A fundamental task for the visual system is to determine where to attend next. In general, attention is guided by visual saliency. Computational models suggest that saliency values are estimated through an iterative process in which each visual item suppresses each other item's saliency, especially for those with close proximity. To investigate this proposal, we tested the effect of two salient distractors on visual search for a size target. While fixing the target-to-distractor distance, we…

Visual search.
This article reviews major theories of visual search, the ways in which preattentive information is used to guide attentional allocation, the role of memory, and the processes and decisions involved in its successful completion, and concludes by summarizing the current state of knowledge.
Enhancement and suppression in the visual field under perceptual load
Estimation of the distribution of load-induced distractor suppression and task-relevant enhancement in the visual field using steady-state visual evoked potentials in conjunction with time-domain event-related potentials revealed a significant increase in N1 amplitude under high load.
Guided search through memory
ABSTRACT In “hybrid” search, observers search a visual display for any of several targets held in memory. It is known that the contents of the memory set can guide visual search (e.g., if the
Hybrid search in the temporal domain: Evidence for rapid, serial logarithmic search through memory
In hybrid search, observers memorize a number of possible targets and then search for any of these in visual arrays of items. Wolfe (2012) has previously shown that the response times in hybrid
The quest for the integration of visual saliency models in objective image quality assessment: A distraction power compensated combination strategy
The combination strategy of saliency and IQMs is revisited and a new strategy taking into account the distraction power of local distortions is proposed, showing that the proposed combination strategy consistently outperforms the conventionally used linear combination strategy.

It is demonstrated that the added value of saliency in image quality metrics can be optimised by taking into account the interactions between saliency and visual distortion, and the deviation of fixation deployment due to distortion can be used as a proxy for the prediction of image quality.

A refined methodology for reliably collecting eye-tracking data is proposed, which essentially eliminates bias induced by each subject having to view multiple variations of the same scene in a conventional experiment.

A saliency-based search mechanism for overt and covert shifts of visual attention
A detailed computer implementation of a saliency map scheme is described, focusing on the problem of combining information across modalities, here orientation, intensity and color information, in a purely stimulus-driven manner, which is applied to common psychophysical stimuli as well as to a very demanding visual search task.
Context and competition in the capture of visual attention
Investigating distractor-related costs in visual search across several manipulations of temporal context shows that search for a target in the presence of a salient distractor also produces RF-scaled costs when the features defining the target and distractor do not vary from trial to trial.
Searching for two feature singletons in the visual scene: the localized attentional interference effect
It is suggested that neighboring items, irrespective of whether these items are from the same or different dimensions, interfere with each other in attentional selection, and that searching for two cross-dimension targets may engage a process of dimension switching to effectively solve the ambiguity of each item.
A neural basis for visual search in inferior temporal cortex
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.
Perceptual selectivity for color and form

Three visual-search experiments tested whether the preattentive parallel stage can-selectively guide the attentive stage to a particular known-to-be-relevant target feature and revealed that selectivity depends on the relative discriminability of the stimulus dimensions.
Neural mechanisms of selective visual attention.
The two basic phenomena that define the problem of visual attention can be illustrated in a simple example and selectivity-the ability to filter out un­ wanted information is illustrated.
A Dissociation Between Attention and Selection
In two spatial cuing experiments, it was found that it was possible to restrict processing of attended stimuli to task-relevant dimensions and this new evidence supports two novel conclusions: (a) Selection involves more than the focusing of attention per se; and (b) task expectations play a key role in determining the depth of processing of the elementary feature dimensions of attended stimulus.

This paper reviews the visual search literature and presents a model of human search behavior, a revision of the guided search 2.0 model in which virtually all aspects of the model have been made more explicit and/or revised in light of new data.
Responses of neurons in inferior temporal cortex during memory-guided visual search.
The results support a "biased competition" model of attention, according to which objects in the visual field compete for representation in the cortex, and this competition is biased in favor of the behaviorally relevant object by virtue of "top-down" feedback from structures involved in working memory.

The effect of knowledge of a target for overriding stimulus-driven interference in simple search tasks and compound search tasks is examined in terms of their applicability to existing models and the limitations of top-down penetrability of a feature processing stage.
