Perceptual judgments of normal and clumsy children.

The performance of normal and clumsy children was compared on a range of measures of visuo-spatial perception. It was found that the clumsy children performed more poorly than the normal children on size-constancy judgements and area, slope, spatial position and linear length discriminations. The differences could not be explained by variations in visual acuity. These results are discussed in terms of information-processing models of motor control, and their possible implications for the assessment and treatment of clumsy children are briefly outlined.
