STEP 3: 1. What was the research question that guided the work by Drews, et al.? What was their hypothesis (specific prediction)? The research question that guided the work was, what are the cognitive effects of talking a to passenger vs talking on the phone? Their Hypothesis was that having a conversation on the phone impairs your ability to concentrate more so than talking to a passenger. 2. The Independent Variables (IV) is/are: Talking to the passenger’s vs on the phone 3. The Dependent Variable (DV) is/are: The driver’s ability to drive 4. Were the participants randomly assigned to conditions? What is the purpose of random assignment? 5. Yes, the participants were randomly assigned as passengers or drivers. So the results could be more accurate. 6. What kind of research design did this study use, i.e., descriptive, correlational, or experimental? Explain your answer. I would say experimental because they used two variables to see the effects of a task.
