In the rapid serial visual presentation (RSVP) paradigm, response accuracy for the target decreases when it appears within a short time window (200~500 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.
在快速序列视觉呈现 (RSVP) 范式中，当目标在前一个目标之后的短时间窗口 (200~500ms) 内出现时，对目标的反应准确性会降低。这种现象被称为注意瞬脱 (AB)。尽管已经记录了减少 AB 的跨模态处理机制，但研究人员尚未探索模态注意条件下的差异。在本研究中，我们使用 RSVP 范式在特定模态选择性注意（实验 1）和双模态分散注意（实验 2）下研究听觉驱动的视觉目标感知增强对 AB 的影响。结果表明，跨模态注意增强不受刺激显著性的调节。此外，结果还表明，当注意的声音与目标同时出现时，准确性更高。这些结果表明，视听增强降低了 AB，并且在双模态分散注意条件下更强的注意增强导致 AB 的消失。
