The influence of saccades on visual masking
Visual masking is a well known phenomenon in which the visibility of a stimulus, the target, is reduced by the rapid presentation of either a subsequent or preceding stimulus, called the mask. In a typical masking paradigm participants are not allowed to move their eyes and asked to maintain fixation throughout the trial.

Inhibition of masked primes as revealed by saccade curvature
In masked priming, responses are often speeded when primes are similar to targets ('positive compatibility effect'). However, sometimes similarity of prime and target impairs responses ('negative compatibility effect'). A similar distinction has been found for the curvature of saccade trajectories.

Gain control of saccadic eye movements is probabilistic [PDF]
Saccades are rapid eye movements that orient the visual axis toward objects of interest to allow their processing by the central, highacuity retina. Our ability to collect visual information efficiently relies on saccadic accuracy, which is limited by a ...

Effects of Alzheimer’s Disease on Visual Target Detection: A “Peripheral Bias” [PDF]
Visual exploration is an omnipresent activity in everyday life, and might represent an important determinant of visual attention deficits in patients with Alzheimer’s Disease (AD).

Time course of target recognition in visual search [PDF]
Visual search is a ubiquitous task of great importance: it allows us to quickly find the objects that we are looking for. During active search for an object (target), eye movements are made to different parts of the scene.

Due to multiple factors such as fatigue, muscle strengthening, and neural plasticity, the responsiveness of the motor apparatus to neural commands changes over time.

Feature fusion reveals slow and fast visual memories [PDF]
Although the visual system can achieve a coarse classification of its inputs in a relatively short time, the synthesis of qualia-rich and detailed percepts can take substantially more time.

A new empirical challenge for local theories of consciousness [PDF]
Local theories of consciousness state that one is conscious of a feature if it is adequately represented and processed in sensory brain areas, given some background conditions.

A retinotopic attentional trace after saccadic eye movements: evidence from event-related potentials [PDF]
Saccadic eye movements are a major source of disruption to visual stability, yet we experience little of this disruption. We can keep track of the same object across multiple saccades.

Spatial contexts can inhibit a mislocalization of visual stimuli during smooth pursuit [PDF]
The position of a flash presented during pursuit is mislocalized in the direction of the pursuit. Although this has been explained by a temporal mismatch between the slow visual processing of flash and fast efferent signals on eye positions, here we show
