Document Summary

Object perception concerns our ability to visually identify the world around us. Object agnosia- an acquired deficit in identifying and recognizing objects even though vision remains intact. This sensory deficit occurs without any loss of sensation. Patient could not identify simple objects, despite the fact that he could see them and he could describe them accurately. It is the result of damage to the interotemporal cortex. Our ability to detect objects must overcome 3 aspects of the environment: To overcome image clutter we must: discern the object despite the overlapping presence of nearby objects. In object variety , we must recognize a particular object as a member of particular class or category, despite small or large differences from our general prototype of that category. In variable views, we must recognize an object despite its being placed in very different orientations relative to ourselves and casting different images onto our retinae.
