This study attempted to confirm the theory that central auditory processing deficits exist in the normally disfluent population. Forty adults, 20 males, and 20 females were administered the Synthetic Sentence Identification-Ipsilateral Competing Message (SSI-ICM) at -20 dB message-to-competition ratios. Results revealed a significant difference between the performance of fluent and disfluent normal speakers. No significant differences were found between ears or between male and female subjects. Discussion includes comparative data analyses with a previous study and implications for further research.
本研究试图证实这样一种理论，即正常口吃人群存在中枢听觉处理缺陷。40名成年人，20名男性和20名女性在消息与竞争比为-20分贝的条件下接受了合成句子识别-同侧竞争消息（SSI-ICM）测试。结果显示，流利型和口吃型正常说话者的表现存在显著差异。在双耳之间或男女受试者之间未发现显著差异。讨论包括与先前一项研究的比较数据分析以及对进一步研究的启示。
