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 less than 0.003, corrected). As IQD increases to 1+, deficits are fewer, corresponding to subscales inhibit, shift, and initiate. Pearson correlations (p less than 0.004, corrected) identify significant relationships for FSIQ and BRIEF Global Composite (r = -0.66, p = 0.002) and Metacognition subscales plan/organize (r = -0.64, p = 0.003) and monitor (r = -0.63, p = 0.004). Results suggest IQD 1+ favoring verbal IQ may support these aspects of executive function in HFA.
