Document Summary
Memory- capacity to preserve and recover information; being able to store and recall ideas. Each stage involves several important processes: encoding- how memories form; taking in information for later recovery, storage- how memories kept over time; can be short, medium, or long timeframe, retrieval- how memories recovered and translated into behavior. Different systems for varying timeframes: sensory memory- last from milliseconds to seconds, short-term (stm) and working memory (wm) Last from seconds to minutes: long-term memory. Last months to years: large gap (cid:271)etwee(cid:374) (cid:272)ategories (cid:894)(cid:373)i(cid:374)utes to (cid:373)o(cid:374)ths(cid:895); i(cid:374) ge(cid:374)eral, we do(cid:374)"t k(cid:374)ow how memories go between short-term and long-term (large grey area being studied extensively) Sensory memory: memory is brief exact replica of stimulus; usually lasts for milliseconds to seconds, mind takes snapshot; picture fades away quickly. Picture exists in sensory memory (all get encoded and stored); problem is being able to retrieve- cannot do it before memory fades: classified by sensory modality.
