An experimental comparison of viewpoint-specific and viewpoint-independent models of object representation

Article Abstract:

Four experiments were used to investigate the influence of viewpoint on the cognitive representation and subsequent recognition of objects. Rotating objects during recognition tasks resulted in a significant decrease in performance. These findings suggest that object representations are specific to learned viewpoints.
