Competition influences outcome processing involving social comparison: An ERP study.

Area of Science:

• Neuroscience
• Social Psychology
• Cognitive Science

Background:

• Outcome evaluation in complex social contexts involves self-assessment and social comparison.
• Previous event-related potential (ERP) studies focused on non-competitive social comparison.
• The neural processing of social comparison in competitive environments remains underexplored.

Purpose of the Study:

• To investigate how the brain processes social comparison outcomes during competition.
• To compare neural responses to social comparison in competitive versus non-competitive scenarios.
• To examine the influence of self-related outcomes on social comparison processing.

Main Methods:

• Participants performed an attentional task alongside peers.
• Self-related and social comparison outcomes were presented.
• Rewards/punishments were contingent on social comparison (competition) or self-related outcomes (non-competition).
• Event-related potentials (ERPs), specifically P300 and late positive potential (LPP), were recorded.

Main Results:

• In competition, positive social comparison outcomes elicited a larger P300 than negative outcomes; this was absent in non-competition.
• A larger LPP response to negative social comparison outcomes occurred when participants received a positive self-related outcome during competition.
• Competition appears to intensify late-stage outcome processing involving social comparison, potentially leveraging self-related information.

Conclusions:

• Competition modulates the neural processing of social comparison outcomes.
• The brain's response to social comparison is influenced by the presence of conflict and the nature of self-related outcomes.
• Findings suggest competition strengthens late neural processing of social comparison, integrating self-related performance information.
