This study aimed to investigate the influence of dispositional self-construal on self-related processing. Event-related potentials (ERPs) were recorded for a participant's own and a famous person's name in a three-stimulus oddball task. The results showed greater P2 and P3 amplitudes induced by one's own than by a famous person's name in both independent and interdependent self-construal groups. However, no N2 amplitude differences were found between the partcipant's own name and a famous person's name in either group. Moreover, the strength of the P2 effect (own vs. famous person's name) was stronger in the independent than in the interdependent self-construal group, whereas the P3 effect was similar between these two groups. Thus, these findings might reflect fast modulation of self-related processing by dispositional self-construal.
本研究旨在探讨特质性自我构念对自我相关加工的影响。在一个三刺激Oddball任务中，记录了参与者对自己名字和名人名字的事件相关电位（ERP）。结果显示，在独立型和互依型自我构念组中，自己名字诱发的P2和P3波幅均大于名人名字诱发的P2和P3波幅。然而，在两组中，参与者自己名字和名人名字之间均未发现N2波幅差异。此外，P2效应（自己名字与名人名字相比）的强度在独立型自我构念组中比在互依型自我构念组中更强，而两组之间的P3效应相似。因此，这些发现可能反映了特质性自我构念对自我相关加工的快速调节。
