知觉学习的研究主要集中在单感觉刺激上。然而，多感官交互在感知中无处不在，甚至在早期处理阶段也是如此，因此可能在学习中发挥作用。在这里，我们研究听觉视觉一致性对视觉学习的影响。受试者接受了为期五天的视觉运动一致性检测任务的训练，其中包括一致的视听或不一致的视听刺激。比较仅视觉试验的表现，我们发现使用一致的视听刺激进行训练比使用不一致的视听刺激或仅使用视觉刺激进行训练产生明显更好的学习效果。训练过程中刺激一致性的优势表明，多感官训练的好处可能来自于感知层面而非认知层面的视听互动。
Studies of perceptual learning have largely focused on unisensory stimuli. However, multisensory interactions are ubiquitous in perception, even at early processing stages, and thus can potentially play a role in learning. Here, we examine the effect of auditory-visual congruency on visual learning. Subjects were trained over five days on a visual motion coherence detection task with either congruent audiovisual, or incongruent audiovisual stimuli. Comparing performance on visual-only trials, we find that training with congruent audiovisual stimuli produces significantly better learning than training with incongruent audiovisual stimuli or with only visual stimuli. This advantage from stimulus congruency during training suggests that the benefits of multisensory training may result from audiovisual interactions at a perceptual rather than cognitive level.
