An attempt to evaluate the effects of individualized vision training in a group of grade-4 children who were both disabled in reading and diagnosed as having inadequate vision skills is reported. The effects evaluated include both changes in vision and the relationship of vision training to change in reading achievement. Experimental cases received vision training. Both the experimental and the control cases received four vision analyses and psychological evaluations. Thirty-one of the cases were followed through a 2-year procedure, and 22 of those cases were included in the final statistical analyses comparing experimentals with controls. The Bender Visual-Motor Gestalt Test, when scored by the Koppitz scoring system, did not predict underachievement in reading and may not be sensitive to visual-motor development at grade 4. The experimental and control groups did not differ from each other in either reading achievement or disability throughout the study. Pursuit fixations, near point of convergence, saccadic fixations, and perceptions of diagonals showed improvement with vision training. No change was noted in group mean intelligence scores. Tables, charts, references, and appendixes are included. (Author/WB) children'saggressive behavior at preschool. (DR)
