Document Summary
Three-memory model - assumptions most researchers hold about the structure of memory and the relationships between its features (p. 242) The three memory stages are not viewed as anatomical structures in the brain, but rather as functionally distinct types of memory. Model classifies each memory store according to span (i. e. , how much information it can hold) and duration (i. e. , how long it can hold that information) (p. 242) 242-243) stores a lot of information but for very brief periods due to constant updating. Briefly holds sensory information (sights, sounds etc) after the stimulation is over. Rapidly and continuously being refreshed by new sensory information. Film looks continuous because sensory memory holds each image long enough to connect to the next. Persistence of vision iconic memory: visual sensorymemory echoic memory: auditory sensory memory. Sperling"s classic 1960 partial report task looked at span and duration for iconic memory. Whole report condition- average 4. 5 of 12 letters.
