PSYC 220 Lecture Notes - Lecture 19: Semantic Memory, Lexical Decision Task, Temporal Lobe
Document Summary
Study question: describe the tlc hierarchical, the feature comparison & spreading activation models of semantic memory. Jan 26th/16: collins & quillan(cid:495)s tlc (teachable language comprehender) (fig. 9. 12) (the model works through spreading activation- when you activate a part of the model it spreads to another part predicted that it takes longer to confirm a canary is an animal than a canary is a bird) Pros: precursor for other models, accounts for empirical data, cognitive economy- the tendency for cognitive processes to minimize processing effort & resources. Cons: strictly hierarchical (faster to confirm a pig is an animal than mammal, even though should be the opposite, only works for (cid:498)true(cid:499) propositions, cannot account for typicality or category size. Smith et al. (cid:495)s feature comparison model effects: the meaning is contained in 2 sets of semantic features, characteristic features- not necessary to the meaning, describe the concept & many members.
