The present study aimed to investigate the impact of social comparison on risk-taking behaviors and neural underpinnings within a competitive context. Participants who thought they were playing against stranger in gambling task actually programmed computer. Eighty-eight college students assigned one three conditions (downward, upward, parallel) by varying probability gain. Behavioral results showed that disadvantage led increased risk-taking. Event-related potential data analyses showed, parallel condition, significantly larger Feedback-Related Negativity (FRN) was induced self's safe decision than risky loss rather However, upward downward conditions, FRN emerged solely response decisions. On P3 component, participants condition no significant difference their gain or loss, while other two did. highest amplitude, delta/theta power, aperiodic activity found closely matched condition. Finally, stronger power correlated with less decision. Overall, findings indicate parity heightens emotional arousal engages more cognitive resources.
