Pattern of performance on the tactual performance test

Abstract

This study explored the neuropsychological correlates of different performance patterns on the first two trials of the Tactual Performance Test (TPT) in normal subjects. Regression analysis showed a significant relationship between TPT pattern and neuropsychological summary scores, other TPT measures, and individual measures assessing visual-spatial skills and left-hand motor performance. A direct comparison of subjects who showed the expected pattern of improvement with reversal subjects, however, revealed differences only for other TPT measures and certain WAIS Performance subtests. These data are important because it appears that a reversal in the expected pattern of improvement on the TPT occurs fairly commonly in normals, especially those who are older and less well educated.
