TL;DR: It is demonstrated that manipulating the pre-stimulus condition can reduce deficits in temporal attention characterizing the human cognitive architecture, suggesting innovative trainings for acquired and neurodevelopmental disorders.
Abstract: Our ability to allocate attention at different moments in time can sometimes fail to select stimuli occurring in close succession, preventing visual information from reaching awareness. This so-called attentional blink (AB) occurs when the second of two targets (T2) is presented closely after the first (T1) in a rapid serial visual presentation (RSVP). We hypothesized that entrainment to a rhythmic stream of stimuli—before visual targets appear—would reduce the AB. Experiment 1 tested the effect of auditory entrainment by presenting sounds with a regular or irregular interstimulus interval prior to a RSVP where T1 and T2 were separated by three possible lags (1, 3 and 8). Experiment 2 examined visual entrainment by presenting visual stimuli in place of auditory stimuli. Results revealed that irrespective of sensory modality, arrhythmic stimuli preceding the RSVP triggered an alerting effect that improved the T2 identification at lag 1, but impaired the recovery from the AB at lag 8. Importantly, only auditory rhythmic entrainment was effective in reducing the AB at lag 3. Our findings demonstrate that manipulating the pre-stimulus condition can reduce deficits in temporal attention characterizing the human cognitive architecture, suggesting innovative trainings for acquired and neurodevelopmental disorders.

TL;DR: In this article, the index and middle fingers of the right and left hands were stimulated by a triplet of tactile presses, each of which was composed of a brief press to one finger (e.g., the middle finger), followed by a brief pressing to the other finger, and by a final simultaneous pressing to both fingers of a given hand.
Abstract: Brief tactile presses stimulated the index and middle fingers of the right and left hands. The stimulation on each hand consisted of a triplet of presses. Each triplet was composed of a brief press to one finger (e.g., the middle finger), followed by a brief press to the other finger (e.g., the index finger), and by a final simultaneous press to both fingers of a given hand. With equal probability, a triplet could begin with the index or middle finger, and either 360 ms or 800 ms later another triplet stimulated fingers on the other hand. The task was to indicate which finger was stimulated first in each triplet. In four experiments, response accuracy to the second triplet revealed an attentional blink in taction, that is, responses were less accurate at the short triplet–triplet interval than at the long triplet–triplet interval. This effect was substantially reduced when the first triplet could be ignored.

TL;DR: Examination of the attentional blink in abstinent opiate dependent patients found that there was an exaggerated attentional blinking, suggesting that there were the deficits of information processing and attention in AODPs.
Abstract: The attentional blink reveals the limits of the brain's ability in information processing. It has been extensively studied in people with neurological and psychiatric disturbances to explore the temporal characteristics of information processing and examine attention deficits. The aim of the present study is to examine the attentional blink in abstinent opiate dependent patients (AODPs). Also, we planned to study whether addiction-associated and affective stimuli can influence the attentional blink in AODPs. A dual-target rapid serial visual presentation test (RSVP) was used in the present study. The second target consisted of three kinds of stimuli: neutral, addiction-associated and negative. We found that there was an exaggerated attentional blink in AODPs. It suggested that there were the deficits of information processing and attention in AODPs. Addiction-associated stimuli reduced the attentional blink in AODPs, suggesting addiction-associated information were selected by the brain for attentive and perceptual processing. In addition, affective effects on the attentional blink in AODPs were not in the similar level to those in controls.

TL;DR: Differences in pre-target electrophysiology between correctly and incorrectly reported trials are examined, considering amplitude and phase measures of alpha oscillations as well as the steady-state visual evoked potential (ssVEP) evoked by the RSVP stream to suggest a dynamic brain state that predicts lower accuracy in terms of reporting the second target under strict temporal constraints.
Abstract: Reporting the second of two targets within a stream of distracting words during rapid serial visual presentation (RSVP) is impaired when the targets are separated by a single distractor word, a deficit in temporal attention that has been referred to as the attentional blink (AB) Recent conceptual and empirical work has pointed to pre-target brain states as potential mediators of the AB effect The current study examined differences in pre-target electrophysiology between correctly and incorrectly reported trials, considering amplitude and phase measures of alpha oscillations as well as the steady-state visual evoked potential (ssVEP) evoked by the RSVP stream For incorrectly reported trials, relatively lower alpha-band power and greater ssVEP inter-trial phase locking were observed during extended time periods preceding presentation of the first target These results suggest that facilitated processing of the pre-target distracter stream indexed by reduced alpha and heightened phase locking characterizes a dynamic brain state that predicts lower accuracy in terms of reporting the second target under strict temporal constraints Findings align with hypotheses in which the AB effect is attributed to neurocognitive factors such as fluctuations in pre-target attention or to cognitive strategies applied at the trial level
