Deficits in auditory short-term memory have been widely reported in children with Specific Language Impairment (SLI), and recent evidence suggests that children with Autism Spectrum Disorder and co-morbid language impairment (ALI) experience similar difficulties. Music, like language relies on auditory memory and the aim of the study was to extend work investigating the impact of auditory short-term memory impairments to musical perception in children with neurodevelopmental disorders. Groups of children with SLI and ALI were matched on chronological age (CA), receptive vocabulary, non-verbal intelligence and digit span, and compared with CA matched typically developing (TD) controls, on tests of pitch and temporal acuity within a voluntary musical imagery paradigm. The SLI participants performed at significantly lower levels than the ALI and TD groups on both conditions of the task and their musical imagery and digit span scores were positively correlated. In contrast ALI participants performed as well as TD controls on the tempo condition and better than TD controls on the pitch condition of the task. Whilst auditory short-term memory and receptive vocabulary impairments were similar across ALI and SLI groups, these were not associated with a deficit in voluntary musical imagery performance in the ALI group.
特定语言障碍（SLI）儿童中广泛存在听觉短期记忆缺陷，最近有证据表明，患有自闭症谱系障碍和共病语言障碍（ALI）的儿童也有类似的困难。音乐和语言一样依赖听觉记忆，该研究的目的是将调查听觉短期记忆障碍影响的工作扩展到神经发育障碍儿童的音乐感知方面。将患有SLI和ALI的儿童组在实际年龄（CA）、接受性词汇、非言语智力和数字广度方面进行匹配，并与CA匹配的典型发育（TD）对照组在自愿音乐意象范式下的音高和时间敏锐度测试中进行比较。在任务的两种条件下，SLI参与者的表现均显著低于ALI组和TD组，并且他们的音乐意象和数字广度得分呈正相关。相比之下，ALI参与者在节奏条件下的表现与TD对照组一样好，在任务的音高条件下比TD对照组表现更好。虽然ALI组和SLI组的听觉短期记忆和接受性词汇障碍相似，但这些与ALI组的自愿音乐意象表现缺陷无关。
