This study investigated the utility of considering Digits Forward (DF) and Digits Backward (DB) as separate components of the Wechsler Adult Intelligence Scale‐Revised (WAIS‐R). Protocols of WAIS‐Rs, Peabody Picture Vocabulary Tests‐Revised (PPVT‐Rs), and Standard Progressive Matrices (SPMs) were examined ( N = 50). Pearson correlations of Forward and Backward digit repetition and scores from PPVT‐Rs and SPMs were calculated. Repetitions of DF were correlated significantly ( p < .01) with SPM performance. Repetitions of DB were correlated significantly with performance on the PPVT‐R ( p < .02), although a stronger correlation was obtained between DB and SPM performance ( p < .001). These findings indicate that although DF and DB tasks are related, the combination of these tasks into a single score might obscure important information.
