通过在连续单词之间（重合版本）或单词内音节之间（非重合版本）的边界处插入1秒停顿来检查婴儿对流利语音中单词单位的敏感性。在实验1中，24个11个月大的孩子听巧合版本的时间明显更长。在实验2中，24名4个半月和24名9个月奥尔兹的婴儿并没有表现出11个月大的婴儿对巧合版本的偏好。在实验3中，当对刺激进行低通滤波时，24名11个月大的婴儿对巧合版本没有偏好，这表明他们依赖的不仅仅是韵律线索。实验4中的新刺激材料表明，24个11个月大的一致性和非一致性版本的反应并不完全取决于事先熟悉的目标。两组30个11个月大的孩子在实验5中测试的敏感边界强/弱字弱/强字。综上所述，结果表明，到11个月时，婴儿对流利言语中的单词边界很敏感，这种敏感性不仅仅取决于韵律信息或单词的先验知识。
Infants' sensitivity to word units in fluent speech was examined by inserting 1 sec pauses either at boundaries between successive words (Coincident versions) or between syllables within words (Noncoincident versions). In Experiment 1, 24 11-month-olds listened significantly longer to the Coincident versions. In Experiment 2, 24 four-and-a-half-and 24 nine-month-olds did not exhibit the preference for the Coincident versions that the 11-month-olds showed. When the stimuli were low-pass filtered in Experiment 3, 24 11-month-olds showed no preference for the Coincident versions, suggesting they rely on more than prosodic cues. New stimulus materials in Experiment 4 indicated that responses by 24 11-month-olds to the Coincident and Noncoindent versions did not depend solely on prior familiarity with the targets. Two groups of 30 11-month-olds tested in Experiment 5 were as sensitive to boundaries for Strong/Weak words as for Weak/Strong words. Taken together, the results suggest that, by 11 months, infants are sensitive to word boundaries in fluent speech, and that this sensitivity depends on more than just prosodic information or prior knowledge of the words.
