The Holtzman Inkblot Technique in the assessment of organic brain damage

HIT performance of Barnes and Velez-Diaz' brain-damaged and control samples was contrasted. The results indicated good discrimination between Barnes' controls and both brain-damaged samples, but a poorer discrimination between Velez-Diaz' controls and the brain-damaged samples. This latter finding was attributed to the small N in Velez-Diaz' controls. Velez-Diaz' brain-damaged Ss showed the greatest degree of impairment of all samples, but Velez-Diaz' aged controls showed a poorer level of performance than did Barnes' brain-damaged patients.
