Two experiments tested possible explanations for previous research demonstrating lower span of apprehension for learning disabled students. In experiment 1, the length of visual persistence was less for LD subjects, while in experiment 2, the rate of information pick-up was slower for LD subjects. (CL)

The author reviews aspects of visual integration which should be assessed in students with suspected learning problems: visually directed and monitored movements, visual tactual integrations, visual auditory language integrations, and visual systems integrations. (CL)

Cited is research which indicates that ocular motor abnormalities in children with reading difficulties are factors in the processing of visual information. (CL)
