type of declarative memory; memory of specific events; more fragile than semantic memory

first stage in declarative memory process; incoming sensory information; capacity is very limited, decays in less than a second if not attended
short-term memory (STM)
second stage in declarative memory process; attended sensory memory; capacity is limited, decays in 20-30 seconds if not attended
chunking
grouping items into meaningful sequences to better memorize in STM
long-term memory (LTM)
third stage in declarative memory process; capacity is unlimited, lasts for a life time
encoding
turning memory into a neural code
state dependent learning
better at remembering thins when your body is in the same state as it was during encoding
storage
retaining/storing the physical input from your encoding stage
reconstructive memory
concept that memory is recomposed to fill in gaps of likely events
