Abstract

We present a single-case study on the potential clinical relevance of a new altered auditory feedback (AAF) device (Forbrain^®) in stuttering. One adult who stutter was tested in an appropriately-controlled single-case time-series (A-B-A) study. On each of six consecutive working days, the stuttering adult was instructed to read aloud during three different experimental phases: Baseline, Test and Post-test, while wearing a Forbrain^® headset. During the Test phase the device was turned on, whereas it was off during Baseline and Post-test phases. This way the transient effects of Forbrain^® could be analyzed. Six quantitative measures of voice quality were retrieved from the participant's voice recordings during his readings over each phase of the experiment. Data was statistically analyzed through the single-case d-statistic. A clear transient effect of Forbrain^®, when turned on, was observed on voice quality, supported by significant differences between Baseline and Test, and Test and Post-test in the tilt of the trendline of the long term average spectrum (tLTAS) of the voice. The present single-case study support the effectiveness of Forbrain^® in modifying the voice during stuttering, supporting its role as an AAF device.

Forbrain®在口吃中的潜在应用:一项单例研究

我们提出了一项关于一种新的听觉反馈(AAF)装置(Forbrain®)在口吃中的潜在临床相关性的单例研究。在一项适当控制的单例时间序列(A-B-A)研究中，对一名口吃的成年人进行了测试。在连续六个工作日的每一天，口吃成人被指示在三个不同的实验阶段大声朗读:基线，测试和后测试，同时戴着Forbrain®耳机。在测试阶段，设备是打开的，而在基线和后测试阶段，它是关闭的。这样可以分析Forbrain®的瞬时效应。在实验的每个阶段，从参与者的语音记录中提取了六项语音质量的定量测量。通过单例d统计对数据进行统计分析。在打开Forbrain®时，我们观察到语音质量有明显的瞬态效应，在语音长期平均频谱(tLTAS)趋势线的倾斜方面，基线和测试以及测试和后测试之间存在显著差异。目前的单例研究支持Forbrain®在口吃期间改变声音的有效性，支持其作为AAF设备的作用。

期刊介绍： The Anuario de Psicología, one of Spain"s most important general psychology journals, is published by the Faculty of Psychology of the University of Barcelona. It appears three times a year. The Anuario combines continuity with the past with a strong commitment to the present and the future. The journal is broad-ranging, interdisciplinary, and innovative. The Anuario publishes research reports and applied studies in all fields of psychology. We also accept theorical, epistemological studies, organize dossiers on topical themes, and hold debates on controversial subjects deriving from a central article.
