Presaccadic Attention Shifts Up- and Downwards: Evidence From the Pupil Light Response.

ABSTRACT: Vision is introspectively stable, yet every eye movement moves the image of the world on the retina. The dominant view states that attention must precede saccades to prepare the brain for the postsaccadic retinal input, which ensures a stable visual experience. A recent surge of studies investigated visual asymmetries around the visual field, including asymmetries in presaccadic attention. Such studies demonstrated benefits of presaccadic attention on task performance for horizontal and downward saccades, but strikingly no such benefit was observed for upward saccades. An absence of upward presaccadic shifts would contrast the dominant view and indicate that presaccadic attention may not be necessary to ensure perceptual continuity. Here, we capitalized on the fact that the pupil light res
