Explored the effects of age, education, and IQ on Hooper Visual Organization Test (VOT) scores and age-related norms for psychiatric patients. Ss were 211 male, veteran, psychiatric inpatients, grouped into six age decades, who were administered routinely the VOT and Shipley Institute of Living Scale plus other tests upon admission. Analyzing the relation between age decade and VOT, a one-way analysis of variance produced an F significant at the .001 level. An intercorrelation matrix for all the study variables disclosed that age, IQ, and education all were correlated significantly with VOT scores, as well as with each other, except for IQ and age. However, a multiple regression analysis revealed that only age and IQ accounted for significant amounts of the variance in VOT scores. Thus, these results argue for the use of age-related norms as well as norms that correct for IQ.
