Study of the Dynamics of Verbal and Non-verbal Interaction in Healthy Subjects, Through the Recording of Body Movements and Non-invasive Neurophysiological Techniques

Based on study literature, the investigators can say that our study aims to give an explanation not only from a behavioral point of view but also with respect to what are the neuronal mechanisms underlying our ability to perceive and analyze our own and others' actions. This is essential to fully understand the complexity of our social behaviors. The knowledge of these mechanisms has a high value and relevant implications for many research fields both within and outside the neurosciences. The project aims to study the neurobehavioral correlates of verbal and non-verbal communication. Through the use of non-invasive behavioral and neurophysiological techniques, the study intends to highlight the neurobehavioral markers that allow to quantify the temporal evolution of communication dynamics in healthy subjects.

• the investigators intend to verify whether individual differences in the ability to discriminate the verbal and non-verbal signals of others are reflected in significant differences in the way the same actions are performed.
• the investigators intend to quantify the behavioral variables during the execution of the action and observe how these are modified in the passage from a single execution to an interaction context.
• the investigators intend to study how the interactive context influences the cerebral and cortico-muscular oscillatory dynamics during the preparation of the action.
• the investigators intend to verify whether the activity of the motor system contributes not only to the execution of the action but also, if and, if so, to the perception of the actions of others
