72 men and women

Question 5

Answer 5

• split into 4 groups
• shown 10 words for 3 seconds

• recall words in order
• after 15 min break unexpected recall

Question 6

Answer 6

acoustically similar - confusing at 1st but then caught up with control, no forgetting

semantically similar- experimental group lags behind control, little forgetting but scores are lower

Answer 7

LTM encoded semantically, similar gets confused in LTM
STM encodes acoustically, similar gets confused in STM

Question 8

what are the strengths of baddeley

Answer 8

+ 72 ppts means anomalies will be averaged out
+ high reliability as conducted in controlled lab experiment using standardised procedures
+ if LTM encoded semantically, revise using mind maps, apply to students
+ high internal validity, cause and effect conclusions due to controlled nature, interference task

Question 9

what are the weaknesses of baddeley

Answer 9

• no ecological validity, recalling a list of words is unrealistic and artificial
