TL;DR: Three separable P3 components, corresponding to the three targets, were obtained when lag-2 sparing occurred, suggesting that each target can be consolidated independently.
Abstract: When observers are asked to identify two targets (T1 and T2) embedded in a rapid serial visual presentation, they frequently fail to identify T2 if it appears 200–500 ms after T1 (attentional blink). The response to T2 is, however, unimpaired if it appears directly after T1 (lag-1 sparing). Furtherm

TL;DR: In this article, the authors examined the effect of the attentional blink on the ability to shift spatial attention when two targets are presented in rapid succession at the same spatial location and found significant cueing effects on T2 response times that were strongly modulated by the AB.
Abstract: When two targets are presented in rapid succession at the same spatial location, processing of the first is highly efficient, while processing of the second is often profoundly impaired at brief inter-target intervals (attentional blink; AB). While the AB has been shown to impact many processes, it is still unclear whether this includes the ability to shift spatial attention. The present study examined this question using a more sensitive dependent measure than past studies; namely, response times. It also evaluated whether masking of the cue stimulus modulated the effect of the AB on spatial shifts. The results showed significant cueing effects on T2 response times that were strongly modulated by the AB. This supports suggested links between mechanisms underlying object processing and spatial shifts of attention.

TL;DR: The underlying causes of masking the target in the attentional blink paradigm increased the magnitude of the AB relative to when the first target is not masked and significantly reduced the amplitude of the target-locked P3 but had no effect on P3 latency.
Abstract: Masking of the first target in the attentional blink (AB) paradigm increases the magnitude of the AB relative to when the first target is not masked. We examined the underlying causes of this effect in an experiment in which a single target was presented in a rapid visual serial presentation stream. The P3 to the target was isolated by subtracting infrequent target category trials from frequent target category trials. The item immediately trailing the target (i.e., the mask) was present in the masked condition and replaced by a blank screen in the not-masked condition, reproducing conditions known to modulate the AB. Masking the target significantly reduced the amplitude of the target-locked P3 but had no effect on P3 latency. Results are discussed in relation to previous findings in the AB literature.

TL;DR: It is found that patients all manifested impaired performance compared to healthy controls and that reward modulated the pathological blink in the patient group, but only in the second experimental session, which has implications for the understanding of motivation-attention interactions following right hemisphere stroke.

TL;DR: Both sex and emotional expression of the T1 stimulus were found to independently affect reporting of T2, suggesting that both emotional expression and stimulus sex are important in the temporal allocation of attentional resources to faces.
Abstract: Past studies have demonstrated that angry faces used as the first target (T1) in an attentional blink paradigm interfere with processing of a second, neutral target (T2). However, despite research that suggests that the sex and emotional expression of a face are confounded, no study has investigated whether the sex of a stimulus might interact with emotional expression to influence the attentional blink. In the current study, both the sex and emotional expression of a T1 stimulus were manipulated to assess participants' ability to report the presences of a subsequent neutral target. Although the findings revealed limited evidence to support an interaction between sex and emotion, both the sex and emotional expression of the T1 stimulus were found to independently affect reporting of T2. These findings suggest that both emotional expression and stimulus sex are important in the temporal allocation of attentional resources to faces.
