Q

What is one strength, linked with different areas, about the WMM ?

A
  • different ares of the brain are activated depending on the task

Q

What is another strength, linking to support evidence, about the WMM ?

A
  • support evidence from duel task research
  • hitch and baddeley found performance decreased when participants had to do task that required the same slave systems.
  • we can multitask if they require the same slave system e.g. articulatory and phonological

Q

What is a weakness, about ecological validity, about the WMM ?

A
  • lacks ecological validity

Q

What are the STRENGTHS of the study of STM duration ?

- Brown; Peterson Peterson

A

PRACTICAL APPLICATIONS

HIGH CONTROL

  • lab study
  • variables controlled
  • reliable / valid

ADDS SUPPORT

39
Q

What is the WEAKNESS of the study of STM duration ?

- Brown; Peterson & Peterson

A

NO ECOLOGICAL VALIDITY

  • not realistic
  • hard to generalise
40
Q

What are the STRENGTHS of the study of LTM duration ?

HIGH CONTROL

  • lab study
  • reliable / valid

ADDS SUPPORT
- MSM

41
Q

What is the WEAKNESS of the study of coding ?

- Baddeley

A

may not have been testing LTM as he only asked the pps to recall after 20 mins

42
Q

What is the STRENGTH of the research for MSM ?

- Glanzer & Cunitz

A

INDICATES DIFFERENCE

  • stm and ltm
  • emperical support = more credible
43
Q
