Summary of significant positive and negative correlations between NoGo error signaling and NEO-PI-R major domain scores obtained from the reduced model after excluding scales Agreeableness, Extraversion and Openness not showing any significant correlations in the full model.

Correlation coefficients were computed within an inclusive mask consisting of voxels with significant (p<0.025, family-wise corrected) error signaling during incongruent NoGo trials; x,/y/z: MNI-coordinates of the significant peak voxel in correlation analyses; Pv(FEW) indicates family-wise corrected significance of peak voxel; extent: number of significant (p<0.05, FWE) voxels; Pc(FWE): associated family-wise corrected p-value at the cluster-level; Partial R2: cluster averaged partial determination coefficient.
