Landry and Bartling Flashcards
1
Q
What can this study be used for?
A
Working memory model
2
Q
Background
A
- Extension to MSMM
- Mainly focuses on explaining how STM works
- Proposed by Baddeley and Hitch in 1974
- Central executive (divides attention to different processes)
- Visual sketchpad (visual information)
- Episodic buffer ( links info from STM to LTM)
- Phonological loop (auditory processing)
3
Q
Year
A
2011
4
Q
Aim
A
To see if articulatory suppression would influence recall of 7 dissimilar letters
5
Q
Participants
A
34 undergraduate psychology students
6
Q
Experimental design
A
Independent measures design
7
Q
Procedure
A
- In control group, participants saw a list of letters for 5 seconds and then were asked to wait another 5 seconds and then recall words in correct order
- Experimental group had to repeatedly say ‘1’ and ‘2’ while recalling the list of words
- Each condition had 10 trials and average accuracy of recall was calculated
8
Q
Results
A
- Controll group recalled 76% of words in correct order
- Experimental group had sufficiency of 45%
9
Q
Explanation using WMM
A
- One of WMM’s stores is phonological loop.
- When it’s overwhelmed, working memory can’t function properly and the sufficiency is reduced
10
Q
Evaluation
A
+ Well controlled, IV/DV relationship clear
+ Supports WMM
- Low ecological validity due to the task provided
- Participant variability (some might have better memory than others)
