Atkinson and Shiffrin (1971) proposed that memory is made up of three information stores. Sensory memory can hold information just long enough (a fraction of a second) for a small portion of it to be selected for longer storage. Short-term memory has a limited capacity, and unless aided by rehearsal, its storage duration is brief. Long-term memory can store an apparently unlimited amount of information for indeterminate periods. Memory 34 In last Class Memory (basic processes) Storage in Information processing theory Sensory M approximately second Afterimage George Sperling (1960) STM LTM Memory 36 Limited capacity store that can maintain unrehearsed information for up to about 20 s Limited capacity magical number 7 plus or minus 2 (Miller, 1956) Chunking grouping familiar stimuli for storage as a single unit Limited duration about 20 seconds without rehearsal Rehearsal the process of repetitively verbalizing or thinking about the information Short Term Memory (STM) Memory 37 Figure 7.9 Peterson and Petersons (1959) study of short-term memory. After a warning light was flashed, the subjects were given three consonants and numbers to remember. The researchers prevented rehearsal by giving the subjects a three-digit number at the same time and telling them to count backward by three from that number until given the signal to recall the letters. By varying the amount of time between stimulus presentation and recall, Peterson and Peterson were able to measure how quickly information is lost from short-term memory.
