Landry and Bartling : Memory Model WMM (COG)

aim of Landry and Bartling 2011

To test the working memory model, specifically the phonological loop by investigating articulatory suppression affects memory.

sample of Landry and Bartling 2011

34 psychology students were split into 2 conditions: Condition 1: participants had to remember a list of 7 letters while repeating 1,2 outloud. Condition 2: participants just had to remember the list of 7 letters.

results of Landry and Bartling 2011

The 2nd group performed much worse at recalling the 7 letters with 45% accuracy compared to group 1 who had a 75% accuracy.

evaluation of Landry and Bartling 2011

Highly controlled experiment so there is high internal validity and a cause and effect relationship can be established. There is low ecological validity because this is an artificial task and may not be representative of how articulatory suppression manifests itself or its effect on memory in real life. A small sample of 34 psych students impacts generalizability.

connection to the working memory model Landry and Bartling 2011

Components of the WMM by Baddley and Hitch which argues that the phonological loop stores and rehearses auditory and verbal information. It explains how people can hold onto words they are trying to remember by rehearsing them. The result of Landry and Bartling shows that the phonological loop has a limited capacity as when the participants in the articulatory suppression task had to do 2 verbal and auditory tasks at the same time which both required the phonological loop and ultimately resulted in decreased performance due to the limits of the phonological loop, this is evidence support the working memory model
