社会认知从根本上来说是人际的：个人的行为和性格严重影响其互动伙伴的信息处理。然而，认知神经科学的研究，部分是因为方法的限制，仍然主要是“感知中心”：专注于能力，动机和目标的社会感知，而在很大程度上忽略了人际关系的影响。在这里，我们通过检查感知情感表达和非表达的社会“目标”的神经基础来解决这个知识差距。16名感知者在观看目标讨论情感自传事件时，使用功能磁共振成像进行扫描。感知者不断地评估每个目标的情绪状态或眼睛注视的方向。目标的情绪表达对感知者大脑活动的影响取决于任务设置：当感知者明确关注目标的情绪时，表达预测了与心理状态推断相关的神经结构的活动，包括内侧前额叶和后扣带皮层。当感知者注意到目标的目光时，目标的表现力预测了与监测感觉运动状态和生物运动相关的区域的活动，包括躯体感觉皮层、梭状回和运动皮层。这些发现表明，表达目标影响信息处理的方式取决于知觉者的目标。更广泛地说，这些数据为理解人际社会认知的神经基础迈出了早期的一步。
Social cognition is fundamentally interpersonal: individuals' behavior and dispositions critically affect their interaction partners' information processing. However, cognitive neuroscience studies, partially because of methodological constraints, have remained largely “perceiver-centric”: focusing on the abilities, motivations, and goals of social perceivers while largely ignoring interpersonal effects. Here, we address this knowledge gap by examining the neural bases of perceiving emotionally expressive and inexpressive social “targets.” Sixteen perceivers were scanned using fMRI while they watched targets discussing emotional autobiographical events. Perceivers continuously rated each target's emotional state or eye-gaze direction. The effects of targets' emotional expressivity on perceiver's brain activity depended on task set: when perceivers explicitly attended to targets' emotions, expressivity predicted activity in neural structures—including medial prefrontal and posterior cingulate cortex—associated with drawing inferences about mental states. When perceivers instead attended to targets' eye-gaze, target expressivity predicted activity in regions—including somatosensory cortex, fusiform gyrus, and motor cortex—associated with monitoring sensorimotor states and biological motion. These findings suggest that expressive targets affect information processing in manner that depends on perceivers' goals. More broadly, these data provide an early step toward understanding the neural bases of interpersonal social cognition.
