L33 Psych 100B Lecture 17: Memory Store and Retrieval
Document Summary
Working (short-term) memory: unrehearsed info quickly lost. Long-term memory: some info may be lost over time. Function: aid to perception, how to use sensory information. Experiment flashing 2 slides to distinguish letters. 250 milliseconds before someone won"t remember the pattern of dots they see. Could have large amounts of sensory information at once. Info quickly lost from sensory store unless passed on to different store. Function: mental workspace, hold info in consciousness in order to something with that info. Fbinbcnflcia = 12 letters, chunk into fbi nbc nfl cia = 4 items. If rehearse (repeat in head), info stays a little longer. Moving info into long-term memory; shallow -> deep processing = remembered poorly -> remembered better. Sometimes already in place, other times we have tendency to organize them ourselves. Info requiring deep processing are remembered better. Orthographic questions (ex: is the word in capital letters?) Memory best when retrieval situation matches encoding context.
