工作记忆容量对创造性思维的预测

创造性思维(CT)是人类高级认知的重要组成部分,而工作记忆容量(WMC)是个体认知功能的重要指标,对于WMC能否预测CT存在不同的观点。本文先从正向预测、负向预测和不能预测的角度分类总结了相关研究证据,然后用游乐园模型(APT)、双通道模型(DPCM)和注意控制理论(CAT)对不同结果进行解释,分析了以往研究可能存在的问题,包括测量WMC和测量CT的任务类型不匹配、测量CT的领域特殊性问题、忽略其他认知能力差异以及未考虑智力、人格等因素对二者关系的影响等。最后,结合已有问题与当前的研究重点对未来研究进行了相应的展望。     

儿童自我控制心理机制的理论述评

自我控制是个体抑制和调节自身冲动的能力,是个体适应社会的主要标志。对自我控制心理机制的探讨在此领域的研究中居于核心地位。在精神分析理论、认知发展理论和行为主义理论早期观点的基础上,A.Gifford、W.Mischel和J.kuhl等人在近期研究中分别强调了情绪、认知和注意过程以及自我调节策略在个体自我控制过程中的作用,在此基础上,该文总结了关于自我控制心理机制研究中较为一致的结论和仍然存在的分歧。     

核心自我评价研究的反思与展望

核心自我评价是一种潜在的、宽泛的人格结构, 被定义为个体对自我能力和价值所持有的最基本的评价和估计。在过去十余年里, 核心自我评价的研究重点从早期关注结构的验证与测量、探讨核心自我评价在工作领域中的功能, 到近期开始转向探讨与心理健康、学业行为等变量的关系。另外, 核心自我评价的预测作用和调节作用可从动机、图式、能力、应对与获益和自我验证五种机制进行解释。核心自我评价的起源、过高核心自我评价是好是坏、核心自我评价还应包括或排除哪些因素、核心自我评价是否只有高低之分、“参照框架”对核心自我评价的预测力有何影响等涉及核心自我评价性质的问题目前仍没有得到解决。未来的研究可着眼于扩大研究领域、解决与核心自我评价性质有关的问题以及对核心自我评价进行本土化研究。     

大学生的三重自我建构与个人自主的关系

采用问卷法,以477名本科学生为被试,探讨大学生的三重自我建构与个人自主水平之间的关系。结果显示:(1)个体自我可显著负向预测外部调控,正向预测认同调控和整合调控。(2)关系自我可显著正向预测外部调控和投射调控,且可在个体自我与外部调控、认同调控的关系中起调节作用。(3)集体自我可显著负向预测外部调控,正向预测投射调控、认同调控和整合调控,且可在个体自我与投射调控的关系中起调节作用。研究支持了个体自我的积极作用,同时也揭示了关系自我和集体自我对个人自主产生积极作用的方式。     

任务数量与工作记忆容量对交错学习的影响

研究以分子结构式为材料,让被试在单任务或双任务条件下以集中呈现和交错呈现的方式进行学习,并通过操作广度、旋转广度和对称广度任务测量工作记忆容量（working memory capacity, WMC）,探究在基于规则类别学习中交错呈现优势的稳定性。结果显示,交错呈现优势仅体现在文科生中;而对于理科生,集中呈现效果较佳。另外,任务数量和WMC均不影响交错呈现优势,表明交错呈现优势稳定存在于单任务和双任务条件中,且不同WMC的个体均能从交错学习获益。     

从动作模仿到社会认知：自我-他人控制的作用

在社会互动中, 人们具有自动模仿他人动作的倾向。尽管这种自动模仿有利于个体理解他人动作的感受, 但有时也会与自身的动作意图产生冲突。因此我们需要将自身动作意图与他人动作进行区分并调控二者之间的冲突。这种能力被称为自我-他人控制(self-other control, SOC)。与动作模仿控制相同, 心理理论、观点采择和共情等更高级的社会认知同样涉及对自我和他人信息的加工。很多证据表明, SOC可能是一种领域普遍的(domain-general)加工机制, 即在动作模仿控制和其他社会认知中, 大脑对自我和他人双方信息的区分和冲突调控共用同一套SOC系统。最近一些研究发现, 相比于抑制自身优势反应的抑制控制(inhibitory control), SOC是社会认知中一个更为关键的影响因素, 抑制控制对社会认知的作用受到SOC的调节。此外, SOC的领域普遍性提示我们, 未来可以通过简单的动作模仿控制训练, 来为社会认知受损个体(如孤独症和述情障碍者)进行康复训练。     

