虽然人类在日常生活中几乎不断地受到来自多种感官形式的刺激，但我们学习整合来自多种感官的信息以获得多感官对象知识的过程并不清楚。在这里，我们提出了一种新的视听统计学习过程的结果，参与者被动地暴露于任意视听配对（包括人工/合成的音频和视觉刺激）的快速串行演示。在此曝光后，参与者进行了测试，两个间隔的强制选择程序，其中他们的熟悉程度与经验丰富的视听配对进行了评估，对新的视听组合来自相同的刺激集。我们的研究结果表明，受试者获得知识的视觉，视听，视听刺激协会和这些类型的协会的学习发生在一个独立的方式。
Although humans are almost constantly exposed to stimuli from multiple sensory modalities during daily life, the processes by which we learn to integrate information from multiple senses to acquire knowledge of multisensory objects are not well understood. Here, we present results of a novel audio-visual statistical learning procedure where participants are passively exposed to a rapid serial presentation of arbitrary audio-visual pairings (comprised of artificial/ synthetic audio and visual stimuli). Following this exposure, participants were tested with a two-interval forced-choice procedure in which their degree of familiarity with the experienced audio-visual pairings was evaluated against novel audio-visual combinations drawn from the same stimulus set. Our results show that subjects acquire knowledge of visual-visual, audio-audio, and audio-visual stimulus associations and that the learning of these types of associations occurs in an independent manner.
