TL;DR: Analyses of errors indicated that the 2nd target is frequently replaced or corrupted by the following distractor during the blink, which appears to result from both attentional and mnemonic processes.
Abstract: Observers watched for 1 or 2 colored words as targets presented in lists of distractor strings (10 items/s). Identification of 1 target (T1) temporarily reduced the accuracy of reporting a 2nd target (T2). This attentional blink (AB) effect was most pronounced when T1 and T2 occurred close together in time. Use of recognition tests (instead of recall) improved performance but did not eliminate the AB effect. The AB effect was found with both word and nonword distractors, a smaller AB effect was found with consonant string distractors, and the AB effect was substantially attenuated with strings of unfamiliar characters (a false font). Analyses of errors indicated that the 2nd target is frequently replaced or corrupted by the following distractor during the blink. The AB effect appears to result from both attentional and mnemonic processes.

TL;DR: The results imply that theories of visible persistence and visual masking must account for attentional influences in addition to lower-level effects and have practical implications for use of the temporal-integration task in the assessment of group and individual differences.
Abstract: When two visual patterns are presented in rapid succession, their contours may be combined into a single unified percept This temporal integration is known to be influenced by such low-level visual factors as stimulus intensity, contour proximity, and stimulus duration In this study we asked whether temporal integration is modulated by an attentional-blink procedure The results from a localisation task in experiment 1 and a detection task in experiment 2 pointed to two separate effects First, greater attentional availability increased the accuracy of spatial localisation Second, it increased the duration over which successive stimuli could be integrated These results imply that theories of visible persistence and visual masking must account for attentional influences in addition to lower-level effects They also have practical implications for use of the temporal-integration task in the assessment of group and individual differences

TL;DR: It was found that the magnitude and time course of activation within the anterior cingulate, medial prefrontal cortex, and frontopolar cortex predicted whether or not information was consciously perceived during the critical period for the attentional blink.

TL;DR: The authors conclude that the selection of targets from a rapid serial visual presentation stream is mediated by both excitatory and inhibitory attentional control mechanisms.
Abstract: The attentional blink refers to the finding that the 2nd of 2 targets embedded in a stream of rapidly presented distractors is often missed. Whereas most theories of the attentional blink focus on limited-capacity processes that occur after target selection, the present work investigates the selection process itself. Identifying a target letter caused an attentional blink for the enumeration of subsequent dot patterns, but this blink was reduced when the dots shared their color with the target letter. In contrast, performance worsened when the color of the dots matched that of the remaining distractors in the stream. Similarity between the targets also affected competition between different sets of dots presented simultaneously within a single display. The authors conclude that the selection of targets from a rapid serial visual presentation stream is mediated by both excitatory and inhibitory attentional control mechanisms.

TL;DR: Emotion-induced impairments of target awareness extended even to targets that appeared immediately before emotional distractors and when targets preceded distractors by two items—rather than by one item—negative distractors led to enhanced target processing relative to when distractors were neutral.
Abstract: When people search for targets within rapid streams of images, irrelevant emotional distractors—relative to neutral distractors—spontaneously demand attention and impair subsequent target detection, an effect that can be likened to an emotion-induced “attentional blink”. But what happens when emotional distractors appear after a target has already come and gone? Here, we describe new findings of retroactive emotion-induced effects on target awareness. First, emotion-induced impairments of target awareness extended even to targets that appeared immediately before emotional distractors (Experiment 1). Second, when targets preceded distractors by two items—rather than by one item—negative distractors led to enhanced target processing relative to when distractors were neutral (Experiment 2). In contrast, when a target appeared after an emotional distractor, target awareness was impaired regardless of whether it was the first or second subsequent item. These results potentially implicate separable impacts of e...
