背景生物运动，即他人的运动，传递信息，允许识别情感状态和意图。这使得它成为自闭症谱系障碍研究的重要途径，其中社会功能是主要困难领域之一。我们的目的是创建一个定量总结以前的研究结果，并调查潜在的因素，这可以解释在文献中发现的变量结果调查自闭症的生物运动知觉。方法从5个电子数据库中检索出52篇符合定量总结条件的论文，包括行为学、眼动追踪、脑电图和功能性磁共振成像研究。结果使用三个层次的随机效应荟萃分析方法，我们发现，自闭症患者普遍表现出降低的性能在感知和解释的生物运动。结果还表明，当需要更高阶的信息，如情感，性能下降。此外，随着年龄的增长，自闭症和神经典型个体之间的差异减小，儿童总体上表现出最大的效应量。结论：我们强调需要方法标准和明确的年龄组和范式之间的区别时，试图解释两个人群之间的差异。
Background Biological motion, namely the movement of others, conveys information that allows the identification of affective states and intentions. This makes it an important avenue of research in autism spectrum disorder where social functioning is one of the main areas of difficulty. We aimed to create a quantitative summary of previous findings and investigate potential factors, which could explain the variable results found in the literature investigating biological motion perception in autism. Methods A search from five electronic databases yielded 52 papers eligible for a quantitative summarisation, including behavioural, eye-tracking, electroencephalography and functional magnetic resonance imaging studies. Results Using a three-level random effects meta-analytic approach, we found that individuals with autism generally showed decreased performance in perception and interpretation of biological motion. Results additionally suggest decreased performance when higher order information, such as emotion, is required. Moreover, with the increase of age, the difference between autistic and neurotypical individuals decreases, with children showing the largest effect size overall. Conclusion We highlight the need for methodological standards and clear distinctions between the age groups and paradigms utilised when trying to interpret differences between the two populations.
