虽然神经成像技术已被证明在评估神经反应方面很强大，但人们对基于扫描仪的神经活动是否与现实世界的心理体验有关知之甚少。一项联合功能性磁共振成像（fMRI）/经验采样研究调查了对基于扫描仪的社交拒绝的神经认知反应的个体差异是否与以下因素有关：（a）在现实社会交往中时时感到被社会排斥（“暂时的社会痛苦”）和（B）这些暂时的感觉与一天结束时对社会脱节的整体评估相对应的程度（“末日社会脱节”）。在基于扫描仪的社交拒绝过程中，与情感和疼痛处理相关的区域（背侧前扣带皮层、杏仁核、导水管周围灰质）表现出更大活动的个体报告说，他们在日常社交互动中感受到更大的瞬间社交痛苦。相比之下，在与记忆和自我参照记忆编码相关的区域（海马体，内侧前额叶皮层）中表现出更大活动的个体在瞬间社交困扰和一天结束时社交脱节之间表现出更强的对应关系，因此更大的瞬间社交困扰与更大的一天结束时社交脱节有关。这些研究结果补充了先前的工作，表明情感的瞬时和回顾性报告之间的分离，并表明这些过程依赖于可分离的神经系统。
Although neuroimaging techniques have proven powerful in assessing neural responses, little is known about whether scanner-based neural activity relates to real-world psychological experience. A joint functional magnetic resonance imaging (fMRI)/experience-sampling study investigated whether individual differences in neurocognitive reactivity to scanner-based social rejection related to: (a) moment-to-moment feelings of social rejection during real-world social interactions ("momentary social distress") and (b) the extent to which these momentary feelings corresponded with end-of-day global assessments of social disconnection ("end-of-day social disconnection"). Individuals who showed greater activity in regions associated with affective and pain processing (dorsal anterior cingulate cortex, amygdala, periaqueductal gray) during scanner-based social rejection reported feeling greater momentary social distress during their daily social interactions. In contrast, individuals who showed greater activity in regions associated with memory and self-referential memory encoding (hippocampus, medial prefrontal cortex) showed a stronger correspondence between momentary social distress and end-of-day social disconnection, such that greater momentary social distress was associated with greater end-of-day social disconnection. These findings complement previous work showing a dissociation between momentary and retrospective reports of affect and suggest that these processes rely on dissociable neural systems.
