Recognizing objects seen from novel viewpoints: effects of view similarity and time.
View combination refers to a process that allows generalization to novel views of an object by the combination of object views represented in memory. The present experiments examined whether the perceived similarity between views or the temporal separation of views poses constraints on the view combination process. The results indicated that, although similar views are mapped onto the same object more easily than dissimilar views, dissimilar views, when experienced contiguously in time, produce greater generalization after view combination than similar views. These findings suggest that although the mapping of dissimilar views to the same object is difficult, exposure to temporally contiguous dissimilar views produces better generalization than does exposure to similar views, presumably because they provide more structural information about the object. However, view combination appears to be constrained to views experienced contiguously in time.
