“…First, several of the scales on the BRIEF, the most widely used behavioral rating measure of EF in developmental samples, have no parallel cognitive tasks, making empirical relationships between these two measurement approaches less likely (Toplak et al, ). Confirmatory factor analysis (CFA) has indicated that behavioral rating data obtained from the BRIEF coalesces around three higher‐order factors, metacognition, emotional regulation, and behavioral regulation, rather than reflecting the eight clinical scales or the metacognition index and behavioral regulation index (Egeland & Fallmyr, ; Fournet et al, ; Gioia, Isquith, Retzlaff, & Espy, ; Little et al, ). Similarly, EC was originally believed to consist of three distinct, but interrelated, abilities as measured by separate subscales: (a) Attentional Control ‐ the ability to voluntarily focus and shift attention, as well as disengage from alternative sources of attention using cognitive distraction; (b) Inhibitory Control ‐ the ability to inhibit contextually inappropriate behavioral responses; and (c) Activation Control ‐ the capacity to undertake an action when there is a strong tendency to avoid it (Eisenberg, Smith, Sadovsky, & Spinrad, ; Putnam et al, ).…”
