Autism spectrum disorders (ASD) are often characterized by atypical sensory behavior (hyper- or hyporeactivity) although evidence is scarce regarding olfactory abilities in ASD; 16 adults with high-functioning ASD (mean age: 38.2, SD: 9.7) and 14 healthy control subjects (mean age: 42.0 years, SD: 12.5) were assessed in odor threshold, free and cued odor identification, and perceived pleasantness, intensity, and edibility of everyday odors. Although results showed no differences between groups, the Bayes Factors (close to 1) suggested that the evidence for no group differences on the threshold and identification tests was inconclusive. In contrast, there was some evidence for no group differences on perceived edibility (BF = 2.69) and perceived intensity (BF = 2.80). These results do not provide conclusive evidence for or against differences between ASD and healthy controls on olfactory abilities. However, they suggest that there are no apparent group differences in subjective ratings of odors.
自闭症谱系障碍（ASD）通常具有非典型的感觉行为特征（反应过度或反应不足），尽管关于ASD嗅觉能力的证据很少；对16名高功能ASD成年人（平均年龄：38.2岁，标准差：9.7）和14名健康对照者（平均年龄：42.0岁，标准差：12.5）进行了气味阈值、自由和提示气味识别以及日常气味的感知愉悦度、强度和可食用性的评估。虽然结果显示两组之间没有差异，但贝叶斯因子（接近1）表明，在阈值和识别测试中没有组间差异的证据尚无定论。相比之下，有一些证据表明在感知可食用性（BF = 2.69）和感知强度（BF = 2.80）方面没有组间差异。这些结果没有为支持或反对ASD与健康对照者在嗅觉能力上存在差异提供确凿证据。然而，它们表明在气味的主观评分上没有明显的组间差异。
