通过两个实验来评估3个月大的婴儿对描述人行走的生物力学运动的移动点光显示的处理能力。这些显示是由计算机生成的，根据编码理论的一个版本来衡量，刺激的连贯性各不相同。婴儿控制习惯化范式被用来测量对刺激的编码和辨别。实验一包括两个绝对运动完全相同但相对相干程度不同的点光显示器。结果表明，这两种显示是可区分的，并且编码与它们的相对连贯性有系统的关系。实验2显示，两个相干性变化较小的新显示器也被差异编码，但没有被区分。结论是，婴儿对动态显示的加工随其相对连贯性的不同而变化。
Two experiments were conducted to assess 3-month-old infants'' processing of moving point-light displays depicting the biomechanical motions of a person walking. The displays were computer-generated and varied in stimulus coherence as measured by a version of coding theory. An infant-control habituation paradigm was used to measure both encoding and discrimination of the stimuli. Experiment 1 involved two point-light displays with identical absolute motions but different degrees of relative coherence. The results revealed that these two displays were discriminable and that encoding was systematically related to their relative coherence. Experiment 2 revealed that two new displays varying less in their coherence were also differentially encoded but were not discriminated. It was concluded that infants'' processing of kinetic displays varies as a function of their relative coherence.
