TLDR
Electrophysiological evidence that words presented during the attentional blink period are analysed to the point of meaning extraction, even though these extracted meanings cannot be reported 1–2 s later provides a demonstration of the modularity of human brain function.Abstract:
After the detection of a target item in a rapid stream of visual stimuli, there is a period of 400-600 ms during which subsequent targets are missed. This impairment has been labelled the 'attentional blink'. It has been suggested that, unlike an eye blink, the additional blink does not reflect a suppression of perceptual processing, but instead reflects a loss of information at a postperceptual stage, such as visual short-term memory. Here we provide electrophysiological evidence that words presented during the attentional blink period are analysed to the point of meaning extraction, even though these extracted meanings cannot be reported 1-2s later. This shows that the attentional blink does indeed reflect a loss of information at a postperceptual stage of processing, and provides a demonstration of the modularity of human brain function.read more

Towards a cognitive neuroscience of consciousness: basic evidence and a workspace framework.
TL;DR: This introductory chapter attempts to clarify the philosophical, empirical, and theoretical bases on which a cognitive neuroscience approach to consciousness can be founded and proposes a theoretical framework that synthesizes those facts: the hypothesis of a global neuronal workspace.

A taxonomy of external and internal attention.
TL;DR: A taxonomy based on the types of information that attention operates over--the targets of attention is proposed, providing an organizing framework that recasts classic debates, raises new issues, and frames understanding of neural mechanisms.

Event-related potential studies of attention
TL;DR: This article reviews some of the recent ERP studies of attention, focusing on studies that isolate the operation of attention in specific cognitive subsystems such as perception, working memory, and response selection.

Predicting the orientation of invisible stimuli from activity in human primary visual cortex
John-Dylan Haynes,Geraint Rees +1 more
TL;DR: It is shown that even at conventional resolutions it is possible to use fMRI to obtain a direct measure of orientation-selective processing in V1 and to successfully predict which one of two oriented stimuli a participant was viewing, even when masking rendered that stimulus invisible.

Capacity limits of information processing in the brain
René Marois,Jason Ivanoff +1 more
TL;DR: A review of the neurobiological literature suggests that the capacity limit of VSTM storage is primarily localized to the posterior parietal and occipital cortex, whereas the AB and PRP are associated with partly overlapping fronto-parietal networks.

Reading senseless sentences: brain potentials reflect semantic incongruity

TL;DR: In a sentence reading task, words that occurred out of context were associated with specific types of event-related brain potentials that elicited a late negative wave (N400).

Temporary suppression of visual processing in an RSVP task: an attentional blink? .
TL;DR: The authors found that the presentation of stimuli after the target but before target-identification processes are complete produces interference at a letter recognition stage, which may cause the temporary suppression of visual attention mechanisms observed in the present study.

TL;DR: Results of Experiments 3-5 confirmed that AB is triggered by local interference from immediate posttarget stimulation and showed thatAB is modulated by the discriminability between the 1st target and the immediately following distractor.

Short-Term Conceptual Memory for Pictures.
TL;DR: The results, taken together with those in 1969 of Potter and Levy for slower rates of sequential presentation, suggest that on the average a scene is understood and so becomes immune to ordinary visual masking within about 100 msec but requires about 300 msec of further processing before the memory representation is resistant to conceptual masks from a following picture.
