Behavioral and electrophysiological evidence is presented suggesting that, in visual search for feature singleton targets, multidimensional signals are integrated at a preselective stage of processing. Observers searched for a target that was consistently defined by the same features, but differed from the variable context either nonredundantly by one or redundantly by two dimensionally different features. The behavioral results showed reaction time redundancy gains and evidence of coactive…

Attending to multiple objects relies on both feature- and dimension-based control mechanisms: Evidence from human electrophysiology
It is revealed that participants’ ability to enumerate multiple targets was remarkably influenced by inter-target relationships, with fastest responses for sF trials, slowest responses for dD trials, and responses of intermediate speed for dFsD trials.
Target discrimination delays attentional benefit for grouped contexts: An ERP study
The results show that visual search tasks induce an accelerated attention deployment after homogeneous contexts, however with a delay after target discrimination compared to less demanding target detection.
Early Visual Processing of Feature Saliency Tasks: A Review of Psychophysical Experiments
The psychophysical experiments which have been published in the last decades are reviewed to indicate how the low-level salient features are processed in the early visual cortex and extract the most important and basic information of the visual scene.
Multisensory Decisions: the Test of a Race Model, Its Logic, and Power
The use of separate multisensory signals is often beneficial. A prominent example is the speed-up of responses to two redundant signals relative to the components, which is known as the redundant
Neural differences between chromatic- and luminance-driven attentional salience in visual search
Speeded PCN latencies for stimuli that combine color and Luminance signals compared to stimuli that contain luminance alone demonstrate that color and luminance channels are integrated during pre-attentive visual processing, before top-down allocation of attention is triggered.
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
Contributions of Intraindividual and Interindividual Differences to Multisensory Processes
Differences in the brain networks that support behavioral benefits during un isensory versus multisensory motion detection are highlighted and provide an important view into the functional dynamics within neuronal networks underpinning intraindividual performance differences.
Abnormal alpha modulation in response to human eye gaze predicts inattention severity in children with ADHD
Highlights • In response to the human eye gaze, compared with TD children, ADHD children showed a decreased alpha lateralization.• The attenuation of alpha modulation in ADHD children was mainly


Perceptual Basis of Redundancy Gains in Visual Pop-out Search
The present study combined mental chronometry with electrophysiological markers that reflect purely preattentive perceptual plus response selection-related (stimulus-locked lateralized readiness potential [LRP]), or purely response production-related processes (response-locked LRP).
Redundancy gains in pop-out visual search are determined by top-down task set: behavioral and electrophysiological evidence.
It is concluded that redundant-signals effects in pop-out visual search are not driven by bottom-up salience but are instead strongly dependent on top-down task set.
Top-down dimensional weight set determines the capture of visual attention: evidence from the PCN component.
The results show that both high (vs. low) distracter expectancy and experiencing a distracter on the previous trial speed up the timing of the target-elicited PCN, which unambiguously demonstrates that preattentive vision is top-down modifiable.
Overriding stimulus-driven attentional capture
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.
Selective manipulation of target identification demands in visual search: the role of stimulus contrast in CDA activations.
There is direct evidence that CDA activations provide a useful tool to estimate the amount of postselective recurrent processing recruited to extract detailed object information from vSTM.

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.
Dynamic Weighting of Feature Dimensions in Visual Search: Behavioral and Psychophysiological Evidence
Dimension-based accounts of visual search and selection have significantly contributed to the understanding of the cognitive mechanisms of attention. Extensions of the original approach assuming the
Visual search for singleton feature targets across dimensions: Stimulus- and expectancy-driven effects in dimensional weighting.
Findings confirm that top-down dimensional set modulates stimulus-driven dimension processes in the detection of pop-out signals.
Electrophysiological markers of visual dimension changes and response changes.
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.
Electrophysiological correlates of feature analysis during visual search.
The overall pattern of results was consistent with guided search models in which preattentive stimulus information is used to guide attention to task-relevant stimuli.
