Exam 7: Repeated Measures Designs

A psychologist wishes to have participants rate two different sets of inkblots (labeled A and B)for their "emotionality." The inkblots differ in their use of color.Ten inkblots in set A are created in shades of gray; ten inkblots in set B use shades of red,blue,and yellow.The psychologist hypothesizes that color will influence participants' ratings of emotionality.Each participant will rate all twenty inkblots. What potential confounding variable must be balanced in this research? Explain what balancing procedure would be best for this experiment. B. Ten random sequences of A and B inkblots would counterbalance practice effects.

Question 1

Correct Answer:

Verified

Practice effects need to be balanced in this repeated measures experiment.Participants should not rate the set of A inkblots followed by the set of B inkblots (or vice versa).Because this experiment uses a complete repeated measures design,ABBA counterbalancing or block randomization is appropriate.Block randomization is preferable when participants might anticipate the presentation of particular conditions; these anticipation effects could influence participants' responses of the emotionality of the inkblot.In block randomization each block would contain one inkblot from set A and one inkblot from set B.Ten random sequences of A and B inkblots would counterbalance practice effects.

A researcher designs an experiment with six conditions but each condition takes only a very short amount of time to administer.The researcher has the opportunity,therefore,to administer many trials of each condition in the experiment.Which of the following techniques is likely to be most effective for balancing practice effects?

Question 2

Correct Answer:

Verified

An incomplete repeated measures design experiment was done to test people's ability to solve problems that varied in difficulty at three levels (easy,moderate,and hard).The researcher used all possible orders to balance practice effects.Results indicated that performance on the hard problems was better when they were preceded by a moderate difficulty problem than when they were preceded by an easy problem.Which of the following is a possible explanation of this finding?
