记忆和学习的研究通常集中在一个单一的感官形式，虽然人类的感知是多感官的性质。在本研究中，我们探讨了视听编码对后期单感官再认记忆绩效的影响。参与者要记住听觉或视觉刺激（声音，图片，口语或书面文字），其中每一个共同发生的语义一致的刺激，不一致的刺激，或中性（非语义噪声）刺激在编码过程中的其他方式。随后的记忆表现总体上更好的刺激时，要记住的是最初伴随着语义一致的刺激，在其他方式比当它伴随着一个中性的刺激。这些结果表明，语义一致的多感官体验增强了非语言和语言材料的编码，从而改善了他们后来的再认记忆。
Studies of memory and learning have usually focused on a single sensory modality, although human perception is multisensory in nature. In the present study, we investigated the effects of audiovisual encoding on later unisensory recognition memory performance. The participants were to memorize auditory or visual stimuli (sounds, pictures, spoken words, or written words), each of which co-occurred with either a semantically congruent stimulus, incongruent stimulus, or a neutral (non-semantic noise) stimulus in the other modality during encoding. Subsequent memory performance was overall better when the stimulus to be memorized was initially accompanied by a semantically congruent stimulus in the other modality than when it was accompanied by a neutral stimulus. These results suggest that semantically congruent multisensory experiences enhance encoding of both nonverbal and verbal materials, resulting in an improvement in their later recognition memory.
