It is known that the human brain has a strong preference for rectangularity in interpreting pictures as 3D shapes. Symmetry is also considered to be a factor that the human vision system places high priority on when perceiving 3D objects. Thus, a question is raised: which is more basic, the rectangularity preference or the symmetry preference? To answer this question, we carried out experiments using pictures that have at least two interpretations as 3D objects, one of which was rectangular but not symmetric, and the other of which was symmetric but not rectangular. We found that the preference for rectangularity is stronger than that for symmetry. This observation will help us to understand various 3D optical illusions, including the room-size illusion and the ambiguous object illusion.
众所周知，人类大脑在将图片解读为三维形状时，对矩形有强烈的偏好。对称性也被认为是人类视觉系统在感知三维物体时高度重视的一个因素。因此，产生了一个问题：矩形偏好和对称性偏好，哪一个更基本？为了回答这个问题，我们使用了具有至少两种三维物体解读方式的图片进行实验，其中一种是矩形但不对称，另一种是对称但不是矩形。我们发现，对矩形的偏好比对对称性的偏好更强。这一观察结果将有助于我们理解各种三维视觉错觉，包括房间大小错觉和模糊物体错觉。
