This study aims to analyze factorial relationships among components of naming, cognition, and memory in order to facilitate integrated syndrome analysis.
These findings support the importance of joint interpretation of specific factorial naming, learning strategy, and Wechsler intelligence scale components when these measures are administered together in clinical evaluations.
The first Visual Naming factor (VN1) uniquely loaded on the CVLT Semantic Clustering Index. The second VN factor (VN2) uniquely loaded on the CVLT Serial Clustering Index. Factor scales were computed for these second order CVLT-VN components. Those factorial variables were refactored with Verbal Comprehension (VC), Perceptual Organization (PO), and Freedom from Distractibility (FFD) factorial components of the WAIS-R. The Semantic Clustering-VN1 factor uniquely loaded on the FFD component. Attention span and working memory features were associated with semantic processing. The Serial Clustering-VN2 component uniquely loaded on the VC component. Serial clustering was associated with use of over-learned verbal encoding strategies.

Our case sample included 240 clinically referred, diagnostically unselected inpatient and outpatient military veterans with mixed neuropsychiatric diagnoses. The 30 items of the Multilingual Aphasia Examination Visual Naming (VN) subtest were factored as a single group; two orthogonal factors were extracted. Factor scales based on those results were computed and re-factored separately with the Serial and Semantic Clustering indices of the CVLT.
