ABSTRACT

Multisensory experiences crucially contribute to the development of infants’ ability to match audio-visual (A-V) information. This study investigated two-day-old newborns’ ability to bind non-verbal, naturally occurring, experienced A-V stimuli. Our results demonstrate that, when presented with experienced stimuli (yawns and hiccups) within an intermodal matching procedure, 2-days-old newborns matched not only synchronous (Experiment 1) but also asynchronous A-V information (Experiment 2). Conversely, no evidence of A-V association was found when unexperienced stimuli, such as a linguistic sound (syllable/ba/) (Experiment 3), were presented in asynchrony. The possible role of sensorimotor experience in the early emergence of intersensory abilities is discussed.

摘要

多感官体验对发展婴儿匹配视听 (AV) 信息的能力至关重要。这项研究调查了两天大的新生儿结合非语言、自然发生的、经历过的 AV 刺激的能力。我们的研究结果表明，当在多式联运匹配过程中出现有经验的刺激（打哈欠和打嗝）时，2 天大的新生儿不仅匹配同步（实验 1）而且匹配异步 AV 信息（实验 2）。相反，当以异步方式呈现诸如语言声音（音节/ba/）（实验 3）之类的未体验刺激时，没有发现 AV 关联的证据。讨论了感觉运动体验在感觉间能力早期出现中的可能作用。
