Chunk #34 — Results — Effects of Externalizing Proneness on Brain Responses to Performance Feedback — Externalizing proneness and brain response: Comparison of effects for TD versus TF measures
contributed at all uniquely to the prediction of externalizing proneness beyond TF delta, or if instead their associations with ESI-100 scores were attributable to TF delta. In the first step of the model, TF delta evidenced a significant association with Externalizing scores, F(1,147) = 9.07, p < .003. Neither the TD FRN nor the TD P300 yielded any significant increment in R2 when entered in steps 2 and 3, indicating that these components did not contribute uniquely to prediction beyond TF-delta. The results of this analysis confirm that the TF delta component captures all of the variance in the time-domain measures associated with externalizing proneness, and accounts for the apparent augmentation of TD FRN as well as the observed reduction in TD P300 response.
