Runeson和Frykholm（1981,1983）发现，观察者可以判断另一个人举起的重量，当只有运动在patch-light显示器中可见时。Gilden和Proffitt（1989）认为这可能是实验性的人工制品。其中包括一个标准，可以用来衡量感知到的运动和举起的重量。标准对结果至关重要吗？我们进行了实验，以调查显示的作用，一个标准，触觉经验的已知重量，以及有关升降机尺寸的信息。结果表明，已知重量和标准的触觉经验在减少随机误差方面是相同的，但标准不同于触觉信息，它产生收缩效应，增加了系统误差。没有标准的结果与Runeson和Frykholm的结果相当。观察人员还对三个不同体型的举重运动员的表演进行了评判，每个人举起的最大重量都相当于他们体型的三分之一。升降机尺寸的静态信息是受控的，没有使用标准。结果表明，吊重结果不是实验伪影。
Runeson and Frykholm (1981, 1983) discovered that observers could judge the amount of weight lifted by another person when only the motions were visible in patch-light displays. Gilden and Proffitt (1989) suggested that this might have been experimental artifact. A standard had been included and might have been used to scale perceived motions to amounts of lifted weight. Were standards essential to the results? We performed experiments to investigate the role of the displays, of a standard, of haptic experience of a known weight, and of information about lifter size. The results demonstrated that haptic experience of a known weight and standards were equivalent in reducing random errors, but that standards, unlike haptic information, produced a contraction effect that increased systematic errors. Results without a standard were comparable to those of Runeson and Frykholm.Observers also judged displays of three different-size lifters, each lifting maximum weights equal to a third of their body size. Static information for lifter size was controlled and no standard was used. Results demonstrate that the lifted-weight result is not experimental artifact.
