Saccade direction modulates the temporal dynamics of presaccadic attention.

ABSTRACT: Presaccadic attention enhances visual perception at the upcoming saccade target location. While this enhancement is often described as obligatory and temporally stereotyped, recent studies indicate that its strength varies depending on saccade direction. Here, we investigated whether the time course of presaccadic attention also differs across saccade directions. Participants performed a two-alternative forced-choice orientation discrimination task during saccade preparation. Tilt angles were individually titrated in a fixation baseline condition to equate task difficulty across the upper and lower vertical meridians. Sensitivity was then assessed at different time points relative to saccade onset and cue onset, allowing us to characterize the temporal dynamics of attentional enhancement.
