Fooling the eyes: the influence of a sound-induced visual motion illusion on eye movements.

The question of whether perceptual illusions influence eye movements is critical for the long-standing debate regarding the separation between action and perception. To test the role of auditory context on a visual illusion and on eye movements, we took advantage of the fact that the presence of an...
