Document Summary
These are all methods used to illustrate typicality effects. In any natural category, there are members of that category that are regarded as. Typical members: some are more typical than others, ex. robin vs ostrich. Study phase: learn to categorize 4 distortions of each of 4 prototypes. Test phase: categorize, old distortions, prototypes (not seen at study, new distortions, key variable, retention interval. Preservation of specific experiences with members of a category could produce typicality effects without prototype abstraction. One view holds that category-level knowledge is acquired in the form of information about prototypes or information about the statistical properties of training items: this knowledge is represented separately from knowledge about training items themselves. Category level knowledge has no special status but emerges naturally from item memory. A novel item would be endorsed as belonging to a particular category as a function of the similarity between the new item and the exemplars of that category already stored in memory.
