Saccadic eye movements are made at least 100,000 times each day. It is well known that sensitivity to visual input is suppressed during saccades; we examined whether cognitive activity (specifically, mental rotation) is suppressed as well. If cognitive processing occurs during saccades, a prime viewed in one fixation should exert a larger influence on a target viewed in a second fixation when a long rather than a short saccade separates their viewing. No such effect was found, even though the time difference between long and short saccades was effective in a no-saccade control. These results indicate that at least some cognitive operations are suppressed during saccades.
