#12 u3aos2 - mutli-store model of memory (ch6a) Flashcards
explanatory power
1 mark
the ability of a theory/model to explain the matter of a subject effectively
memory
3 marks
an internal record of a prior experience or event
it is known as the encoding, storage, and retrieval
of information acquired through learning
encoding
2 marks
converting information into a usable form
so it can be processed by the brain
storage
1 mark
retaining encoded information over a period of time
retrieval
2 marks
accessing information that has been stored so that
we are consciously aware of it
multi-store model of learning
5 marks
represents memory as consisting of three distinguishable components / stores
that process information differently
but operating simultaneously and interact:
- sensory memory
- short term memory (STM)
- long-term memory (LTM)
role
1 mark
the function of a memory store
capacity
1 mark
the amount of information held within a memory store
duration
1 mark
the length of time information is held within a memory store
sensory information
1 mark
visual or auditory information
sensory memory
2 marks
a memory system
and the entry point for all new information
recieved by the senses into memory
characteristics of sensory memory
5 marks
- different categories: echoic and iconic
- capacity: unlimited
- duration: short period of time (couple of seconds)
- information is stored as an exact copy/replica of its original sensory form.
- information stored is not consciously aware of and acts like a filter to keep the relevant information.
what are the two sensory memory stores
2 mark
echoic memory store
iconic memory store
echoic memory store
2 mark
stores incoming auditory information
for 3 to 4 seconds
iconic memory store
2 marks
stores incoming visual information for 0.3 to 0.5 seconds
short-term memory (STM)
3 marks
a memory system
in which all the information we are consciously aware of
is stored for a relatively short period of time (unless renewed in some way
characteristics of STM
2 marks
- capacity: limited
- duration: limited
- known as working memory where information can be manipulated to perform everyday functions
- information in STM is no longer a replica but instead an encoding
working memory
1 mark
information is manipulated to perform everyday functions
characteristics of the capacity in STM
3 marks
- limited capacity with 5 to 9 pieces at a time
- however this can be increased by chunking information together
- when the STM is full, new information can only be added by getting rid of old information
what are two ways information can be forgotten in STM
2 marks
- displacement
- decay
displacement
1 mark
old info being pushed out by new info
decay
1 mark
memory fading due to the lack of use
characteristics of the duration in STM
- STM can last 30 seconds without interference
- recalling information declines after about 12 seconds
- almost all information dissapears around 18 seconds if not revived.
- maintainence rehearsal is used to increase the duration of STM
maintainence rehearsal
2 marks
the continual repitition of information
to increase the duration of STM
