Abstract
|
|
|
The present study was designed to investigate the effect of color reversal of figure-ground on visual perceptional and visuo-motor performance of cerebral palsied. The 20 spastic cerebral palsied and the 20 non-cerebral palsied children participated in the study as subjects. Perceptual subtest of perceptuo-Motor Development Diagnostic Test(PMDT) and Beery-Buktenica Development Test of Visual-Motor Intergration(VMI) were administered to assess visual perceptual and visuo-motor performance, respectively.
The main conclusions from the study were as follows.
First, the cerebral palsied subjects performed more poorly in both visual perceptional and in visuo-motor tasks than non-cerebral palsied counterparts. However, it was revealed that the relatively poor performance of the former in visual perceptual tasks were primarily due to Synthesis of Figure factor.
Second, for spastic cerebral palsied subjects, the color reversal of testing materials had the facilitating effect on visual perception but not on visuo-motor. However, any improvement as a function of color reversal was evidenced neither in visual perceptioanl nor in visuo-motor performance of the non-cerebral palsied.
Finally, presentation order did not produce significant improvement of visual perceptional and visuo-motor performance in either group. It suggest thath improvement by color reversal did not result from presentation order.
