Note. A/D = completed tasks on the ascending and descending limb; D-only = completed tasks on the descending limb only; Antisaccade = accuracy (proportion correct) in identifying a digit presented in a non-cued location; Stroop RT = reaction time interference effect (incongruent trial RT minus asterisk trial RT); Stroop Inc. acc. = color-naming accuracy on incongruent Stroop trials; SSRT = stop signal reaction time.
