Describe McGeoch and McDonalds study (procedure)
Pps learn list of 10 words until they remembered
Learned new list
Six groups of pps
Recall original list

Evaluation - evidence from lab studies
Consistent results, thousands of lab experiments
Valid explanation

May not apply to everyday life
Evaluation - real life studies
Baddeley and Hitch
Wanted to know if interference or passage of time was more important
Asked rugby players to name teams they’d played
Accurate recall did not depend on how long ago but number of games in the meantime
Evaluation - time between learning
Short times between due to practical reasons
Not reflective of real life
Longer the time between, less likely to be interference
Evaluation - interference effects may be overcome using cues
Tulving and Psotka Gave pps five lists of 24 words Six categories within lists Recall 70% at first but fell When given the names of categories recall rose to 70% again
