人们已经广泛地表明，人类观察者能够通过观察举重者动作的点光显示来感知举起的重量。在这里报道的实验中，被观察者用来感知举起的重物的运动学信息被确定。在实验1中，观察者（N = 30）能够通过仅观察动作的举举阶段成功地识别重量（5,10,15,20和25kg）。其他的方法，比如拿着重物走路和把重物放在桌子上，并没有显著地改善估计。在实验2中，研究了4名举重运动员的运动模式，他们的体重从5公斤到25公斤不等。提升重量的变化导致提升速度、髋部角度和停留时间的变化。在实验3中，有15名观察者参与，对这3个运动变量进行实验操作。结果表明，观测结果受升力速度变化的影响最为显著。讨论了与动力学的运动学规范和启发式方法有关的结果。
It has been widely shown that human observers are able to perceive lifted weight from the observation of a point-light display of the lifter's action. In the experiments reported here, the kinematic information used by observers to perceive a lifted weight was determined. In Experiment 1, observers (N = 30) were able to identify weights (5, 10, 15, 20, and 25 kg) successfully by observing only the lift phase of the action. Other procedures, such as walking while holding the weight and placing the weight on a table, did not result in significantly improved estimations. In Experiment 2, the kinematic patterns used by 4 lifters with weights varying from 5 to 25 kg were examined. Changes in weight lifted resulted in changes in lift velocity, hip angle, and dwell time. In Experiment 3, in which 15 observers participated, these 3 kinematic variables were experimentally manipulated. The results indicated that observation was most significantly influenced by variations in lift velocity. The results are discussed in relation to kinematic specification of dynamics and heuristic approaches.
