Experimental designs-Repeated measure design

Question 1

A01

Outline Repeated measure design

Answer 1

• Participants cpmplete each of the experimental conditions
• P produce two sets of data, one from each condition
• Data then compared
• Produces related data

Question 2

A03

Strength of Repeated measure design

Answer 2

There are no group differences as the same P are used in each condition , meaning Participant variables do not effect measurement of IV

( even if variables between p present , dont matter as if its affecting one condition it will have affected the oether-counteracting it)

Question 3

A03

Limitation of Repeated measure design

Answer 3

• Order effects- problem as P take part in all conditions, by repeating 2 tasks could create boredom causing deterioation in performance on second task,
  However, participant performance may improve through the effects of practice with skill based tasks
• Demand characteristics-P more likely to work out aim of study when they experience all conditions of the experiment
• More time is needed to allow for P to take part in multiple conditions
