M2. Multi-Store Memory Model Flashcards

1
Q

Multi-Store Model (MSM)

A
  • represents storage, transfer, and receipt of information between stores (and process of forgetting)
  • Sensory register, short-term memory, long-term memory

Q

Sensory register

A
  • contains 1 sub store for 5 sense (e.g. echoic store for auditory info)
  • HUGE capacity; < 0.5 second duration
  • information only passes from SR to STM if we PAY ATTENTION to it

Q

Short Term Memory (STM)

A
  • acoustically coded (Baddley)
  • 5 - 9 items (7+/- 2) (Miller)
  • duration: 18-30 seconds (Petersen)

Q

Maintenance Rehearsal

A
  • repeat new information to ourselves (attention), allowing it to be kept in the STM
  • prolonged MR allows info to pass into LTM
  • a lack of MR causes ‘forgetting’

Q

LTM

A
  • semantically encoded
  • capacity: unlimited
  • duration: 46+ years (Bahrick et al)
  • ‘retrieval’ occurs in order to remember info; information passed back into STM; and remains in ‘maintenance loop’ order to be remembered

Q
  • Eval: Oversimplification: Different LTM Types
A
  • Tulving et al.
  • LTM NOT a single store
  • procedural memory retrieved unconsciously
  • semantic received consciously

Q
  • Eval: Maintenance Rehearsal
A
  • MSM suggests that amount of maintenance rehearsal determines how much information is transferred into LTM (directly proportional)
  • Craik and Watkins: TYPE of Rehersal more important: elaborative rehearsal (linking knowledge) is more efficient than prolonged rehearsal

Q
  • Eval: STM as a single store
A
  • Patient KF had poor recall for auditory stimuli, but increasingly accurate recall for visual stimuli
  • KF also able to differentiate and recall between both verbal and non-verbal sounds
  • suggests multiple STM stores
