PSYCH 255 quiz 5 COMPLETE QUESTIONS AND ANSWERS SOLUTION UPDATED 2021 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 dependent variable in this study? Question 2 Which of the following statements regarding a between subjects design is correct? Question 3  2 out of 2 points 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 4 Which of the following is not a disadvantage to a between subjects design?  0 out of 2 points Question 5  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. This is an example of what type of research design? Question 6 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 7 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 8 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 9 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 Selected Answer: 10 Question 10 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 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. What is the independent variable in this study? Question 12 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 independent variable in this study? Question 13 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 14 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? Question 15 Which of the following is not a disadvantage of a within subjects design?  2 out of 2 points Question 16  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 17 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 18 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 19 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 20 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 21 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 22 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 23 occur when participants improve performance due to subsequent experiences on the same task. Question 24 Participants experiencing the same order of presentation of the levels of the independent variable can lead to . Question 25 In a , participants will be exposed to only one level of the independent variable. Question 26  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 27 occurs when the effects of a prior condition influence subsequent treatment conditions. Question 28 The degree of spread among data surrounding the mean is known as . Question 29 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 30  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?
