Document Summary

Sensory memory (quick copy of sensory data we have just received) capacity- large. Accurately but briefly registers sensory or sound information before it fades or moves onto short-term memory. Includes 2 subsystem for: iconic- fast-decaying store of visual information (1/2 sec) and echoic- a fast-decaying store of auditory information (2-4 sec) Short-term memory (stm): a place where information is kept for a few seconds but less than a minute (up to 30 seconds) Rehearsal: process of keeping information in short-term memory by mentally repeating it. Capacity of stm: george miller believed the capacity of stm was 7 plus or minus 2. Chunking: allows more information to be managed in stm by combining small pieces of information into larger cluster or chunks that are more easily held in short-term memory. Long-term memory (ltm): hold all info we previously gathered, available for retrieval and use in new situation or task. Information acquired during an experience that guides present thought and action.
