Morales等人（1）表明，与旋转的圆相比，面向前方的椭圆在面向前方的圆中更快地被识别出来，这使他们得出结论，视觉具有双重特征：旋转的圆被视为透视二维（2D）椭圆和3D圆。我们有两个担忧。
首先，这是测试感知形状吗？Morales等人（1）将透视等同于感知的2D形状，但另一种思考透视的方式是3D视觉方向。旋转的3D圆的边缘和面向前方的2D椭圆具有相同的3D视觉方向，即使视觉系统已经完全恢复了圆的3D形状。这不是...

Morales et al. (1) show that a front-facing ellipse is more quickly identified among front-facing circles than rotated circles, leading them to conclude that vision has a dual character: A rotated circle is perceived both as a perspectival two-dimensional (2D) ellipse and as a 3D circle. We have two concerns.
First, is this testing perceived shape? Morales et al. (1) equate perspective with perceived 2D shape, but another way of thinking about perspective is 3D visual direction. The edge of a rotated 3D circle and a front-facing 2D ellipse have the same 3D visual direction even if the visual system has fully recovered the circle’s 3D shape. This isn’t …
