INTRODUCTION
Stuttering is a speech fluency disorder, and may be associated with neuroaudiological factors linked to central auditory processing, including changes in auditory processing skills and temporal resolution.
OBJECTIVE
To characterize the temporal processing and long-latency auditory evoked potential in stutterers and to compare them with non-stutterers.
METHODS
The study included 41 right-handed subjects, aged 18-46 years, divided into two groups: stutterers (n=20) and non-stutters (n=21), compared according to age, education, and sex. All subjects were submitted to the duration pattern tests, random gap detection test, and long-latency auditory evoked potential.
RESULTS
Individuals who stutter showed poorer performance on Duration Pattern and Random Gap Detection tests when compared with fluent individuals. In the long-latency auditory evoked potential, there was a difference in the latency of N2 and P3 components; stutterers had higher latency values.
CONCLUSION
Stutterers have poor performance in temporal processing and higher latency values for N2 and P3 components.
引言
口吃是一种言语流畅性障碍，可能与与中枢听觉处理相关的神经听力学因素有关，包括听觉处理技能的变化和时间分辨率。
目的
描述口吃者的时间处理和长潜伏期听觉诱发电位，并将其与非口吃者进行比较。
方法
该研究纳入了41名年龄在18至46岁之间的右利手受试者，分为两组：口吃者（n = 20）和非口吃者（n = 21），并根据年龄、教育程度和性别进行比较。所有受试者均接受持续时间模式测试、随机间隙检测测试和长潜伏期听觉诱发电位测试。
结果
与流利者相比，口吃者在持续时间模式和随机间隙检测测试中的表现较差。在长潜伏期听觉诱发电位中，N2和P3成分的潜伏期存在差异；口吃者的潜伏期值更高。
结论
口吃者在时间处理方面表现较差，N2和P3成分的潜伏期值更高。
