Visual perception in individuals with autism spectrum disorder (ASD) is often debated in terms of enhanced local and impaired global perception. Deficits in global motion perception seem to support this characterization, although the evidence is inconsistent. We conducted a large meta-analysis on global motion, combining 48 articles on biological and coherent motion. Results provide evidence for a small global motion processing deficit in individuals with ASD compared to controls in both biological and coherent motion. This deficit appears to be present independent of the paradigm, task, dependent variable, age or IQ of the groups. Results indicate that individuals with ASD are less sensitive to these types of global motion, although the difference in neural mechanisms underlying this behavioral difference remains unclear.
自闭症谱系障碍（ASD）个体的视觉感知常被认为是局部增强而全局受损。整体运动感知的缺陷似乎支持了这种特征，但证据并不一致。我们对整体运动进行了一项大型元分析，综合了 48 篇关于生物运动和连贯运动的文章。结果表明，与对照组相比，ASD 个体在生物运动和连贯运动中都存在较小的整体运动处理缺陷。这种缺陷似乎独立于范式、任务、因变量、年龄或组间智商。结果表明，ASD 个体对这些类型的整体运动的敏感性较低，尽管这种行为差异背后的神经机制仍不清楚。
