Document Summary
Acquisition, storage and retrieval: acquisition: getting new information into memory. What we do during acquisition affects storage & retrieval. Acquisition also depends on what is stored in memory. The route into memory: information-processing model: information passes through a series of stages; processing is serial; each stage provides the output to the next, early memory model referred to as the modal model (atkinson & schiffrin, 1968; waugh & norman, 1965: two main memory components: short-term memory (stm) and long-term memory (ltm) Third component sensory memory: modal model of memory: 3 rows of 4 letters briefly flash on screen (cid:0) r eport the letters you see. Whole report condition: report letters from whole 12-item display. Duration of retention interval did not matter. Partial report condition: report letters from cued row: display (cid:0) c ue. Average recall = 75% (3 letters out of 4) Duration of retention interval did matter: recall declined over time, 500 ms delay: partial report = whole report.
