PSYC 230 Lecture Notes - Lecture 9: Backpropagation, Multiple Choice, Interference Theory
Document Summary
Knowledge that enables us to recognize objects and events and to make inferences about their properties. Concepts: the mental representation of a class or individual, the meaning of objects, events, and abstract ideas. Category: all possible examples of a concept, ex: chair. Help to understand individual cases not previously encountered. Pointers to knowledge : categories provide a wealth of general information about an item, allow us to identify the special characteristics of a particular item. Not all members have the same feature: family resemblance (wittgenstein, 1953) Things in a category resemble one another in a number of ways. Ex: average faces from around the world. There would be lots of overlap for very similar objects. Statements about prototypical objects are verified easily. An apple is a fruit: takes less time. A pomegranate is a fruit: takes longer. The more prototypical, the faster they can respond to if it"s a fruit. Name all the fruits you can, apple would be first.
