In follow-up analyses there was a marginally significant effect for reward group on the drift rate in incongruent trials, t (403.85) = −1.66, p = .098, Cohen’s d = −0.16, 95% CI [−0.36–0.03].

Interestingly, allowing boundary shifts resulted in group differences in the differential boundary shifts for congruent versus incongruent trials, reaching marginal significance in the best fitting DMC with shifts (Mean difference score for boundary adjustments congruent group=11.42, SD = 29.35, Mean difference score incongruent group = 6.11, SD = 27.89; t (413) = 1.89, p = .06, Cohen’s d = 0.19, 95% CI [−0.01, 0.38], see Fig. 5 and Fig. 6 ), and significance in the standard DDM with shifts (Mean difference score congruent group=0.01, SD = 0.03, Mean difference score incongruent group=0.00, SD = 0.03; t (413) = 3.01, p = .003, Cohen’s d = 0.30, 95% CI [0.10, 0.49]).
