一系列的四个实验测试了婴儿在流利的语言中检测重复单词的能力。在实验1中，7 1/2个月大的美国婴儿熟悉两个不同的单音节词，随后提出的段落，其中包括或不包括熟悉的目标词嵌入在句子中。婴儿听包含熟悉目标的段落的时间明显长于包含不熟悉单词的段落。一项针对6个月大婴儿的类似实验没有表明这个年龄段的婴儿在文章中发现了目标词。在实验3中，一组7 1/2个月大的孩子熟悉两个不同的非单词的目标，不同的是在他们的初始语音段只有一个或两个语音特征的话，在两个通道。这些婴儿没有表现出明显更长时间地听具有相似发音单词的段落的倾向，这表明婴儿可能将熟悉期内关于项目的相当详细的信息与测试段落中的单词相匹配。最后，实验4表明，即使7 1/2个月大的婴儿最初熟悉的目标词在连续的背景下，而不是孤立的，他们仍然表现出可靠的证据，认识这些词在测试阶段。总之，这些研究的结果表明，在流利的语音环境中检测单词的能力在7个半月大时就已经存在。(C)出版社：Academic Press
A series of four experiments examined infants' capacities to detect repeated words in fluent speech. In Experiment 1, 7 1/2-month old American infants were familiarized with two different monosyllabic words and subsequently were presented with passages which either included or did not include the familiar target words embedded in sentences. The infants listened significantly longer to the passages containing the familiar target;words than to passages containing unfamiliar words. A comparable experiment with 6-month-olds provided no indication that infants at this age detected the target words in the passages. In Experiment 3, a group of 7 1/2-month-olds was familiarized with two different non-word targets which differed in their initial phonetic segment by only one or two phonetic features from words presented in two of the passages. These infants showed no tendency to listen significantly longer to the passages with the similar sounding words, suggesting that the infants may be matching rather detailed information about the items in the familiarization period to words in the test passages. Finally, Experiment 4 demonstrated that even when the 7 1/2-month-olds were initially familiarized with target words in sentential contexts rather than in isolation, they still showed reliable evidence of recognizing these words during the test phase. Taken together, the results of these studies suggest that some ability to detect words in fluent speech contexts is present by 7 1/2 months of age. (C) 1995 Academic Press, Inc.
