因果力比较范式下对效力PC理论的检验

在用图形方式集中呈现信息的条件下,用因果力大小比较的实验范式检验效力PC理论。233名大学生被试对不同化学药物影响动物基因变异的能力做大小比较判断。结果发现,对单一因果关系因果力大小的比较判断具有以下3个特点：（1）不对称性：在预防原因条件下的因果力判断一般符合效力PC理论,而在产生原因条件下的因果力判断一般不符合效力PC理论;（2）在同时变化协变值DP和结果基率P(E|~C)的产生原因条件下,多数被试使用DP规则。这与概率对比模型的预测相一致,而不支持效力PC理论;（3）在固定协变值DP而只变化结果基率P(E|~C)的产生原因条件下,多数被试使用变异比RP规则。这是目前所有的因果推理理论都不能解释的现象。     

The empowering effect of punishment on forgiveness

We examined the process by which punishment enables forgiveness, testing the proposition that punishment restores a sense of justice to victims, an experience that is empowering. In Study 1 (N = 69), university students received insulting feedback and were given the opportunity (or not) to sanction the offender. In Study 2 (N = 91), participants imagined having the opportunity (or not) to recommend punishment for a person who had vandalized their house. A two‐step mediation model (punishment justice restoration empowerment forgiveness) was supported in these two studies. In Study 3 (N = 227), punishment options were expanded to test the role of victim voice in the context of third‐party and personal retributive and restorative justice responses to workplace bullying, as well as taking into account revenge as an alternative to justice restoration. When victims had voice, empowerment again played a central indirect role in relations between punishment and forgiveness.     

Experimental Philosophy of Explanation Rising: The Case for a Plurality of Concepts of Explanation

This paper brings together results from the philosophy and the psychology of explanation to argue that there are multiple concepts of explanation in human psychology. Specifically, it is shown that pluralism about explanation coheres with the multiplicity of models of explanation available in the philosophy of science, and it is supported by evidence from the psychology of explanatory judgment. Focusing on the case of a norm of explanatory power, the paper concludes by responding to the worry that if there is a plurality of concepts of explanation, one will not be able to normatively evaluate what counts as good explanation.     

刺激前alpha振荡对视知觉的影响

人类对感觉阈限附近的视觉刺激的知觉不总是一致的。为探究这种视知觉不一致的现象及其神经机制, 一些研究者关注刺激前脑内自发alpha神经振荡(8~13 Hz)对视知觉的影响。近年来的研究发现, 刺激前alpha振荡能量的降低能提高被试的探测击中率, 但不能提高知觉精确度; 而刺激前alpha振荡的相位能预测被试能否成功探测刺激。刺激前alpha能量被认为调控了视皮层的基础活动强度; alpha能量的降低反映了皮层基础活动的增强, 进而提高了对较弱刺激的探测率。刺激前alpha相位则被认为调控了皮层兴奋和抑制的时间; 大脑在刺激呈现时的不同状态(兴奋/抑制)决定了最终的知觉结果。     

领导人际情绪管理和员工建言的关系：有调节的中介效应分析

近年来,领导人际情绪管理（LIEM）作为一种管理和调节下属消极情绪的领导行为正逐渐受到学界关注。本研究通过问卷调查,搜集了314份员工和领导的配对数据。研究结果显示：领导人际情绪管理积极影响员工建言行为;下属信任在领导人际情绪管理和员工建言行为间起到部分中介作用;权力距离对下属信任的中介效应起到调节作用。     

权力和地位对信任行为的影响

采用两个实验探讨了权力和地位对信任和不信任行为的影响。实验1首先通过角色分配法操纵被试的权力感(高vs.低),然后采用信任和非信任博弈任务来测量被试的信任和不信任行为。结果发现,在信任行为上,高权力者比低权力者存在更低的信任水平;但在不信任行为上,二者不存在显著差异。实验2同时操纵被试的权力和地位水平,探索二者对信任和不信任行为的影响。结果发现:在信任行为上,高权力者比低权力者存在更低的信任水平,与之相反,高地位者比低地位者存在更高的信任水平,并且权力和地位的交互作用不显著;而在不信任行为上,权力和地位的效应均不显著。该研究结果说明,(1)权力负向影响信任行为,而地位正向影响信任行为;(2)权力和地位对信任的影响是独立的。     

The generalized sense of power is a psychological resource: Evidence from a disaster response field training exercise

We examined whether the generalized sense of power—the belief that one is able to influence others in one's various social relationships—serves as a psychological resource that enables leadership in high-stakes, unfamiliar group challenges, such as emergencies or crises. We studied current and prospective humanitarian aid professionals (N = 180) during a major field training exercise: a three-day, immersive simulated humanitarian crisis. Individuals who entered the simulated crisis with a greater sense of power in their social relationships experienced lower stress (anxiety), behaved more assertively, and left the simulation with a relatively heightened desire to lead, despite not being deemed better leaders by their teammates. Lacking an initial sense of power was associated with experiences (e.g., feeling timid) that undermined the desire to lead. These results suggest that the psychological sense of power is a key leadership resource, without which one may be at risk of self-selecting out of leadership.     

Between Recognition and Mis/Nonrecognition: Strategies of Negotiating and Performing Identities Among White Muslims in the United Kingdom

This article explores white British Muslim experiences of, and strategic performative responses to, the (mis/non)recognition of their seemingly incompatible religious and ethnic identities. Based on in-depth interviews (N = 26), it highlights how the different identity categories they hold relate to one another, influencing processes of perceived recognition in interactional contexts. White British Muslims perceive their ethnic and religious identities to be (mis/not) recognized in complex and contradictory ways. Their identities are affirmed, denied, erased, and/or incorrectly ascribed, sometimes simultaneously, by relevant others in different contexts. Performative strategies such as the adoption, maintenance, or removal of identity markers are used consciously and agentically in attempts to take back control over how their identities are (mis/not) recognized. At times deliberate performative acts leading to misrecognition are orchestrated by white Muslims themselves to not only minimize the risk of experiencing possible harm or marginalization but also to transgress and challenge norms. They also assert their multiple identities as a response to (mis/non)recognition and claims of their identities being incompatible, regardless of the repercussions that may result in them being placed at the margins of, or excluded from, their ingroups.
