Q

Rational and aim

A

Rational = replicating Baddeley (1966a) which found that acoustically similar condition was harder to recall than the acoustically dissimilar condition for the STM
Aim = to investigate whether acoustically dissimilar words will be recalled more successfully than acoustically similar words in the STM

Q

Procedure

A
  • repeated measures
  • list of 10 acoustically similar words were shown for 3 secs
  • participants had to recall them in the right order
  • process was repeated for acoustically dissimilar condition
  • mode median mean range and standard deviation was calculated

Q

Methodological strength

A

Standardised procedures due to the slideshow of 10 for 3 secs for all participants therefore replicable therefore reliable

Q

What inferential test did you use to analyse your data?

A
  • wilcoxon process
    1) test of difference for acoustically similar/disimlar words
    2) repeated measures so same group of pps took both conditions
    3) level of measurement so ordinal data used to rank participant scores of how many similar/dissimilar words were recalled

Q

Methodological weakness

A
  • 10 female only 5 male
  • estrocentric
  • not representative of the effect of acoustically encoding to STM to the wider population
  • not generalisable

Q

How to improve methodological weakness

A
  • get a larger sample with even gendered participants
  • e.g. 50 pps, 25 female and 25 male
  • to be more representative
