Note. Means (Standard Deviations) for participant’s Analysis of Covariance (ANCOVA) controlling for pre-morbid IQ (WAIS-III Vocabulary Subtest). CFM=Color Figure Mazes. Partial Eta-Squared was used for effect size. ^*Statistically significant at p<0.01. ^aVariances are not equal. Post-hoc analysis will be labeled by the following if significant: ¹HIV-seronegative versus non-HAND;²HIV-seronegative versus HAND; ³non-HAND versus HAND.
