The influence of working memory on the anger superiority effect

The anger superiority effect shows that an angry face is detected more efficiently than a happy face. However, it is still controversial whether attentional allocation to angry faces is a bottom-up process or not. We investigated whether the anger superiority effect is influenced by top-down control, especially working memory (WM). Participants remembered a colour and then searched for differently coloured facial expressions. Just holding the colour information in WM did not modulate the anger superiority effect. However, when increasing the probabilities of trials in which the colour of a target face matched the colour held in WM, participants were inclined to direct attention to the target face regardless of the facial expression. Moreover, the knowledge of high probability of valid trials eliminated the anger superiority effect. These results suggest that the anger superiority effect is modulated by top-down effects of WM, the probability of events and expectancy about these probabilities.     

Effects of modally completed surfaces on change detection

The phenomenon of change blindness suggests that we have a severe capacity limitation in scene perception. The storage of surface representations can overcome this limitation by providing efficient cues about objects in the world. Five experiments examined whether subjective surfaces are preferentially processed in visual short-term memory (VSTM) in a change detection task using a flicker paradigm. Even with the same amount of physical change applied to the figures, people were faster and more accurate in detecting a change involving the presence and absence of a subjective surface than in detecting changes involving subjective contours or rotational symmetry. The effects were not solely due to the configuration of the inducers or to the attentional set. The advantage for the subjective surface reflects the faster encoding into VSTM. Modally completed surfaces play important roles not only in visual perception and search, but also in visual cognition involving VSTM.     

阈下特征框架效应心理机制初探

特征框架效应是指当分别以积极框架和消极框架来描述给定情景中的某一事物或事件的关键特征时,一般情况下人们更偏好以积极框架来描述其关键特征的事物或事件的现象.本研究通过2个实验验证了阈下特征框架效应的存在及其产生机制.实验一发现,阈下特征框架效应只在有时间压力下才会产生.实验二发现,被试对与框架类型一致的词汇判断的反应时比对与框架类型不一致的词汇判断的反应时更快,这在一定程度上说明特征框架效应的产生是因为框架激活了与框架一致性的信息,起到了语义启动的作用,从而导致被试判断任务的评定值偏向该框架类型.     

认知需要和警告类型对合取谬误的影响

合取谬误是一种常见的判断偏差,它指的是在不确定条件下,个体评估合取事件及其简单事件发生的概率时,对合取规则系统性偏离的一种现象.实验1 就认知需要类型对合取谬误的影响进行探讨,结果发现高认知需要的被试较不易表现出双重合取谬误和单合取谬误.实验2 探讨了警告类型对合取谬误的影响,结果发现无警告时个体最易表现出单合取谬误,其次是间接警告,最后是直接警告;此外,认知需要与警告类型的交互作用显著,高认知需要的被试在直接警告和间接警告时更少表现出双重合取谬误,在直接警告时更少表现出单合取谬误.     

The Study of the Development of Civic Engagement Within Contemporary Developmental Science: Theory,Method, and Application

Within contemporary developmental science, models derived from relational developmental systems metatheory emphasize that the basic process involved in the ontogeny of civic engagement involves mutually-influential and beneficial relations between the developing individual and his or her complex and changing social, cultural, and physical contexts (represented as individual ← → context relations). The authors suggest that research on the development of civic engagement should be theoretically predicated, use change-sensitive, longitudinal methods, and be comparative across time and place. Using these facets of scholarship as a lens, we discuss the contributions to this special issue. We conclude that the present set of studies provides a useful basis for future research and applications aimed at understanding and promoting individuals’ civic contributions, and their support of social organizations promoting individual thriving and freedom, liberty, and social justice.     

Mother–Toddler Affect Exchanges and Children's Mastery Behaviours during Preschool Years

This study examined the longitudinal relations of mother–child affect exchanges at 18 months with children's mastery motivation at 39 months. Observation and questionnaire data were collected from mother–child dyads when children were 18 months; 43 mothers again rated their children's mastery motivation at 39 months. Results suggested that after controlling for gender and the corresponding 18‐month mastery aspect, positive affect exchanges had long‐term positive relationships with children's persistence and competence, whereas dismissed affect exchanges had long‐term negative relationships with children's persistence and independent mastery. Findings suggest that children's autonomous mastery‐oriented endeavours have deep roots in their early mother–child affective interactions. Copyright © 2013 John Wiley & Sons, Ltd.     

权重望寡：如何化解低地位领导的补偿性辱虐管理行为?

权力与地位来源不同且体验有别, 二者分离是常态。如果领导者手握权柄却缺乏相应的地位威望, 将限制其控制力, 产生潜在不良后果。基于低地位补偿理论, 构建一个两阶段调节的中介模型, 设计两项研究, 旨在探索领导者“权重望寡” (即权力高, 地位低)所诱发的负面领导行为及其干预机制。研究1揭示: 相对于权力与地位匹配, 领导者权重望寡诱发辱虐管理。研究2探索其成因, 显示: (1)自我损耗中介权重望寡与辱虐管理的关系; (2)领导者正念以及更高层领导信任联合调节自我损耗的中介效应。研究表明, 低地位领导在维护地位过程中产生的自我损耗是引发辱虐管理的主因, 同时辱虐管理强度因人而异, 适可而止, 自身正念和高层信任有助于限制其作为不良补偿手段的蔓延。研究拓展了低地位补偿理论的应用领域, 也为化解权力与地位分离带来的组织冲突提供管理启示。     

原发性失眠患者的主客观睡眠特征研究

目的：了解原发性失眠患者的睡眠特点,探讨其主客观睡眠的异同点。方法：对15例原发性失眠患者、20例正常人的主观睡眠（PSQI）和客观睡眠（PSG）特点进行比较,对原发性失眠患者进行主观睡眠（PSQI）和客观睡眠（PSG）的比较。结果：原发性失眠的PSG多项指标（睡眠总时间、睡后觉醒次数、觉醒总时间、睡眠潜伏期、睡眠效率、觉睡比、睡眠维持率、REM睡眠时间和REM百分比、REM睡眠潜伏期和REM活动密度）等方面与正常对照有显著差异（p〈0.05或p〈0.01）;原发性失眠的PSQI多项指标（PSQI总分、睡眠效率、睡眠时间、睡眠潜伏期）方面与正常组对照差异显著（p〈0.01）。原发性失眠的PSQI和PSG在睡眠效率、实际睡眠时间、睡眠潜伏期方面存在显著差异（p〈0.01）。结论：原发性失眠患者的PSQI和PSG均存在一定程度的异常,原发性失眠患者有高估自己睡眠障碍的倾向。
