Interpersonal distance (IPD) is a simple social regulation metric which is altered in autism. We performed a stop-distance paradigm to evaluate IPD regulation in autism spectrum disorder (ASD) and control groups in a real versus a virtual environment mimicking in detail the real one. We found a bimodal pattern of IPDs only in ASD. Both groups showed high IPD correlations between real and virtual environments, but the significantly larger slope in the control group suggests rescaling, which was absent in ASD. We argue that loss of nuances like non-verbal communication, such as perception of subtle body gestures in the virtual environment, lead to changed regulation of IPD in controls, whilst ASD participants show similar deficits in perceiving such subtle cues in both environments.
人际距离（IPD）是一种简单的社会调节度量标准，在自闭症中会发生变化。我们进行了停止距离范式，以评估自闭症谱系障碍（ASD）和对照组在真实与详细模拟真实环境的虚拟环境中的 IPD 调节。我们发现只有在 ASD 中才存在 IPD 的双峰模式。两组在真实和虚拟环境之间都显示出高度的 IPD 相关性，但是对照组的斜率明显更大，表明存在重新缩放，而 ASD 组则没有。我们认为，像非言语交流这样的细微差别，例如在虚拟环境中感知微妙的身体姿势的能力的丧失，会导致对照组的 IPD 调节发生变化，而 ASD 参与者在两个环境中都表现出类似的感知这种细微线索的缺陷。
