Q

A

infinite

Q

2 strengths of MSM

A
  • scoville: treat a patient called HM, removing different brain areas, patient could not code new LTM but STM was unaffected
  • murdock: pps recall long list of words, words at beginning (primacy effect) and end better than those at the end(recency effect) (serial position effect)
19
Q

2 weaknesses of MSM

A
  • oversimplified: different types of STM, several types of LTM
  • baddeley and hitch say MSM doesn’t explain multitasking: one STM means multi-tasking is impossible but people do it all the time e.g. listening to radio and driving
