80 adults (40 men and 40 women) aged 18 to 25 yr. and 80 boys aged 14 to 15 yr. observed a throwing action presented in point-light form at a frontoparallel viewpoint either as a video film or computer simulation of the actor. The display consisted of the relative motion of the wrist, elbow, and shoulder joints of the throwing arm. Subjects were asked to report what they observed. The action was recognised immediately by 68% of all subjects, and this value increased to 90% with one more viewing of the demonstration. Response was virtually the same for both types of display, and there were no differences between adults and children. The results were similar to those from other studies from which researchers have concluded that kinematic information alone is sufficient to permit perception of fundamental patterns of movement.
80名年龄在18至25岁之间的成年人（40名男性和40名女性）以及80名年龄在14至15岁之间的男孩，以额状面视角观看了以点光源形式呈现的投掷动作，该动作通过视频影片或演员的计算机模拟展示。展示内容包括投掷手臂的手腕、肘部和肩关节的相对运动。受试者被要求报告他们所观察到的内容。所有受试者中有68%能立即识别该动作，再次观看演示后，这一比例升至90%。两种展示类型的反应几乎相同，成年人与儿童之间也没有差异。这些结果与其他研究的结果相似，在其他研究中，研究人员得出结论，仅运动学信息就足以让人感知基本的运动模式。
