Memory

Question 1

Strengths of the MMM

Answer 1

• influential model, produces a lot of research
• lots of research to support the elements of model
• brain scans support idea of seep rate stores
• case studies support separate stores

Question 2

Weaknesses of MMM

Answer 2

• STM is not a unitary store
• No linear flow
• information can flow backwards
• over reliance on rehearsal

Question 3

Case studies to support MMM

Answer 3

• case of k.f
• case of h.m
• case of Clive wearing

Question 9

Case study to support duration of LTM

Answer 9

Bahrick et al 1975

Question 10

Case study to support the encoding of LTM

Answer 10

Baddeley 1966

Question 11

Outline the Working Model of Memory

Answer 11

1) Central Executive
- the boss
- directs the information for further processing
- limited capacity and is modality free
2) Episodic Buffer
- integrates both storages of information
- limited capacity
3) Visuo-Spatial Scratchpad ( inner eye)
- processes visual and spatial information dealing with movement and action as well as still images
4) Phonological Loop ( inner ear)
Two parts: articulatory loop and phonological store
-phonological store: stores acoustically coded information with limited capacity
- articulatory loop: deals with speech production as it acts as a verbal rehearsal loop, allows subvocal rehearsal of information stores in phonological store

Question 12

Strengths of WMM

Answer 12

• accounts for our ability to store information
• linear flow
• dual task study provides evidence of subcomponents

Question 13

Weaknesses of WMM

Answer 13

• Insufficient information about central executive
• only focuses on STM
• not comprehensive

Question 14

Case studies which provide evidence for WMM

Answer 14

• Baddeley et al 1973

- Baddeley + Hitch 1974

Question 15

Outline the multi-store model of memory

Answer 15

1) External stimuli: entered via 5 senses
2) Sensory Memory: information can be lost through decay and it has to be attended to for to pass through to the Short term Memory
3) Short Term Memory: limited capacity and duration. Capacity= 7+/-2. Duration= 18-30secs.
- information can be lost through decay and displacement
- for it to pass through to LTM it has to be maintenance rehearsed
4) Long Term Memory: unlimited capacity and duration.
- information lost by decay and interference
