Norms for the Controlled Oral Word Association Test (COWAT; Benton & Hamsher, 1976) have been published as summary statistics from many relatively small samples. The purpose of this study was to combine statistics from these samples to produce metanorms broken down by age, gender, and level of education. Means and standard deviations of letters F, A, and S (FAS) totals from normative samples and samples of normal controls were gathered from a wide variety of research studies and then stringently selected based on factors such as adequacy of the sample and presence of the appropriate statistics. The resulting aggregate statistics for FAS totals suggest differences may exist in verbal fluency task performance, depending on a person 's age, gender, and level of education.
1996) have presented formulas for estimating the Wechsler Memory Scale-Revised General Memory and Delayed Recall Indexes using the initial and delayed portions of only 3 subtests. The original work found nearly perfect estimates. The present study indicated excellent crossvalidation for the original formulas with correlations of .99. Over 85% of the estimated scores were within 6 points of the actual score. Using estimates from only 2 subtests rather than 3, correlations were only slightly lower with 85% of the estimated scores within 10 points of the actual scores. Age, education, diagnosis, and IQ had no effects on the accuracy of these equations. Although the initial 3 test formulas are robust, the results suggest that using only 2 subtests results in higher estimation errors, which can be used when less accurate estimates are acceptable (such as in group research).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
