自闭症谱系障碍（ASD）通常与对感官刺激的异常反应有关，这被认为是导致ASD定义的社交，沟通和重复行为缺陷的原因。然而，很少有研究通过单独的感觉模态来分离异常的感觉反应，以评估感觉特征和核心症状之间的模态特异性关联。对触觉刺激的反应差异在ASD中很普遍，婴儿早期的触觉接触是ASD影响的社交和沟通技能发展的基础。我们评估了三种异常的触觉反应模式（高反应，低反应，感觉寻求）和ASD的核心症状之间的关联。感官和核心功能的测量与收敛的方法，包括父母的报告和直接观察。我们的研究结果表明，对于触觉方式，感觉低反应性与增加的社会和沟通障碍，并在较小程度上，重复行为密切相关。研究发现，感觉寻求与社交障碍、非语言沟通障碍和重复行为密切相关。令人惊讶的是，触觉高反应性与ASD的任何核心特征都没有显着相关性。特定触觉处理模式和核心特征之间的这种差异性关联为确定ASD感觉症状的意义提供了重要的一步，并且可能有助于开发基于感觉的早期检测和干预方法。
Autism spectrum disorders (ASD) are often associated with aberrant responses to sensory stimuli, which are thought to contribute to the social, communication, and repetitive behavior deficits that define ASD. However, there are few studies that separate aberrant sensory responses by individual sensory modality to assess modality-specific associations between sensory features and core symptoms. Differences in response to tactile stimuli are prevalent in ASD, and tactile contact early in infancy is a foundation for the development of social and communication skills affected by ASD. We assessed the association between three aberrant patterns of tactile responsiveness (hyper-responsiveness, hypo-responsiveness, sensory seeking) and core symptoms of ASD. Both sensory and core features were measured with converging methods including both parent-report and direct observation. Our results demonstrate that for the tactile modality, sensory hypo-responsiveness correlates strongly with increased social and communication impairments, and to a lesser degree, repetitive behaviors. Sensory seeking was found to correlate strongly with social impairment, nonverbal communication impairment, and repetitive behaviors. Surprisingly, tactile hyper-responsiveness did not significantly correlate with any core features of ASD. This differential association between specific tactile processing patterns and core features provides an important step in defining the significance of sensory symptoms in ASD, and may be useful in the development of sensory–based approaches for early detection and intervention.
