Tasks that are known to measure inhibition of distractors (Eriksen flanker and shape-matching tasks), inhibition of action (go-no go and Stroop tasks), and dual-tasking, were administered to 146 participants. Confirmatory factor analysis (CFA) of performance data supported a model of independence of inhibition of distractors, inhibition of action, and dual-tasking rather than a model showing correlations among them. The Eriksen flanker task loaded significantly on inhibition of distractors; the go-no go and Stroop tasks loaded significantly on inhibition of action, and the dot memory and block-tapping tasks loaded significantly on dual-tasking. These findings provide support for the fractionation of the central executive and the Supervisory Attentional System (SAS), both of which are considered to be responsible for executive functions and attentional control.
