Working Memory Model - Landry and Bartlett

Question 1

Aim

Answer 1

To investigate if articulatory suppression will influence undergraduate psychology students’ abilities to remember 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, to conclude, this study supports the Working Memory Model as the results suggest that particularly suppression interferes with the rehearsal and manipulation of phonological information in the phonological loop. It provides evidence that the STM has a limited capacity. It also suggests that Short-term memory is more complex than originally theorised and requires articulatory processing.
