exemplar view
what does the exemplar approach account for / explain: what is the exemplar approach good for?
- explains typicality effect - easily takes into account atypical cases - easily deals w variable categories (categories w wide range of category members) - good for small categories as well (lke U.S. presidents)
combining prototype and exemplar approach introduces idea of what..
"core" >and still the idea of the prototype (characteristics typical of examples )
contrast exemplar approach and prototypical approach:
-representation is not abstract like prototypical , instead we have descriptions of specific examples
similarities between exemplar approach and prototypical approach:
-what we are representing isn't a definition
exemplars for concept of fruit
apple, lemon, banana
prototype what categories does prototype work best for?
characteristics typical of examples -works best for larger categories
what is a "core" ? what categories does it work best for?
defining features that item must have to be apart of category - works best for small categories
which of the 3 approaches has evidence?
evidence for all 3 approaches
the more similarity there is between a potential category member and the exemplar..
faster categorization
how do atypical members of a concept/category do with the exemplar view? -is pumpkin, cucumber, or tomato a fruit?
more difficult to determine atypical members
categorize by comparing...
new item to stored examples/exemplar in memory
exemplar view
uses multiple examples (also known as exemplars) to convey a concept / determine category membership
