Most of the studies examining handwriting and perceptual-motor components of performance have been correlational Authors have assumed that if there is a correlation between performance on the component and handwriting, that problems in the component underlie the handwriting problem, and that remediation of the component will result in improvement in handwriting. Although rcsearch has not shown these assumptions to be incorrect, the correlational type of resear·ch does not allow for these conclusions for scveral reasons. First, correlation does not mean causation. Thus, if children who have problems in visuospatial abilities also have problems in handwriting, it does nor mean that the visuospatial deficit causes or underlies the handwriting problem, because another variable might affect both visuospatial ability and handwriting. Second, remediation of the visuospatial problems mayor may not result in improved handwriting. Additional research is needed to directly examine this assumption. In their examination of the relationship between kinesthesia and writing, Laszlo, Bairstow, and colleagues have studied the effects of kinesthetic training on writing, and have proVided models
for this type of needed research (e.g., Laszlo & I3airstow, 1983). Their studies provide preliminary support for the assumption that improving kinesthetic perception will result in improved writing.
