摘　　要：本研究通过经典的金钱博弈任务,以FRN和P300为反应指标,探讨了自身获益或损失对朋友结果评价分别会产生何种影响,以及这种影响模式是如何受到个体自我建构方式调节的。结果发现,在自身获益条件下,观看朋友损益之间的FRN和P300差异不再存在;在自身损失条件下,虽然观看朋友输赢之间的P300差异消失了,但FRN差异依然显著。不仅如此,无论自身得失,独立型自我建构启动组在观看朋友损益上的FRN差异均不再显著,但在自身获益后看到朋友损失能激发更强的P300波幅。本研究结果表明:(1)对朋友的结果评价模式并非固定不变,而是会随个体自身所处得失境遇的不同而有所区别;(2)相对于互依型自我建构启动组,独立型自我建构启动组在面对朋友的得失时表现得更为冷漠并更具竞争性。Previous studies have indicated that the alternative evaluation responses to watching the gambling results of one’s friends can be affected by self-interest concerns.However,until now,no systematic discussion is available addressing whether one’s own different gains and losses will have different effects on the evaluation mode on a friends’gambling results;moreover,it remains unclear how this effect mode is modulated by the mode of an individual’s self-construction.Research in this domain is conducive to identifying the dynamic changes of self-other sharing representations in the context of complex interpersonal interactions.Furthermore,this research provides empirical evidence toward understanding people’s mentality of social interaction in the context of different cultures.This study presents a step by step discussion of the above problems via classic monetary gambling tasks in three separate experiments using the FRN and P300 as electrophysiological response indexes.This pilot study mainly investigated the evaluation model for a friends’gambling results without involving one’s own gains and losses.This aimed to verify previous research results and provided a baseline level for investigating the responses to the evaluation of a friends’gambling results.A total of 17 subjects and their same-sex friends participated in this pilot study.When an individual only observed but did not participate in gambling in person,such observing of a friends’gambling results can generate an electrophysiological response mode similar to own gains and losses.Many researchers suggested that such"mirror image"processing represented evidence for sharing presentations between an individual and his friends,i.e.,the part that involves friends in people’s self-concept.Experiment 1 explored the neural electrophysiological responses that occur in the two parties when one observes the gains and losses of a friend after he himself has had the experience of losing and winning money in gambling.A total of 38 subjects and thei
