Judgments of Simple Geometric Figures by Children

Abstract

In order to compare perceptual visual performance of brain-damaged children and normal children, a series of perceptual studies was undertaken. Modified paired-comparison judgments were obtained from the following groups: (1) normal (kindergarten through fourth grades), (2) pre-school cerebral palsied, (3) two special classes of brain-damaged, (4) emotionally disturbed children, and (5) retarded adults (MA 5 through 11). Errors and types of error were related to age, IQ, clinical group, MA level, etc. Developmentally speaking the decline of left-right reversal errors is most striking. Organic involvement relates more to type than to sheer frequency of error. Relevant literature is discussed in relation to the findings.
