Our eyes do not always go where we want them to go: capture of the eyes new objects
article
We make rapid eye movements to examine the world around us. Before an eye movement is made, attention is covertly shifted to the location of the object of interest. The eye typically will land at the position at which attention is directed. Here we report that a goal-directed eye movement towards an object is disrupted by the appearance of a new irrelevant object which is known to capture attention automatically. In many instances, before the eye reached the singleton target, it started moving in the direction of the new object. The eye often landed for a very short period of time (25-150 ms) near the new object. The results suggests parallel programming of two saccades: one voluntary goal-directed eye movement toward the colour singleton target and one stimulus-driven eye move-ment reflexively elicited by the appearance of the new object. Neuroanatomic structures responsible for parallel programming of saccades are discussed.
