Covert Attention and Saccadic Eye Movements
2005In normal vision the eyes make overt saccadic eye movements several times each second. We have a good understanding of how saccadic targets are selected, particularly in visual search and in reading. Visual processing is enhanced at the saccade destination before the movement itself occurs, and this peripheral preview assists the smooth uptake of ...

Covert attention modulates saccadic performance, e.g., the abrupt onset of a task-irrelevant visual stimulus grabs attention as measured by a decrease in saccadic reaction time (SRT). The attentional advantage bestowed by the task-irrelevant stimulus is short-lived: SRT is actually longer ∼200 ms after the onset of a stimulus than it is when no ...

Covert shifts and inhibition of return in saccadic and manual responses
2012In recent, unpublished studies of our institute, we adopted the experimental design of Deubel and Schneider [1996, Vision Research, 36(12), 1827-1837], to assess the effects of covert shifts on saccadic latency. Contrary to the results of the original experiment, we found slower reactions to target stimuli presented at covertly attended locations.

The neurology of saccades and covert shifts in spatial attention: an event-related fMRI study.
Brain : a journal of neurology, 2000Visual neglect occurs most frequently and persistently after lesions that include the right supramarginal gyrus (SMG), a part of the inferior parietal lobule. Patients with this syndrome make very few saccades to the left, and show abnormal performance on tasks in which they must covertly shift their attention to the left, suggesting that the right SMG

Cortical Indexes of Saccade Planning Following Covert Orienting in 20‐Week‐Old Infants
Infancy, 2001AbstractThis study examined scalp‐recorded, event‐related potential (ERP) indexes of saccade planning in 20‐week‐old infants. A spatial cuing procedure was used in which the infants were presented with a central fixation stimulus and a peripheral cue. A peripheral target followed the cue on the ipsilateral or contralateral side of the cue.

Remote distractor effects in saccadic, manual and covert attention tasks
2012The Remote Distractor Effect (RDE) is a robust phenomenon where a saccade to a lateralised target is delayed by the appearance of a distractor in the contralateral hemifield (Walker, Kentridge, & Findlay, 1995). The main aim of this thesis was to test whether the RDE generalises to response modalities other then the eyes.
