近些年來,，認(rèn)知神經(jīng)科學(xué)家們發(fā)現(xiàn),，人們很少在隔離的情況下作出決定。人類對(duì)他人怎么想是敏感的,。給母親快速打一個(gè)電話或與朋友做一席長(zhǎng)談會(huì)讓我們?cè)谧鞒瞿骋粵Q定之前三思,，或會(huì)給予我們按計(jì)劃銳意向前的勇氣。Scott Huettel及其同事設(shè)計(jì)了一個(gè)實(shí)驗(yàn),，該實(shí)驗(yàn)中的參與者——他們是沒有撲克專長(zhǎng)的一般人——會(huì)玩一種以某個(gè)人或電腦為對(duì)手的簡(jiǎn)單的虛擬撲克游戲,。這些參與者在開始玩電腦游戲前會(huì)與其人類對(duì)手相見并握手。某些時(shí)候,，玩家拿到了一手輸牌且必須決定是否要詐唬他們的對(duì)手,。

A Distinct Role of the Temporal-Parietal Junction in Predicting Socially Guided Decisions
R. McKell Carter1,2,3, Daniel L. Bowling1,2, Crystal Reeck1,4, Scott A. Huettel1,3,4,*
To make adaptive decisions in a social context, humans must identify relevant agents in the environment, infer their underlying strategies and motivations, and predict their upcoming actions. We used functional magnetic resonance imaging, in conjunction with combinatorial multivariate pattern analysis, to predict human participants’ subsequent decisions in an incentive-compatible poker game. We found that signals from the temporal-parietal junction provided unique information about the nature of the upcoming decision, and that information was specific to decisions against agents who were both social and relevant for future behavior.
