4.1.2 Memory Flashcards
who made the multi store model ?
Atkinson and Shiffrin
when was the multi store model proposed ?
1968
key points of the multi store model
memories have 3 stores
and the information goes through a series of storage stages
what are the 3 stores of memories?
sensory register
short term memory
long term memory
what is meant by coding ?
the form in which the information is stored in
what is meant by capacity ?
how much can you store at once
what is meant by duration ?
for how long can you recall information until you start to forget it
what is an iconic memory ?
visual information from they eyes
what is meant by echoic memory ?
auditory input from ears
what is meant by a haptic memory ?
touch input from the body
what is a model of memory ?
a representation of memory
what does the sensory register do ?
takes info from one of the sense organs and holds it in the same form
- coding
Evaluation points for Baddeley 1966
- the study was a lab study so we can show causality (cause and effect) and it can be replicated to check the results
- may lack ecological activity
- Baddeley’s findings make cognitive sense
Evaluation points for Peterson and Peterson 1959
- flawed because different trigrams were used every time, which means some people may had easier letters to remember
- Marsh et al 1977 - if participants are not expecting to recall info, STM duration was only between 2 and 4 sec
Evaluation points for Bahrick et al 1975
- higher external validity, real life meaningful memories were studied
- when studies on the LTM have been conducted with meaningless pictures, recall was lower
- downside = confounding variables cannot be controlled because they might have looked at the pics over the years so memories might be rehearsed
