memory encoding (Baddeley) Flashcards
who was the researcher for memory encoding?
Alan Baddeley
what was Alan Baddeley’s aim in his memory encoding study?
to investigate if there was a difference in the type of encoding used in STM and LTM
what were the IV’s in Baddeley’s memory encoding study?
time between learning words and being tested (immediately or after 20 mins)
the type of word list each group were assigned (acoustically similar/dissimilar of semantically similar/dissimilar)
what was the DV in Baddeley’s memory encoding study?
number of words recalled (immediately or 20 mins)
what was the CV in Baddeley’s memory encoding study?
the amount of words
the rate at which the words were read
what type of research method was Baddeley’s memory encoding study?
lab experiment
what experimental design was used?
independent groups
what were Baddeley’s results/findings in his memory encoding study?
‘B’ (acoustically dissimilar) was recalled better than ‘A’ (acoustically similar)
and
‘D’ (semantically dissimilar) was recalled better than ‘C’ (semantically similar)
what were the conclusions of Baddeley’s memory encoding study?
STM: encoded acoustically
LTM: encoded semantically
what was the supporting evidence ‘Point’ of Baddeley’s memory encoding study?
the study was well controlled
what was the supporting evidence ‘Evidence’ of Baddeley’s memory encoding study?
he controlled how many words were in each list and how many lists people listened to
what was the supporting evidence ‘Explanation’ of Baddeley’s memory encoding study?
as potential extraneous variables were controlled, we are more confident that only the IV that affected the DV
what was the supporting evidence ‘Link’ of Baddeley’s memory encoding study?
increases validity in Baddeley’s study into encoding and increases our confidence that the results show STM encodes acoustically and LTM encodes semantically
what is the opposing evidence ‘Point’ of Baddeley’s memory encoding study?
Baddeley may not have been testing long-term memory
what is the opposing evidence ‘Evidence’ of Baddeley’s memory encoding study?
for those in conditions ‘List C’ and ‘List D’, pp’s only waited 20 mins to recall their words