自我调控学习:研究背景、方法发展与未来展望

自我调控学习(self-regulated leaming,SRL)是学生学习成功的终极问题.本文重点考察了自我调控学习的第二次研究浪潮,即有关即时测量自我调控过程研究方法的发展,如利用电脑跟踪、有声思维口头报告法、学生学习的结构化日记和微观的周期模型分析法,利用这些自我调控法,能够体现自我调控干预培训的有效性.虽然这些即时事件测量的方法仍处于雏形发展阶段,但对于自我调控学习的因果推论提供了宝贵的信息资料.本文还对今后相关重点课题和研究方法指明了方向.

经皮迷走神经刺激对抑制控制的调节机制

近年众多研究表明, 经皮迷走神经刺激(tVNS)作为一种新型、非侵入式的神经调控技术对个体的抑制控制功能具有积极的调节作用。已有研究发现, tVNS对抑制控制的调节作用可能是通过调控蓝斑核-去甲肾上腺素系统(LC-NE)的活动和神经递质GABA的浓度来实现的。然而, 目前对tVNS调控抑制控制的神经机制仍存在诸多尚未明确的问题。未来研究在进一步优化tVNS的刺激参数后, 可以从tVNS对抑制控制能力受损群体的调控作用及机制、如何实现和增强tVNS长期积极效应等方面进行深入探索。     

多巴胺D2受体参与调节感觉门控的机制

精神分裂症是一种常见的病因不明的精神疾病。大量文献表明精神分裂症患者所表现出来的认知紊乱和思维异常等症状与感觉门控功能的缺失有密切的关系, 感觉门控是指在充满刺激的环境中, 从外界的感觉信息中过滤无关的感觉信息然后执行与注意力相关的认知过程, 以对显著的刺激做出反应。研究感觉门控的经典范式是震惊反射的前脉冲抑制。研究发现多巴胺D₂受体可以参与调控前脉冲抑制的过程, 但是多巴胺D₂受体参与调控前脉冲抑制的机制仍不清楚。探讨多巴胺D₂受体参与调控感觉门控即前脉冲抑制的关键脑区、神经环路及分子机制, 有利于促进对精神分裂症感觉门控功能的深入研究。     

Executive functions and self-regulation

Self-regulation is a core aspect of adaptive human behavior that has been studied, largely in parallel, through the lenses of social and personality psychology as well as cognitive psychology. Here, we argue for more communication between these disciplines and highlight recent research that speaks to their connection. We outline how basic facets of executive functioning (working memory operations, behavioral inhibition, and task-switching) may subserve successful self-regulation. We also argue that temporary reductions in executive functions underlie many of the situational risk factors identified in the social psychological research on self-regulation and review recent evidence that the training of executive functions holds significant potential for improving poor self-regulation in problem populations.     

Individual differences in working memory capacity and dual-process theories of the mind

Dual-process theories of the mind are ubiquitous in psychology. A central principle of these theories is that behavior is determined by the interplay of automatic and controlled processing. In this article, the authors examine individual differences in the capacity to control attention as a major contributor to differences in working memory capacity (WMC). The authors discuss the enormous implications of this individual difference for a host of dual-process theories in social, personality, cognitive, and clinical psychology. In addition, the authors propose several new areas of investigation that derive directly from applying the concept of WMC to dual-process theories of the mind.     

