second stage, maintenance of info over time to process it.
maintenance rehearsal

memory
process by which info is encoded, stored, retrieved
sensory memory
holds impressions briefly so series of perceptions are psych. continuous.

Ebbinghaus
developed nonsense syllables to measure function of memory
forgetting curve
rapid drop of number of retrievals over time, nonsense syllables precipitate, but you never forget everything
nonsense syllables
meaningless set of consonants used to study memory
recognition
identify objects or events encountered before
recall
retrieval or reconstruction of learned material
paired associates
nonsense sullables presented in pairs that measure recal
relearning
measures retention-- when material is relearned quickly than it was initially
interference theory
the view that we may forget stored material because of other learning interferes with it
retroactive interference
new stuff effects the ability to remember old stuff
proactive interference
old stuff effects ability to remember the enw stuff
