DIFFERENT PROCESSES FOR ENUMERATING ELEMENTS OF OBJECTS AND SCENES Anthony Cate Department of Psychology Carnegie Mellon University Abstract These experiments examined healthy subjects' abilities to enumerate cylinders that were either parts of the same object or different objects. The results indicate that objects and scenes are processed in fundamentally different ways, even when the object and scene stimuli are highly similar, and even for a relatively simple task. When the cylindrical elements were separate objects ("scenes"), performance declined with greater numbers of elements, suggesting that each element was represented individually. When they were part of the same object ("objects"), the enumeration judgments appeared to be based on categorical judgments (i.e. "many" or "few"). Furthermore, learned expertise in making the enumeration judgment was exemplar-specific for the object stimuli, but generalized to new exemplars for the scene stimuli.
