Abstract
Participants were presented with either one diamond or one odd-colored diamond among distractors and instructed to make a saccade to fixate the target shape. They initiated eye movements to a single target faster than the odd-color target when the trial types were presented in separate blocks, consistent with results from reach-tracking experiments. Unlike reaching movements, however, when trial types were randomly mixed within a block, the initiation latencies did not homogenize. When trial types were predictably alternated, there was still no homogenization of initiation latencies. This suggests that there are different mechanisms underlying the guidance of reaching movements versus saccades, and further research is necessary to develop a full understanding of the similarities and differences between these processes.

    Each year, Brown showcases the research of nearly 200 undergraduates at our Summer Research Symposium. More than half of the student-researchers are UTRA recipients, while others receive funding from a variety of Brown-administered and national programs and fellowships. Presenters include ...
