Reading disability: a discussion of visual, auditory, and linguistic factors

A case is presented in which the chief complaint of letter reversals and poor reading achievement suggests a visual or visual-perceptual problem. Analysis of the history, refraction, visual skills, and visual-perceptual test results indicates that a visual system dysfunction is not a significant factor in this case. Rather, a linguistic skills deficit is suggested by the pattern of errors exhibited on the tests. The influence of linguistic skills on several commonly used visual tests is discussed.
