The complex effects of mass and volume on weight perception (e.g., the size-weight illusion) were hypothesized to follow simply from invariants of rotational dynamics. In Experiments 1-3, the rotational inertia of wielded, occluded objects was varied independently of mass, size, and torque. Perceived heaviness depended only on rotational intertia. Reanalysis of J. C. Stevens and L. L. Rubin's (1970) study revealed that size's influence on weight perception depends on specific patterns of the eigenvalues of the inertia tensor. These patterns were simulated in Experiments 4-6 with objects of fixed mass, volume, and visible size. Perceived heaviness decreased and increased, respectively, over object sets with the eigenvalue patterns of (a) constant mass, increasing volume and (b) increasing mass, constant volume. Weight perception and the size-weight illusion depend on stimulus invariants, not inference.
质量和体积对重量感知的复杂影响（例如大小-重量错觉）被假定仅源于旋转动力学的不变量。在实验1-3中，被握持、遮挡物体的转动惯量独立于质量、大小和扭矩而变化。感知到的重量仅取决于转动惯量。对J.C.史蒂文斯和L.L.鲁宾（1970年）研究的重新分析表明，大小对重量感知的影响取决于惯性张量特征值的特定模式。在实验4-6中，使用质量、体积和可见大小固定的物体模拟了这些模式。在具有（a）恒定质量、增加体积和（b）增加质量、恒定体积特征值模式的物体组中，感知到的重量分别降低和增加。重量感知和大小-重量错觉取决于刺激不变量，而非推理。
