“…On some of the trials, a response-irrelevant color singleton (i.e., a unique color) was shown. Reaction times (RTs) were longer when the color singleton was present, suggesting that attention was captured by the irrelevant color singleton (for alternative accounts, see Folk & Remington, 1998;Jannati, Gaspar, & McDonald, 2013; for review, see Lamy, Leber, & Egeth, 2012;Theeuwes, 2010). In contrast, when observers searched for a color-defined target, there was no interference from shape distractors.…”

Search for a shape target is difficult when its shape is similar to the shape of the surrounding nontargets and easy when it is dissimilar. We asked whether interference from a salient but irrelevant color singleton depended on search difficulty as manipulated by target-nontarget similarity. We found that interference was strong in difficult searches, and the occurrence of an electrophysiological index of attentional selectivity (the N2pc component) confirmed that attention was captured by the distractor. In contrast, interference from the distractor was weak with easy searches, and the occurrence of the P component confirmed that saliency signals from the distractor were suppressed. The results suggest that attentional suppression of salient but irrelevant distractors is only possible when search is efficient (i.e., with low target-nontarget similarity), otherwise, attentional capture occurs. Further, we analyzed the Ppc component, a positivity occurring between 100 and 200 ms after stimulus onset contralateral to a salient feature discontinuity. It has been suggested that the Ppc reflects bottom-up saliency signals, but we found the Ppc to occur only when the salient stimulus was unlikely to be selected, as in efficient searches. Thus, attentional requirements modulate the Ppc component.

“…The basic assumption of these studies is that the distractors are attended in low load conditions and unattended in high load conditions. The problem is that this assumption cannot be stated a priori since it serves as the hypothesis and as the end product of the investigation of load theory, and since load theory uses the same manipulations of load, to test this assumption (see Lamy et al, 2013, for a related criticism). That is, for example, if manipulating load does not affect distractor interference it may indeed suggest that the processing of this distractor is not affected by attention, or is processed in a specific module.…”

The present paper provides a short critical review of the theory of perceptual load. It closely examines the basic tenets and assumptions of the theory and identifies major conceptual and methodological problems that have been largely ignored in the literature. The discussion focuses on problems in the definition of the concept of perceptual load, on the circularity in the characterization and manipulation of perceptual load and the confusion between the concept of perceptual load and its operationalization. The paper also selectively reviews evidence supporting the theory as well as inconsistent evidence which proposed alternative dominant factors influencing the efficacy of attentional selection.

“…Selective attention helps us overcome this limitation by enhancing the processing of prioritized events at the expense of other events. What factors determine such prioritization has been intensely debated (e.g., Awh, Belopolsky & Theeuwes, 2012;Lamy, Leber & Egeth, 2012;Theeuwes, 2010). To answer this question, researchers have attempted to characterize objects that capture attention against our will, which led them to espouse one of two opposing viewpoints.…”

Contingent Attentional Engagement: Stimulus- and Goal-Driven Capture Have Qualitatively Different Consequences

We examined whether shifting attention to a location necessarily entails extracting the features at that location, a process referred to as "attentional engagement". In three spatial-cueing experiments (N=60) we found an onset cue to capture attention both when it shared the target's color and when it did not. Yet, the effects of the match between the response associated with the cued object's identity and the responses associated with the target (compatibility effects), which are diagnostic of attentional engagement, were observed only with relevant-color onset cues. These findings demonstrate that stimulusand goal-driven capture have qualitatively different consequences: before attention is reoriented to the target, it is engaged to the location of the critical distractor following goal-driven capture, but not following stimulus-driven capture. The reported dissociation between attentional shifts and attentional engagement suggests that attention is best described as a "camera": one can shift its zoom lens without pressing the shutter-button.
