title: Normative data for the Tactual Performance Test.
abstract: Investigated the effects of age and IQ on the Tactual Performance Test (TPT) with 117 normal Ss 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 Ss 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.
