Question 2

Aim

Answer 2

Investigate if articulatory suppression would influence recall of written list of phonologically dissimilar letters in serial recall

Question 3

Sample

Answer 3

34 undergraduate psychology students

Question 4

Procedure

Answer 4

• Participants randomly allocated into two groups:
  Control group (no articulatory suppression)
  Experimental group (Performed the task with articulatory suppression)
• Each participant was tested individually
• Asked to recall 10 sets of 7 phonologically dissimilar letters
• These sets were shown to both groups one at a time, with a 5 second view time for each set, 5 second wait, and then writing down the set as best as they could remember on an answer sheet with seven blanks.

Question 5

What was the articulatory suppression task?

Answer 5

Repeatedly saying the numbers 1 and 2 at a rate of 2 numbers per second

Question 6

Results

Answer 6

Mean percent of accurate recall in the control group was 76%, much higher than the 45% mean in the experimental group with articulatory suppression.

Question 7

Research Method

Answer 7

True experiment

Question 8

Evaluation

Answer 8

Strengths:
- Well controlled study with high level of internal validity
Limitations:
- Artificial (Lacks ecological validity)
