Working Memory Model - Landry and Bartling

Question 1

Aim

Answer 1

To investigate if articulatory suppression will influence the ability to recall a written list of phonological dissimilar letters in a serial recall.

Question 2

Method

Answer 2

The participants of this study consisted of 34 undergraduate psychology students.

In the experimental group, an articulatory suppression task was used where participants had to memorise and recall a list of letters while repeatedly saying the numbers 1 and 2.

In the control group, participants were also given a number of lists of letters, however, they did not engage in an articulatory suppression task

Question 3

Results

Answer 3

The results showed that the control group recalled on average 76% of the list, compared to the articulatory suppression condition with 45%

Question 4

Conclusion

Answer 4

Therefore, Landry and Bartling’s study supports the WMM, as articulatory suppression prevents rehearsal in the phonological loop because of overload. Therefore, participants with the articulatory suppression task had more difficulty memorising the letters than the control condition. This suggests that short-term memory is more complex than originally theorised and information may require articulatory processing.
