| | Visual Categorization in Pigeons |
 | | Categorization can be viewed as the ability to treat similar, but not identical, things as somehow equivalent, by sorting them into their proper categories and by reacting to them in the same manner (Rosch, 1978; Medin and Smith, 1984; Harnard, 1987; Neisser, 1987). |
 | | It would lead to a regrettable underestimation of their competencies if they were interpreted as simple categorization and, at the same time, to an overestimation of the distinctiveness of those processes that give rise to the bottleneck solutions found in many other species. |
 | | Despite the common tenet that categorization is not a logical device, but a matter of assessing similarity, there is little agreement concerning the level of abstraction from which the descriptors of open-ended categories are obtained. |
