Document Summary
Trace fades quickly ie trying to remember dot patterns on the screen. Other registers very poor ie smell, touch etc. Rapidly lost unless we actively do something with it. Very limited capacity: 7 +/- 2 items, and chunk helps. Decay: material gets old, fades away over time. Interference: new material pushes old materials out of the way. People learned a 48 word list, and asked to recall them after right away, some are asked later like 1 hr, 5 hr to 8 hr etc . If people are awake during the 8 hours, they forget most of it. If people sleep for 8 hours after remembering the list, then they can still recall 80% of the information. Acoustic coding: ie , a list of 3 word: cook, car, dish or book bar fish. Semantic coding (code by meaning): ie cook car dish (ie cook dish) and more interfered by: chef, auto, plate. How to get info from stm to ltm.
