In the present study we investigate the role of attention in audiovisual semantic interference, by using an attentional blink paradigm. Participants were asked to make an unspeeded response to the identity of a visual target letter. This target letter was preceded at various SOAs by a synchronized audiovisual letter-pair, which was either congruent (e.g. hearing an "F" and viewing an "F") or incongruent (e.g. hearing an "F" and viewing a "Z"). In Experiment 1, participants were asked to match the members of the audiovisual letter-pair. In Experiment 2, participants were asked to ignore the synchronized audiovisual letter-pairs altogether and only report the visual target. In Experiment 3, participants were asked to identify only one of the audiovisual letters (identify the auditory letter, and ignore the synchronized visual letter, or vice versa). An attentional blink was found in all three experiments indicating that the audiovisual letter-pairs were processed. However, a congruency effect on subsequent target detection was observed in Experiments 1 and 3, but not in Experiment 2. The results indicate that attention to the semantic contents of at least one modality is necessary to establish audiovisual semantic interference.
在本研究中，我们通过使用注意瞬脱范式来探究注意在视听语义干扰中的作用。要求参与者对视觉目标字母的身份做出非快速反应。在不同的刺激呈现间隔（SOA）下，这个目标字母之前会出现一个同步的视听字母对，该字母对要么是一致的（例如听到“F”并看到“F”），要么是不一致的（例如听到“F”并看到“Z”）。在实验1中，要求参与者匹配视听字母对的成员。在实验2中，要求参与者完全忽略同步的视听字母对，只报告视觉目标。在实验3中，要求参与者只识别其中一个视听字母（识别听觉字母并忽略同步的视觉字母，反之亦然）。在所有三个实验中都发现了注意瞬脱，这表明视听字母对得到了加工。然而，在实验1和实验3中观察到了对后续目标检测的一致性效应，而在实验2中没有。结果表明，要建立视听语义干扰，至少对一种模态的语义内容予以注意是必要的。
