TLDR
The evidence suggests that WM modulates competitive interactions between the items in the visual field to determine the efficiency of target selection, and this early guidance of attention by WM in humans is investigated.Abstract:
The deployment of visual attention can be strongly modulated by stimuli matching the contents of working memory (WM), even when WM contents are detrimental to performance and salient bottom-up cues define the critical target [D. Soto et al. (2006) Vision Research, 46, 1010―1018]. Here we investigated the electrophysiological correlates of this early guidance of attention by WM in humans. Observers were presented with a prime to either identify or hold in memory. Subsequently, they had to search for a target line amongst different distractor lines. Each line was embedded within one of four objects and one of the distractor objects could match the stimulus held in WM. Behavioural data showed that performance was more strongly affected by the prime when it was held in memory than when it was merely identified. An electrophysiological measure of the efficiency of target selection (the N2pc) was also affected by the match between the item in WM and the location of the target in the search task. The N2pc was enhanced when the target fell in the same visual field as the re-presented (invalid) prime, compared with when the prime did not reappear in the search display (on neutral trials) and when the prime was contralateral to the target. Merely identifying the prime produced no effect on the N2pc component. The evidence suggests that WM modulates competitive interactions between the items in the visual field to determine the efficiency of target selection.read more

Different states in visual working memory: when it guides attention and when it does not
Christian N. L. Olivers,Judith C. Peters,Judith C. Peters,Roos Houtkamp,Pieter R. Roelfsema,Pieter R. Roelfsema +5 more
TL;DR: Neurophysiological results provide insight into these different memory states by revealing a more intricate organization of working memory than was previously thought.

Where do we store the memory representations that guide attention
TL;DR: Recent evidence supporting the proposal that working memory representations are critical during the initial configuration of attentional control settings, but that after those settings are established long-term memory representations play an important role in controlling which perceptual inputs are selected by mechanisms of attention is reviewed.

Working memory as internal attention: Toward an integrative account of internal and external selection processes
Anastasia Kiyonaga,Tobias Egner +1 more
TL;DR: It is argued that WM and attention should no longer be considered as separate systems or concepts, but as competing and influencing one another because they rely on the same limited resource.

In competition for the attentional template: can multiple items within visual working memory guide attention?
TL;DR: Results are consistent with a distinction within VWM between representations that interact with perception and those that do not, and show that only a single VWM representation at a time can interact with visual attention.

Active suppression of distractors that match the contents of visual working memory.
Risa Sawaki,Steven J. Luck +1 more
TL;DR: This work found that the memory-matching probe elicited a Pd component, indicating that it was being actively suppressed, which suggests that sensory inputs matching the information being held in visual working memory are automatically detected and generate an "attend-to-me" signal, but this signal can be overridden by an active suppression mechanism to prevent the actual capture of attention.

Neural Mechanisms of Selective Visual Attention
Robert Desimone,John S. Duncan +1 more
TL;DR: The two basic phenomena that define the problem of visual attention can be illustrated in a simple example and selectivity-the ability to filter out un wanted information is illustrated.

TL;DR: A new theory of search and visual attention is presented, which accounts for harmful effects of nontargets resembling any possible target, the importance of local nontarget grouping, and many other findings.

On quantifying surprise: the variation of event-related potentials with subjective probability.
TL;DR: A priori probability and sequential structure appear to be independent determinants of the P300 complex, which was assessed to determine the waveform of event-related potentials elicited by task-relevant stimuli.

A neural basis for visual search in inferior temporal cortex
TL;DR: The results suggest that inferior temporal cortex is involved in selecting the objects to which the authors attend and foveate, and this area is known to be important for high-level visual processing.
