Document Summary
Learning objectives: define the different types of memory and memory tasks. Short-term memory: a limited capacity store that holds information for a relatively brief period. Long-term memory: storage of memory after some elaborative processing has occurred, list the coding, limiting factors and processes associated with sensory memory, stm and wm. Sensory memory: coding: unprocessed sensory information, limiting factors, capacity: 9-12 items for iconic memory, duration: ~150ms for iconic and 4-5s for auditory and tactile, process: attention. Sperling was not convinced that we can only remember three or four items at a time thus conducted his own experiment. Showed participants array of letters (showed for seconds). When asked to remember as many letters as they can (whole report), people can only remember 3-4 items. Presented participants with an array of letter for less than a second and asked them to recall as many letter as they could from one row.
