to investigate the influence of semantically and acoustically similar words on learning/recall of both the stm and the ltm.
baddeley - sample + procedure.
sample of Cambridge university students from applied psychology course. procedure involved independent groups - semantically or acoustically similar or dissimilar words given. given one word every 3 seconds. one minute to write word list. this was repeated 4 times.
baddeley - findings.
the semantically similar group struggled much more to maintain their word list from their ltm. semantically similar had a mean average of 58% recall while semantically dissimilar was 90%.
baddeley - conclusion.
semantic similar words are the most confusing to recall, which suggest that the ltm encodes semantically and that semantically similar words can impair learning sequences.
baddeley - evaluate for G.
not very as uni students taking psychology - risk of participant variables as they may be better performing than if art students or normal people did it. small sample and also lab which makes it un generalisable.
baddeley - evaluate using R.
very controlled and replicable, lab study which is a standardised procedure. making them repeat 4 times adds control.
baddeley - application value.
not very applicable or useful to society. gives knowledge on the ltm and may be used in some way to understand more. understand encoding better.
baddeley - evaluate for V.
lacks ecological and population validity. high internal control due to controls and being a lab study.
baddeley - evaluate for ethics.
consented and had right to withdraw, but study does not have any risks overall! no psychological harm can occur.
