In order to recognize an object, the visual system must make abstraction of proximal stimulus variations concomitant with the incidental vantage point. Theoretical models can be distinguished according to the degree to which they require the achievement of viewpoint independence prior to matching a stored object model. Recognition-by-components is one theory which incorporates the realization of general viewpoint invariance as one of its hallmarks. Some aspects of this theory, especially the orientation independence of the represented relations between object parts, are scrutinized. Next, an alternative approach is sketched in which object recognition is accomplished on the basis of a stimulus description which is dependent on the object's orientation, but which makes abstraction of other stimulus variations. Relevant neurophysiological findings are discussed, as well as behavioural evidence from experiments investigating orientation-dependent priming effects in the perception of biological motion.
为了识别一个物体，视觉系统必须从与偶然的观察点相伴的近端刺激变化中进行抽象。理论模型可以根据它们在匹配存储的物体模型之前需要实现视点独立性的程度来区分。部件识别理论是其中一种将实现一般视点不变性作为其标志之一的理论。该理论的一些方面，特别是物体部分之间所表示关系的方向独立性，受到了审视。接下来，概述了一种替代方法，其中物体识别是基于一种依赖于物体方向的刺激描述来完成的，但这种描述对其他刺激变化进行了抽象。讨论了相关的神经生理学发现，以及来自研究生物运动感知中方向依赖启动效应的实验的行为证据。
