Lesson 3: Multi-store model of memory Flashcards
Who was the multi-store model of memory developed by?
Aktinson and Shiffrin (1968)
What does the MSM attempt to explain
It attempts to explain how information flows from one memory store to another.
What are the three permanent structures in the memory system?
the sensory register (SR), short-term memory (STM) and long-term memory
What type of information enters the sensory register (SR)
ENVIRONMENTAL stimuli received through the SENSES
What’s the duration of the SR
250 milliseconds
Whats the capacity of the SR
UNLIMITED
as information is being received through all of the senses
How does information from the SR enter the STM
paying ATTENTION
Whats the CODING, DURATION,CAPACITY of STM
coding: acoustically
duration: 18-30 seconds
capacity: 7+/-2 items
Which type of rehearsal keeps information in the STM?
maintenance rehearsal
What is maintenance rehearsal?
repeatedly verbalising or thinking about the information
What happens if information is not rehearsed in the STM
it will be lost due to decay
What type of rehearsal transfers information to the LTM
Elaborative rehearsal
What is elaborative rehearsal?
making links to pre-existing information in memory
What is the CAPACITY, DURATION + CODING of LTM
capacity: unlimited
duration: unlimited
coding: semantically
What happens when information in LTM is needed
it is RETRIEVED by STM and recalled
