evualtion - duration

Question 1

one limitation of peterson and petersons study

Answer 1

meaningless stimuli
we sometimes try to recall meaningless things so the study is not completely irrelevant
but recall of consonant syllables does not reflects meaningful everyday memory tasks
lacks external validity

Question 2

strength of bahrick et al study

Answer 2

hugh external validity
everyday meaningful memories were studied (people’s faces and names)
when lab studies were done with meaningless pictures to be remembered, recall rates were lower (e.g shepard 1976)
means his bahrick et al findings reflect a more real estimate of the duration of LTM
