- Title
Is There a Greater Incidence of Color-Vision Deficiencies in Learning- Disabled Children?
- Authors

- Abstract
This article comments on the findings of studies concerning the incidence of color-vision deficiencies in learning-disabled children. According to several recent studies, color-vision deficiencies are more frequent than in the general childhood population. In particular, H.F. Sassoon and colleagues have recorded that learning-disabled children have a greater apparent incidence of what they term "blue decrement" compared to that of unaffected children when tested with the Farnsworth D-15 Panel Test. A number of other studies have also yielded results which differ from those of Sassoon and colleagues. Researcher M. Waddington, using her own screening test and the Ishihara plates, found no relation between color deficiency and achievement test scores in reading, spelling, and arithmetic, or in IQ scores. The researcher's findings imply that with some pupils in special schools, the color deficiencies are related to other medical problems, rather than being congenital.
