Performance on the Russell (1975) revision of the Wechsler Memory Scale and the Digit Span subtest of the Wechsler Adult Intelligence Scale by subjects with lateralized anterior and posterior lesions was investigated. Subjects were right handed males who were selected from a pool of subjects who had been referred for, and completed neuropsychological testing. Subjects were selected whose brain lesions were identified on the basis of neurodiagnostic tests as being lateralized to either the left or right hemisphere and restricted to either the anterior or posterior side of the central sulcus. Subjects with lesions resulting from trauma or with identified subcortical damage were excluded from the study. A normal comparison group was formed of subjects suspected of having neurological damage and referred for neuropsychological testing but who had normal neurodiagnostic examinations and tests. For each task, significant (p < .003) differences were found among the five groups. It was predicted that both the laterality and caudality of lesions would affect memory task performance. This prediction was fully supported for the logical memory task, and partially supported for the figural memory and digit span tasks. The memory task results were discussed in light of two recent models of memory functioning (Craik, 1984; Dunn, 1983). / Source: Dissertation Abstracts International, Volume: 46-12, Section: B, page: 4392. / Thesis (Ph.D.)--The Florida State University, 1985.
