自闭症谱系障碍（ASD）是一种广泛性发育障碍，包括知觉处理异常。我们在一系列测试中测量感知，包括语音（过滤，音素分类，多感官整合）和音乐（音高记忆，节拍分类，谐波启动）。我们发现，与对照组相比，ASD组表现出更差的过滤，更少的视听整合，更少的本地音素和韵律类别的专业化，以及更高的绝对音高的实例。谐波预充无组间差异。我们的研究结果进行了讨论，在发展的框架中，早期获得的文化特定的知识相比，在发展后期是最受损的，也许是因为早期加速的大脑生长在ASD。这些结果表明，早期听觉补救是需要良好的沟通和社会功能。
Autism Spectrum Disorder (ASD) is a pervasive developmental disorder including abnormalities in perceptual processing. We measure perception in a battery of tests across speech (filtering, phoneme categorization, multisensory integration) and music (pitch memory, meter categorization, harmonic priming). We found that compared to controls, the ASD group showed poorer filtering, less audio-visual integration, less specialization for native phonemic and metrical categories, and a higher instance of absolute pitch. No group differences were found in harmonic priming. Our results are discussed in a developmental framework where culture-specific knowledge acquired early compared to late in development is most impaired, perhaps because of early-accelerated brain growth in ASD. These results suggest that early auditory remediation is needed for good communication and social functioning.
