Question 1

evaluation: peterson and peterson
criticism- artificial stimuli (3)

Answer 1

-meaningless stimuli (trigrams) were criticised
-lacks external validity as it doesnt reflect everyday memory activities–>cant be generalised
-lab experiment lacks ecological validity

Answer 2

study is still relevant when recalling numbers in STM

Question 3

evaluation: jacobs
criticism- lack of control over confounding variables (2)

evaluation: baddeley
criticism- artificial stimuli (2)

Answer 5

-word lists had no personal meaning–>lacks mundane realism as its unreflective of the real world
