aim

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

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

results

mean recall in control group: 76%

mean recall in experimental group: 45%

conclusion

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

support for WMM

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

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

• articulatory suppression overloads rehearsal capability
