几十年来，人们一直在争论听觉处理和语言技能之间的关系。之前的发现并不一致，无论是在典型的发育中的受试者还是受损的受试者中，包括那些有诵读困难或特定语言障碍的人。听觉技能和语言技能之间的相关性在不同的人群中是否一致，几乎没有得到解决。目前的工作提出了一种探索性的方法，测试模式的相关性在一系列措施的听觉处理。在最近的一项研究中，我们报告了一大批11岁儿童在一系列听觉测量方面的发现，这些数据支持了短序列在音调和时间上的处理在典型语言发展中的特殊作用。在这里，我们测试了来自同一年组的一组有阅读障碍特征的个体(DT组；n=28)是否会显示出与典型发育组(TD组；n=173)相同的听觉和语言技能之间的相关性模式。至于原始分数，DT组在语言上的表现明显较差，但在听觉测量方面没有表现，包括音调、时间和节奏以及音色(调制)的测量。在相关性方面，短序列加工与语言技能之间的相关性有下降的趋势，而基本的单音加工的相关性显著增加，特别是在调制领域。这些数据支持这样一种观点，即与典型的语言发展相比，听觉技能和语言技能之间的基本关系可能不同于典型的语言发展，这意味着在人群之间合并数据或推断可能是有问题的。进一步研究受损人群的基本声音特征分析和类似音乐的声音分析与语言技能之间的关系，可能有助于制定适当的培训策略。这些可能包括通过声音序列分析的共同基础来增强语言技能的音乐培训类型。本文是题为的特刊的一部分。(C)2013年提交人。爱思唯尔出版，版权所有。
The relationship between auditory processing and language skills has been debated for decades. Previous findings have been inconsistent, both in typically developing and impaired subjects, including those with dyslexia or specific language impairment. Whether correlations between auditory and language skills are consistent between different populations has hardly been addressed at all. The present work presents an exploratory approach of testing for patterns of correlations in a range of measures of auditory processing. In a recent study, we reported findings from a large cohort of eleven-year olds on a range of auditory measures and the data supported a specific role for the processing of short sequences in pitch and time in typical language development. Here we tested whether a group of individuals with dyslexic traits (DT group; n = 28) from the same year group would show the same pattern of correlations between auditory and language skills as the typically developing group (TD group; n = 173). Regarding the raw scores, the DT group showed a significantly poorer performance on the language but not the auditory measures, including measures of pitch, time and rhythm, and timbre (modulation). In terms of correlations, there was a tendency to decrease in correlations between short-sequence processing and language skills, contrasted by a significant increase in correlation for basic, single-sound processing, in particular in the domain of modulation. The data support the notion that the fundamental relationship between auditory and language skills might differ in atypical compared to typical language development, with the implication that merging data or drawing inference between populations might be problematic. Further examination of the relationship between both basic sound feature analysis and music-like sound analysis and language skills in impaired populations might allow the development of appropriate training strategies. These might include types of musical training to augment language skills via their common bases in sound sequence analysis.This article is part of a Special Issue entitled . (C) 2013 The Authors.
