Document Summary
Memory: processes involved in retaining, retrieving, and using information about stimuli, images, events, ideas, and skills after the original information is no longer present. Active any time some past experience has an impact on how you think or behave now or in the future. As with attention, there are many different kinds of memory. Control processes: active processes supporting encoding that can be controlled by the person: maintenance rehearsal: minimal retention benefits, elaborative rehearsal: optimal retention strategy. The use of different control processes affect the representations that are encoded, retained, retrieved, etc. Iconic memory: brief sensory memory of the things that we see responsible for persistence of vision: estimates of duration on the order of milliseconds. Echoic memory: brief sensory memory of the things that we hear responsible for persistence of sound: estimates of duration range from 1-4 seconds. Paradigm to measure the capacity and duration of sensory memory (sperling, 1960): Array of letters flashed very quickly onscreen.
