Investigated the effects of age and IQ on the Tactual Performance Test (TPT) with 117 normal S s divided into three IQ ranges (91‐111, 112‐122, 123‐139) and four age ranges (20‐29, 30‐39, 40‐49, 50‐60). The high percentage of older S s classified as brain‐damaged by Reitan's suggested cut‐off scores indicated the need for age adjusted cut‐offs. A revised cut‐off score for total time of 17.7 minutes for the 30‐49 age range and 21.7 minutes for the 50‐60 age range was suggested. A revised cut‐off score for memory of 5 or less for the 20‐39 age range, 4 or less for the 40‐49 age range, and 3 or less for the 50‐60 age range was suggested. A cut‐off score for location of 3 or less for the 20‐29 age range, 2 or less for the 30‐49 age range, and 1 or less for the 50‐60 age range was suggested. Examination of preferred and nonpreferred hand times on the TPT showed that either a simple difference or a ratio of the two scores could be used to establish normative scores unaffected by age or IQ.
