发展心理学的数据表明，社会情感能力的增长与婴儿对社会刺激的敏感性之间存在联系。本研究的目的是在健康成人中寻找这种关系的证据。35名参与者被招募，根据他们的得分高于85或低于15个百分点的共情商问卷（EQ， Baron-Cohen和Wheelwright， 2004）。功能磁共振成像（fMRI）用于比较社会和非社会（金钱）奖励线索的神经反应。与高情商组相比，低情商组的大脑奖励系统，特别是右侧伏隔核，在对预测社会奖励的线索（视频显示赞许的手势）做出反应时，表现出较低的活动，但在对金钱奖励做出反应时，该区域的活动增加。我们的数据为自我报告的社会熟练程度缺陷和对积极社会刺激的动机显著性敏感性降低之间的联系提供了证据。
Data from developmental psychology suggests a link between the growth of socio-emotional competences and the infant's sensitivity to the salience of social stimuli. The aim of the present study was to find evidence for this relationship in healthy adults. Thirty-five participants were recruited based on their score above the 85th or below the 15th percentile of the empathy quotient questionnaire (EQ, Baron-Cohen and Wheelwright, 2004). Functional magnetic resonance imaging (fMRI) was used to compare neural responses to cues of social and non-social (monetary) reward. When compared to the high-EQ group, the low-EQ group showed reduced activity of the brain s reward system, specifically the right nucleus accumbens, in response to cues predictive of social reward (videos showing gestures of approval)-but increased activation in this area for monetary incentives. Our data provide evidence for a link between self-reported deficits in social proficiency and reduced sensitivity to the motivational salience of positive social stimuli.
