This project is developing a computer-based system for the early detection and remediation of dyslexia. This system incorporates animated color graphics, digital audio recording, and a touch-sensitive display. A child using this system receives recorded verbal instructions while watching a video display and responds by touching various images on the screen.In Phase I the investigators are developing a prototype system, programming the operating software, and preparing a simple demonstration procedure to test the acceptance of the system by children. Phase II will develop a series of test programs for diagnosing dyslexia and providing remediation. The performance of the test programs will be evaluated in Phase 11 by direct comparison with the methods used at the Cortical Function Laboratory, Massachusetts General Hospital, and the Carroll School for Dyslexic Children in Lincoln, Massachusetts. If the effectiveness of the computer techniques can be demonstrated, an enterprise to deliver these services on a large scale will be developed.National Institute Of Child Health And Human Development
