  2. Tamir et al. (2008) conducted a study to see what impact music has on participants playing computer games.  The researchers had participants play computer games while listening to angry, exciting, and neutral music.  The researchers then measured the participant’s performance while listening to each type of music.  This is an example of what type of design?
  3. Carefully review the research matrix presented below.  If this is a within subjects design, how many total participants will be used in the experiment?

  6. We discussed a study known as the Stroop effect.  Stroop developed 3 types of stimuli for his study.  Each type of stimuli presented a different task that participants had to complete. Stroop then measured the amount of time it took the participants to complete each task. What is the dependent
    variable in this study?

  11. During the late 1980s and the early 1990s the Pepsi Challenge was in full swing.  During the challenge, participants were asked to taste cola from both Coke and Pepsi.  Once they had tasted both drinks, the participants were asked to report which was better tasting.  The results indicated that participants found Pepsi products to be better tasting.  This is an example of what type of research design?
  12. Darley and Batson conducted a study in which the independent variable was the degree to which the participants were instructed to hurry to the other building (high-hurry, intermediate-hurry, low-hurry) and the dependent variable was the amount of help offered to a “victim” placed by the researchers between the two buildings.  This was a between subjects design.  Therefore, how many groups of participants were needed?
