There have been some controversies over the ability of individuals with autism spectrum disorder (ASD) to perceive biological motion. In this study, we used electroencephalography and behavioural measures (recognition test) to examine whether or not children with ASD can correctly identify biological motion.
Twenty participants with ASD (mean = 11.3, SD = 2.1 years) and 20 typically developed (TD) participants (mean = 11.4, SD = 2.8 years) participated in the study. They watched videos and point light displays of actions, and their EEG was recorded. Then they answered action recognition test, and their accuracy and response times were recorded.
Our findings showed that children with ASD had the same mu suppression as a TD age-matched control group in both point light display and video presentations. Furthermore, the results showed that while TD and ASD groups did not differ in accuracy, ASD participants had a slower reaction time.
Taken together, our results indicate that the perception of non-emotional BMs is preserved in children with ASD.
个体是否具有自闭症谱系障碍（ASD）的生物运动知觉能力一直存在争议。本研究采用脑电图和行为测量（识别测试）来检验 ASD 儿童是否能够正确识别生物运动。
20 名 ASD 儿童（平均年龄=11.3 岁，标准差=2.1 岁）和 20 名正常发育（TD）儿童（平均年龄=11.4 岁，标准差=2.8 岁）参与了本研究。他们观看了动作的视频和点光显示，并记录了他们的脑电图。然后，他们回答了动作识别测试，并记录了他们的准确性和反应时间。
我们的研究结果表明，在点光显示和视频演示中，ASD 儿童与 TD 年龄匹配的对照组具有相同的 mu 抑制。此外，结果表明，TD 组和 ASD 组在准确性上没有差异，但 ASD 参与者的反应时间较慢。
总的来说，我们的研究结果表明，非情感性生物运动的感知在 ASD 儿童中是保留的。
