Having rejected the assumption that children meeting the criteria of "unimpaired" possess the basic perceptual skills needed to organize raw data into meaningful symbolic units, and the notion that children less adept in these skills can be categorized as "learning disabled" or "culturally disadvantaged," the Learning Research and Development Center at the University of Pittsburgh initiated a project which resulted in the Perceptual Skills Curriculum. Organized into four goals, the project determined: (1) which perceptual skills are related to reading and arithmetic at the primary level, (2) whether such skills can be trained effectively, (3) whether training can be measured in classroom behavior, and (4) ways in which the training can be implemented in the classroom. It was concluded that perceptual skills can be managed in the classroom by using an organized testing and training program which recognizes individual differences among children.
