Visual and central attention are limited in capacity. In conjunction search, visual attention is required to select the items and to bind their features (e.g., color, form, size), which results in a serial search process. In dual-tasks, central attention is required for response selection, but because central attention is limited in capacity, response selection can only be carried out for one task at a time. Here, we investigated whether visual and central attention rely on a common or on… 
The Influence of Cognitive Load on Distractor-Response Bindings
Load was manipulated by using a secondary task, which was to be carried out simultaneously with the primary task, and the influence of targeting different working memory processes (maintenance and updating) was examined by varying the time point of the presentation of the secondary task.

Within this second issue of Attention Perception and Psychophysics, papers are organized by topic, which gives me the chance to highlight four topics that were of importance to Anne Treisman during her career and that remain important, as evidenced by the interesting papers they have generated here.


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.
Concurrent deployment of visual attention and response selection bottleneck in a dual-task: Electrophysiological and behavioural evidence
It is concluded that visual attention does not require the same bottleneck mechanism as response selection in dual-tasks of the psychological refractory period (PRP) paradigm.
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.

The results showed that central attention for response selection was engaged in perceptual processing for visual search when the number of search items increased, thereby increasing the demand for serial allocation of focal attention.

The results confirm that although selection of motor responses constitutes a processing bottleneck, the control of visual attention operates independently of this bottleneck.
Shifting visual attention and selecting motor responses: distinct attentional mechanisms.
Does shifting visual attention require the same central mechanism as that required for selecting overt motor responses? In Experiment 1, Ss performed 2 tasks: a speeded manual response to a tone and
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

GS evolved out of the two-stage architecture of models like Treisman's feature integration theory (FIT), which proposed a parallel, preattentive first stage and a serial second stage controlled by visual selective attention.
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

This paper reviews the visual search literature and presents a model of human search behavior, a revision of the guided search 2.0 model in which virtually all aspects of the model have been made more explicit and/or revised in light of new data.
