Memory: processes involved in the encoding, retaining, retrieval, and use of info about images, events, ideas, and skills after the original info is gone. Retaining: keeping info until you need it. Retrieving: getting info from stored place in order to use it. Duration: how long info can be held. Capacity: how much info can be held. Control processes system specific processes affecting duration and capacity. *sensory memory: retention of sensory info for a very brief time. *whole report procedure: briefly flash letters on screen and subjects report what they saw. *partial report procedure: letters are flashed then a tone is played right after indicating which row to report. Results: people report all or almost all letters in cued row. When there is delay between tone and report, less letters are reported. *iconic store: brief visual sensory store that fades after 1 second. Sperling also found that if subjects saw dark screen after seeing letters, they retained icon for 5 seconds.
