风险对两类跨期选择的影响：一项ERP研究

该研究利用ERP技术,采用伴随风险的跨期选择任务比较了两类跨期选择（立即vs.延迟、延迟vs.延迟）,并探究了风险（零风险、低风险、高风险）对两者跨期选择影响的神经动力学机制。ERP结果显示,对于立即vs.延迟和延迟vs.延迟,在N2和N400上前者大于后者,在LPC上后者大于前者;风险对两者在时程上的影响趋于一致。因此,其加工可能是先对奖赏在风险维度上进行折扣,再与延迟时间进行整合形成奖赏预期,而后做出选择。     

语言线索下视觉空间知觉任务的性别差异

为了探索不同方位辨别方式的男女差异,采用自编的经过心理测量学检测符合指标的空间知觉量表和三个语言线索下方位辨别任务范式实验,在测验和实验3中设计两种空间知觉加工方式,即东西南北和前后左右;在实验1中设计东西南北;在实验2中设计前后左右。测验,实验1和实验3均发现,在东西南北方位辨别上存在显著的性别差异,且男生优于女生;测验,实验2和实验3均发现,在前后左右方位辨别上不存在显著的性别差异。这表明男生更擅长于使用东西南北的方位辨别方式。     

领导力的社会认同理论：主要内容及研究进展

作为“以下属为中心”的领导力理论,领导力的社会认同理论是社会心理学与领导力研究结合的代表.该理论采用社会认同解释领导力产生和发挥作用的过程,主要命题为：（1）群体成员通过社会认同选择有效的领导,具有高群体原型代表性的领导者最具有效性;（2）领导者可以通过塑造下属成员的社会认同来实施领导.除了以上内容外,还对该理论的实验证据及优缺点也进行了系统阐述,同时与其它领导力理论进行了整合,最后提出了未来研究的方向.     

Can you forgive? It depends on how happy you are

This paper examined how individual group status and happiness influence forgiveness. In Study 1, happiness was treated as a trait difference: highly happy people, compared with very unhappy people, were found to be more willing to forgive murderers. More important, an interaction effect between happiness and group status on forgiveness was found, that is, highly happy people tended to be more forgiving when either ingroup or outgroup members were killed; unhappy people, however, tended to be less forgiving about murder when ingroup rather than outgroup members were killed. In Study 2, happiness was treated as an emotional state difference: happiness, rather than sadness, was found to bring greater forgiveness. Moreover, consistent with the interaction effect displayed in Study 1, happy participants tended to forgive more when ingroup or outgroup members were hurt; sad participants tended to forgive less when ingroup members rather than outgroup members were hurt. Implications for connections between happiness, group membership, and forgiveness are discussed.     

Life Satisfaction Among Recent Immigrants in Canada: Comparisons to Source-Country and Host-Country Populations

Research examining how changes in life circumstances affect subjective well-being has been dominated by set-point theory. New evidence challenges the assumptions of this theory, indicating that major life events can result in lasting changes to individuals’ life satisfaction. This study examines whether changes in national-level conditions following migration affect the life satisfaction of immigrant groups from different source countries by comparing the average life satisfaction levels of immigrant groups to that of non-emigrants in their source countries. Life satisfaction differences between immigrant groups and the native-born population in Canada are also examined. Results show that migration to a country with improved national-level conditions increases immigrants’ life satisfaction. Most immigrant groups had higher life satisfaction than their source-country counterparts and life satisfaction scores were similar to those of the native-born population. These findings persist when the sample includes immigrants who have resided in Canada for up to 20 years.

Prospective emotion enables episodic prospection to shift time preference

The episodic effect suggests that episodic prospection (imagining future events) can effectively reduce time discounting, the propensity to discount the value of delayed rewards relative to immediate ones. However, less clear is how episodic prospection modulates time preference. As engagement in episodic prospection usually evokes prospective emotions, it was proposed that episodic prospection might work by inducing prospective emotions. Although one previous study has attempted to provide evidence to the emotional account of the episodic effect, shortcomings in its experimental design make its conclusion questionable. In this study, we replicated previous experimental design with improvements to further test the effects of prospective emotion on time preference. By manipulating the emotional valency associated with episodic prospection in a delay discounting task, we found that positive episodic prospection attenuated time discounting; negative episodic prospection exacerbated time discounting; and episodic prospection did not shift time preference when prospective emotion is removed. These results were essentially identical to the result of the previous study. Together, these studies suggested that the effects of episodic prospection depended on prospective emotion. Thus, one cannot ignore prospective emotion if counting on episodic prospection to combat humans’ impulsive behaviours.     

聋生1秒以下与以上的视时距知觉研究

采用时距二分任务,探讨聋生在视觉通道的1s以下和1s以上时距知觉的特点。结果发现,在1s以下条件下,聋生时距判断准确性低于普通学生;聋生CNV峰值与LPCt波幅低于普通学生,CNV潜伏期短于普通学生,LPCt峰值潜伏期长于普通学生。在1s以上条件下,聋生时距判断准确性高于普通学生;聋生N1、P2、CNV与LPCt成分各项指标与普通学生均没有显著差异。这说明,听觉丧失损伤了聋生1s以下的时距记忆与决策过程,支持了普遍缺陷假设;但听觉丧失未对聋生1s以上时距加工产生显著影响,支持了感觉补偿机制。因此,时距长度在听觉丧失对视觉时距知觉的影响中具有调节作用,为时间认知的分段综合模型提供了新的支持证据。
