Chunk #35 — Results — Effects of Externalizing Proneness on Brain Responses to Performance Feedback — Externalizing proneness and performance monitoring: Dissociating effects for feedback-ERN versus response-ERN
The findings for the FRN in the current study differ dramatically from those reported by Hall et al. (2007) for the response-ERN. Whereas participants high in externalizing proneness showed markedly reduced response-ERN following performance errors in the Hall et al. investigation, higher ESI-100 scores were associated with no discernable reduction in theta activity reflecting the FRN following loss feedback—despite the fact that the test sample for the current study was markedly larger (N = 149) and incorporated all but three participants from the Hall et al. study. To further address the dissociation in effects for the two studies, we decided it would be informative to directly compare results for the theta-FRN and response-ERN in the subset of participants in the current study (n = 89) who also participated in the Hall et al. study. Participants in this subsample consisted of: 35 high ESI-100 scorers (12 male), 27 intermediate scorers (13 male), and 27 low scorers (8 male).
