Saccade curvature represents a sensitive measure of oculomotor inhibition with saccades curving away from covertly attended locations. Here we investigated whether and how saccade curvature depends on movement preparation time when a perceptual task is performed during or before saccade preparation. Participants performed a dual-task including a visual discrimination task at a cued location and...

When a distractor appears close to the target location, saccades are less accurate. However, presence of further distractor, remote from those stimuli, increases saccade response latency and improves accuracy. Explanations for this either that second, impacts directly on selection processes or merely impairs ability initiate changes time at which unaffected accessed. In order tease these two ex...

In the current study, we examined how the saccadic system responds when visual information changes dynamically in our environment. Previous studies, using the double-step task, have shown that (a) saccade plans could overlap, such that saccade preparation to an object started even while the saccade preparation to another object was ongoing, and (b) saccade plans could be cancelled before they w...

background: neurotologic signs and symptoms, especially vestibular symptoms are common in migrainous patients. involvement of the visual system in migrainures has received a great deal of attention in recent years, but the oculomotor part of the visual system has been largely ignored. the goal of this study was to investigate some parts of the central vestibular system using the oculomotor part...

When we look around and register the location of visual objects, our oculomotor system continuously prepares targets for saccadic eye movements. The preparation of saccade targets may be directly involved in the perception of object location because modification of saccade amplitude by saccade adaptation leads to a distortion of the visual localization of briefly flashed spatial probes. Here, w...

Saccade-contingent change detection provides a powerful tool for investigating scene representation and scene memory. In the present study, critical objects presented within color images of naturalistic scenes were changed during a saccade toward or away from the target. During the saccade,the critical object was changed to another object type, to a visually different token of the same object t...

When observers make a saccade across a flickering light dot at the same location, they usually perceive an array of dots (Hershberger, 1987). This phenomenon can be exploited for presenting two-dimensional images using only a single dimensional light source such as a single column of LEDs or laser projectors. In the present study, we investigated whether the perceived length of saccade-induced ...
