PSYC 255 QUIZ MODULE 5 | VERIFIED SOLUTION

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. How many levels are there to the independent variable in this study? • Question 2 2 out of 2 points When the effects of a prior treatment condition influences subsequent treatment conditions, a researcher is faced with this disadvantage to a within subject design. • Question 3 2 out of 2 points A within subject design will use _____________ participants than/as a between subjects design. • Question 4 2 out of 2 points In a within subjects design, all participants are exposed to all levels of the independent variable. A major concern to the participants going through all levels of the independent variable is becoming tired of participating in the study. What disadvantage is being described here? • Question 5 2 out of 2 points Janiszewski and Uy (2008) conducted an experiment in which they had 43 participants read 10 scenarios. All 43 participants each read all 10 scenarios. In this study, the researchers wanted to determine the impact of the scenario type on the anchoring and adjusting of participants. Anchoring and adjustment occurs when people use a starting point (anchor) as a basis to make judgments about a given scenario (adjustment). This is an example of what type of design? • Question 6 2 out of 2 points Dr. Herrman recommends that his students take the practice GRE before registering to take the real GRE. Dr. Herrman makes this recommendation because he knows that __________ can increase performance on subsequent experiences with the same tasks. • Question 7 2 out of 2 points Barlett et al. (2005) selected a between subjects design to study the influence of action figures on male body image. Which of the following reasons listed below is not a reason why Bartlett and colleagues would have selected the design? • Question 8 2 out of 2 points A _____________ design exposes participants to all levels or conditions of the independent variable. • Question 9 2 out of 2 points Carefully review the research matrix presented below. If this is a between subjects design, how many total participants will be used in the experiment? 10 participants 10 participants 10 participants Selected Answer: 30 • Question 10 2 out of 2 points Which of the following statements regarding a between subjects design is correct? • Question 11 2 out of 2 points Recall the research conducted by Bartlett et al. (2005) on the influence of action figures on male body image. If Barlett exposed participants to the three conditions in the same manner and found that scores on the third condition always decreased, he might be concerned about _________. • Question 12 2 out of 2 points Dr. Roberts with the Mayo Clinic conducted a study on individuals between the ages of 70–89 and found differences in men and women. In this example, gender of participant was the __________. • Question 13 2 out of 2 points In chapter 8, we mentioned a study that examined the relationship between where one lives (urban or rural) and when a specific form of cancer is diagnosed. For this example, the independent variable was where one lives. How many levels did the IV have? • Question 14 2 out of 2 points Jason is interested in the topic of perception. He has participants complete a task on a computer and measures reaction and number of errors. Jason is thinking of repeating this task after the participants have been exposed to the independent variable. Which of the following reasons bests describes why Jason might not want to have participants complete the task again? • Question 15 2 out of 2 points Janiszewski and Uy (2008) conducted an experiment in which they had 43 participants read 10 scenarios. In this study, the researchers wanted to determine the impact of the scenario type on the anchoring and adjusting of participants. Anchoring and adjustment occurs when people use a starting point (anchor) as a basis to make judgments about a given scenario (adjustment). How many levels are there for the independent variable in this study?
