Clinical Trial Summary

Social psychology has long established that the mere presence of others influences the investigator's individual behavior and performance. "Social facilitation" refers to any improvement or deterioration of performance due to the presence of others. For more than a century, social psychology has acquired a solid knowledge of the principles governing this fundamental form of social influence.

But the underlying mechanism of social facilitation remains debated, as behavior alone cannot identify it with certainty. This major unresolved problem makes it particularly difficult to translate laboratory results on social facilitation into real applications in areas such as school or work, where others are ubiquitous. The purpose of this study will therefore be to identify the mediator of social facilitation.
