创造力的培养也需要综合考虑。本文在融合以往创造力研究的基础上, 建构了一套系统创造力培养的“蝴蝶理论”, 创造力培养需要抓住核心来统领全局, 同时兼顾创造力培养所需要统筹兼顾的各个部分。动力系统的激活是创造力培养的核心。新颖、适用的创造性成果的产出, 需要社会文化中的个体或团体在创造性心理动力的基础上来完成。创造性心理动力有效的激活则需要一些基本条件, 如在认知层面, 需要具备一定的能力, 如一般认知能力、思维方法的掌握、元认知以及高效的资源整合能力等; 在非智力因素方面, 基本心理需要的满足, 个性心理的健康发展等是创造力得以发挥的必要条件, 推而广之还包括：合理的社会支持、互动以及文化的包容等等。除了理论方面的整合, 本文还从实践的角度分析如何激活学生的动力系统, 重点分析了什么是兴趣以及如何激发个体的兴趣, 因为以兴趣爱好为核心的内部动机是自主性最高的动力来源。本文从理论(创造力培养的蝴蝶理论)与实践(创造力培养的兴趣激发)两个角度为创造力培养提供了支持。     

Understanding The Curvilinear Relationships between LMX Differentiation and Team Coordination and Performance

The leader–member exchange (LMX) literature argues that leaders develop different quality dyadic relationships with members in the same team (i.e., LMX differentiation). Research has generally not found support for a linear (i.e., main effect) relationship between LMX differentiation and team performance; rather, moderators typically determine whether the relationship is significantly positive or negative. Examining linear effect moderators alone, however, does not account for (a) potential curvilinear (i.e., inverted U‐shaped) effects, (b) explanatory mechanisms of how LMX differentiation influences team performance, or (c) moderators of curvilinear effects. Integrating social identity theory with LMX differentiation research, we propose inverted U‐shaped relationships between LMX differentiation and both team coordination (as a mediator) and team performance (as an outcome), and we examine both team size and team power distance orientation as moderators. Using data from 928 employees in 145 teams in 3 organizations, we found an inverted U‐shaped relationship between LMX differentiation and team coordination, which, in turn, partially mediated LMX differentiation's inverted U‐shaped relationship with team performance. Larger teams, or those with higher team power distance orientation, benefit more from LMX differentiation. By integrating social identity theory with LMX differentiation research, we enhance the understanding of the processes by, and conditions under, which LMX differentiation affects team performance both positively and negatively.     

空间书写障碍的个案研究

根据书写加工理论,从异形字水平、图解动作模式水平和神经动作执行水平三个方面,综合考察一例空间书写障碍儿童的认知加工特点。结果表明：（1）个案QY的异形字水平出现选择性损伤,在视觉整体特征的知觉加工上存在困难,导致自发书写的汉字难以辨识,存在严重的间架结构问题。（2）个案QY在图解动作模式水平以及神经动作执行水平上表现正常     

空气污染对个体直接和溢出行为的影响

空气污染对行为影响的研究日渐丰富, 且大致分为两个方向:一是与环境健康有关的直接行为, 二是与之无直接相关的社会行为(溢出行为)。基于此, 在回顾空气污染对两种行为影响研究的同时, 进一步综述了用于解释直接行为产生机制的计划行为理论和健康行动过程取向模型, 以及用于解释社会行为机制的焦虑与自我损耗。而更全面的探究现象背后的机制有助于发现更多有效应对空气污染的举措, 未来的研究可以采用更多纵向的研究范式、增加对行为机制的探究, 从而改善人们的风险应对行为。     

情绪预测偏差的成因及干预

情绪预测偏差是一种对未来事件发生时情绪反应的预测和实际体验之间的分离现象。梳理该领域最近10年(2009~2019年)研究文献可知, 热点研究主题涉及偏差的现象、成因和干预, 相应呈现为三点主要发现: 情绪预测偏差十分普遍, 情绪预测偏差成因多源, 情绪预测偏差可以干预。未来研究应着力关注情绪预测偏差的发生模式和心理机制, 着力揭示具体偏差的神经心理机制, 并从进化和文化视角综合考察偏差的发生机制。
