Analysis of performance accuracy revealed significant main effects of diagnosis [F (1,46) = 8220.41, p < .001] and trial type [F (3,44) = 19.30, p < .001], as well as a diagnosis × trial type interaction [F (3,44) = 2.41, p > .01; Figure 2]. Bonferroni-adjusted post hoc testing revealed that patients were significantly less accurate for BX trials [t (28.44) = 3.60, p = .004, corrected] but not for other conditions (p > .10), suggesting a specific deficit for trials requiring cognitive control. For averaged reaction time (RT), we found significant effects of diagnosis [F (1,46) = 612.55, p < .001] and trial type [F (3,44) = 108.75, p < .001]. The diagnosis × trial type interaction trended towards significance [F (1,44) = 2.75, p = .054; Figure 2].
