三个实验的影响，密度和直径的触觉感知杆长度的报告。在实验1中，受试者挥舞着不同密度的视觉闭塞杆。感知长度被认为是由杆的密度的影响，无论实际长度。在实验2中，三个不同长度的铝杆与四个不同直径的手柄挥舞。随着手柄直径的增加，棒的感知长度变短。由此产生了直径长度的错觉。在实验3中，用右手挥动直径不同但绕x轴转动惯量相同的视觉闭塞杆，用左手感觉不同直径的管。受试者被告知他们的右手抓住手柄，并且可以用左手感觉到棒的实际直径。如果用左手感觉到直径较大，则认为棒较短。结果表明，感知长度不只是实际杆长的函数，它不是由惯性只占。结果进一步讨论了不变量的性质和感知知识的影响。
Three experiments on the effect of density and diameter on haptic perception of rod length are reported. In Experiment 1, the subjects wielded visually occluded rods of different densities. Perceived length was found to be affected by the density of the rod regardless of the actual length. In Experiment 2, three aluminum rods of different lengths with handles of four different diameters were wielded. Perceived length of the rod was found to be shorter as the diameter of the handle with which it was wielded increased. A diameter—length illusion was thereby produced. In Experiment 3, visually occluded rods of different diameters but of the same moment of inertia about thex-axis were wielded with the right hand, and tubes of different diameters were felt with the left hand. The subjects were instructed that their right hand was grasping a handle, and that the actual diameter of the rod could be felt with the left hand. Rods were perceived to be shorter if a larger diameter was felt with the left hand. The results showed that perceived length is not just a function of actual rod length, and that it is not accounted for by inertia only. The results are further discussed in terms of the nature of invariants and the effect of knowledge on perception.
