一个戏剧性的失败的方向恒常性记录在下坡的感知。与天真的期望相反，陡峭的下坡从边缘看起来比从边缘看起来要浅。三个实验文件和量化这种失败的恒定性为真实的和虚拟的表面使用各种相关的措施。另外两项研究记录了非视觉感知的头部俯仰和感知的凝视下降的高估。一个模型的方向恒定性故障是适合的数据相联合收割机的夸大感知的注视decompensation夸大缩放感知的光学倾斜。这些研究结果支持一个功能的规模扩大模型的错误，在斜坡知觉。
A dramatic failure of orientation constancy is documented in the perception of downhill slopes. Contrary to naive expectation, steep downhill slopes look shallower from the edge than they do from back from the edge. Three experiments document and quantify this failure of constancy for real and virtual surfaces using a variety of dependent measures. Two additional studies document overestimation of both non-visually perceived head pitch and perceived gaze declination. A model of orientation constancy failure is fit to the data that combine exaggerations in perceived gaze declination with exaggerated scaling of perceived optical slant. These findings support a functional scale-expansion model of error in slope perception.
