众所周知，丘陵的地理倾斜看起来相当夸张。在这里，我们研究的视觉和触觉感知的地理倾斜的表面在全线索条件下达到，并表明，即使这些表面的感知方向是有偏见的。一个夸张的相对于从水平的偏差示出是本跨模态。实验我采用数值估计显示视觉观察表面的效果，同时控制口头数字偏差。实验2表明，即使手动测量显示良好的校准，偏差也存在。实验3控制注视方向。实验4测量了触觉表面的相同偏差。实验5表明，使用角平分的非数值任务也可以观察到偏差。这些结果限制了地理倾斜感知理论，似乎与偏离水平的功能尺度扩展最一致。
The geographical slants of hills are known to appear quite exaggerated. Here, we examine the visual and haptic perception of the geographical slant of surfaces within reach under full-cue conditions and show that the perceived orientation of even these surfaces is biased. An exaggeration with respect to deviations from horizontal is shown to be present cross-modally. Experiment I employed numerical estimation to show the effect for visually observed surfaces, while controlling for verbal numerical bias. Experiment 2 demonstrated that the bias is present even when manual measures show good calibration. Experiment 3 controlled for direction of gaze. Experiment 4 measured the same bias for haptic surfaces. Experiment 5 showed that the bias can also be observed using the nonnumeric task of angle bisection. These results constrain theories of geographical slant perception and appear most consistent with functional scale expansion of deviations from horizontal.
