Psychological and Biological Validation of a Novel Digital Social Peer Evaluation Experiment (digi-SPEE)

Negative social evaluation is associated with psychopathology. Given the frequency of evaluation through increasingly prevalent virtual social networks, increased understanding of the effects of this social evaluation is urgently required. A new digital social peer evaluation experiment (digi-SPEE) was developed to mimic everyday online social interactions between peers.
