A qualitative analysis of inaccurate responses on the Hooper Visual Organization Test

The present study investigated the types of inaccurate responses, i.e., Don't Know, Semantic, Visual (nonlinguistic), Phonological, Circumlocutory, and Perseverative, made on the Hooper Visual Organization Test by a heterogeneous sample of 68 brain-damaged and 63 substance abuse patients. The mean age of the brain-damaged and substance abuse groups were 46.0 (SD=13.5) and 43.7 (SD=12.9) yr., respectively. Analysis showed that the brain-damaged group made significantly more visual and perseverative responses than the substance abuse group. There was significantly more variance in the Visual responses than the Semantic responses for the brain-damaged group. The authors conclude that visuospatial ability is the primary factor for successful performance on this test.
