他人知识状态觉知对幼儿名词学习的影响

本研究采用两个实验考察了他人知识状态觉知对不同语言能力幼儿名词习得的影响。参加实验的被试是来自上海市三所幼儿园的89名3～4岁幼儿。实验一发现,高语言能力幼儿在确定和不确定两种实验条件下的名词习得有显著差异,确定条件下的得分高于不确定条件。一般语言能力幼儿未表现出上述区别;实验二进一步发现高语言能力幼儿能忽视表面的语气线索所表达的迟疑,影响他们词语学习的是对他人知识状态的深层觉知。     

不同社交媒体使用目的对员工工作绩效的影响机制

基于工作要求-资源理论, 本研究探讨了两种社交媒体使用目的对员工工作绩效影响的内部作用机制, 进而分析两种社交媒体使用目的对员工工作绩效的影响效果。通过369份“领导者-下属”匹配数据, 研究发现：(1)基于工作、社交的社交媒体使用均促进员工工作绩效; (2)基于工作、社交的社交媒体使用均通过工作投入影响工作绩效, 基于社交的社交媒体使用还通过关系冲突影响工作绩效; (3)社交媒体的工作使用和社交使用对员工工作绩效的影响存在相互替代关系。本研究结果不仅从理论上拓展了社交媒体使用的研究视角, 为后续研究提供新的理论框架, 同时通过比较分析为组织管理社交媒体使用提供了新思路。     

Local Solidarity

In this article I am particularly interested in the question of solidarity within the boundaries of one's own country. I discuss a qualified beneficence requirement, which claims that we ought to prevent something very bad from happening if it is in our power and if we can do it without sacrificing anything morally significant. I also discuss a fair-share principle, according to which, in Liam B. Murphy's version, "the sacrifice each agent is required to make is limited to the level of sacrifice that would be optimal if the situation were one of full compliance". I argue that the qualified beneficence requirement is reasonable only in the proximity of the one who needs help. When there is no proximity we ought to be guided by a fair-share principle. I also argue that there is an intimate relation between the fair-share principle and the welfare-state ideology.     

Predictions,precision, and agentive attention

Ransom, Fazelpour, and Mole (this journal - 2017) raise an important puzzle for the ‘prediction error minimization’ account of cognitive processing. That account depicts all cognitive processing as fundamentally in the business of minimizing prediction errors concerning the evolving flow of sensory information. One of the cornerstones of these highly ambitious, would-be unifying accounts is their depiction of attention as nothing other than the process of optimizing the precision (inverse variance) of critical prediction error signals. But that story, Ransom et al. suggest, cannot accommodate voluntary shifts of attention. In this paper, I show why this challenge to the grand unifying project fails. It fails because it locates the origins of voluntary attention in complexes of unanalyzed desire rather than in changing complexes of beliefs.     

Closeness or compassion? Relatedness and causal control influence helping via distinct pathways

ABSTRACT

Why do people feel compassion? Two largely separate research literatures – one driven by evolutionary psychology and one driven by attribution theory – have shown that feelings of compassion for needy individuals and subsequent helping are predicted by both genetic relatedness and causal control. Research also suggests that emotional closeness, rather than compassion, motivates help for family. In two studies, we tested the role of genetic relatedness and control on cognitive and emotional mediators of helping. Results revealed that relatedness and control had distinct and independent effects on willingness to help needy individuals that were mediated by emotional closeness and compassion, respectively. These results provide a unique bridging of disparate literatures and suggest that emotional closeness and compassion serve distinct functions in facilitating prosocial behavior.
