口吃的成年人（AWS）经常尝试抑制他们的口吃，并取得不同程度的成功。启动后有效抑制运动行为的能力依赖于执行功能，如非选择性抑制。虽然以前的研究发现，AWS比不口吃的成年人（AWNS）更慢地抑制手动按钮按压反应，但研究尚未证实手动和口头抑制之间的一致关系。没有研究检查AWS的言语抑制能力。本研究的目的，因此，是比较AWS和AWNS之间的言语反应抑制，并比较言语反应抑制的公开口吃和口吃的生活experience of stuttering.MethodThirty-four成年人（17 AWNS，17 AWS）完成了一个手动和三个口头停止信号的任务。AWS进行了评估口吃的严重程度（口吃严重程度仪器，第四版：SSI-4）和经验与口吃（整体评估的扬声器的经验与口吃[OASES]）。ResultsResults表明手动和口头抑制两组之间没有相关性。广义线性混合模型分析表明，在手动或口头抑制没有显着的组间差异。手动和口头抑制没有预测SSI-4在AWS。然而，言语抑制是唯一与OASES scores.ConclusionAlthough潜在的手动和言语抑制是AWS和AWNS之间的可比性，言语抑制可能与口吃的不良经历，而不是口吃严重程度的明显症状。补充材料https：doi.org/10.23641/asha.15145185
PurposeAdults who stutter (AWS) often attempt, with varying degrees of success, to suppress their stuttered speech. The ability to effectively suppress motoric behavior after initiation relies on executive functions such as nonselective inhibition. Although previous studies found that AWS were slower to inhibit manual, button-press response than adults who do not stutter (AWNS), research has yet to confirm a consistent relationship between manual and verbal inhibition. No study has examined verbal inhibition ability in AWS. The purpose of this study, therefore, is to compare verbal response inhibition between AWS and AWNS, and compare verbal response inhibition to both the overt stuttering and the lived experience of stuttering.MethodThirty-four adults (17 AWNS, 17 AWS) completed one manual and three verbal stop-signal tasks. AWS were assessed for stuttering severity (Stuttering Severity Instrument–Fourth Edition: SSI-4) and experience with stuttering (Overall Assessment of the Speaker's Experience With Stuttering [OASES]).ResultsResults indicate no correlation between manual and verbal inhibition for either group. Generalized linear mixed-model analyses suggested no significant group differences in manual or verbal inhibition. Manual and verbal inhibition did not predict SSI-4 in AWS. However, verbal inhibition was uniquely associated with OASES scores.ConclusionAlthough underlying manual and verbal inhibition was comparable between AWS and AWNS, verbal inhibition may be linked to the adverse experience of stuttering rather than the overt symptoms of stuttering severity.Supplemental Materialhttps://doi.org/10.23641/asha.15145185
