Document Summary

Typicality effect = typical members of a category are judged more rapidly than atypical members. A network (an intergrated set of concepts representing a body of knowledge) A node (point or location in the network) Cognitive economy (each property is stored only once at the most general point in the hierarchy) Teachable language comprehender (quillian, 1966) goal = to create a program that could understand/process language. Testing snm semantic verification tasks (how long does it take to answer/verify questions) Depends on how far it is to get to the property on snm. New model spreading activation model (collins & loftus, 1975) Evidence for sam (meyer & schvaneveldt, 1971) Semantic priming = when an item in memory is accessed, the subsequent access of semantically related items is facilitated (i. e. faster) Lexical decision task = identify a series of letters as a word or non-word. Everything is stored in semantic memory as a list of features.
