Modal-based attention modulates attentional blink

In the rapid serial visual presentation (RSVP) paradigm, response accuracy for the target decreases when it appears within a short time window (200 similar to 500 ms) after the previous target. This phenomenon is termed the attentional blink (AB). Although mechanisms of cross-modal processing that reduce the AB have been documented, researchers have not explored the differences across modal attentional conditions. In the present study, we used the RSVP paradigm to investigate the effect of auditory-driven visual target perceptual enhancement on the AB under modality-specific selective attention (Experiment 1) and bimodal-divided attention (Experiment 2). The results showed that cross-modal attentional enhancement was not moderated by stimulus salience. Moreover, the results also showed that accuracy was higher when the attended sound appeared simultaneously with the target. These results indicated that audiovisual enhancement reduced AB and that stronger attentional enhancement in the bimodal-divided attentional condition led to the disappearance of AB.

Automated summary

The study investigated the impact of auditory-driven visual target perceptual enhancement on attentional blink (AB) using the RSVP paradigm. The results showed that cross-modal attentional enhancement was not influenced by stimulus salience, and stronger attentional enhancement in the bimodal condition led to the disappearance of AB.
