In efficient search for feature singleton targets, additional singletons (ASs) defined in a nontarget dimension are frequently found to interfere with performance. All search tasks that are processed via a spatial saliency map of the display would be predicted to be subject to such AS interference. In contrast, dual-route models, such as feature integration theory, assume that singletons are detected not via a saliency map, but via a nonspatial route that is immune to interference from cross…

No attentional capture for simple visual search: evidence for a dual-route account.

TLDR
The dual-route account for visual search suggests that the task that is being completed determines whether search is based on attentive or preattentive mechanisms, suggestive of a distinction between attentional requirements of the 2 tasks.
Dimension intertrial and cueing effects in localization: support for pre-attentively weighted one-route models of saliency
TLDR
Early effects of dimensional weighting in a spatial task are examined for, the presence of which is only predicted by the DWA and not by post-selective or dual-route accounts, and strengthens evidence for a pre-attentive origin of these effects.
Search efficiency as a function of target saliency: The transition from inefficient to efficient search and beyond.
Searching for an object among distracting objects is a common daily task. These searches differ in efficiency. Some are so difficult that each object must be inspected in turn, whereas others are so
Visually guided pointing movements are driven by the salience map.
TLDR
Modulations of salience influence yes/no target detection or left/right localization responses in manual key-press search tasks, as well as ocular or skeletal movements to the target, which supports the notion of a motor-unspecific salience map, which guides covert attention aswell as overt eye and hand movements.
Salience from the decision perspective: You know where it is before you know it is there.
TLDR
A model of detection and localization tasks based on random walk processes is proposed, which can account for the present findings and is at variance with two classes of standard models of visual search and object recognition.
Visual search.
TLDR
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.
Stimulus Saliency Modulates Pre-Attentive Processing Speed in Human Visual Cortex
TLDR
By linking the Posterior Contralateral Negativity (PCN) component to reaction time (RT) performance, this work tested one specific prediction of such salience summation models: expedited shifts of focal-attention to targets with low, as compared to high, target-distracter similarity.
Visual search for color and shape: when is the gaze guided by feature relationships, when by feature values?
TLDR
The results suggest that visual selection is preferentially biased toward the relative attributes of a search target, and participants can be pretrained to select a color target in virtue of its exact feature value.
Distractors less salient than targets capture attention rather than producing non-spatial filtering costs.
TLDR
It is concluded that reaction time interference by less salient distractors in the distractor search paradigm is a result of attentional capture in a proportion of trials, rather than an result of non-spatial filtering costs.
Size Matters: Large Objects Capture Attention in Visual Search
  • M. Proulx
  • Computer Science, Medicine

TLDR
Visual search experiments suggest that a large object can indeed capture attention in a stimulus-driven manner and independent of displaywide features of the task that might encourage a goal-directed bias for large items.

TLDR
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.
Overriding stimulus-driven attentional capture
TLDR
It is concluded that goal-directed selection of a specific known featural identity may override stimulus-driven capture by salient featural singletons and top-down selectivity is indeed possible during visual search.
Visual search for singleton feature targets within and across feature dimensions
TLDR
Three experiments investigated visual search for singleton feature targets and found that pop-out requires (or involves) knowledge of the particular dimension in which an odd-one-out target differs from the nontargets; furthermore, that knowledge is acquired through the elimination of dimensions not containing a target.

TLDR
Measurement of dimension-specific performance during detection and localization, tasks that require operation of dimensional modules and the master map, respectively, showed a dissociation between tasks in terms of both dimension-switching costs and cross-dimension attentional capture, supporting FIT's postulation that different mechanisms are involved in parallel and focal attention searches.
A saliency-based search mechanism for overt and covert shifts of visual attention
TLDR
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.
Perceptual selectivity for color and form

TLDR
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.
Does a salient distractor capture attention early in processing?
TLDR
Results suggest that, early in processing, top–down factors can exert their influence and prevent the capture of attention by a salient distractor.
Attentional capture by salient color singleton distractors is modulated by top-down dimensional set.
TLDR
Three experiments examined whether salient color singleton distractors automatically interfere with the detection singleton form targets in visual search, and revealed distracting interference to vary as a function of both the initial experience with distractors and the incentive to suppress them, suggesting that distractor interference is top-down modulable.
Intertrial target-feature changes do not lead to more distraction by singletons: Target uncertainty does
TLDR
The findings argue against the claim that singleton search relies exclusively on stimulus-driven factors and suggest that preknowledge of the target feature, when available, can guide attention.
Irrelevant singletons in pop-out search: attentional capture or filtering costs?
  • S. Becker

TLDR
The results show that the distractor only regularly captures attention when it is nonpredictive of the target position and unpredictably changes its features, which clarifies the notion of filtering costs and modifies present accounts of the distraction effect.
