Role of the first and second person perspective for control of behaviour: Understanding other people’s facial expressions

Abstract

Humans typically make probabilistic inferences about another person’s affective state based on her/his bodily movements such as emotional facial expressions, emblematic gestures and whole body movements. Furthermore, humans deduce tentative predictions about the other person’s intentions. Thus, the first person perspective of a subject is supplemented by the second person perspective involving theory of mind and empathy. Neuroimaging investigations have shown that the medial and lateral frontal cortex are critical nodes in the circuits underlying theory of mind, empathy, as well as intention of action. It is suggested that personal perspective taking in social interactions is paradigmatic for the capability of humans to generate probabilistic accounts of the outside world that underlie a person’s control of behaviour.
