在学龄前时期，面部生物运动感知的发展数据不成比例地稀缺。我们调查了学龄前儿童识别快乐、愤怒和惊讶表情的能力，以及面部生物运动基础上的闭眼面部运动。4岁（n = 18）和5-6岁（n = 19）的儿童，和成人（n = 17）参加了匹配任务，在该任务中，他们被要求匹配点光显示的面部表情的原型示意图的面部表情和面部运动。结果显示，从生物运动中识别面部表情的能力早在4岁时就出现了。这种能力在4岁的时候就表现出了明显的快乐表情; 5 - 6岁的孩子可靠地识别出了惊讶和快乐的表情。讨论了这些发现的理论意义。
Data oil the development of the perception of facial biological motion during preschool years are disproportionately scarce. We investigated the ability of preschoolers to recognise happy, angry, and surprised expressions, and eye-closing facial movements oil the basis of facial biological motion. Children aged 4 years (n = 18) and 5-6 years (n = 19), and adults (n = 17) participated in a matching task, in which they were required to match the point-light displays of facial expressions to prototypic schematic images of facial expressions and facial movement. The results revealed that the ability to recognise facial expressions from biological motion emerges as early as the age of 4 years. This ability was evident for happy expressions at the age of 4 years; 5 - 6-year-olds reliably recognised surprised as well as happy expressions. The theoretical significances of these findings are discussed.
