With Solved Solutions.
Consider the following statement, "If negative emotions cause aggression, and if frustration
induces negative emotion, then frustration must cause aggression." Which one of the following
ways of knowing does this statement illustrate? - Answer Logic
Determinism is the doctrine that all events: - Answer Are Caused
The fact that the order in which something occurs is important in establishing a cause and effect
relationship is called: - Answer Temporal Precedence
Consider the following research title: "Cooperation among nursery school children under two
types of instruction." In this study, the independent variable is: - Answer Type of Instruction
At a day care centre, a researcher asks children to list their five favourite toys from most
favourite to least favourite. What level of measurement is represented in this example? -
Answer Ordinal
An experiment in which the independent variable really caused the change in the dependent
variable is said to be high in __________ validity. - Answer Internal
Which of the following potential threats to internal validity is a researcher concerned about
when she asks, "Have research participants with extreme scores on the variable of interest been
pre-selected for the study"? - Answer Regression Effect
A between-subjects experiment is one in which each subject: - Answer experiences only one
of the conditions.
Role demands are a source of: - Answer Subject Bias
What is the main purpose of matching? - Answer to reduce initial differences between the
experimental and control groups on the dependent variable
, "rats that are fed a high-fat diet will reduce their weight after they return to their normal diets"
This statement builds trust in the theory because it acts like proof that the brain (which is the
rat's brain) does try to maintain an ideal weight when the rat's body weight is increased.
c.) Identify one statement of fact. How is the fact explained by the theory?
"he remembered that the weight he had put on over Christmas holidays went away after he
returned to college"
This statement is a fact since Juan knows that it is true. This may be explained by theory as it is
an indication that the brain is able to act as a thermostat to maintain a specific weight. To
clarify, when Juan went home for Christmas, his weight increased above his normal set point in
which that was normal to the body. However, when he returned back to college, Juan's brain
worked to bring Juan's weight down to his original weight. (the weight before Christmas)
Suggest an operational definition for each of the following constructs: (3 points) - Answer
Aggression
Aggression can be measured by how many times a participant clenches their fist in a study
Hunger
Hunger can be measured by the amount of times a participant inquires about when food will be
presented in a study during which researchers will not provide lunch until past 12 noon.
Intelligence
Intelligence can be measured using standardized IQ tests
Do Exercise 5.3: Identify Variables, on page 139 of Research Methods. (2 points) - Answer a.)
What is (are) the independent variable(s)?
Psycholegal knowledge
b.) What were the levels (conditions) of the independent variables?
ONE completion of a university course on psychology and law focusing on jury decision-making
(experiment group)
TWO the course is not taken by the participants (control group)
c.) What is (are) the dependent variable(s)?
The mock jury's decision-making
d.) Which sentence states a hypothesis?
"it was predicted that psycholegal knowledge would enhance juror competence, motivation,
and satisfaction with participation in the legal process"
An educator wanted to test the effects of class period duration on learning of junior-high
