信息丰富的多模态环境的成功导航涉及听觉和视觉信息的处理。由于许多因素，每个模态内的信息被处理的程度不同，但是在这些多模态环境中听觉刺激对视觉刺激处理的影响还没有很好地理解。先前的研究表明，在视觉任务中，前面的声音会导致反应时间减少。目前的研究探讨，如果一个非空间的，任务无关的声音，另外改变了中央目标侧面的视觉干扰处理。我们使用了一个侧翼任务的版本，其中参与者对两个不相关的侧翼字母包围的中心字母做出反应。当这些侧翼与冲突反应相关联时，就会发生一致性效应，从而减缓对目标的反应时间。在两个实验中使用这个任务，结果表明，前面的音调引起一般的反应时间加快跨侧翼类型，与警报一致。音调也会导致反应时间的变化减少。关键的是，语气调制的一致性效果，与更大的速度一致的侧翼比不一致的侧翼。这表明，侧翼身份的影响更强烈的音调呈现后，与非空间的声音增加感知和/或响应关联处理侧翼刺激一致。
Successful navigation of information-rich, multimodal environments involves processing of both auditory and visual information. The extent to which information within each modality is processed varies due to many factors, but the influence of auditory stimuli on the processing of visual stimuli in these multimodal environments is not well understood. Previous research has shown that a preceding sound leads to decreased reaction times in visual tasks. The current study examines if a non-spatial, task-irrelevant sound additionally alters processing of visual distractors that flank a central target. We utilized a version of a flanker task in which participants responded to a central letter surrounded by two irrelevant flanker letters. When these flankers are associated with a conflicting response, a congruency effect occurs such that reaction time to the target is slowed. In two experiments using this task, results showed that a preceding tone caused general speeding of reaction time across flanker types, consistent with alerting. The tone also caused decreased variation in response time. Critically, the tone modulated the congruency effect, with a greater speeding for congruent flankers than for incongruent flankers. This suggests that the influence of flanker identity was more intense after tone presentation, consistent with a nonspatial sound increasing perceptual and/or response-association processing of flanking stimuli.
