 Motor theories and other action-based theories give a plausible account of some of attention’s instances, but they have limitations that prevent them from applying with full generality: Since movement of the eyes, or of the limbs, is always movement to a location motor theories will struggle to account for the allocation of attention on the basis of anything other than location. They therefore face the limitations that we saw when considering pure spotlight theories, of being unable to account for shifts in attention that do not correspond to differences in the location attended. Nor is it clear how motor theories should be applied to spatial attention in those sensory modalities where the orientation of the sense organs is less straightforward than it is in the visual case. The motor theory does, nonetheless, provide a plausible and well-supported account of the location-based variety of visual attention that is displayed in typical attention-lab experiments.
