SOFEE: Impact of Another Person's Presence on Brain and Behavioral Performance
Study Details
Study Description
Brief 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.

Detailed Description
The main objective is to study the effect of the presence of others on cognitive performance and its evolution during development by behavioral and neural measures. The secondary objective is to identify factors (psychological characteristics such as personality traits) explaining individual, behavioral and neural differences, sensitivity to the presence of others.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Behavioral test and fMRI Neuropsychological tests and training in behavioral tasks and a Functional Magnetic Resonance Imaging (fMRI) exam |
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").

Outcome Measures
Primary Outcome Measures
- Behavioral performance evaluation [an average of 5 years]

Comparison of activity in the three populations tested (children, adolescents, adults)
Secondary Outcome Measures
- Determination of individual characteristics [an average of 5 years]
answers of self-assessment questionnaires and semi-directive interview
