Autism spectrum disorder (ASD) is characterised by differences in unimodal and multimodal sensory and proprioceptive processing, with complex biases towards local over global processing. Many of these elements are implicated in versions of the rubber hand illusion (RHI), which were therefore studied in high-functioning individuals with ASD and a typically developing control group. Both groups experienced the illusion. A number of differences were found, related to proprioception and sensorimotor processes. The ASD group showed reduced sensitivity to visuotactile-proprioceptive discrepancy but more accurate proprioception. This group also differed on acceleration in subsequent reach trials. Results are discussed in terms of weak top-down integration and precision-accuracy trade-offs. The RHI appears to be a useful tool for investigating multisensory processing in ASD.
自闭症谱系障碍（ASD）的特点是在单一模态和多模态感觉和本体感觉处理方面存在差异，表现为复杂的偏向于局部加工而非整体加工的偏好。这些元素中的许多都与橡胶手错觉（RHI）有关，因此在高功能 ASD 个体和典型发育对照组中研究了这些元素。两个组都经历了错觉。发现了一些与本体感觉和感觉运动过程有关的差异。ASD 组对视觉触觉本体感觉差异的敏感性降低，但本体感觉更准确。该组在后续的伸手试验中加速度也不同。结果从自上而下的整合较弱和精度准确性权衡的角度进行了讨论。RHI 似乎是研究 ASD 中多感觉处理的有用工具。
