Document Summary

Memory: getting information in, keeping it there, getting it back out when needed. Atkinson & shiffrin (1968) model of memory: sensory register short term store long term store. Iconic memory: george sperling, used a tachistoscope, typical paradigm. Array of letters and digits to ss on the t-scope for brief durations. Task = report what they remember from the display. Level of accuracy remained the same whether exposure was 5ms or 500 ms. Partial report: report only one row, signaled which row to be reported after presentation, average =3/4 items correct (76%, conclude: great deal of sensory info is available in iconic memory. Lasts about 250 or 300 ms: capacity. Only about 4 items can be reported, but actual capacity is longer. Letters that sound alike confused with each other: rarely structural confusions. Don"t confuse letters that look alike: rehearsal= verbal recitation, chunking.
