失语症影响至少三分之一的中风幸存者，并且越来越多的人意识到，听觉处理中更基本的缺陷可能导致这些人的语言表现受损。我们进行了一个全面的电池的心理声学任务评估的感知音调对和序列的领域的音高，节奏和音色在17个人与中风后失语症和17个控制。在个体差异的水平上，我们证明了韵律模式（节拍）感知和语音输出流畅性之间的相关性具有强烈的影响（斯皮尔曼的rho = 0.72）。这与更基本的听觉时间感知无关，而听觉时间感知与输出流畅性无关。这在语言和认知测量方面也是具体的，其中语音，语义和执行功能与节拍检测无关。我们解释的数据的韵律结构的声音构建流畅的输出分析的要求，都是高阶的“时间脚手架”的功能。本文中的搏动感知任务允许测量时序分析而无需考虑运动输出缺陷，并且可以是检查这一点的潜在临床工具。这项工作提出了策略，以提高流畅性中风后的训练，在韵律模式的看法。
Aphasia affects at least one third of stroke survivors, and there is increasing awareness that more fundamental deficits in auditory processing might contribute to impaired language performance in such individuals. We performed a comprehensive battery of psychoacoustic tasks assessing the perception of tone pairs and sequences across the domains of pitch, rhythm and timbre in 17 individuals with post-stroke aphasia and 17 controls. At the level of individual differences we demonstrated a correlation between metrical pattern (beat) perception and speech output fluency with strong effect (Spearman’s rho = 0.72). This dissociated from more basic auditory timing perception, which did not correlate with output fluency. This was also specific in terms of the language and cognitive measures, amongst which phonological, semantic and executive function did not correlate with beat detection. We interpret the data in terms of a requirement for the analysis of the metrical structure of sound to construct fluent output, with both being a function of higher-order “temporal scaffolding”. The beat perception task herein allows measurement of timing analysis without any need to account for motor output deficit, and could be a potential clinical tool to examine this. This work suggests strategies to improve fluency after stroke by training in metrical pattern perception.
