Abstract

Previous work has demonstrated a difference in human sensitivity to compressive and shearing speed gradients. This raises the possibility that the ability to estimate the slant of a surface may vary with its direction of tilt. No such variance was found here, which may indicate that slant estimation depends upon deformation rather than upon compression or shear.

摘要

先前的研究表明，人类对压缩和剪切速度梯度的敏感度存在差异。这就增加了一种可能性，即估计表面倾斜度的能力可能会因其倾斜方向而有所不同。但在本研究中未发现这种差异，这可能表明倾斜度估计取决于变形而非压缩或剪切。
