Abstract
An item analysis of Bender-Gestalt error items, as measured by the Koppitz scoring system, was conducted with protocols of 541 children in Grades 2 to 5, selected as being representative of each age level therein, i.e., 7 to 11. The frequencies of each of the 30 possible Koppitz errors at each age level were examined for males, females, and a combined category, in an attempt to identify maturational changes in visual-motor perception. Data from a similarly conducted study with 6-yr.-old first graders are integrated with present findings as many problems in visual perceptual tasks for 6-yr.-olds had been alleviated considerably by age 7. Error items which tend to discriminate over age are identified, as are those items which do not discriminate beyond certain ages. Comparisons by sex were largely nonsignificant.
