Document Summary
The atkinson-shiffrin model: richard atkinson and richard shiffrin. Sensory memory: a memory store that accurately holds perceptual information for a very brief amount of time. Short-term memory (stm): a memory store with limited capacity and duration (less than a minute): chunking: organizing smaller units of information into larger, more meaningful units. Long-term memory (ltm): a memory store that holds information for extended periods of time, if not permanently. Stores: stores retain information in the memory without using it for any specific purpose. Control purposes: control purposes shift information from one memory store to another (represented by arrows in the model). Retrieval can reverse this, and bring information from the ltm back to the stm. Serial position effect: most people will recall the first few items from a list and the last few items, but only an item or two from the middle.
