The present study investigated segmentation and rhyme abilities, skills critical for phonological encoding, of children who stutter (CWS) and those who do not (CNS). Participants were 9 CWS (8 males and 1 female, mean age=11.1, SD=2.31) in the age range of 7 and 13 years and 9 age and sex matched CNS (mean age=11.2, SD=2.19). Participants performed two verbal monitoring tasks, phoneme and rhyme monitoring, in silent naming. Performances in the verbal monitoring tasks were compared to a neutral, nonverbal tone monitoring task. Additionally, the complexity of the phoneme monitoring task was varied such that participants had to monitor for singletons vs. consonant clusters. Repeated measures analysis of the response time data did not reveal significant differences between the groups in the three monitoring tasks. Analysis of the complexity data revealed a trend for slower monitoring of the consonant clusters in the CWS group compared to the CNS. Present findings do not support a deficit in segmentation and rhyme abilities in CWS, although there was some preliminary evidence of segmentation difficulties with increasing phonological complexity of the stimuli.
At the end of this activity the reader will be able to: (a) discuss the literature on phonological encoding skills in children who stutter, (b) describe skills underlying the phonological encoding process, (c) summarize whether or not children who stutter differ from those who do not in segmentation and rhyme abilities, (d) suggest future areas of research in the investigation of segmentation and rhyme monitoring abilities in children who stutter.
本研究调查了口吃儿童(CWS)和非口吃儿童(CNS)的分段和押韵能力,这些能力是语音编码的关键技能。参与者包括 9 名口吃儿童(8 名男性和 1 名女性,平均年龄=11.1,标准差=2.31),年龄在 7 至 13 岁之间,以及 9 名年龄和性别匹配的非口吃儿童(平均年龄=11.2,标准差=2.19)。参与者在静默命名中进行了两项口头监测任务,即音位和押韵监测。将口头监测任务的表现与中性、非言语音调监测任务进行了比较。此外,还改变了音位监测任务的复杂性,使参与者必须监测单音节与辅音群。对反应时间数据的重复测量分析并未显示出两组在三个监测任务中的显著差异。对复杂性数据的分析表明,与 CNS 相比,CWS 组在监测辅音群时的速度较慢,这只是一个趋势。目前的研究结果并不支持 CWS 在分段和押韵能力方面存在缺陷,尽管有一些初步证据表明,随着刺激的语音复杂性增加,存在分段困难。
在本活动结束时,读者将能够:(a)讨论关于口吃儿童语音编码技能的文献,(b)描述语音编码过程中的技能,(c)总结口吃儿童与非口吃儿童在分段和押韵能力方面是否存在差异,(d)提出未来研究口吃儿童分段和押韵监测能力的领域。
