Rabbits were trained to discriminate patterns consisting of straight bars and rows of dots of different orientation. It was found that using proximal pattern presentation, at a distance of 5 cm in front of the animal, dot rows of different orientation are not discriminated on the basis of tilt extrapolation, but by the use of regional cues.
训练兔子辨别由不同方向的直条和点状行组成的图案。结果发现，在动物前方5厘米的近距离呈现图案时，兔子不是基于倾斜外推来辨别不同方向的点状行，而是利用局部线索。
