Contribution of visual perceptual maturation to the ability to conserve.

The extent to which visual perceptual maturity contributes to intellectual efficiency, as measured by the ability to conserve, was investigated in educable mentally retarded and nonretarded children. Hypotheses that visual perceptual ability and conservational ability would be positively correlated and that children with more mature visual perceptual processes would be better able to conserve were supported. Relationships among visual perception, conservation, CA, MA, and IQ were discussed.
