Eye movements during coincidence-anticipation performance

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.
