Salience effects on attentional selection are enabled by task relevance.

Attention is a limited resource that must be carefully controlled to prevent distraction. Much research has demonstrated that distraction can be prevented by proactively suppressing salient stimuli to prevent them from capturing attention. It has been suggested, however, that prior studies showing evidence of suppression may have used stimuli that were not truly salient.

Evidence against the low-salience account of attentional suppression.

Do salient distractors have the power to automatically capture attention? This question has led to a heated debate concerning the role of salience in attentional control. A potential resolution, called the signal suppression hypothesis, has proposed that salient items produce a bottom-up signal that vies for attention, but that salient stimuli can be suppressed via top-down control to prevent the capture of attention. This hypothesis, however, has been criticized on the grounds that the distractors used in initial studies of support were weakly salient.

Attentional suppression of dynamic versus static salient distractors.

Attention must be carefully controlled to avoid distraction by salient stimuli. The signal suppression hypothesis proposes that salient stimuli can be proactively suppressed to prevent distraction. Although this hypothesis has garnered much support, most previous studies have used one class of salient distractors: color singletons.

Terms of debate: Consensus definitions to guide the scientific discourse on visual distraction.

Hypothesis-driven research rests on clearly articulated scientific theories. The building blocks for communicating these theories are scientific terms. Obviously, communication - and thus, scientific progress - is hampered if the meaning of these terms varies idiosyncratically across (sub)fields and even across individual researchers within the same subfield.

The Distractor Positivity Component and the Inhibition of Distracting Stimuli.

There has been a long-lasting debate about whether salient stimuli, such as uniquely colored objects, have the ability to automatically distract us. To resolve this debate, it has been suggested that salient stimuli do attract attention but that they can be suppressed to prevent distraction. Some research supporting this viewpoint has focused on a newly discovered ERP component called the distractor positivity (PD), which is thought to measure an inhibitory attentional process.

Is covert attention necessary for programming accurate saccades? Evidence from saccade-locked event-related potentials.

For decades, researchers have assumed that shifts of covert attention mandatorily occur prior to eye movements to improve perceptual processing of objects before they are fixated. However, recent research suggests that the N2pc component-a neural measure of covert attentional allocation-does not always precede eye movements. The current study investigated whether the N2pc component mandatorily precedes eye movements and assessed its role in the accuracy of gaze control.

A Critique of the Attentional Window Account of Capture Failures.

There has been a lengthy debate about whether salient stimuli have the power to automatically capture attention, even when entirely task irrelevant. Theeuwes (2022) has suggested that an attentional window account could explain why capture is observed in some studies, but not others. According to this account, when search is difficult, participants narrow their attentional window, and this prevents the salient distractor from generating a saliency signal.

The role of salience in the suppression of distracting stimuli.

Researchers have long debated whether salient distractors have the power to automatically capture attention. Recent research has suggested a potential resolution, called the signal suppression hypothesis, whereby salient distractors produce a bottom-up salience signal, but can be suppressed to prevent visual distraction. This account, however, has been criticized on the grounds that previous studies may have used distractors that were only weakly salient.

A new technique for estimating the probability of attentional capture.

Latency-based metrics of attentional capture are limited: They indicate whether or not capture occurred, but they do not indicate how often capture occurred. The present study introduces a new technique for estimating the probability of capture. In a spatial cueing paradigm, participants searched for a target letter defined by color while attempting to ignore salient cues that were drawn in either a relevant or irrelevant color.

Oculomotor suppression of abrupt onsets versus color singletons.

There is considerable evidence that salient items can be suppressed in order to prevent attentional capture. However, this evidence has relied almost exclusively on paradigms using color singletons as salient distractors. It is therefore unclear whether other kinds of salient stimuli, such as abrupt onsets, can also be suppressed.

Ten simple rules to study distractor suppression.

Distractor suppression refers to the ability to filter out distracting and task-irrelevant information. Distractor suppression is essential for survival and considered a key aspect of selective attention. Despite the recent and rapidly evolving literature on distractor suppression, we still know little about how the brain suppresses distracting information.

Covert attention is attracted to prior target locations: Evidence from the probe paradigm.

There is growing evidence that visual attention can be guided by selection history. One example of this is intertrial location priming, whereby attention is attracted to the target location from the previous trial. Most previous demonstrations of location priming have relied on manual response time effects whereby search is speeded when the target location repeats from the previous trial.

