Chunk #37 — Results — Effects of Externalizing Proneness on Brain Responses to Performance Feedback — Externalizing proneness and performance monitoring: Dissociating effects for feedback-ERN versus response-ERN
of individuals low and high in externalizing proneness were employed in the analysis in place of continuous scores for all participants, F[1,60] = 9.32, p < .003.) To further ensure comparability of measures across the two experiments, we repeated the GLM using TF-theta component scores corresponding to the ERN in place of TD ERN peak scores, in conjunction with TF-theta scores for loss trials from the current study; Hall et al. (2007) reported that the theta component captured most of the variance related to externalizing proneness in the response-ERN. This analysis likewise produced a significant FRN/ERN × Externalizing interaction, for both continuous ESI-100 scores (F[1,87] = 5.64, p < .02) and low versus high group comparisons (F[1,60] = 7.92, p <.007), with follow-up tests confirming a robust association with externalizing proneness for the ERN-theta component only.
