A current theory of attention deficit/hyperactivity disorder (ADHD) implicates a dysfunction in working memory as a significant factor in ADHD. The Working Memory Indexes of the Wechsler Adult Intelligence Scale--Third Edition (WAIS-III; The Psychological Corporation, 1997a) and the Wechsler Memory Scale--Third Edition (WMS-III; The Psychological Corp -oration, 1997b) were used to evaluate this theory. Seventy adults clinically diagnosed with ADHD (mean age = 25) and who were previously administered the WAIS-III and WMS-III were reviewed to determine the association between working memory and ADHD symptomology. The respondent was asked to estimate the frequency of occurrence of ADHD symptoms by completing the Brown ADD Scales (Brown, 1996). Results indicated no significant relationship between working memory and self-reported symptoms, although the Working Memory Indexes of the WAIS-III and the WMS-III were significantly correlated. Implications for current ADHD theory and suggestions for future research were discussed.

The interference condition of the Brown-Peterson task and the auditory consonant trigrams test was designed to evaluate working memory in that it required a division of attentional processes to complete two cognitive tasks. However, the specific cognitive functions contributing to the performance of this interference task have yet to be determined. The objective of this study was to determine what other tasks are comparable to the Brown-Peterson task and conduct an exploratory factor analysis that included the measures from the Brown-Peterson task and other neuropsychological measures. A neuropsychological battery was administered to younger participants (n=107, mean age=20.83) and older participants (n=93, mean age=70.14). Factor analysis yielded a two-factor solution. Performance after the intervening serial subtraction task loaded on an auditory/visual working memory and complex attention factor and had common loadings with working memory subtests of the WAIS-III and the spatial span subtest of the WMS-III. Results suggest that the performance after the intervening serial subtraction task evaluates dual information processing, complex attention, and working memory.
