Summary

In a recent study, investigators provided the first neuroscientific data on social facilitation. This neuroimaging study, performed in the macaque monkey, shows a marked improvement in performance in a simple task when a congener is present compared to when the animal performs the task alone. This social facilitation is accompanied by a significant increase in brain activity within the fronto-parietal network of attention. No variation in activity, however, is observed in the cerebral network of motivation. These results argue in favor of the implication of attentional processes in the phenomenon of social facilitation. The challenge now is to determine whether social facilitation is always based on the attention network (whatever the task) or, alternatively, whether it increases activity in any cerebral circuit involved depending on the task performed and the population studied. This hypothesis, which the investigators have named the "multi-mediator model of social facilitation", has the advantage of reconciling the attentional and motivational theories of social facilitation, which are not mutually exclusive. This hypothesis also provides an explanation for the pervasiveness (across species and different ages for humans) of social facilitation. The main objective of SOFEE is to gather neuroscientific evidence to support the multi-facilitator model of social facilitation.

Conditions

  • Behavior and Behavior Mechanisms

Interventions

BEHAVIORAL

neuropsychological tests

Part 1: to determine the cognitive capacity, the subjects undergo different neuropsychological tests To determine individual characteristics children, adolescents and adults complete self-assessment questionnaires . Adults spend a semi-directive interview. Part 2: while the subject 1 (S1) is installed in the MRI, he perform behavioral tasks with the subject 2 (S2) (familiar peer of the same age ± 2 years) installed in an adjacent room, alternating periods when S1 is observed by S2 (condition "Social") and periods when S1 is not observed by S2 (condition "Alone").
