The purpose of the present investigation was to assess longitudinal word- and sentence-level measures of stuttering in young children. Participants included 12 stuttering and non-stuttering children between 36 and 71 months of age at an initial visit who exhibited a range of stuttering rates. Parent-child spontaneous speech samples were obtained over a period of two years at six-month intervals. Each speech sample was transcribed, and both stuttering-like disfluencies (SLDs) and other disfluencies (ODs) were coded. Word- and sentence-level measures of SLDs were used to assess linguistic characteristics of stuttering. Results of the word-level analysis indicated that stuttering was most likely to occur at the sentence-initial position, and that a tendency to stutter on function words was present only at the sentence-initial position. Results of the sentence-level analyses indicated that sentences containing ODs and those containing SLDs were both significantly longer and more complex than fluent sentences, but did not differ from each other. Word- and sentence-level measures also did not change across visits. Results were taken to suggest that both SLDs and ODs originate during the same stage of sentence planning.
The reader will be able to: (1) describe the importance of sentence position in the occurrence of speech disfluencies, (2) describe the relation between sentence complexity and the occurrence of speech disfluencies, and (3) describe the potential role of different aspects of sentence planning on the occurrence of speech disfluencies.
本研究旨在评估儿童口吃的纵向单词和句子层面的测量。参与者包括 12 名口吃和非口吃儿童,他们在初次就诊时年龄在 36 至 71 个月之间,表现出不同的口吃率。在两年的时间里,每隔六个月采集一次父母与孩子的自然语言样本。每个语音样本都被转录,并且口吃样不流畅(SLD)和其他不流畅(OD)都被编码。使用 SLD 的单词和句子层面的测量来评估口吃的语言特征。单词层面分析的结果表明,口吃最有可能发生在句子的初始位置,并且在句子初始位置上只存在倾向于使用功能词的口吃。句子层面分析的结果表明,包含 ODs 和包含 SLD 的句子都比流利的句子长且复杂,但彼此之间没有差异。单词和句子层面的测量也没有随时间而变化。结果表明,SLD 和 ODs 都起源于句子规划的同一阶段。
读者将能够:(1)描述句子位置对口吃发生的重要性,(2)描述句子复杂度与言语不流畅发生的关系,以及(3)描述句子规划不同方面对口吃发生的潜在作用。
