Motor and Tactile-Perceptual Deficits in Brain-Damaged Children

35 brain-damaged and normal Ss were matched in pairs. They were compared on motor strength, motor speed, psychomotor skill and tactile-perceptual function including finger localization, finger-tip number writing, and form recognition for preferred and non-preferred hands. Methods of inference utilized include: level of performance, pathognomic sign and performance of the preferred vs non-preferred hands. Brain-damaged children consistently performed more poorly than control children. Motor-performance measures showed greater deficits than did tests of tactile-perception. Each method of inference (level, sign, preferred vs non-preferred hand) was validated by the results. Combined use of these methods provided complementary information concerning differences in brain-damaged and normal children.
