Question 1
1/ 1pts
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?
43
10
2
None of the above
Question 2
1/ 1pts
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?
the time to complete the task
the Stroop effect
the stimuli in the study
participants’ reaction time
Question 3

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 _________.
practice effects.
order effects.
presentation effects.
all of the above.
Question 4
1/ 1pts
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?
10 participants
30 participants
none of the above
cannot be determined

fatigue
order effects
fewer participants
Question 7

When the effects of a prior treatment condition influences subsequent
treatment conditions, a researcher is faced with this disadvantage to a within
subject design.
order effects
carryover effects
guitar effects
attrition
Question 8
1/ 1pts
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?
between subjects design
within subjects design
mixed subjects design
within participant design
Question 9
1/ 1pts
_________ occurs when the effects of a prior condition influence subsequent
treatment conditions.
Transformation
Carryover
Conversion
Residual
Question 10
1/ 1pts
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?
There were varying numbers of participants in the groups.
The participants did not become fatigued.
They could use multiple dependent measures.
There were no concerns with practice effects.
IncorrectQuestion 11

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?
types of music
the performance on the computer games
playing computer games
neutral music

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?
Pepsi challenge
reported taste of the drinks
the different colas
the labels on the drinks
Question 13

parts to a study is known as __________.
attrition.
mortality.

is correct?
Participants are exposed to only one level of the independent variable.
Participants are exposed to all levels of the independent variable.
Participants are exposed to a maximum of two levels of the independent
variable.
