1
New cards

aim

to investigate if articulatory suppression would influence recall of a written list of phonologically dissimilar letters in serial recall

2
New cards

method

  • 10 lists of 7 letters: F, K, L, M, R, X, Q

  • Experimental group said ‘1,2‘ from the time the list was shown until they filled the answer sheet

  • control group saw list for five secons, waited five seconds, then wrote down

  • repeated ten times

  • scored for accuracy of recall

3
New cards

results

mean recall in control group: 76%

mean recall in experimental group: 45%

New cards

conclusion

articulatory suppression prevents rehearsal in the phonological loop because of overload, which supports the working memory

5
New cards

support for WMM

  • disruption of phonological loop through use of articulatory suppression results in less accurate worling memory

  • more difficult for participants in experimental conditions to memorise letter strings than participants in control group

  • articulatory suppression overloads rehearsal capability
