Document Summary
Cues: one memory can act as a cue to trigger another memory. A basic memory task involves 2 phases: during the encoding phase, a subject learns a list of items, words or pictures, during the retrieval phase, subjects are tested for their memory of the items presented. Hermann ebbinghaus: constructed the forgetting curve. Which describes the rapidly decreasing rate of recall over time. Memory recall is highest immediately after learning and decreases over time. Most of the forgetting occurs early on, with the rate of forgetting slowing down over time. George miller: short term capacity is 7 plus or minus 2 items, if rehearsal stops short term fades. Chunking: george miller, info can be re-organized into chunks of meaningful pockets, which expands the capacity for short term, letter groupings pack even more info. Serial position curve: memory performance is best for items presented earlier or later and worst for items presented in the middle, primacy.
