multistore model of memory

Question 1

Multi store model of memory intro

Answer 1

• Atkinson and Shiffrin
• structural model
• suggests memory consists of 3 stores, all linked by processing
• differ in terms of coding, capacity and duration

Question 2

Sensory register

Answer 2

• information first comes in through senses
  coding - different sensory stores for unprocessed info
• limited duration
• very large capacity

Question 3

short term memory

Answer 3

• mainly acoustic coding
• 18-30s duration
• capacity 7+/-2
• can be increased by chunking

Question 4

long term memory

Answer 4

coding - mainly semantic
duration - up to a lifetime
- unlimited capacity

Question 5

information pathway

Answer 5

• info passed linear way
  1. external stimuli registered in SR
  2. if given enough attention, info to STM
  3. if rehearsed enough, info to LTM
• info can be lost from STM by decay and displacement
• info can be lost from LTM by decay and interference

Question 6

+

Answer 6

• is testable, able to distinguish memory stores
• KF case study
• brain injury from motorcycle accident, STM affected but LTM still in tact
• supports idea of separate stores

Question 7

—-con

Answer 7

• more plausible theories e.g. WMM (Tulving)
• explains LTM can be split into episodic, procedural and semantic memory, where MSM sees LTM as unitary
