前言音节重音的感知在发展性阅读障碍中还没有得到广泛的研究，尽管有强有力的证据表明听觉节奏感知困难。在这里，我们研究了发展性阅读障碍成年人对声音上升时间的感知与音节重音的感知有关的假设。设计了不同的压力感知任务，并以两种形式对40名成年人进行了测试，一种是使用成对的相同的4-结果阅读障碍者在两种重音知觉任务中的表现均显著低于对照组，差异有统计学意义（P < 0.05），差异有统计学意义（P < 0.01），差异有统计学意义（P < 0.05），差异有统计学意义（P < 0.01），差异有统计学意义（P < 0.05），差异有统计学意义（P < 0.05结论：据我们所知，这是第一次直接证明音节重音知觉缺陷的阅读障碍，语调模式和节奏的准确感知可能是至关重要的语音词汇的发展，从而为识字的发展，即使是高功能代偿的成人阅读障碍显示损害的语音处理（C）2010爱思唯尔公司版权所有
Introduction The perception of syllable stress has not been widely studied in developmental dyslexia despite strong evidence for auditory rhythmic perceptual difficulties Here we investigate the hypothesis that perception of sound rise time is related to the perception of syllable stress in adults with developmental dyslexiaMethods A same-different stress perception task was devised and delivered to a sample of 40 adults in two formats one using pairs of identical 4-syllable words and one using pairs of two different 4 syllable words Auditory perception of rise time frequency and intensity and phonological awareness phonological memory and reading were also measuredResults We show that adults with dyslexia performed significantly more poorly in both versions of the stress perception task Individual differences in the perception of rise time were linked to the accuracy of performanceConclusions To our knowledge this is the first direct demonstration of syllable stress perception deficits in dyslexia The accurate perception of intonational patterning and rhythm may be critical for the development of the phonological lexicon and consequently for the development of literacy Even high functioning compensated adults with dyslexia show impairments in speech processing (C) 2010 Elsevier Inc All rights reserved
