Inside and Outside the Focus of Attention
rons and a corresponding convergence of information A wide expanse of the visual environment, typically clutas an increasing number of objects can fit within each tered with visual information, is encoded by the retinae receptive field. This confluence would seem to lead inand passed to the central visual system. How do we variably to an inseparable mixture of information from integrate and coo...
متن کاملTwo stages of visual feature binding: inside and outside the focus of attention
Despite of the fact that visual features are processed separately in specialized subsystems in the brain, our perceptual experience is of coherent objects. It has been suggested that visual attention acts as a “glue” to bind separate features--such as color, shape, size, motion, and location—into objects (Triesman & Gelade, 1980). This theory would suggest that features outside of visual attent...
متن کاملTime course of spatial and feature selective attention for partly-occluded objects.
Attention selects objects/groups as the most fundamental units, and this may be achieved by an attention-spreading mechanism. Previous event-related potential (ERP) studies have found that attention-spreading is reflected by a decrease in the N1 spatial attention effect. The present study tested whether the electrophysiological attention effect is associated with the perception of object unity ...
متن کاملTime Course of Attention Reveals Different Mechanisms for Spatial and Feature-Based Attention in Area V4
Attention can facilitate visual processing, emphasizing specific locations and highlighting stimuli containing specific features. To dissociate the mechanisms of spatial and feature-based attention, we compared the time course of visually evoked responses under different attention conditions. We recorded from single neurons in area V4 during a delayed match-to-sample task that controlled both s...
متن کاملComparing the Relationship between Focus of Attention and Attention Bias in Suicide and Non-suicide Attempters
Objective: Suicide rate is unfortunately increasing in recent years and its assessment is a must. Most studies have evaluated different factors like personality, depression, or environment in suicide attempters but cognitive functions have been overlooked in suicide attempters. The current research aimed to evaluate a kind of cognitive function, namely attention in survivors of suicide. ...
