Visual attention and response selection are limited in capacity. Here, we investigated whether visual attention requires the same bottleneck mechanism as response selection in a dual-task of the psychological refractory period (PRP) paradigm. The dual-task consisted of an auditory two-choice discrimination Task 1 and a conjunction search Task 2, which were presented at variable temporal intervals (stimulus onset asynchrony, SOA). In conjunction search, visual attention is required to select… 
Visual and central attention share a capacity limitation when the demands for serial item selection in visual search are high
Evidence is provided that visual and central attention share a common capacity limitation when conjunction search relies strongly on serial item selection, indicating that both search tasks may require central attention.
More insight into the interplay of response selection and visual attention in dual-tasks: masked visual search and response selection are performed in parallel
It is concluded that in general, response selection and visual attention rely on distinct capacity limitations, and neither the response selection difficulty in the auditory Task 1 (i.e., two-choice vs. four-choice) nor the type of presentation of the search display in Task 2 (not masked vs. masked) impaired parallel processing of response selection or conjunction search.
Visual search proceeds concurrently during the attentional blink and response selection bottleneck.
The results suggest that the nature of the concurrent visual search process is a determinant responsible for the dynamic relationship between perceptual attention deployed for visual search and central attention needed for working memory encoding and response selection.
Dual task interference on early perceptual processing
It is argued that the results, in light of previous studies, show that central processing of a first target, responsible for the classical PRP effect, also interferes with early perceptualprocessing of a second target.
Saccadic eye movements in dual tasking: No impairment of spatial planning, but delayed execution of saccades
The manual response rather than the response selection process of the auditory–manual task led to a delay of saccade execution, but not to an impairment of the spatial planning of the saccades trajectory.
Human electrophysiology reveals delayed but enhanced selection in inhibition of return
It is demonstrated here that an electrophysiology index of visual selection-the N2pc component-is delayed but enhanced at the cued than uncued location, and this enhancement in the N2PC amplitude predicts reduction in the behavioral IOR effect.
Multitasking in aging: ERP correlates of dual-task costs in young versus low, intermediate, and high performing older adults
Between‐subject differences inDual‐task interference can be explained in terms of individual differences in selection of an appropriate response in dual‐task situations.
Psychopathy is associated with an exaggerated attention bottleneck: EEG and behavioral evidence from a dual-task paradigm.
Findings suggested that individuals higher on psychopathy exhibit an exaggerated bottleneck which produces intense and long-lasting interference, impacting all information processing and partially contributing to their maladaptive behavior.
The central locus of self-prioritisation
In the present four experiments, the well-established psychological refractory period paradigm together with the locus of slack and the effect propagation logic to pinpoint the source of the self-prioritisation effect converge on the notion that the SPE has its source in a capacity-limited stage of central processing.
A Multinomial Processing Tree inferred from age-related memory-error probabilities: Possibility of inferring more if response times were available
Abstract Use of Multinomial Processing Tree (MPT) models is illustrated by fitting one to data of Dhir (2017). Her experiment examined age and association type in a paired-associate recall task. Age


Are processing limitations of visual attention and response selection subject to the same bottleneck in dual-tasks?
Investigation of 2 dual-task experiments of the psychological refractory period type revealed concurrent performance of visual search to both tone and color in Task 1’s response selection, suggesting visual attention is not subject to the response selection bottleneck.
Controlling spatial attention without central attentional resources: Evidence from event-related potentials
The present study examined whether the control of spatial attention requires central attentional resources using a modified Psychological Refractory Period paradigm. We varied across experiments

The results confirm that although selection of motor responses constitutes a processing bottleneck, the control of visual attention operates independently of this bottleneck.
The effect of task order predictability in audio-visual dual task performance: Just a central capacity limitation?
This set of findings complements classical as well as advanced versions of the central bottleneck model by providing electrophysiological evidence for modulations of both perceptual and motor processing dynamics that, in summation with central capacity limitations, give rise to the behavioral PRP outcome.
A psychological refractory period in access to visual short-term memory and the deployment of visual-spatial attention: multitasking processing deficits revealed by event-related potentials.
The results suggest that central processing leading to the PRP effect interferes with the deployment of visual-spatial attention and delays encoding into visual short-term memory (as indexed by the SPCN onset latency).

A component of the event-related potential waveform, the N2pc wave, was used as a continuous measure of the allocation of attention to possible targets in the search arrays to support models of attention that posit serial processing in demanding visual search tasks.
Dissociations and dependencies between speed and accuracy: Evidence for a two-component theory of divided attention in simple tasks
Abstract Previous work has amply demonstrated divided attention “costs” both in single-task multistimulus visual processing and in performance of multiple simple tasks; however, the relationship
Visual search strategies are indexed by event-related lateralizations of the EEG
The results suggest that target attributes alone cannot dissociate between different search strategies but showed that efficient as well as less efficient processes can be utilised for the same targets proposing that processing demands are determined by the inter-relation of target and the distractors.
The Posterior Contralateral Negativity as a Temporal Indicator of Visuo-Spatial Processing
Abstract. The temporal segmentation of the processing stream between stimulus and response is a declared aim of many EEG-studies on cognitive processing. This goal, however, can only be reached when
Attention to Features Precedes Attention to Locations in Visual Search: Evidence from Electromagnetic Brain Responses in Humans
It is suggested that target detection in visual search begins with the detection of task-relevant features, which then allows spatial attention to be allocated to the location of a likely target, which in turn allows the target to be positively identified.
