See attached. Must answer each question thoroughly.
Scenario A (10 points): A professor is interested in whether taking online quizzes over a chapter before discussing the chapter in class will improve students’ test performance. The professor is interested in examining the testing effect, the finding that taking a memory test not only assesses what one knows, but also enhances later retention. The professor hypothesizes that students who take chapter quizzes will score higher on the midterm exam than students who do not take chapter quizzes.
1. Design and describe an experiment that could test this hypothesis (4 points).
2. Identify the IV and DV (3 points).
3. Provide an operational definition of each variable (3 points).
Scenario B (10 points): Consider the following experiment. Each participant interacted for an hour with another person who was actually a research confederate (an actor working for the researcher). The confederate either presented herself as similar or dissimilar to the participant. After this interaction, both persons agreed to return 1 week later for another session with each other. When the real participants returned, they were falsely informed that the person they had met the week before had died. The researchers then compared how long the participant spent viewing a picture of the “deceased” depending on whether the person had presented as similar or dissimilar to them. The participant was never told that the reported death was untrue.
1. Write a hypothesis that is tested in this study (4 points).
2. Discuss the ethical issues raised in the experiment (3 points).
