PSY 255 QUESTIONS AND ANSWERS QUIZ 5

PSY 255 QUIZ 5 • Question 1 2 out of 2 points 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. What is the independent variable in this study? • 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 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 4 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 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 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 7 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 8 2 out of 2 points Participants experiencing the same order of presentation of the levels of the independent variable can lead to . • Question 9 2 out of 2 points William the researcher conducted a study on monitor size and reaction time. The research matrix is given below. 17 inch 19 inch 21 inch 25 participants 25 participants 25 participants If you wanted to give every participant in the study a piece of paper with the contact information of the researchers, how many pieces of paper will you need for this between subjects design? • Question 10 2 out of 2 points Conner is conducting a within subjects design with four levels to his independent variable. Conner has ¼ of the participants complete each level in ABCD order, a ¼ of participants in BCDA order, a ¼ of participants in CDAB order, and a ¼ of participants in DABC order. What is Conner using to limit order effects? • Question 11 2 out of 2 points occurs when the effects of a prior condition influence subsequent treatment conditions. • Question 12 2 out of 2 points Which of the following statements regarding a between subjects design is correct? • Question 13 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 14 2 out of 2 points occur when participants improve performance due to subsequent experiences on the same task. • Question 15 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? No Caffeine 8 Ounces 24 Ounces 10 participants 10 participants 10 participants • Question 16 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 17 2 out of 2 points To combat order effects that may occur with a within subjects design, many researchers will use . • Question 18 2 out of 2 points Which of the following is not a disadvantage to a between subjects design? • Question 19 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 20 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 21 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 22 2 out of 2 points 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 23 2 out of 2 points Suppose 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 24 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 25 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 26 2 out of 2 points During the late 1980s and the early 1990s the Pepsi Challenge was in full swing.

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 independent variable in this study? • Question 30 2 out of 2 points A research matrix is .
