A fundamental characteristic of social exchanges is the synchronization individuals' behaviors, physiological responses, and neural activity.

Using functional near-infrared spectroscopy (fNIRS) hyperscanning, prefrontal were collected during interactions involving 84 participants (i.e., 42 dyads) aged 18-35 years.

Role playing is a central, but underappreciated, process in human evolution. It feature not only of the theatrical arts, everyday social interactions. While some role limited to enacting various personas self (e.g., wife, accountant, mother), others involve an impersonation people. The most basic form proto-acting, which refers transient engagement character portrayal, such as when we quote friend during conversation. During "act as" other person. However, there are means acting similar manner another person do impersonate them, merely emulate their behavior. This might happen learn motor skill from teacher or conform consumer choices masses. follower-based "acting like" critically important mechanism cultural evolution since it leads conformity and homogenization group I argue that evolutionary transition (emulation) (impersonation) occurred via emergence pantomime its narrative depiction actions was probably first step toward impersonating someone, leading initially proto-acting later performance cultures. Overall, study needs give greater consideration diverse manifestations life art.
