Current views suggest that autism spectrum disorders (ASDs) are characterised by enhanced low-level auditory discrimination abilities. Little is known, however, about whether enhanced abilities are universal in ASD and how they relate to symptomatology. We tested auditory discrimination for intensity, frequency and duration in 21 adults with ASD and 21 IQ and age-matched controls. Contrary to predictions, there were significant deficits in ASD on all acoustic parameters. The findings suggest that low-level auditory discrimination ability varies widely within ASD and this variability relates to IQ level, and influences the severity of restricted and repetitive behaviours (RRBs). We suggest that it is essential to further our understanding of the potential contributing role of sensory perception ability on the emergence of RRBs.
当前观点认为，自闭症谱系障碍（ASD）的特征是低水平听觉辨别能力增强。然而，对于这种增强的能力在ASD中是否普遍存在，以及它们与症状学之间的关系，我们知之甚少。我们对21名患有ASD的成年人以及21名智商和年龄匹配的对照组进行了强度、频率和持续时间的听觉辨别测试。与预测相反，ASD患者在所有声学参数上均存在显著缺陷。研究结果表明，低水平听觉辨别能力在ASD患者中差异很大，这种变异性与智商水平相关，并影响受限和重复行为（RRB）的严重程度。我们认为，进一步了解感官知觉能力对RRB出现的潜在作用至关重要。
