虽然感觉问题，包括不寻常的触觉敏感性，与自闭症密切相关，但缺乏严格的心理物理研究。我们比较了触觉在成人自闭症控制手掌和前臂，后者受低阈值无髓鞘传入subserving社会/亲和的躯体感觉亚模态。在这两个地点，这两组显示出类似的阈值检测轻触和无害的感觉温暖和凉爽，并提供了类似的享乐评级的愉快的纹理。相比之下，自闭症组的前臂对振动的敏感性增加，沿着两个部位对热痛的敏感性增加。这些发现表明，自闭症患者的感知沿着而增强，这与之前的研究一致。
Although sensory problems, including unusual tactile sensitivity, are heavily associated with autism, there is a dearth of rigorous psychophysical research. We compared tactile sensation in adults with autism to controls on the palm and forearm, the latter innervated by low-threshold unmyelinated afferents subserving a social/affiliative submodality of somatosensation. At both sites, the groups displayed similar thresholds for detecting light touch and innocuous sensations of warmth and cool, and provided similar hedonic ratings of the pleasantness of textures. In contrast, increased sensitivity to vibration was seen in the autism group on the forearm, along with increased sensitivity to thermal pain at both sites. These findings suggest normal perception along with certain areas of enhanced perception in autism, consistent with previous studies.
