Document Summary

Forgetting: how does information get lost from the store? (decay) Representation: what is the format of information in the store. George miller & herb simon: miller"s (cid:523)19(cid:888)(cid:887)(cid:524) analysis of short-term memory capacity (7+/- 2 chunks) Chunk: anything in the working memory, which has a unitary representation in long-term memory. Recoding: packing more information into each chunk, given that the number of chunks is limited. Mnemonic: (cid:498)shopping list: walk through the house to remember(cid:499) a technique for improving memory. Interference: poor remembering caused by interference by the counting task. Retroactive interference (ri): newer material interferes backward in time with your recollection of older items. Proactive interference (pi): when older material interferes forward in time with your recollection of the current stimulus. Saul sternberg: developed ways to measure working memory retrieval using recognition, not recall; used response time because accuracy would be perfect.
