S. J. Lederman、S. R. Ganeshan 和 R. E. Ellis (1996) 报道了一项实验，证明对于质量和长度相同但直径不同的闭塞杆，静态保持的长度感知对于较小直径的杆来说更大。他们得出的结论是，参与者根据虚幻的重量感知推断了长度。然而，质量和长度相同但直径不同的杆其各自的惯性张量的特征值也不同。在本实验中，作者操纵了静态物体的直径（实验 1）和惯性特征值（实验 4 和 5）。正如挥舞物体所显示的那样，感知长度是特征值的函数。其他实验未能证实重量感知模型的预期，即感知长度映射到估计重量（实验 2 和 3）。物理量，而不是心理量，似乎可以通过静态保持来解释长度感知。
S. J. Lederman, S. R. Ganeshan, and R. E. Ellis (1996) reported an experiment demonstrating that for occluded rods of equal mass and length but different diameters length perception by static holding was larger for rods of smaller diameter. They concluded that participants inferred length from illusory weight percepts. However, rods of equal mass and length that differ in diameter also differ in the eigenvalues of their respective inertia tensors. In the present experiments, the authors manipulated the diameters (Experiment 1) and the inertial eigenvalues (Experiments 4 and 5) of statically held objects. As has been shown with wielded objects, perceived length was a function of the eigenvalues. Additional experiments failed to confirm the expectation from the weight-percept model that perceived length maps to the estimated weight (Experiments 2 and 3). Physical quantities, not psychological quantities, seem to explain length perception by static holding.
