An intact eye-movement system is not required to generate inhibition of return.

AI is unable to make eye-movements and has a deficit of reflexive attention. Here, we demonstrate that despite these deficits AI exhibits inhibition of return (IOR) for peripherally cued objects and locations. These data suggest that an intact oculomotor system is not required for the generation of either object-based or location-based IOR and are consistent with the view that the early, facilitatory effects of peripheral cues and late IOR effects are mediated by different mechanisms.
