Landry and Bartling Study (cognitive)

Question 1

Landry and Bartling Study (cognitive)

Aim

Answer 1

To reproduce the effect of articulatory suppression on serial recall of a written list of phonologically dissimilar letters and demonstrate the role of the phonological loop in the WMM.

Question 2

Landry and Bartling Study (cognitive)

Procedure

Answer 2

• 14 university-aged participants
• 2 groups: control and experimental
  
  • Experimental group experienced articulatory suppression (repeated numbers 1 and 2 while reading the letters) while learning the series of letters
• Each participants had 10 trials (randomized order)
• Letters chosen for the study were phonologically dissimilar (F K L M R X Q)

Question 3

Findings

Answer 3

• Experimental group scored lower than the control group
• Supports working model of memory
  
  • Articulatory suppression interferes with the phonological loop

Question 4

Landry and Bartling Study (cognitive)

Strengths

Answer 4

• reliable: easy to replicate

Question 5

Landry and Bartling Study (cognitive)

Limitations

Answer 5

• Not possible to know whether participants were engaging their phonological loop or visuo-spatial sketchpad to learn the letter sequence
  
  • Modification: Read letter sequence to participants rather than have them read it.
