Objective: We investigated the relationship of standardized summary measures of verbal fluency (VF), visual naming (VN), sentence repetition (SR) and auditory comprehension (AC) as well as the verbal comprehension (VC), perceptual organization (PO), working memory (WM) and processing speed (PS) components of the WAIS-III to recall level during early, intermediate and late trial phases of the Serial Digit Learning Test, eight digit form (SDL8). Method: The VF, VN, SR, and AC spoken language variables were analyzed together in a principal component analysis that produced four orthogonal factors. The VC, PO, WM and PS components of the WAIS-III were computed with all 14 subtests based on raw scores. Factor scales were computed separately for each variable set. The factor scores for the linguistic, intellectual and memorial variables were refactored as a single group of measures. Results: A five factor solution was obtained that explained 84.56% of the variance. SDL8 early trials...
