title: Temporal attention facilitates short-term consolidation during a rapid serial auditory presentation task.
abstract: Attentional blink (AB) refers to a phenomenon where the correct identification of a first target (i.e., target) impairs the processing of a second target (i.e., probe) nearby in time. In the present study, we investigate the influence of temporal attention on auditory AB by means of scalp-recorded event-related potentials. Participants were instructed to focus their attention on a particular time interval following the target (i.e., short, middle, or long temporal position) in order to detect the occurrence of the probe in a rapid series of distractor sounds. We found a large probe processing deficit when the probe occurred immediately after the target. This AB decreased as the time interval between the target and the probe increased and coincided with the generation of a positive wave at parietal sites (i.e., P3b). The P3b elicited by the probe peaked earlier when the probe occurred at the designated time than when it occurred at another position in time. The results indicate that temporal attention can be deployed to a particular time, which facilitates short-term consolidation of the probe.
