Spurger综合征（AS）的特征是语言发育正常，但对语音语调和韵律的理解和使用不足。虽然患有AS的个体报告在听觉感知方面存在困难，但没有研究涉及感觉水平的听觉处理。在这项研究中，事件相关电位（ERP）记录音节和音调在儿童与AS和他们的对照组。AS儿童表现出异常的瞬态声音特征编码，作为索引的强制性ERP，并在声音的歧视，作为索引的不匹配负性。这些赤字更严重的音调刺激比音节。这些结果表明，听觉感觉处理是缺乏儿童AS，这些赤字可能涉及的知觉问题所遇到的儿童AS。(C)2002爱思唯尔科学爱尔兰有限公司保留所有权利。
Asperger Syndrome (AS) is characterized by normal language development but deficient understanding and use of the intonation and prosody of speech. While individuals with AS report difficulties in auditory perception, there are no studies addressing auditory processing at the sensory level. In this study, event-related potentials (ERP) were recorded for syllables and tones in children with AS and in their control counterparts. Children with AS displayed abnormalities in transient sound-feature encoding, as indexed by the obligatory ERPs, and in sound discrimination, as indexed by the mismatch negativity. These deficits were more severe for the tone stimuli than for the syllables. These results indicate that auditory sensory processing is deficient in children with AS, and that these deficits might be implicated in the perceptual problems encountered by children with AS.
