作为一个社会性物种，人类敏锐地意识到暗示包容性地位的线索。本研究描述了个体预期社会反馈时的行为和神经反应。在两项功能性磁共振成像研究中，参与者（N = 42）对假定的同龄人做出社会判断，然后从这些人那里得到反馈。特别有趣的是，当参与者等待社会反馈时，神经活动发生了变化。在这一预期期，在腹侧纹状体（VS）和背内侧前额叶皮层（dmPFC）中观察到了增加的神经活动，腹侧纹状体是大脑奖励回路的中心组成部分，背内侧前额叶皮层是一个与对他人的心理化有关的大脑区域。个体在拒绝敏感性高表现出更大的反应，在VS和dmPFC时，预期的积极反馈。这些发现提供了对参与预测社会评价的神经机制的初步了解，以及作为拒绝敏感性基础的认知过程。
As a social species, humans are acutely aware of cues that signal inclusionary status. The present study characterizes behavioral and neural responses when individuals anticipate social feedback. Across two functional magnetic resonance imaging studies, participants (N = 42) made social judgments about supposed peers and then received feedback from those individuals. Of particular interest was the neural activity occurring when participants were awaiting social feedback. During this anticipatory period, increased neural activity was observed in the ventral striatum (VS), a central component of the brain’s reward circuitry, and dorsomedial prefrontal cortex (dmPFC), a brain region implicated in mentalizing about others. Individuals high in rejection sensitivity exhibited greater responses in both the VS and dmPFC when anticipating positive feedback. These findings provide initial insight into the neural mechanisms involved in anticipating social evaluations, as well as the cognitive processes that underlie rejection sensitivity.
