Chapter 6 memory Flashcards
what is memory e,s,r
memory is an active process system that encodes, stores and recovers information when required
encoding
converting information into a usable form of storage
storage
retaining information overtime
retrieval
accessing previously stored information to use
atkinson-shiffrin model S _ STM _ LTM
incoming sensory information is held in sensory memory (exact)
attention: moves to short term memory (consicous)
encoding to long term memory
retrieval moves back to short term
sensory memory
duration 0.2-0.4 seconds
unlimited capacity
short term memory
18-30 seconds
5-9 capacity
long term memory
unlimited duration
unlimited capacity
-takes about 30 minutes to consolidate information
visual information stored in
iconic memory
auditory information stored in
echoic memory
george sperling
supported unlimited capacity of iconic memory through the use of a tachistoscope to flash visual stimulus for a brief period of time
echoic memory
duration 3-4 seconds
unlimited capacity
increase/decrease short term memory
increase = rehersal decrease = chunking
rehearsal
maintenance rehersal
elaborative rehersal
maintenance rehersal
simple repetition of information to help retain
elaborative rehersal
adding meaning to information/linking to information previously stored in ltm
chunking
grouping individuals items into small chunks or units to increase capacity of stm
long term memory types
procedural memory
declarative memory
procedural memory
knowing how
declarative memory 2 types
knowing that
semantic memory: academic facts
Episodic Memory:
autobiography events/ personal
semantic network theory
organisation of LTM is an interconnected grid of concepts
- inter related
- stronger the link, stronger the memory
- more links to memory, stronger it is
explict memories
-require conscious effot
semantic and episodic
-declaritive
implicit memories
- formed unconsiously
- procedural
- encoded in the cerebellum
