Abstract

Abstract: Previous neuroimaging studies demonstrated that ventromedial prefrontal cortex (vmPFC) activity reflects how much an individual positively views each person (impression). Here, we investigated whether the degree to which individuals think others positively view them (reflected impression) is similarly tracked by activity in the vmPFC by using fMRI and speed‐dating events. We also examined whether activity of the vmPFC in response to the faces of others would predict the impression formed through direct interactions with them. The task consisted of three sessions: pre‐speed‐dating fMRI, speed‐dating events, and post‐speed‐dating fMRI (not reported here). During the pre‐speed‐dating fMRI, each participant passively viewed the faces of others whom they would meet in the subsequent speed‐dating events. After the fMRI, they rated the impression and reflected impression of each face. During the speed‐dating events, the participants had 3‐min conversations with partners whose faces were presented during the fMRI task, and they were asked to choose the partners whom they preferred at the end of the events. The results revealed that the value of both the impression and reflected impression were automatically represented in the vmPFC. However, the impression fully mediated the link between the reflected impression and vmPFC activity. These results highlight a close link between reflected appraisal and impression formation and provide important insights into neural and psychological models of how the reflected impression is formed in the human brain.
