Q

what were the findings of experiment 3

A

trial 1 and 2 - harder to learn list of acoustically similar words as Stm trying to hold the information
trial 3 and 4 the words are being transferred into ltm so the % recalled becomes similar
retest condition- words have been transferred into the ltm so no difference in recALL BETWEEN trial 4 and the retest
