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.
自闭症谱系障碍（ASD）是一种普遍存在的发育障碍，包括感知加工异常。我们在一系列测试中测量感知能力，包括语音（滤波、音位分类、多感觉整合）和音乐（音高记忆、节奏分类、和声启动）。我们发现，与对照组相比，ASD 组的滤波能力较差，视听整合能力较弱，对母语音位和节奏类别特异性较差，绝对音高较高。在和声启动方面，两组没有差异。我们的结果在发展框架中进行了讨论，在这个框架中，与后期获得的知识相比，早期获得的文化特异性知识受到的损害最大，这可能是因为 ASD 患者的大脑早期加速生长。这些结果表明，早期进行听觉矫正对于良好的沟通和社交功能是必要的。
