Learning from social rewards predicts individual differences in self-reported social ability.

Area of Science:

• Cognitive Neuroscience
• Social Psychology
• Behavioral Economics

Background:

• Social skill involves adapting face-to-face behavior to changing interaction dynamics.
• Individual differences in social aptitude may stem from how effectively people learn from social rewards and punishments.

Purpose of the Study:

• To investigate the relationship between social aptitude and the ability to learn from different social reinforcers (genuine vs. polite smiles).
• To explore how learning from social rewards influences the adaptation of behavior in social interactions.

Main Methods:

• Participants engaged in experiments with hidden social contingencies involving genuine smiles, polite smiles, or nonsocial feedback.
• Behavioral learning and task contingency detection were assessed under different reinforcement conditions.

Main Results:

• Individuals demonstrated superior learning from genuine smiles compared to nonsocial feedback.
• Performance was hindered when switching actions following genuine smiles, indicating differential reinforcement value.
• The ability to detect contingencies and learn from social rewards correlated with self-reported social ability.

Conclusions:

• Individual differences in reinforcement learning, particularly motivation for social rewards, are linked to face-to-face social ability.
• Compromised reward learning may underlie social deficits observed in autism, depression, and schizophrenia.
