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? - CORRECT ANSWER-Logic
Determinism is the doctrine that all events: - CORRECT ANSWER-Are Caused
,The fact that the order in which something occurs is important in establishing a cause and
effect relationship is called: - CORRECT 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: - CORRECT 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? -
CORRECT ANSWER-Ordinal
An experiment in which the independent variable really caused the change in the dependent
variable is said to be high in __________ validity. - CORRECT 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"? - CORRECT ANSWER-Regression Effect
A between-subjects experiment is one in which each subject: - CORRECT ANSWER-
experiences only one of the conditions.
Role demands are a source of: - CORRECT ANSWER-Subject Bias
, What is the main purpose of matching? - CORRECT ANSWER-to reduce initial differences
between the experimental and control groups on the dependent variable
Do Exercise 1.2: Identify Facts, Laws, and Theory on page 34 of Research Methods. (2 points) -
CORRECT ANSWER-a.) Identify a statement in the paragraph that refers to theory
"One theory of hunger motivation says that the brain acts as a feedback mechanism, something
like a thermostat, that has a set point, or ideal weight, which our body strives to maintain."
b.) Identify a statement that may be considered a law and explain how it relates to the theory.
"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) - CORRECT
ANSWER-Aggression
Aggression can be measured by how many times a participant clenches their fist in a study
