Primary outcomePrimary: Cortisol AUCi — -93.6397; -68.0959; -106.9105 (ug/dL)*minutes

Summary

The purpose of this experiment is to determine the mechanisms through which parental buffering of stress physiology during affective stimulus presentation diminishes with pubertal development and whether this diminution of effectiveness extends to social buffering by peers (best friends), in comparison to a lack of social partners.
