Executive Summary
Behavioural synchronization between two individuals is a form of unintentional, automatic and unconscious interpersonal coordination. It concerns many social species. In humans, it has specific effects on many social functions including learning and prosociality. The purpose of this Master 2 internship is to explore the ontogeny of behavioural synchronization. More specifically, we will study the factors that can modulate behavioural synchronization in the pre-verbal child. This study is part of a larger project that will compare these results with measurements in dogs and explore the neural correlates of this synchronization.
The student will implement experimental protocols to measure and test the synchronization of the child’s walk from 2 to 3 years of age with that of an adult, in different contexts (familiarity with the adult; normal or wheelchair movement; presence of a goal or not). The tests will be carried out at the participants’ homes. Synchronization will be measured using recordings by motion sensors and offline from video images.
