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 favorite toys from most favorite to least favorite. 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
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) CORRECT 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 psych legal 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 students. To keep work at a manageable level, the educator decided to change morning
class period duration from 45 to 90 minutes so that material that was previously covered
in 20 weeks was now covered in 10 weeks. No change was introduced to the afternoon class periods. In other words, the total amount of class time on any subject remained
