ABSTRACT
The article examines the effectiveness of a new operant procedure for evaluating the performance of severely impaired children on a task involving differential visual acuity. The efforts to evaluate their visual perception are hampered by extreme procedural difficulties due to their inability to respond in certain procedures and the disruption of the children's behavior. The mean selective performance for the in focus image of the children with glasses was sixty-nine percent and sixty-four percent without eyeglasses. The method is essential in assessing the subjective visual acuity performance in such children with and without corrective lenses.
