Visual search is a critical skill for several daily tasks and may be compromised in patients with impaired vision. The objective of this study was to study the relationships between exploratory visual search performance (EVSP) visual field (VF) sensitivity in patients with glaucoma.

We experience the world as stable and continuous, despite the fact that visual input is overwritten on the retina with each new ocular fixation. Spatial remapping is the process that integrates select...
Visual search is the ability to detect a target of interest against a background of distracting objects. For many animals, performing this task fast and accurately is crucial for survival. Typically, ...
Microsaccades shift the image on the fovea and counteract visual fading. They are also thought to serve as an optimal sampling strategy while viewing complex visual scenes. The goal of our study was t...
Observers can focus their attention on task-relevant items in visual search when they have prior knowledge about the target's properties (i.e., positive cues). However, little is known about how negat...
In common "attention" tasks, which require stimulus-identity processing prior to the formation of a speeded key-press response, spatial priming effects depend on response repetition. Typically, the re...
The presented study investigates standardized visual cueing in reading and visual spatial task as a treatment method for spatial neglect. In a randomized controlled design patients receive...
The purpose of this research study is to examine the effects of prism adaptation or bromocriptine treatment on two visual-spatial recovery components. After a stroke, an "internal GPS", l...
This study examines methods to better predict improvement of a hidden disability of functional vision, spatial neglect, following stroke. Spatial neglect is a tendency to make visual judg...
The objective of this pilot work is to determine the role of central and peripheral visions in explicit attention processes (saccade planning) in the case of visual impairment.
Reading can be an uncomfortable and difficult task for some people. Symptoms include unpleasant somatic and perceptual effects, such as eye-strain, headache, and blurred text, despite norm...
Integration of spatial information perceived by visual and/or auditory CUES.
Methods used to take into account and incorporate spatial autocorrelation and regional variation into regression analysis models of data that has spatial dependency, and also to provide information on the spatial relationships among the variables.
A neurobehavioral syndrome associated with bilateral medial temporal lobe dysfunction. Clinical manifestations include oral exploratory behavior; tactile exploratory behavior; hypersexuality; BULIMIA; MEMORY DISORDERS; placidity; and an inability to recognize objects or faces. This disorder may result from a variety of conditions, including CRANIOCEREBRAL TRAUMA; infections; ALZHEIMER DISEASE; PICK DISEASE OF THE BRAIN; and CEREBROVASCULAR DISORDERS.
A process through which individuals encode information about their environmental CUES to facilitate SPATIAL NAVIGATION.
Cognitive disorders characterized by an impaired ability to perceive the nature of objects or concepts through use of the sense organs. These include spatial neglect syndromes, where an individual does not attend to visual, auditory, or sensory stimuli presented from one side of the body.
