PS260 Chapter Notes - Chapter 9: Exemplar Theory, Prototype Theory, Connectionism
Document Summary
Understanding concepts: you need concepts to have knowledge and you need knowledge to function. Wittgenstein proposed that ordinary categories like dog or game or furniture work the same way. There may be no features that are shared by all dogs or all games, but even so, we can identify characteristic features for each category features that many category members have. And the more of these features an object has, the more likely you are to believe it is in the category. Eleanor rosch"s theory: prototype theory: perhaps the best way to identify a category is to specify the center of the category, rather than the boundaries. Just as we spoke earlier about the ideal family member, perhaps the concept of. Whenever you use your conceptual knowledge, your reasoning is done with reference to the prototype. Membership in a category depends on resemblance to the prototype and resemblance is a matter of degree.
