Landry and Bartling Support for WMM

Question 1

Aim

Answer 1

Investigate if articulatory suppression would affect the recall of a list of letters which were phonologically dissimilar in a series of recalls

Question 2

Articulatory Suppression

Answer 2

Process of inhibiting memory performance while speaking while being presented with an item to remember
-Task= recite the numbers &2 per second

Question 3

Participants

Answer 3

34 Undergraduate students

Question 4

Method

Answer 4

Two Conditions

• Experimental group=participants were asked to recall a list of letter whilst administering the articualtory repression task
• Control Group=Memories letters of the list and no suppression task

Question 5

Procedure

Answer 5

Independent Sample Design=participants tested individually

• 7 letters with phonological differences
• Viewed a practice list
• Participants asked to review letters for 5 seconds and then 5 seconds after, recall letters chronologically
• Trial=10x

Question 6

Results

Answer 6

Percentage of accuracy for control group was greater than experimental group

• Mean percentage of control group=76%
• Mean percentage of Experimental group=45%

Question 7

Conclusions

Answer 7

Support Experimental hypothesis, which challenged the working memory
-Supported the WMM as articulatory suppression is suppressing rehearsal in the PL

Question 8

Strengths

Answer 8

-No Testing effects. participants did not affect the reliability of data by rehearsing and improving

Question 9

Limitations

Answer 9

No check on intelligence of participants

-No matched pairs, variability of participants in different groups may have influenced the data
