Chapman and Wedell (1972) examined the relationship between reversal errors in children's handwriting and perceptual-motor abilities in a group of children aged 7.5 to 85 years. The Perceptual Quotients of the Frostig Developmental Test of Visual Perception (DTVP) (FroStig, 1964) -a test designed to measure the specific visual percC[)[ual skills of eye-hand coordination, figureground perception, form constancy, position in space, and spatial relations -were significantly lower in the group of children with reversal errors. Among the subtests, only the Position in Space scores demonstrated statistically significJm differences between children with and without reversal errors However, the reliability of the individual subtests on the Frostig is inadequate for in terpreta tion
