Is covert spatial orienting embodied or disembodied cognition? A historical review

Abstract

The possible relations between eye movements and shifts of attention are considered in the context of the contemporary proposal of embodied cognition. The focus of this historical review is Klein’s oculomotor readiness hypothesis for how visuospatial attention might be allocated when under endogenous control. When eye movements are actually executed, attention shifts in advance of these movements. But when eye movements are prepared but not executed, shifts of attention are not observed. Conversely, when attention is allocated endogenously and covertly to a location in space, eye movements to that location are not prepared. These findings suggest that covert spatial orienting when under endogenous control is more dis-embodied than embodied cognition.
