Objective: The relationship of demographic variables to performance on the Visual Form Discrimination Test (VFDT), Benton Visual Retention Test (BVRT) and the Wechsler Adult Intelligence Scale-III were examined. Method: One hundred twenty nine participants with mixed neuropsychiatric diagnoses who completed the BVRT, VFDT and WAIS-III were included; there were no exclusion criteria. Results: Factor analyses were performed separately for the items of VFDT and BVRT. Each analysis produced two components that represented the early and late sequence items for each test. VFDT item factors were examined with age and educational level. Education loaded on the VFDT_Early factor and age loaded on the VFDT_Late factor. These new factorial components were refactored with BVRT_Early (Items 1-4) and BVRT_Late (items 5-10) factorial variables that were derived in previous studies. BVRT_Early, VFDT_Early, and educational level loaded on one factor (Component 1). BVRT_Late, VFDT_Late, and age loaded on a second factor (Component 2). Components 1 and 2 were refactored a final time with the four components of the WAIS-III based on subtest raw scores. Component 1 loaded on VCI and WMI while Component 2 loaded on POI and PSI. Conclusion: Performance level on early items of VFDT and BVRT appears to increase with higher educational level, stronger verbal abilities, and better working memory, while higher performance on late VFDT and BVRT items is related to age, stronger perceptual reasoning abilities, and quicker cognitive processing speed. There appears to be a verbal construct that mediates performance on early BVRT and VFDT items. Later appearing items on both tests appear to be nonverbally mediated.
