Humans are experts at reading others’ actions. They effortlessly navigate a crowded street or reach for a handshake without grabbing an elbow. This suggests real-time, efficient processing of others’ movements and the ability to predict intended movements. Here using interactive tasks and real-time recording of the bodily movements of two participants we intend to understand how they are able to predict each other’s action goals. Through the analysis of motor movements in interactive situations we will explore when the cues to action goals become available and where in the body they are located.
