Models for the DCM were used to explore the hypothesized link between neural and behavioral task effects. Fourteen models: A 8 bilinear family models (exclusively linear, additive modulations with or without AI self-connection modulation), B 5 nonlinear family models (linear, additive modulations from VC and nonlinear, gated modulations from ACC and SPC, with or without AI self-connection modulation), and 1 null model (not shown) were included in the DCM model space as parsimonious hypotheses of modulations that explained the group-by-condition effect. The results of the BMS indicated that the optimal model for EP group was model 12 (see online Supplementary Fig. S1B) and the optimal model for the control group was model 13 (see online supplementary Fig. S1A).
