An object viewed from different angles can be recognized and distinguished from similar distractors after the viewer has had experience watching it rotate. It has been assumed that as an observer watches the rotation, separate representations of individual views become associated with one another. However, we show here that once monkeys learned to discriminate individual views of objects, they were able to recognize objects across rotations up to 60 degrees , even though there had been no opportunity to learn the association between different views. Our results suggest that object recognition across small or medium changes in viewing angle depends on features common to similar views of objects.
在观察者有过观看物体旋转的经验后，从不同角度观察的物体能够被识别，并与相似的干扰物区分开来。人们一直认为，当观察者观看物体旋转时，各个视图的单独表征会相互关联。然而，我们在此表明，一旦猴子学会辨别物体的各个视图，它们就能识别旋转角度达60度的物体，即便没有机会学习不同视图之间的关联。我们的结果表明，在视角发生中小幅度变化时的物体识别取决于物体相似视图共有的特征。
