质量和体积对重量感知的复杂影响(例如，大小-重量错觉)被假设为简单地从旋转动力学的不变量推导而来。在实验1-3中，被握持、被遮挡的物体的转动惯量与质量、大小和扭矩无关。感觉到的重量只取决于转动惯量。对J·C·史蒂文斯和L·L·鲁宾(1970)研究的重新分析表明，尺寸对体重知觉的影响取决于惯性张力器特征值的特定模式。这些图案是在实验4-6中用固定质量、体积和可见大小的物体模拟的。在具有(A)恒定质量、增大体积和(B)增大质量、恒定体积的特征值模式的对象集合上，感知的重量分别减小和增加。体重知觉和体型-体重错觉依赖于刺激不变量，而不是推理。
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 inertia. 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 tenser. 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.
