中文摘要：

自我–他人重叠（self-other overlap）是指交往关系中的个体不同程度地接受和理解他人的观念、资源,从而出现自我和他人信息表征的重叠现象。本研究通过两个实验考察自我–他人重叠对助人行为的影响以及观点采择的作用。实验1采用情境启动法,探讨高、低自我–他人重叠对助人行为的影响,结果发现重叠程度差异显著,重叠程度越高,助人行为越明显。实验2采用语义启动和情境启动法,考察观点采择在自我–他人重叠影响助人行为中的调节作用,结果发现观点采择和重叠程度的主效应显著,观点采择与重叠程度的交互效应显著,与控制组相比,观点采择条件下,助人行为显著增加。这些结果表明自我–他人重叠程度越高,助人行为越明显,而且观点采择起到了重要的调节作用。

英文摘要：

The relationship between perspective taking and helping behavior has always been the focus research within the fields of development psychology and social psychology. The previous research shows that perspective taking not only positively correlates to helping behaviors but also deepen the self-other overlap. Besides, effects of self-other overlap is short of being considered during the similar researches. Therefore, this thesis, through two experiments, studies self-other overlap and perspective taking as well as their effects on helping behavior.Experiment 1, a single-factor two-level within groups design, studies the different influences of high and low self-other overlap on helping behavior. Seventy university students（including 48 male, 22 female; mean age = 18.83） participated in the experiment and they were given a reward. Results show that the higher level of self-other overlap leads to the more obvious helping behavior, it means that the more we are intimate and similar, the more we are willing to help others. Experiment 2, a two-factor mixed design, studies what and how perspective taking and self-other overlap influence helping behavior. Sixty eight university students（including 27 male, 41 female; mean age = 18.97） were divided into two groups, which group had thirty four participants, and everyone had normal or corrected-to-normal version. Results prove the main effect of perspective taking and self-other overlap level are significant, the interactive effect of perspective taking and self-other overlap level is significant. To sum up, these results prove that self-other overlap have a significant effect on helping behavior, and perspective taking moderates the effect of self-other overlap on helping behavior.
