The Neural Fate of Consciously Perceived and Missed Events in the Attentional Blink
Cognitive models of attention propose that visual perception is a product of two stages of visual processing: early operations permit rapid initial categorization of the visual world, while later attention-demanding capacity-limited stages are necessary for the conscious report of the stimuli. Here we used the attentional blink paradigm and fMRI to neurally distinguish these two stages of visio...
متن کاملPersisting Attentional Set 1 IRRELEVANT TARGETS PRODUCE AN ATTENTIONAL BLINK Previous Attentional Set Can Induce an Attentional Blink with Task-Irrelevant Initial Targets
Identification of a second target is often impaired by the requirement to process a prior target in a rapid serial visual presentation (RSVP). This is termed the attentional blink. Even when the first target is task-irrelevant an attentional blink may occur providing this first target shares similar features with the second target (contingent capture). An RSVP experiment was undertaken to asses...
متن کاملDelayed attentional engagement in the attentional blink.
Observers often miss the 2nd of 2 visual targets (first target [T1] and second target [T2]) when these targets are presented closely in time; the attentional blink (AB). The authors hypothesized that the AB occurs because the attentional response to T2 is delayed by T1 processing, causing T2 to lose a competition for attention to the item that follows it. The authors investigated this hypothesi...
متن کاملUnmasking the attentional blink.
When asked to identify 2 visual targets (T1 and T2 for the 1st and 2nd targets, respectively) embedded in a sequence of distractors, observers will often fail to identify T2 when it appears within 200-500 ms of T1--an effect called the attentional blink. Recent work shows that attention does not blink when the task is to encode a sequence of consecutive targets, suggesting that distractor inter...
متن کاملPhonological Attentional Blink 1 Running Head: Phonological Attentional Blink Effects of Phonological Length on the Attentional Blink for Words
People are severely limited in the rate they can identify and report visual events presented in rapid succession. This has been the focus of research on the attentional blink (AB) which is a deficit in the ability to report a second target appearing within half a second of a correctly identified first target (T1). The AB may reflect limitations for consolidating visual stimuli into working memo...
