CategorizationExemplar and prototypical categorization and their relationship to typicality
Prototype theory is a concept of learning that suggests certain types of objects are more central to forming mental categories than other types of objects. For example, although people may come to acknowledge there are many types of dogs, a Golden Retriever may seem to be more prototypical of the category of 'dog' than, say, a Chow or a Chihuahua. Prototype theory suggests that first the human mind develops a concept, such as a 'sport,' from more typical examples, like baseball and football, and gradually that conceptual group assimilates less typical examples, like fishing and marathon running, which could also be classified as hobbies or fitness activities. "To cope with an incessant flow of information, humans and other organisms must group their experiences into meaningful categories…the traditional view, dating from the time of Aristotle, is that categories are mentally represented as sets of necessary and sufficient conditions. According to this view, an exemplar is assigned to a category if it satisfies the category's membership conditions" (Dopkins & Gleason, 1997, p.1)
But according to prototype theory, boundaries of categories are more fuzzy and pliable by virtue of necessity (Green, 2000, p.301). It seems an "almost common-sense notion that, as an organism, what one wishes to gain from one's categories is a great deal of information about the environment while conserving finite resources as much as possible," and to be cognitively efficient, categories must be both specific enough to reflect all essential information and general enough not t

The fact that not all examples need to conform to the prototype is one of the strengths of the prototype theory: better examples better resemble the categorical prototype but there is a continuum of better (Dopkins & Gleason, 1997, p.1). Cognitively, according to prototype theories, "people represent categories in terms of some central tendency computed over the category training instances and classify objects on the basis of how similar they are to the prototypes of the alternative categories. By contrast, according to exemplar models, people represent categories by storing the individual training instances themselves" without prototypes (Zaki et al. 2003, p.1160).
Thus, if contrast to prototype theories, so-called exemplar theory suggests that learning proceeds from specific examples, and if prototypes are formed, this is only much later on in the subject's cognitive development, and is not universally the case. "According to the exemplar theory, a category's mental representation encodes the exemplars that compose the category. To decide whether an entity is a member of a category, one compares it to the category's exemplars" (Dopkins & Gleason, 1997, p.1). These exemplars are empirically rather than deductively conceived. Exemplar theory can also account… READ MORE
