Abstract
The present study related visual processing, as indicated by eye movements, to performance accuracy on coincidence-anticipation tasks. Three age groups were tested on a coincidence-anticipation task and their eye movements recorded. Three levels of response were administered under three levels of stimulus speed. A MANOVA indicated that both eye tracking and coincidence-anticipation varied among the age groups and with stimulus speed, although in different directions. Eye tracking error decreased with increasing age but only the coincidence-anticipation response accuracy of the youngest group appeared to be less accurate than that of the adults. Eye tracking error also decreased with decreasing stimulus speed but coincidence-anticipation performance was least accurate at the slow speed. Coincidence-anticipation error was the major contributor to performance differences with changes in the type of response. This study was completed in partial fulfillment of the Ph. D. degree at the University of Illinois under the direction of Dr. Marjorie Souder.
