What year was Landry and Bartling?
2011
What was the aim of Landry and Bartling?
To investigate whether articulatory suppression affects the recall of phonologically dissimilar letters in a serial recall task, as predicted by the Working Memory Model.
Landry: What was the experimental design?
Independent samples
Landry: Who were the participants?
34 psychology students
Landry - procedure
- Each participant viewed 10 lists of 7 phonologically dissimilar letters (e.g., F, K, L, M, R, X, Q).
- Control group: Viewed the list for 5 seconds, waited 5 seconds, then recalled the letters in order.
- Experimental group: Repeated “1” and “2” during the whole task (articulatory suppression).
Landry: results
Suppressed group had much lower scores. Statistically significant.
Landry: conclusion
Supported WMM –> articulatory suppression is preventing rehearsal in the phonological loop because of overload.
What are two strengths of Landry and Bartling’s study?
- It is well-controlled therefore has high internal validity. A cause-effect relationship can be established.
- It is easily replicable so the findings are reliable.
Landry: Is this study artificial or not?
Yes it is -> therefore it has low ecological validity?
Landry: Does this study support the Working memory model?
Yes
What was the research method that Warrington and Shalice (1970) used?
Case study
What was the aim of Warrington and Shalice?
To investigate the relationship between short-term memory and long-term memory when STM is impaired.
What patient did Warrington and Shalice test on in 1970?
KF
Why did KF suffer brain damage?
Motorcycle accident
What was KF’s special case that made him different from HM?
He lost his short term memory (just like HM), but he was able to learn (moving info from STM to LTM).
What did the researchers find out about KF?
They realised that he quickly forgot information that was told to him orally, but he remember visual information.
W & Sh: What implications did this have?
Since he lost his ability to remember verbal information (phonological loop), but remembered things visually (visuospatial sketchpad). This implies that there are two separate stores for verbal and oral information, supporting the WMM.
