Feedback about gaze position improves saccade efficiency



When searching for an unknown number of noisy targets in a limited time, looking at uncertain locations is more efficient than looking at locations with a high probability of the target. Previously, we showed that immediate saccadic feedback that revealed the true identity of a noisy stimulus was effective in improving saccade efficiency (Verghese, Ghahghaei, 2013). However, the stimuli in that task were not limited by visibility, and the feedback artificially removed any ambiguity about the identity of the stimulus as soon as a saccade landed at that location. Here we examine if the increase
