目的：本研究的目的是探讨（a）口吃儿童（CWS）和非口吃儿童（CWNS）的外显和内隐言语反应抑制以及（B）反应抑制与语言技能的关系。外显言语反应抑制使用计算机化版本的草雪任务（卡尔森和摩西，2001年），内隐言语反应抑制使用咩喵任务。结果：CWS在内隐任务上的准确性显著低于CWNS，而在外显任务上的准确性无显著差异。在这两项任务中，CWS的反应时间也比CWNS慢。组间表现的差异不能归因于工作记忆的需求。总体而言，儿童的抑制任务上的表现与父母的看法，他们的孩子的抑制技能在日常living.Conclusions：CWS是不太有效和高效的比CWNS在抑制一个占主导地位的反应，而执行一个冲突的反应在口头域。
Purpose: The purpose of this study was to examine (a) explicit and implicit verbal response inhibition in preschool children who do stutter (CWS) and do not stutter (CWNS) and (b) the relationship between response inhibition and language skills.Method: Participants were 41 CWS and 41 CWNS between the ages of 3; 1 and 6; 1 (years; months). Explicit verbal response inhibition was measured using a computerized version of the grass-snow task (Carlson & Moses, 2001), and implicit verbal response inhibition was measured using the baa-meow task. Main dependent variables were reaction time and accuracy.Results: The CWS were significantly less accurate than the CWNS on the implicit task, but not the explicit task. The CWS also exhibited slower reaction times than the CWNS on both tasks. Between-group differences in performance could not be attributed to working memory demands. Overall, children's performance on the inhibition tasks corresponded with parents' perceptions of their children's inhibition skills in daily life.Conclusions: CWS are less effective and efficient than CWNS in suppressing a dominant response while executing a conflicting response in the verbal domain.
