Abstract
The Attentional Blink (AB) is a phenomenon where the second target stimulus (T2) cannot be detected accurately when presented shortly after the first target stimulus in a rapid serial visual presentation (RSVP) task. Kawashima et al. (2022) reported that presenting a 10 Hz auditory stimulus just before the RSVP sequence enhances the AB effect. In the present study, we analyzed neural oscillations during the AB task in open-access data in an exploratory manner to gain insight into neural oscillations that might be modulated by auditory stimulation. Our analysis revealed no significant difference in the alpha power of pre-stimulus RSVP between AB and no-AB trials. On the other hand, a difference in trial-to-trial phase coherence during the RSVP was observed between AB and no-AB trials. This result was replicated in the same participant's EEG dataset collected on a different day. Taken together, these findings suggest that the enhancement of the AB effect by a 10 Hz auditory stimulus may be due to the inhibition of phase synchrony during the RSVP stream.
