目的：本研究的主要目的是考察4-5岁口吃儿童语音意识的发展与最终恢复(CWS-EREC)或持续(CWS-ePer)的关系，以解释典型言语(TS)产生或言语声音障碍(SSD)的存在。方法：在为期5年的纵向研究的第一年，37名非口吃儿童(CWNS)和48名CWS完成了语音意识测验第二版(Robertson&Salter，2007)的韵母辨别和韵律产生任务。根据他们参与的最后一年的数据，CWS被分为CWS-ePer和CWS-EREC。每个CWS组根据押韵任务时的语音产生能力被进一步分为TS组和SSD组。对押韵任务的准确性进行了比较。结果：在押韵辨别任务中，各组的押韵辨别任务表现相似。在押韵任务上，CWS-ePer-SSD和CWS-EREC-SSD的准确率低于CWNS，但CWS-ePer-TS、CWS-EREC-TS和CWNS的准确率相近。在正确的押韵实验中，CWS-ePer-TS产生的非单词押韵比真实单词押韵更多。CWS-ePer-TS使用非词语策略的比率是CWNS的1.88倍。CWS-EREC-TS在非词策略的使用上介于CWS-ePer-TS和CWNS之间。结论：CWS-ePer-TS对非词策略的依赖可能反映了CWS-ePer-TS在潜在语音表征上的差异，以及与CWNS相比更容易获得词汇。
Purpose: The primary aim of the current study was to examine the developing phonological awareness of 4- to 5-year-old children who stutter (CWS) in relation to eventual recovery (CWS-eRec) or persistance (CWS-ePer) in stuttering, accounting for the presence of typical speech (TS) production or speech sound disorder (SSD).Method: In the 1st year of a 5-year longitudinal study, 37 children who do not stutter (CWNS) and 48 CWS completed a rhyme discrimination and a rhyme production task from the Phonological Awareness Test-Second Edition (Robertson & Salter, 2007). Using data from their last year of participation, CWS were classified into CWS-ePer and CWS-eRec. Each CWS group was further divided into TS and SSD groups based on speech production abilities at the time of the rhyme tasks. Accuracy on the rhyme tasks was compared. Groups were also compared on strategies used to generate correct and incorrect responses for the rhyme production task (e.g., real-word correct, nonword correct, semantic association, repeated cues).Results: All groups performed similarly on the rhyme discrimination task. On the rhyme production task, CWS-ePer-SSD and CWS-eRec-SSD performed with less accuracy than CWNS, but CWS-ePer-TS, CWS-eRec-TS, and CWNS achieved similar task accuracy. On correct rhyme production trials, CWS-ePer-TS created more nonword rhymes than real-word rhymes. CWS-ePer-TS used the nonword strategy at 1.88 times the CWNS rate. CWS-eRec-TS fell between CWS-ePer-TS and CWNS in use of the nonword strategy.Conclusions: Reliance on a nonword strategy for rhyme production in CWS-ePer-TS may reflect differences in underlying phonological representations and ease of phonological access to the lexicon compared to CWNS.
