Exam 11: Within Subjects Designs

According to the text, the exposure of participants to all three monitor sizes represents a between subjects design.

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 to the independent variable in this study?

Ted is conducting a within subjects design with four levels to his independent variable.Ted 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 Ted using to limit order effects?

Which of the following is not a disadvantage of a within subjects design?

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).Which of the following is a disadvantage of this type of research design?

Within subject designs that have three levels of the independent variable need three times as many participants as a similar between subject design.

One way to minimize the order effects in a within subject design is to use counterbalancing.

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 Ouncess 24 Ouncess 10 participants 10 participants 10 participants

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?

Your friend Joe wants to know about the study on monitor size and reaction time described in question #10.Tell Joe how many groups it is possible that a particular participants would be exposed to given that the study was a within subjects design.

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.Which of the following is an advantage of this type of research design?

According to the text, the exposure of participants to all three monitor sizes represents a within subjects design.

In the Pepsi Challenge, the colas the participants drank were the independent variable.

In a within subjects design, participants are exposed to only one level of the independent variable.

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).What is the dependent variable in this study?

In Chapter 11 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?

In the Pepsi Challenge, the rating of taste the participant gave for each cola is the independent variable.

Which of the following is a disadvantage of a within subjects design?

Participant fatigue occurs when a participant drops out of study or does not return to complete additional parts to a study.

In the Pepsi Challenge, the rating of taste the participant gave for each cola is the dependent variable.
