先前的研究表明，患有发育性阅读障碍的儿童对语音的分类感知存在缺陷。当前研究的目的是更好地理解这种分类感知缺陷的本质。在这项研究中，将患有阅读障碍的儿童的分类感知技能与同龄和阅读水平对照的儿童进行了比较。孩子们沿着发声时间（VOT）连续体识别和区分/do-to/音节。结果表明，患有阅读障碍的儿童在区分音位对比对时的准确度低于按实际年龄和阅读水平对照的儿童，并且在区分异体对比方面也表现出更高的敏感性。这些结果表明，患有阅读障碍的儿童以异音单位而不是音素单位感知言语。讨论了知觉发展过程中异音知觉的起源及其对阅读习得的影响。 (C) 2008 Elsevier Inc. 保留所有权利。
Previous studies have shown that children suffering from developmental dyslexia have a deficit in categorical perception of speech sounds. The aim of the current study was to better understand the nature of this categorical perception deficit. In this study, categorical perception skills of children with dyslexia were compared with those of chronological age and reading level controls. Children identified and discriminated /do-to/ syllables along a voice onset time (VOT) continuum. Results showed that children with dyslexia discriminated among phonemically contrastive pairs less accurately than did chronological age and reading level controls and also showed higher sensitivity in the discrimination of allophorric contrasts. These results suggest that children with dyslexia perceive speech with allophonic units rather than phonemic units. The origin of allophonic perception in the course of perceptual development and its implication for reading acquisition are discussed. (C) 2008 Elsevier Inc. All rights reserved.
