背景资料：流利的演讲者和口吃的人表现出自主神经和情绪反应的变化，因为他们认为口吃相对于流利的语音样本。这些反应表明了一种被唤醒的自主神经状态，并被假设为是由口吃中流利性的突然中断所触发的。此外，这些反应被认为是不同的交际伙伴对口吃者的刻板印象的基础。目的：研究言语语言病理学临床研究生在观察流利和严重口吃言语样本时的自主神经和情绪反应。方法和程序：21名女性研究生临床言语语言病理学参与了这项研究。每个参与者观看了四个30秒的视频样本（两个流利的和两个口吃的语音样本），同时捕获他们的自主反应（皮肤电导反应（SCR）和心率（HR））。此外，口吃和流利的语音样本的情绪反应被捕获使用的自我评估假人（SAM）和评级量表与9个双极形容词反映一个人的感情。成果与结果：研究生临床医生观察口吃语音样本与流利语音样本时，观察到SCR增加和HR减速，差异具有统计学意义。此外，自评量表的结果显示，参与者有消极的感觉（例如，情绪激动的，不愉快的，尴尬的，不舒服的，等等）同时观看口吃的演讲。结论和影响：研究结果表明，研究生临床医生在言语语言病理学表现出改变自主神经和情感反应类似的表现流利和口吃的扬声器，因为他们看到口吃的语音样本。总的来说，这些发现支持了这样一种观点，即口吃的固有性质会引发听众的本能反应，而不管他们的背景和对这种疾病的了解如何。
Background: Fluent speakers and people who stutter manifest alterations in autonomic and emotional responses as they view stuttered relative to fluent speech samples. These reactions are indicative of an aroused autonomic state and are hypothesized to be triggered by the abrupt breakdown in fluency exemplified in stuttered speech. Furthermore, these reactions are assumed to be the basis for the stereotypes held by different communicative partners towards people who stutter. Aims: To examine the autonomic and emotional reactions of graduate student clinicians in speechlanguage pathology as they viewed fluent and severe stuttered speech samples. Methods & Procedures: Twenty-one female graduate student clinicians in speechlanguage pathology participated in this study. Each participant viewed four 30-s video samples (two fluent and two stuttered speech samples) while their autonomic responses (skin conductance response (SCR) and heart rate (HR)) were concurrently captured. Furthermore, emotional responses to stuttered and fluent speech samples were captured using the self-assessment manikin (SAM) and a rating scale with nine bipolar adjectives reflecting one's feelings. Outcomes & Results: An increase in SCR and deceleration in HR was observed as graduate clinicians viewed stuttered speech samples versus fluent speech samples and the differences were statistically significant. In addition, results from the self-rating scales showed that participants had negative feelings (e.g., emotionally aroused, unpleasant, embarrassed, uncomfortable, etc.) while viewing stuttered speech. Conclusions & Implications: Findings suggest that graduate student clinicians in speechlanguage pathology demonstrated altered autonomic and emotional responses similar to those manifested by fluent and stuttered speakers as they viewed stuttered speech samples. Collectively, these findings support the contention that the inherent nature of stuttered speech triggers a visceral reaction in a listener, irrespective of their background and knowledge about the disorder.
