语音技能，语言能力和识字成绩进行了比较，为四组：19名儿童轻度至中度感音神经性听力损失（SNH），20名儿童与特定的语言障碍（SLI），20名对照组匹配的实足年龄SNH组（CA），和15名对照组匹配的接受词汇水平的一个子集的SLI组（CB）。与SLI组一样，轻度至中度听力损失儿童的平均分数在语音短期记忆和语音辨别测试中显着较差。和语音意识。SNH和CA对照组在词汇、数字和句子回忆方面的组平均值没有观察到差异。句子理解和读写成绩。然而，在SNH组中存在相当大的个体差异。近50%的SNH组表现出语音障碍与较差的表达和接受词汇和较高的听力阈值比其余的儿童没有语音障碍。在SNH亚组中观察到非词重复缺陷，有和没有语音障碍，并在SLI儿童中观察到类似的幅度。的确. SLI儿童的重复能力较差，只能在语音复杂的非词上与SNH儿童区分开来。总体而言，研究结果表明，在非单词重复和语音障碍的主要问题发生在没有临床显着的赤字，在更广泛的语言和识字能力的儿童轻度至中度感音神经性听力损失。SLI理论的影响进行了讨论。
Phonological skills, language ability, and literacy scores were compared for four groups: 19 children with mild-to-moderate sensorineural hearing loss (SNH), 20 children with specific language impairment (SLI), 20 controls matched on chronological age to the SNH group (CA), and 15 controls matched on receptive vocabulary level to a subset of the SLI group (CB). In common with the SLI group, mean scores of children with mild-to-moderate hearing loss were significantly poorer on tests of phonological short-term memory, phonological discrimination. and phonological awareness than CA controls. No differences between group means were observed in SNH and CA control groups on vocabulary, digit and sentence recall. sentence comprehension, and literacy scores. However, there was considerable individual variation within the SNH group. Nearly 50% of the SNH group showed phonological impairment associated with poorer expressive and receptive vocabulary and higher hearing thresholds than remaining children without phonological impairment. Nonword repetition deficits were observed in SNH subgroups with and without phonological impairment and were of a similar magnitude to those observed in children with SLI. Indeed. poorer repetition in children with SLI could only be differentiated from children with SNH on phonologically complex nonwords. Overall, findings suggested major problems in nonword repetition and phonological impairment occurred without clinically significant deficits in wider language and literacy abilities in children with mild-to-moderate sensorineural hearing loss. Implications for theories of SLI are discussed.
