In this study, FRN and P300 were used as response indicators to explore the effects of self-gains or losses on friends’ outcomes and how this mode of influence was regulated by the individual’s self-construction. The results showed that the FRN and P300 differences between watching friends’ gains and losses no longer existed under the condition of self-gains, and the FRN differences were significant even though the P300 differences between watching friends’ losses and gains disappeared under the condition of self-losses. Furthermore, no significant FRN differences were observed in the self-constructed group regardless of self-gains or losses. However, watching friends’ losses after self-gains elicited stronger P300 amplitude. The results of this study showed that: (1) the result evaluation model of friends was not fixed but varied with the individual’s own situation of gains and losses; (2) compared to the interdependent self-construction priming group, the independent self-construction priming group was more indifferent and more competitive in the face of friends’ gains and losses.

Key words: self-other representation, monetary gambling task, self-construal, FRN, P300
