Atinkson And Shiffrin (1968) Multi-Store Model Of Memory Flashcards
What is the theory of the multi store model memory?
Atkinson and Shiffrin proposed that memory stores differ from each other in the way information is encoded, their capacity, duration and how information is retrieved
What is the sensory register and its role?
- immediate memory of sensory information
- if we pay attention to the sensory information it is transferred to our short memory store where we can process it further, if we do not pay attention to it, it decays
Sensory register (attention) —> STM (repetition)—> LTM
Short term memory-> capacity, duration, role of rehearsal
Duration: information we pay attention to gets transferred to STM where it can be stored for 15-30 seconds . If we rehearse this information we are able to retain it for much longer.
Capacity: 5-9 chunks of information
Long term memory -> capacity, duration
Capacity: Potentially limitless capacity
Duration: can hold information indefinitely
Two weaknesses of the Multi-store model of memory
1- overstating the role of rehearsal
2- unlikely that there is only one type of long term memory store, we possibly have several different types
strengths of the Multi-store model of memory
1- A lot of supporting evidence, cases of amnesia show how brain injury can damage long-term memories while short-term memories remain intact.
Role of attention in memory
The sensory register is the store that receives all of the sensory information around us and holds is very briefly, if we pay attention to this sensory information it is transferred to our short term memory
Role of rehearsal in memory
Repeating information over and over again helps to hold it in short term memory for longer, if the information is rehearsed long enough it is then transferred into the long term memory store
Structure and process of memory
The sensory register is the store that receives all of the sensory information from our environment and holds it briefly, when we do not pay attention to the information it quickly decays but if we pay attention to this information it is transferred to our short term memory store, when we rehearse this information it is transferred to our long term memory store.
Primacy and recency effect
The primacy effect occurs because words at the beginning of the list had been rehearsed and transferred into long term memory. The recency effect is the result of the words still being held in short term memory
