在一组11名不同程度语言障碍的患者中测试单词和非单词阅读能力。对于受损最轻的患者，字素-音素关联的概率影响非词阅读能力。一个优势阅读非字，听起来像字（假同音异义词）被发现为6名患者，是无关的患者的非词汇阅读障碍的严重程度。所有的病人都表现出对非词汇阅读所必需的三个加工成分的损害。一项针对五名轻度受损受试者的语音处理能力的研究发现，片段大小和词汇性对患者联合收割机听觉呈现的声音片段的能力有不同的影响。结果被解释为表明多个来源的损害，专门支持非词汇阅读的认知操作的数量。
Word and nonword reading ability was tested in a group of 11 patients with varying levels of language impairments. For the least impaired patients, the probability of grapheme-phoneme association affected nonword reading ability. An advantage reading nonwords that sound like words (pseudo-homophones) was found for six patients, and was unrelated to the severity of patients' nonlexical reading impairments. All patients showed evidence of impairment to all three processing components hypothesised to be necessary for nonlexical reading. A focused study of the phonological processing abilities of the five subjects with mildest impairment uncovered differential influences of segment size and lexicality on patients' ability to combine aurally-presented sound segments. Results are interpreted as indicating multiple sources of impairment to a number of cognitive operations that are specialised to support nonlexical reading.
