过去二十年的许多实验研究表明，在阅读方面有明显延迟的儿童群体在音素识别和识别方面也表现出弱点。为了进一步研究阅读缺陷类型、听觉敏锐度和言语歧视之间的关系，我们对13名特殊阅读困难儿童、12名时间年龄对照组和12名阅读年龄对照组进行了一系列的言语知觉、心理声学和阅读测试。特殊阅读困难（SRD）儿童的亚组在言语辨别测试中表现不佳，而SRD组的其他儿童在标准范围内表现良好。对于这一亚组，辨别表现特别差的辅音对比不同的单一特征，不是声学上显著的，和问题遇到了鼻音和摩擦对比以及顿音对比。这些孩子在非言语心理声学任务上的表现与对照组没有区别。本文对初级读者在语音处理问题上的音位意识技能进行了评估，这可能有助于理解哪些因素对阅读发展是重要的。
Many experimental studies over the last two decades have suggested that groups of children who suffer significant delay in reading also show a weakness in phoneme discrimination and: identification. In order to look further at the relation between type of reading deficit, auditory acuity, and speech discrimination, a group of 13 children with specific reading difficulty (SRD), 12 chronological-age controls, and 12 reading-age controls were tested on a battery of speech-perceptual, psychoacoustic, and reading tests. A sub-group of children with Specific Reading Difficulty (SRD) were poor at speech discrimination tests, whereas the rest of the SRD group performed within norms. For this sub-group, discrimination performance was particularly poor for consonant contrasts differing in a single feature that was not acoustically salient, and problems were encountered with nasal and fricative contrasts as well as with stop contrasts. These children did not differ from controls in their performance on non-speech psychoacoustic tasks. An evaluation is made of the reported phonemic awareness skills of beginning readers with regard to speech-processing issues which may help in understanding what factors are important in reading development.
