To test recall of acoustic similarity and acoustic dissimilarity in STM
cognitive practical method:
used repeated measures
presented a list of 10words - first being acoustically dissimilar then acoustically similar sounding words
participants were asked to recall all 10 words in one minute after looking at them for 3 seconds
Cognitive practical FINDINGS:
Used measures of centraltendency and data showed that the mean is higher on list 2 which means it was easier to remember than list 1- by using willcoxon it was found that data was notsignificant
Strengths of cognitive practical:
Is a field experiment which creates a more naturalistic approach which can be applied to real life situations such as preparing for exams
provides evidence for Baddeley's study thus proving inter-rater reliability
Problems with the cognitive practical:
Participants used were college students which limits generalisability to target population
Used a opportunity sample which only regards who is available at the time
TO IMPROVE- use a variety of participants
how could cognitive practical be improved?
Change the methodology from repeated measures to independent groups as it would remove chance of order effects influencing the participants responses to recalling the lost of words in the second acoustically dissimilar condition, therefore producing valid findings into memory recall
