There have been several proposals for the mechanism by which we are able to recognize an object across a number of viewpoints. Viewpoint-dependent accounts suggest that recognition may be based on an incremental transformation (e.g., mental rotation) strategy, while a variety of viewpoint-independent mechanisms for object recognition have also been proposed. Recent research in neurobiology, based on the two cortical visual systems account, suggest that the processes of viewpoint-dependent and viewpoint-independent object recognition may rely on separate anatomical regions, and that brain lesions may leave patients with selective access to particular types of representation. Evidence from a variety of neuropsychological disorders are reviewed to support the position that viewpoint-independent object recognition depends upon the integrity of occipitotemporal structures. In addition, it is suggested that viewpoint-dependent processes (perhaps depending on occipitoparietal structures) may supplement this primary system under nonoptimal circumstances.
关于我们如何能够从多个视角识别物体的机制，已经有了几种提议。基于视角的解释表明，识别可能基于一种渐进转换（例如，心理旋转）策略，同时也提出了各种与视角无关的物体识别机制。基于两种皮质视觉系统理论的神经生物学最新研究表明，基于视角和与视角无关的物体识别过程可能依赖于不同的解剖区域，并且脑部病变可能使患者只能选择性地获取特定类型的表征。本文回顾了来自各种神经心理障碍的证据，以支持与视角无关的物体识别依赖于枕颞结构完整性的观点。此外，有人认为，在非最佳情况下，基于视角的过程（可能依赖于枕顶结构）可能会补充这个主要系统。
