“…The reduced P3b wave elicited by the probe during the AB can perhaps be explained by the possibility that the processing of some probes does not reach the consolidation stage because they are overwritten or passively decay during the time the participant is waiting for the completion of target processing. Accordingly, this waiting results in the delay of P3b waves [12], [21], [25], [34]. From this perspective, the increase in accuracy and P3b amplitude during the AB would indicate that the probe reached the capacity-limited short-term consolidation more often when attention was implicitly allocated at the expected time as predicted by the probe probability.…”

Attentional blink (AB) describes a phenomenon whereby correct identification of a first target impairs the processing of a second target (i.e., probe) nearby in time. Evidence suggests that explicit attention orienting in the time domain can attenuate the AB. Here, we used scalp-recorded, event-related potentials to examine whether auditory AB is also sensitive to implicit temporal attention orienting. Expectations were set up implicitly by varying the probability (i.e., 80% or 20%) that the probe would occur at the +2 or +8 position following target presentation. Participants showed a significant AB, which was reduced with the increased probe probability at the +2 position. The probe probability effect was paralleled by an increase in P3b amplitude elicited by the probe. The results suggest that implicit temporal attention orienting can facilitate short-term consolidation of the probe and attenuate auditory AB.

“…The P3b wave recorded during visual and auditory AB has been proposed as an index of processes engaged during the short-term consolidation stage [25], [26]. Because short-term consolidation is capacity-limited, the target and the probe could not be processed at the same time.…”

“…There is evidence that auditory AB, like visual AB, can also be modulated by attention orienting in a rapid serial auditory presentation task (Shen and Alain, 2011). Temporal attention was manipulated by task instruction and was blocked for an entire recording session to emphasize focused attention at the designated temporal position.…”

Auditory perception and cognition entails both low-level and high-level processes, which are likely to interact with each other to create our rich conscious experience of soundscapes. Recent research that we review has revealed numerous influences of high-level factors, such as attention, intention, and prior experience, on conscious auditory perception. And recently, studies have shown that auditory scene analysis tasks can exhibit multistability in a manner very similar to ambiguous visual stimuli, presenting a unique opportunity to study neural correlates of auditory awareness and the extent to which mechanisms of perception are shared across sensory modalities. Research has also led to a growing number of techniques through which auditory perception can be manipulated and even completely suppressed. Such findings have important consequences for our understanding of the mechanisms of perception and also should allow scientists to precisely distinguish the influences of different higher-level influences.

“…In most studies investigating the effect of aging on distraction and its electrophysiological 22 correlates, involuntary attention switching was induced by rare (oddball) stimuli which broke the 23 regularity of a sequence comprising frequent stimuli. Distraction was characterized by rare-24 minus-frequent (behavioral or ERP) response differences.…”
