Two experiments compared reaction times (RTs) in visual search for singleton feature targets defined, variably across trials, in either the color or the orientation dimension. Experiment 1 required observers to simply discern target presence versus absence (simple-detection task); Experiment 2 required them to respond to a detection-irrelevant form attribute of the target (compound-search task). Experiment 1 revealed a marked dimensional intertrial effect of 34 ms for an target defined in a… 

Figures and Tables from this paper

Learning to suppress salient distractors in the target dimension: Region-based inhibition is persistent and transfers to distractors in a nontarget dimension.
TLDR
The present study showed that with same-dimension (but not with different-dimension) distractors, the acquired cueing effect persists over a 24-h break between the training and test session and takes several hundred trials to be unlearned when the distribution is changed to even in the test session.
Selecting and ignoring salient objects within and across dimensions in visual search
TLDR
This pattern argues in favor of a strong top-down influence on singleton selection that operates on dimensions rather than features in the N2, N2pc, and P3 latency ranges.
Is attention really biased toward the last target location in visual search? The role of focal attention and stimulus-response translation rules.
TLDR
The findings reveal that the costs and benefits for repeating the target location are determined by stimulus-response translation rules, with no effect of or on attention independent of these rules, and challenge the notion that location repetition effects reliably reflect attentional bias.
Saccadic repulsion in pop-out search: how a target's dodgy history can push the eyes away from it.
TLDR
It is shown that selection of a pop-out target can actually be delayed and made less accurate when the target-defining feature has recently been associated with distractor status.
The effect of search mode on dimension weighting
  • T. Kumada
  • Psychology, Medicine

  • 2014
TLDR
Flanker response congruency was affected by prior-knowledge suggesting that the dimension weighting correlated with attentional focusing to targets, and inter-trial dimensional priming was not affected by the search mode.
A search order lost effect: Ignoring a singleton distractor affects visual search efficiency
  • T. Kumada

TLDR
Results suggest that the search order lost effect is mediated by dynamic computations involving saliency and feature maps, and an explanation of this effect is proposed.
Configuration-centered positional priming of visual pop-out search
TLDR
This chapter investigated the representations(s) underlying positional priming of visual ‘popout’ search (Maljkovic & Nakayama, 1996) and found that target locations were coded in positional short-term memory with reference to both configuration-independent and configuration-dependent representations.
Inter-trial effects in visual pop-out search: Factorial comparison of Bayesian updating models
TLDR
Consistently across experiments, it is found that the (recent) history of the response-critical property influences the initial decision bias, while repetition/switch of the target-defining dimension affects the accumulation rate, likely reflecting an implicit ‘top-down’ modulation process.

Is attention really biased toward the last target location in visual search? Attention, response rules, distractors, and eye movements
TLDR
It is revealed that different stimulus–response translation rules and distractor-processing requirements are the main reasons for the discrepancy, while demonstrating that shifts of attention intrinsically tend away from prior target locations.

Visual search for singleton feature targets across dimensions: Stimulus- and expectancy-driven effects in dimensional weighting.
TLDR
Findings confirm that top-down dimensional set modulates stimulus-driven dimension processes in the detection of pop-out signals.
Visual search for dimensionally redundant pop-out targets: Redundancy gains in compound tasks
Two visual search experiments investigated the detection of odd-one-out feature targets redundantly defined on multiple dimensions. Targets differed from the distractors in either orientation or
Response selection modulates visual search within and across dimensions.
TLDR
Effects that typically have been attributed to early top-down modulation of attentional guidance may represent effects that occur later in processing, both in search and nonsearch conditions.
Electrophysiological markers of visual dimension changes and response changes.
TLDR
The present findings strengthen the DWA by indicating a perceptual origin of dimension change costs in visual search by focusing on specific event-related brain potential components (directly linkable to perceptual and response-related processing) during a compound search task.
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.
Visual search for dimensionally redundant pop-out targets: parallel-coactive processing of dimensions is location specific.
TLDR
Three visual search experiments investigated redundancy gains for single and dual odd-one-out feature targets that differed from distractors in orientation, color, or both to suggest that there is coactivation of a common mechanism by target signals in different dimensions, that the coactivation effects are spatially specific, and that theCoactivated mechanisms are located at a preattentive, perceptual stage of processing.
Cross-trial priming of element positions in visual pop-out search is dependent on stimulus arrangement.
TLDR
Two experiments examined cross-trial positional priming in visual pop-out search and revealed reduced facilitatory and no inhibitory priming when the elements' spatial arrangement was made irregular, indicating that positional--in particular, inhibitory--priming critically depends on the configuration of the display elements across sequences of trials.
Distinct, but top-down modulable color and positional priming mechanisms in visual pop-out search
TLDR
Three experiments examined reaction time (RT) performance in visual pop-out search to support the independency of color and positional priming effects and show that these effects are top-down modulable when target position and color are predictable.
Intra- and cross-dimensional visual search for single-feature targets
TLDR
It is revealed that cross-dimensional search is at least as efficient and for some targets even more efficient than intradimensional search and the results suggest that the details of stimulus-to-response mapping are essential in comparing intra- and cross- dimensional tasks.
The N2pc component as an indicator of attentional selectivity.
  • M. Eimer
  • Psychology, Medicine

  • 1996
TLDR
It is argued that the N2pc component that is assumed to indicate attentional filtering processes during visual search tasks may reflect the attentional selection of task-relevant stimuli and that this component is also elicited when targets are presented together with just one non-target item.
