This study investigated whether acoustic input, in the form of infant-directed speech, influenced infants' segmenting of action sequences. Thirty-two 7.5- to 11.5-month-old infants were familiarized with video sequences made up of short action clips. Narration coincided with portions of the action stream to package certain pairs of clips together. At test, packaged and nonpackaged pairs of actions were presented side by side in silence. Narration heard during familiarization influenced how infants viewed the action units, such that at test, infants older than 9.5 months (but not younger) looked longer at the nonpackaged than the packaged action sequences. The role of infant-directed speech as well as other types of acoustic input in assisting infants' processing of action is discussed.
本研究调查了以婴儿导向性言语形式存在的声学输入是否会影响婴儿对动作序列的分割。32名7.5至11.5个月大的婴儿观看了由短动作片段组成的视频序列。旁白与动作流的部分内容同步，将某些成对的片段组合在一起。在测试中，将组合和未组合的动作对并排无声呈现。熟悉过程中听到的旁白影响了婴儿对动作单元的看法，以至于在测试中，9.5个月以上（而非以下）的婴儿注视未组合动作序列的时间比注视组合动作序列的时间更长。本文还讨论了婴儿导向性言语以及其他类型的声学输入在帮助婴儿处理动作方面的作用。
