自闭症谱系障碍（ASD）患者对与人类有关的社会信息的感知和取向存在缺陷，一些自闭症谱系障碍患者对类人机器人的偏好高于其他人类。我们推测，ASD患者的这种行为偏见是由他们对人性感知的弱点引起的。为了解决这个问题，我们调查了ASD患者是否能察觉到人类和人造声音唱的同一首歌之间的细微差异，即使歌词、旋律和节奏都是相同的。没有自闭症的人回答说，人声演唱的歌曲比人声演唱的歌曲更能唤起人的感觉（像人、动物性、自然性、情感）和更积极的感觉（温暖、熟悉、舒适）。相比之下，ASD患者对人声和人声演唱的歌曲有着相似的人性印象和积极的感觉。对音乐特征（复杂性、规律性、亮度）的评估在自闭症患者和非自闭症患者之间没有差异。这些结果表明，ASD患者感知人类心理属性的能力较弱。(C) 2016 Elsevier B.V.版权所有
People with autism spectrum disorder (ASD) exhibit impairments in the perception of and orientation to social information related to humans, and some people with ASD show higher preference toward human-like robots than other humans. We speculated that this behavioural bias in people with ASD is caused by a weakness in their perception of humanness. To address this issue, we investigated whether people with ASD detect a subtle difference between the same song sung by human and artificial voices even when the lyrics, melody and rhythm are identical. People without ASD answered that the songs sung by a human voice evoked more impressions of humanness (human-likeness, animateness, naturalness, emotion) and more positive feelings (warmth, familiarity, comfort) than those sung by an artificial voice. In contrast, people with ASD had similar impressions of humanness and positive feelings for the songs sung by the human and artificial voices. The evaluations of musical characteristics (complexity, regularity, brightness) did not differ between people with and without ASD. These results suggest that people with ASD are weak in their ability to perceive psychological attributes of humanness. (C) 2016 Elsevier B.V. All rights reserved.