Need for closure and dealing with uncertainty in decision making context: The role of the behavioral inhibition system and working memory capacity

The aim of the present study was to investigate the moderated mediation model of the relationship between the behavioral inhibition system (BIS), need for closure (NFC) and working memory capacity (WMC) in the decision making process. It was assumed that NFC works as a motivational mechanism that enables individuals high in BIS to deal with uncertainty; therefore, NFC mediates the effect of BIS on behavior in a decision-making situation. Moreover, as uncertainty management requires cognitive resources, we expected WMC to moderate this relationship. In line with our hypothesis, we found that NFC mediated the relationship between BIS and the information search about the job candidates, and this effect occurred only for individuals high in WMC. We discuss these results in the context of effective self-regulation, as well as motivational and cognitive determinants of effort.     

Working memory capacity and spontaneous emotion regulation: high capacity predicts self-enhancement in response to negative feedback

Although previous evidence suggests that working memory capacity (WMC) is important for success at emotion regulation, that evidence may reveal simply that people with higher WMC follow instructions better than those with lower WMC. The present study tested the hypothesis that people with higher WMC more effectively engage in spontaneous emotion regulation following negative feedback, relative to those with lower WMC. Participants were randomly assigned to receive either no feedback or negative feedback about their emotional intelligence. They then completed a disguised measure of self-enhancement and a self-report measure of affect. Experimental condition and WMC interacted such that higher WMC predicted more self-enhancement and less negative affect following negative feedback. This research provides novel insight into the consequences of individual differences in WMC and illustrates that cognitive capacity may facilitate the spontaneous self-regulation of emotion.     

Social action theory for a public health psychology

Many illnesses can be prevented or limited by altering personal behavior, and public health planners have turned to psychology for guidance in fostering self-protective activity. A social theory of personal action provides an integrative framework for applying psychology to public health, disclosing gaps in our current understanding of self-regulation, and generating guidelines for improving health promotion at the population level. A social action view emphasizes social interdependence and interaction in personal control of health-endangering behavior and proposes mechanisms by which environmental structures influence cognitive action schemas, self-goals, and problem-solving activities critical to sustained behavioral change. Social action theory clarifies relationships between social and personal empowerment and helps explain stages of self-change.     

High working memory capacity does not always attenuate distraction: Bayesian evidence in support of the null hypothesis

Individual differences in working memory capacity (WMC) predict individual differences in basically all tasks that demand some form of cognitive labor, especially if the persons conducting the task are exposed to distraction. As such, tasks that measure WMC are very useful tools in individual-differences research. However, the predictive power of those tasks, combined with conventional statistical tools that cannot support the null hypothesis, also makes it difficult to study the limits of that power. In this article, we review studies that have failed to find a relationship between WMC and effects of auditory distraction on visual–verbal cognitive performance, and use meta-analytic Bayesian statistics to test the null hypothesis. The results favor the assumption that individual differences in WMC are, in fact, not (always) related to the magnitude of distraction. Implications for the nature of WMC are discussed.     

Attentional networks and visuospatial working memory capacity in social anxiety

Social anxiety is associated with attentional bias and working memory for emotional stimuli; however, the ways in which social anxiety affects cognitive functions involving non-emotional stimuli remains unclear. The present study focused on the role of attentional networks (i.e. alerting, orienting, and executive control networks) and visuospatial working memory capacity (WMC) for non-emotional stimuli in the context of social anxiety. One hundred and seventeen undergraduates completed questionnaires on social anxiety. They then performed an attentional network test and a change detection task to measure visuospatial WMC. Orienting network and visuospatial WMC were positively correlated with social anxiety. A multiple regression analysis showed significant positive associations of alerting, orienting, and visuospatial WMC with social anxiety. Alerting, orienting networks, and high visuospatial WMC for non-emotional stimuli may predict degree of social anxiety.     

Social neuroscience: understanding the pieces fosters understanding the whole and vice versa

Social science and neuroscience perspectives represent two ends of a continuum of levels of organization studied in psychology. Human behavior as a whole unfolds at social levels of organization, whereas much of the research in psychology has focused on cognitive and biological pieces of this whole. Recent evidence underscores the complementary nature of social, cognitive, and biological levels of analysis and how research integrating these levels can foster more comprehensive theories of the mechanisms underlying complex behavior and the mind. This research underscores the unity of psychology and the importance of retaining multilevel integrative research that spans molar and molecular levels of analysis.
