L. Bahrick和R. Lickliter（2000）提出了一个感觉间冗余假说，认为在两个或多个感觉模态之间以冗余和时间同步方式呈现的信息选择性地招募婴儿的注意力，并且比单一模态呈现的相同信息更有效地促进感知学习。为了支持这一观点，他们发现，5个月大的婴儿能够区分两个复杂的节奏时，他们提出了双峰，但不是单峰。本研究扩展了我们的测试的感觉间冗余假说，年幼的婴儿和不同的amodal属性。研究了3个月奥尔兹对克里思的非模态特性的敏感性。结果复制和扩展的Bahrick和Lickliter证明，婴儿可以辨别的克里思变化后双峰，但不是单峰，习惯。看来，当婴儿是第一次学习区分一个amodal刺激属性，歧视是促进间感觉冗余和衰减条件下的单峰刺激。(C)2002 Wiley Periodicals，Inc.
L. Bahrick and R. Lickliter (2000) proposed an intersensory redundancy hypothesis that states that information presented redundantly and in temporal synchrony across two or more sensory modalities selectively recruits infant attention and facilitates perceptual learning more effectively than does the same information presented unimodally. In support of this view, they found that 5-month-old infants were able to differentiate between two complex rhythms when they were presented bimodally, but not unimodally. The present study extended our test of the intersensory redundancy hypothesis to younger infants and to a different amodal property. Three-month-olds' sensitivity to the amodal property of tempo was investigated. Results replicated and extended those of Bahrick and Lickliter demonstrating that infants could discriminate a change in tempo following bimodal, but not unimodal, habituation. It appears that when infants are first learning to differentiate an amodal stimulus property, discrimination is facilitated by intersensory redundancy and attenuated under conditions of unimodal stimulation.
