人际好奇心(IPC)是社会交往中一种重要的内在动机，但对其神经机制的研究较少。在三智能体(自我、他人或计算机)互动赌博任务中，我们记录了事件相关电位(ERPs)，以指示参与者是否会被告知他们自己、另一个参与者或计算机的结果，从而满足好奇心(CWS)或不满足好奇心(CWN)。结果表明，与CWS线索刺激相比，CWN线索在自身和其他条件下都能在线索开始后约400ms至700ms之间诱发出较大的晚期正向成分(LPC)，但在计算机条件下不存在。此外，参与者对他人的结果比对电脑的结果有更强的好奇心。最重要的是，参与者对好奇心的主观评分与CWN线索引发的LPC的幅度显著相关。此外，当参与者得知他们不会被告知对方的结果时，IPC量表中“对情绪的好奇心”子量表的分数与LPC幅度显著相关。我们认为：(1)人际信息对个体具有重要意义，IPC是一种重要的社会动机；(2)LPC幅度对IPC敏感。(C)2013爱思唯尔B.V.保留所有权利。
Interpersonal curiosity (IPC) is an important intrinsic motivation in social interaction, yet studies focused on its neural mechanism are rare. In a three-agent (Self, Other, or Computer) interactive gambling task, we recorded event-related potentials (ERPs) to a cue stimuli indicating whether participants will be informed of their own, of another participant's or the computer's outcomes such that curiosity will be satisfied (CWS) or curiosity will not be satisfied (CWN). The results showed that relative to the CWS cue stimuli the CWN cue evoked a larger late positive component (LPC) between approximately 400 ms and 700 ms after cue onset in both the Self and Other conditions, but not in the Computer condition. Additionally, participants reported stronger curiosity in the Other's outcomes than in the Computer's outcomes. Most importantly, participants' subjective rating of curiosity was significantly correlated with the amplitude of the LPC elicited by the CWN cue. Furthermore, scores in the "curiosity about emotion" subscale of the IPC Scale was significantly correlated with the LPC amplitude when the participants learn they will not be informed of the Other's outcomes. We suggest that (1) interpersonal information is of great significance to individuals and IPC is an important social motivator, and (2) LPC amplitude is sensitive to IPC. (C) 2013 Elsevier B.V.
