PSYC 255 Quiz 5 PRACTICE QUESTIONS AND ANSWERS Question 1  2 out of 2 points What kind of study uses a methodology in which participants are matched on a particular characteristic before being assigned to the different levels of the independent variable? Question 2  2 out of 2 points Participants experiencing the same order of presentation of the levels of the independent variable can lead to . . Question 3 Which of the following is a disadvantage to a between subjects design?  2 out of 2 points Question 4  2 out of 2 points Which of the following is not a disadvantage to a between subjects design? Question 5  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 6 A research matrix is . 2 out of 2 points Question 7 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 8 2 out of 2 points The degree of spread among data when surrounding the mean is known as . Question 9 2 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 10 2 out of 2 points 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? Question 11 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 12  2 out of 2 points 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? 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 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 15  2 out of 2 points In a , participants will be exposed to only one level of the independent variable. Question 17  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 18 Which of the following is an advantage to a between subjects design? 2 out of 2 points Question 20 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 21 2 out of 2 points Katie is conducting a within subjects design. Her independent variable has 2 levels that must occur 1 week apart. In the first session during the first week, Katie has 120 participants. However, a week later when the second session occurs, Katie only has 85 participants show up for the study. What disadvantage to within subject designs is Katie encountering? Question 22 2 out of 2 points To combat order effects that may occur with a within subjects design, many researchers will use . Question 23 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 24 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 25 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 26 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?
