The two basic phenomena that define the problem of visual attention can be illustrated in a simple example. Consider the arrays shown in each panel of Figure 1. In a typical experiment, before the arrays were presented, subjects would be asked to report letters appearing in one color (targets, here black letters), and to disregard letters in the other color (nontargets, here white letters). The array would then be briefly flashed, and the subjects, without any opportunity for eye movements…

TLDR
A simple computational model is described that explains these results, and provides a framework for predicting a variety of additional neurophysiological, neuroimaging and behavioral studies of attention.
Rapid learning in attention shifts: A review
Many lines of evidence show that the human visual system does not simply passively register whatever appears in the visual field. The visual system seems to preferentially “choose” stimuli according
Processing capacity for natural scenes and objects in the human visual system
When a visual scene containing many discrete objects is presented to our retinae, only a subset of these objects will be explicitly represented in visual awareness. The number of objects accessing

TLDR
How electrophysiological methods have provided us with the necessary tools to understand the nature of the mechanisms that give rise to the effects observed in the first visual search paper is discussed.

Visual attention in spatial cueing and visual search
TLDR
An observer model is developed that combines the perceptual template model (PTM), the attention mechanisms in the PTM framework, and uncertainty of signal detection theory to provide a coherent picture regarding how visual information is selected and processed during feature search.
Competition and selection during visual processing of natural scenes and objects.
TLDR
The objects that the subjects consistently failed to report elicited a significant negative priming effect when presented in a subsequent task, suggesting that their identity was represented in high-level cortical areas of the visual system, before the corresponding neural activity was suppressed during attentional selection.
Typicality modulates attentional capture by object categories.
TLDR
The findings indicate that the extent of attentional capture toward a distractor depends on whether the distractor matches the category and typicality of one's attentional set.
Visual attention can enhance or prioritize the processing of specific stimuli over the overwhelming number of other sensory inputs by selecting spatial locations
Performance on a visual task is improved when attention is directed to relevant spatial locations or specific visual features. Spatial attention can be directed either voluntarily (endogenously) or

Publisher Summary Intuitively, vision appears to be an easy process—effortless, almost automatic, and so efficient that a simple glance at a complex scene is sufficient to produce immediate awareness

A neural basis for visual search in inferior temporal cortex
TLDR
The results suggest that inferior temporal cortex is involved in selecting the objects to which the authors attend and foveate, and this area is known to be important for high-level visual processing.

TLDR
A view in which parallel, preattentive processes serve to segment the field into separate objects, followed by a process of focal attention that deals with only one object at a time is able to account for results taken to support both discrimination-based and space-based theories.
Attention and the detection of signals.
TLDR
These results appear to provide an important model system for the study of the relationship between attention and the structure of the visual system, and it is found that attention shifts are not closely related to the saccadic eye movement system.

Role of inferior temporal neurons in visual memory. I. Temporal encoding of information about visual images, recalled images, and behavioral context.
TLDR
To determine the specific role of IT neurons in visual memory, the information conveyed in the neuronal responses about current patterns, recalled patterns, and behavioral context was measured and it was found that the waveforms of most neurons were significantly modulated by both the pattern and the context of the stimulus presentation.
Coding visual images of objects in the inferotemporal cortex of the macaque monkey.
TLDR
It is proposed that, in anterior IT, images of objects are coded by combinations of active cells, each of which represents the presence of a particular partial feature in the image.
Focal attention produces spatially selective processing in visual cortical areas V1, V2, and V4 in the presence of competing stimuli.

TLDR
Neural correlates of focal attentive processes can be observed in visual cortical processing in areas V1 and V2 as well as area V4 under conditions that require stimulus feature analysis and selective spatial processing within a field of competing stimuli.
The extent of processing of noise elements during selective encoding from visual displays
TLDR
The results indicated that the interference produced by noise letters is primarily on the response as opposed to the processing side and there is a limit to the precision of selective attention in the visual field.
A feature-integration theory of attention
TLDR
A new hypothesis about the role of focused attention is proposed, which offers a new set of criteria for distinguishing separable from integral features and a new rationale for predicting which tasks will show attention limits and which will not.
