The frequency of reduplication was examined in relation to syllable maintenance, final consonant production, and whole word repetitions in two preschool children with specific language impairment--one who reduplicated frequently and one who did so infrequently. Spontaneous speech was sampled for a period of 18 months. During the single-word utterance period, reduplication was associated with infrequent production of final consonants but frequent maintenance of multisyllabic structure. After the single-word utterance period the child who had frequently reduplicated during this period ceased reduplication but frequently produced whole word repetitions. Infrequent production of final consonants continued, but syllable maintenance decreased. The data are discussed in relation to hypotheses about the function of reduplication and the function of whole word repetitions in language development.
研究了两名患有特定语言障碍的学龄前儿童的重复频率，该频率与音节保持、词尾辅音发音以及单词整体重复情况相关——其中一名儿童频繁重复，另一名则很少重复。对18个月期间的自发言语进行了采样。在单词单音节发音阶段，重复与词尾辅音的不频繁发音以及多音节结构的频繁保持有关。在单词单音节发音阶段之后，在此期间频繁重复的儿童停止了重复，但频繁出现单词整体重复。词尾辅音的不频繁发音仍在继续，但音节保持能力下降。结合关于重复功能和单词整体重复在语言发展中的功能的假设对这些数据进行了讨论。
