Abstract:
This research study intended to investigate the visualperceptual performance of children in Hong Kong by comparing them to the accepted norms on the Developmental Test of Visual Perception-2nd edition. The research examined whether there was significant difference in child's gender, age, and grade. The normative study recruited two hundred and eight-nine children between the ages of 6 and 7 in normal primary schools in Hong Kong. Results indicated that there was a ceiling effect in eye-hand coordination, position in space and spatial relations subtests. Grade differences were found to be significant in all subtests except eye-hand coordination and visual-motor speed. On the other hand, there were no statistical difference in the test scores between boys and girls except on copying and figure-ground subtests. It is concluded that there is a strong need to ensure that norms for visual-perceptual tests are appropriate for the specific cultural groups being assessed.
