Abstrakt: We examined the impact of IQ discrepancy (IQD) within (1) and above (1+) one standard deviation on executive function in HFA using the BRIEF. We hypothesized that IQD would benefit executive function. IQD 1 is hallmarked by deficits in BRIEF indices and subscales inhibit, shift, initiate, working memory, planning and organization, and monitor (MANCOVA, p < .003, corrected). As IQD increases to 1+, deficits are fewer, corresponding to subscales inhibit, shift, and initiate. Pearson correlations (p < .004, corrected) identify significant relationships for FSIQ and BRIEF Global Composite (r = -.66, p = .002) and Metacognition subscales plan/organize (r = -.64, p = .003) and monitor (r = -.63, p = .004). Results suggest IQD 1+ favoring verbal IQ may support these aspects of executive function in HFA.
