ERPs in the outcome phase

For EEG data in the outcome phase, the FRN, a fronto-central wave of negativity emerging for lost compared to won trials, was analyzed. The amplitude for a time window from 270 ms to 300 ms at electrode Fz were subjected to an ANOVA, in which the between-subjects factor was Trait Empathy (High Empathy Group, Low Empathy Group) and the within-subjects factors were Feedback (Won, Lost) and Provocation (High Provocation, Low Provocation).