Electrophysiological Evidence for the Suppression of Highly Salient Distractors.

There has been a longstanding debate as to whether salient stimuli have the power to involuntarily capture attention. As a potential resolution to this debate, the signal suppression hypothesis proposes that salient items generate a bottom-up signal that automatically attracts attention, but that salient items can be suppressed by top-down mechanisms to prevent attentional capture. Despite much support, the signal suppression hypothesis has been challenged on the grounds that many prior studies may have used color singletons with relatively low salience that are too weak to capture attention.

Attentional suppression of highly salient color singletons.

A longstanding debate in visual attention research has been whether physically salient objects have an automatic power to capture attention. Recent evidence has supported a hybrid model. According to the signal suppression hypothesis, salient items automatically attract attention but can be proactively suppressed via top-down control to prevent attentional capture.

The development of oculomotor suppression of salient distractors in children.

There is considerable evidence that adults can prevent attentional capture by physically salient stimuli via proactive inhibition. A key question is whether young children can also inhibit salient stimuli to prevent visual distraction. The current study directly compared attentional capture in children (M = 5.

Oculomotor inhibition and location priming in schizophrenia.

Schizophrenia is widely thought to involve elevated distractibility, which may reflect a general impairment in top-down inhibitory processes. Schizophrenia also appears to involve increased priming of previously performed actions. Here, we used a highly refined eye-tracking paradigm that makes it possible to concurrently assess distractibility, inhibition, and priming.

Eye movements are not mandatorily preceded by the N2pc component.

Researchers typically distinguish between two mechanisms of attentional selection in vision: overt and covert attention. A commonplace assumption is that overt eye movements are automatically preceded by shifts of covert attention during visual search. Although the N2pc component is a putative index of covert attentional orienting, little is currently known about its relationship with overt eye movements.

Progress Toward Resolving the Attentional Capture Debate.

For over 25 years, researchers have debated whether physically salient stimuli capture attention in an automatic manner, independent of the observer's goals, or whether the capture of attention depends on the match between a stimulus and the observer's task set. Recent evidence suggests an intermediate position in which salient stimuli automatically produce a priority signal, but the capture of attention can be prevented via an inhibitory mechanism that suppresses the salient stimulus. Here, proponents from multiple sides of the debate describe how their original views have changed in light of recent research, as well as remaining areas of disagreement.

Introspective awareness of oculomotor attentional capture.

Recent research has demonstrated that observers can learn to prevent attentional capture by physically salient stimuli. One critical question is how observers learn to avoid capture, particularly in situations where they receive no direct feedback about attentional performance. One possibility is that individuals have some level of introspective awareness of capture when it occurs.

Progress and Remaining Issues: A Response to the Commentaries on.

Luck et al. (2021) reviewed evidence that observers can learn to suppress attentional capture by salient distractors. Several commentaries were written in response to this review paper, many of which raised important and interesting issues.

No identification of abrupt onsets that capture attention: evidence against a unified model of spatial attention.

Many studies have reported that spatial attention can be involuntarily captured by salient stimuli such as abrupt onsets. These involuntary shifts are often assumed to have the same effects on feature extraction as voluntary shifts: there are two different ways of moving the same attentional mechanism. According to this unified model of spatial attention, all shifts of attention should enhance the identification of attended objects.

Attentional dwelling and capture by color singletons.

Can salient stimuli-such as color singletons and abrupt onsets-involuntarily capture spatial attention? We previously reported evidence that abrupt onsets can capture attention, but the effects of this capture can become latent under easy visual search. The present experiments examined whether a similar pattern of latent capture occurs for task-irrelevant color singletons. Participants searched for a perfect circle among oval distractors.

Prior target locations attract overt attention during search.

A key question about visual search is how we guide attention to objects that are relevant to our goals. Traditionally, theories of visual attention have emphasized guidance by explicit knowledge of the target feature. But there is growing evidence that attention is also implicitly guided by prior experience.

Assessing introspective awareness of attention capture.

Visual attention can sometimes be involuntarily captured by salient stimuli, and this may lead to impaired performance in a variety of real-world tasks. If observers were aware that their attention was being captured, they might be able to exert control and avoid subsequent distraction. However, it is unknown whether observers can detect attention capture when it occurs.
