Studies of the etiological factors in reading disability and approaches, generally visual-perceptual, to the problem are presented. Krippner's study presents 15 causes of reading disability and reveals poor visual-perceptual skills as the most common cause. The Olson-Mitchell-Westberg study attempts to determine the effects of visual training upon the reading ability of college students. Getman's program stresses the attainment of proficiency in basic developmental processes such as general body movement, eye movement, and visual-perceptual organization. Kephart's approach attempts to orient the child more fully to his environment in order to promote successful perceptual-motor matches. Delacato's method claims to alter the neurological organization through physical activity. Visual training has resulted in improved reading ability, but not all attempts have been successful. Optometrists generally support the visual training approach; most eye doctors see little value in it. This address encourages the proponents of both views to better define their positions, to engage in more fruitful communication, and to conduct more research studies of the effects of visual training on reading improvement. Additional studies, an appendix, and a bibliography are included. (RT)
