Memory Flashcards
Name the 3 stores of the multi store model
Sensory
Short Term
Long Term
What 3 components does the sensory store break down into?
Iconic (Sight)
Echoic (Sound)
Haptic (Touch)
What is the duration of the Sensory Store?
0.5s
How is the Sensory Store encoded?
Info is processed from the senses
What is the capacity of the sensory store?
Unlimited
How is information transferred from the sensory store to the short term store?
By paying attention to it
What is the duration of the short term store?
18-30s
What is the encoding of the Short Term Store?
Maintenance Rehearsal
What is the capacity of the Short Term Store?
5-9 pieces of information
How is information transferred from the Short Term store to the Long Term Store?
Through elaborative rehearsal
How is information transferred from the Long Term Store to the Short Term Store?
Through retrieval
How is the Long term store encoded?
Semantically
(Remembered by meaning)
What is the capacity of the Long Term Store?
Unlimited
What part of the brain contains long term information?
Hippocampus
How can the multi Store Model be described?
Sequential and Linear
What study flashed images of letter O twice and found at 0.5 seconds, participants reported that they only saw one flash.
Walsh and Thompson
Outline the Findings of Walsh and Thompson (1978)
Duration of sensory store =0.5s
Decreases with age
What study investigated the capacity of the sensory store?
Sperling (1960)
Participants describing seeing more letters from a grid of 12 than they could report describes which study? How does this support Multi Store Model?
Sperling (1960)
Sensory store took in all the information however only some of it was paid attention to and transferred into short term memory.
What experiment found a 80% recall of nonsense trigrams after a 3 second interference task and 10% after 18 Seconds? What does this suggest?
Peterson & Peterson (1970)
That duration of STM is limited and that longer delay led to less recall as there was no chance for maintenance rehearsal.
Which experiment found that on immediate recall, words that sounded similar were the hardest? What does this suggest?
Baddeley (1966)
STm is learnt acoustically, hence trouble on words sounding similar.
Which experiment (1887) found that the in immediate recall, 9.3 numbers could be recalled in order, letters 7.3? What does this suggest?
Jacobs (1887)
Capacity of STM = (2-)7(+2)
Which experiment found that Ex US high schoolers could identify former classmates from 50 photos. 90% after 14 years and 60% after 47 Years? What does this suggest?
Bahrick et al (1975)
LTM can last a lifetime
LTM accuracy decreases with age
Which experiment found after a delay of 20 minutes, words with similar meanings were hardest to remember. What does this suggest?
Baddeley (1966)
LTM is semantically encoded, relies on meaning to understand.
Name 3 strength of the multi store model.
Lab research to support
Naturalistic Research to support
Practical application
Name an example of naturalistic supporting research of MSM
HM
Temporal lobes removed, leaving him with intact STM however no LTM. Suggests separate parts of brain control different parts of memory.
Name 2 Weaknesses of the Multi Store Model
Alternative theories that explain features more effectively.
Case study research that disputes validity of the theory (KF)
