Summary of the experimental design.

<p>Early in the trial the monkey was centrally fixated, and stimuli appeared at different peripheral retinal positions. The monkey then made a saccade to the stimulus. At this point the stimulus was fixated, but the eye was at different positions (gaze angles). A. 8-position task: the monkey made a saccade to the stimulus immediately following its appearance. Stimuli appeared at 8 possible locations (dashed circles). B. 3-position task: the monkey performed a delayed match to sample task, either match-to-shape (top) or match-to-location (bottom). Stimuli appeared in 3 possible locations (dashed circles). For present purposes, we were interested only in the sample period (retinal position effects) or the post-saccade period (eye position effects). c. Set of shapes used.
