PSYCH 255 quiz 5 PRACTICE EXAM QUESTIONS AND ANSWERS SOLUTION Question 1  2 out of 2 points You want to replicate Barlett et al.’s research on action figures and negative body image in young adult males. Your independent variable has three levels: no action figures, highly muscular figures, and moderately muscular figures. You want to conduct a between subjects design. How many total participants will you need if you want 10 participants in each level of the IV? Question 2  2 out of 2 points 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. What is the dependent variable in this study? Question 3  2 out of 2 points occur when participants improve performance due to subsequent experiences on the same task. Question 4  2 out of 2 points Stacy has been working hard to look at the effects of homework difficulty on student desire to finish the work. She has decided to make sure that each group is equivalent on enthusiasm for school by measuring overall levels. Stacy then pairs up the participants based on their enthusiasm before placing them into the groups in her study. Stacy is conducting a design. Question 5  2 out of 2 points Which of the following statements regarding a within subjects design is correct? Question 6  2 out of 2 points In chapter 7, we used a between subjects design to see if caffeine influenced levels of alertness. We had three groups of participants: participants who received 8 ounces of a caffeinated beverage, participants who received 24 ounces of a caffeinated beverage, and participants who received no caffeine. If this was a between subjects design with 30 total participants, how many participants would be in each condition? Question 7 2 out of 2 points Carefully review the research matrix presented below. If this is a within subjects design, how many total participants will be used in the experiment? Immaculate Appearance Neat Appearance Sloppy Appearance 15 participants 15 participants 15 participants Question 8 Tamir et al. (2008) conducted a study to see what impact music has on 2 out of 2 points 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 9 2 out of 2 points Which of the following statements regarding a between subjects design is correct? Question 10 Tamir et al. (2008) conducted a study to see what impact music has on 2 out of 2 points 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? Question 11  2 out of 2 points Carefully review the research matrix presented below. If this is a within subjects design, how many total participants will be used in the experiment? No Caffeine 8 Ounces 24 Ounces 10 participants 10 participants 10 participants Question 12 When the effects of a prior treatment condition influences subsequent 2 out of 2 points treatment conditions, a researcher is faced with this disadvantage to a within subject design. Question 13 2 out of 2 points occurs when the effects of a prior condition influence subsequent treatment conditions. Question 14 0 out of 2 points While conducting her within subjects design, Geraldine notices that participants are failing to fully complete the last level of the independent variable. Specifically, subjects are leaving questions blank and do not appear to be placing as much effort into the study as they were in the first level of the independent variable. Geraldine is seeing what disadvantage to using a within subjects design? Question 15 Carefully review the research matrix presented below. If this is a within subjects design, how many total participants will be used in the experiment? Rock Music Group Rap Music Group Hip-Hop Music Group 30 participants 30 participants 30 participants Question 16 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? Question 17 2 out of 2 points Betsy is conducting a study on school psychologists. She is thinking of having school psychologists complete four experimental conditions each lasting one hour. A colleague suggests to Betsy that she modify the design so that different groups of school psychologists are used and Betsy will not have to worry about . Question 18 2 out of 2 points You want to replicate Barlett et al.’s research on amount of blood in a video game and measures of aggression. Your independent variable has 4 levels: maximum blood, medium blood, low blood, and no blood. You want to conduct a between subjects design. How many total participants will you need if you want 10 participants in each level of the IV? Question 19 2 out of 2 points In a , participants will be exposed to only one level of the independent variable. Question 20  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 21 Which of the following is an advantage to a between subjects design?  2 out of 2 points Question 22  2 out of 2 points Which of the following is not a disadvantage to a between subjects design? Question 23  2 out of 2 points Which disadvantage to within subjects designs involves a participant dropping out of a study or not returning to complete additional parts to a study? Question 24  2 out of 2 points 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. What is the independent variable in this study? Question 25 The degree of spread among data surrounding the mean is known as .  2 out of 2 points Question 26  2 out of 2 points A participant dropping out of a study or not returning to complete additional parts to a study is known as . Question 27  2 out of 2 points The degree of spread among data when surrounding the mean is known as . Question 28  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 29  2 out of 2 points April has 4 levels to her independent variable. She has participants in her study complete part A, followed by B, C, and then D. When she analyzes her data, she notices that level D is always different from the rest of the levels. April is most likely encountering what effect? Question 30  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 . .
