权力层级与团队绩效关系：权力与地位的一致与背离

本研究致力于探讨在权力与地位不一致的背景下, 权力层级与团队绩效研究的分歧。本研究提出权力层级与团队绩效的关系取决于团队的层级一致性——权力与地位的匹配度。具体地, 当层级一致(权力与地位匹配)时, 权力层级促进团队绩效; 当层级不一致(权力与地位不匹配)时, 权力层级抑制团队绩效。本研究结合问卷、实验和二手数据方法来验证假设, 研究1通过对46个大学生创业实践团队的两阶段问卷调查, 发现层级一致性对权力层级与团队绩效的关系具有调节作用。此后, 研究2通过一项涉及64个团队的实验来揭示因果关系, 发现权力争夺在权力层级和层级一致性的交互与团队绩效的关系中起中介作用。最后研究3通过203个观测值的互联网公司二手数据重复验证了层级一致性的调节作用, 并提升了本研究的生态效度。本研究为权力层级的研究做出了一定的贡献, 并为团队管理提供了启示。     

发展性阅读障碍的噪音抑制缺陷

发展性阅读障碍的缺陷本质一直是研究者们关注和争论的焦点。近些年, 有研究者提出了一种新的理论假设——噪音抑制缺陷假设, 并得到了许多研究证据的支持。这种缺陷在视觉和听觉通道中均存在, 说明阅读障碍具有多感觉/一般性噪音抑制缺陷。但也有研究者指出知觉噪音抑制本质上反映了注意的功能, 因而这种缺陷可能是由注意缺陷导致的。目前还缺乏直接证据支持汉语阅读障碍存在噪音抑制缺陷。最后本文对该领域未来的发展方向做出展望。     

多维范式下神经组织行为学的哲学基础、理论框架和研究方法

神经组织行为学是指通过探究组织现象背后的生物学运作机理, 从神经生理视角发展并重构组织行为学框架的新兴多领域交叉学科。多维范式下的神经组织行为学包括从还原论到涌现论的哲学基础, 基于社会情境认知理论、跨层次研究和逆向推理的理论框架, 以及神经成像法和ANS测量法并行的研究方法。未来研究应注意神经组织行为学可能给组织理论带来的变革, 以及研究方法的未来走向。     

Descartes's Real Argument

It is still commonly supposed that Descartes based his argument for the mind-body distinction on the law of the indiscernibility of identicals. I argue that this interpretation is very unlikely to be correct. I explain three contemporary versions of this interpretation and say why I reject it. Basically, use of this law for Descartes's conclusion would require reference to human bodies or else the supposition, for the purpose of the argument, of reference to human bodies. But at the time Descartes formulated his argument, he would not have allowed either. Instead, I amend a different interpretation which others have found, and briefly defend it against one famous objection.     

Regulating the interpersonal self: strategic self-regulation for coping with rejection sensitivity

People high in rejection sensitivity (RS) anxiously expect rejection and are at risk for interpersonal and personal distress. Two studies examined the role of self-regulation through strategic attention deployment in moderating the link between RS and maladaptive outcomes. Self-regulation was assessed by the delay of gratification (DG) paradigm in childhood. In Study 1, preschoolers from the Stanford University community who participated in the DG paradigm were assessed 20 years later. Study 2 assessed low-income, minority middle school children on comparable measures. DG ability buffered high-RS people from interpersonal difficulties (aggression, peer rejection) and diminished well-being (e.g., low self-worth, higher drug use). The protective effect of DG ability on high-RS children's self-worth is explained by reduced interpersonal problems. Attentional mechanisms underlying the interaction between RS and strategic self-regulation are discussed.     

He said,she said: a quasi-signal detection analysis of daily interactions between close relationship partners

In everyday life, close relationship partners enact behaviors through which they may influence each other. To understand how these exchanges affect partners, previous research has emphasized the enactors' reports, the receivers' perceptions, or the congruence of the two. We developed a strategy based on classic signal detection theory that combined elements from these three approaches in a naturalistic daily experience study. Members of 58 heterosexual dating couples reported daily on their own behaviors and their perceptions of their partners' behaviors. Results showed that an enactor's beliefs about his or her behavior and the perceiver's interpretation combined to affect daily mood and relationship satisfaction. However, different patterns of results emerged for positive and negative behaviors, such that the enactor's perspective accounted for independent effects of negative behaviors. Results show the value of simultaneously considering the perspective of both parties in social interaction.     

童年晚期至青少年早期攻击和同伴侵害的关系:交叉滞后研究

采用整群抽样法抽取2178名小学生为被试（平均年龄11.05±0.69岁,男生1132人）自5年级追踪至8年级,通过纵向交叉滞后模型对攻击与同伴侵害间的关系进行考察。结果发现,各年级关系攻击均可预测之后的关系侵害,7年级身体攻击预测8年级身体侵害,此外6年级关系侵害经历对7年级关系攻击具有预测作用。攻击与同伴侵害间的纵向联系不存在性别差异。这些结果表明,童年晚期至青少年早期攻击与同伴侵害之间总体上符合连续性社交过程模型,即攻击对随后的同伴侵害具有更明显预测作用,但在小学升初中的学校过渡阶段关系侵害预测随后的关系攻击,部分支持两者间存在双向关系。该结果提示需关注儿童青少年的攻击与同伴侵害经历,采取措施避免其陷入攻击与同伴侵害间的恶性循环之中。     

Split-brain syndrome and extended perceptual consciousness

In this paper I argue that split-brain syndrome is best understood within an extended mind framework and, therefore, that its very existence provides support for an externalist account of conscious perception. I begin by outlining the experimental aberration model of split-brain syndrome and explain both: why this model provides the best account of split-brain syndrome; and, why it is commonly rejected. Then, I summarise Susan Hurley’s argument that split-brain subjects could unify their conscious perceptual field by using external factors to stand-in for the missing corpus callosum. I next provide an argument that split-brain subjects do unify their perceptual fields via external factors. Finally, I explain why my account provides one with an experimental aberration model which avoids the problems typically levelled at such views, and highlight some empirical predictions made by the account. The nature of split-brain syndrome has long been considered mysterious by proponents of internalist accounts of consciousness. However, in this paper I argue that externalist theories can provide a straightforward explanation of the condition. I therefore conclude that the ability of externalist accounts to explain split-brain syndrome gives us strong reason to prefer them over internalist rivals.     

运动抗抑郁作用的神经营养假说

身体锻炼具有促进心理健康的作用, 特别是通过体育锻炼能够有效缓解抑郁样症状及临床抑郁。有关抑郁的神经营养假说认为, 抑制成年海马神经发生以及神经营养因子的表达是导致抑郁的关键因素; 增加成年海马神经发生以及神经营养因子的表达能够产生抗抑郁的作用。本文通过综述认为, 运动能够诱导成年海马神经发生以及神经营养因子表达的增加可能是运动抗抑郁作用的主要机制, 且类似于药物的抗抑郁治疗作用。
