Saccadic adaptation shifts the pre-saccadic attention focus

@article{citeulike:1459848, abstract = {The well-documented phenomenon of the spatial coupling between saccadic programming and the orienting of attention refers to the fact that visual attention is directed toward the location that the eyes are aiming for.
