Behavioural, Cognitive and Neural Mechanisms of Human Social Interaction

Social interaction is a fundamental part of what makes us human and draws on a wide range of neural and cognitive mechanisms. This review summarises current research in terms of four major brain networks. First, the social perception network responds selectively to viewing and interpreting other people’s faces and bodies. Second, the theory of mind network is engaged when people think about other people’s beliefs and knowledge states. Third, the mirror neuron network has a role in understanding and imitating actions. Fourth, the emotion network shows some selective responding to emotional facial expressions and when people empathise with other’s pain. The role of these four networks in dynamic social interactions and real-world communication is also considered.
