3. If a psychologist predicts that excluded participants will report more distress than included participants, which process are they using?

Correct Answer: Correct answer is: (C) Deductive reasoning from evolutionary theory to a specific testable prediction.

Exam Relevance: AP Psychology, GRE Psychology, MCAT

Difficulty: Moderate

Concept notes: Deductive reasoning involves deriving specific predictions from general principles or theories. In this case, the psychologist is using a general theory about the evolutionary basis of social exclusion to make a specific prediction about the emotional impact of exclusion.

Common Mistakes: A common mistake is confusing inductive reasoning with deductive reasoning. Inductive reasoning involves making generalizations from specific observations, which is not what the psychologist is doing here.

Explanations: The psychologist is using deductive reasoning to derive a specific prediction from a general theory. Evolutionary theory suggests that social exclusion can be distressing because it may have had negative consequences for survival and reproduction in our evolutionary past. The psychologist is applying this general principle to predict that excluded participants will report more distress than included participants.

Option Analysis:

Option A: This option describes inductive reasoning, which involves making generalizations from specific observations, not deriving specific predictions from general principles.
Option B: This option describes operational definition, which is a clear and specific description of how a variable will be measured, not the process of making a prediction.
Option C: This option correctly describes deductive reasoning, where a specific prediction is derived from a general theory.
Option D: This option describes peer review, which is a process for evaluating the scientific validity of research, not the process of making a prediction.

Mnemonic: Deductive reasoning: "General to Specific"

4. It is questionable whether all relevant variables can be matched.

Correct Answer: Correct answer is: (C) Weakness of Matched-Pair Design.

Exam Relevance: AP Psychology, GRE Psychology, Research Methods in Psychology

Difficulty: Moderate

Concept notes: Matched-pair design involves pairing participants who are similar on key variables to control for individual differences. However, it is often difficult to ensure that all relevant variables are perfectly matched.

Common Mistakes: A common misunderstanding is that matched-pair design can perfectly control for all individual differences, which is not always possible.

Explanations: Matched-pair design aims to control for individual differences by pairing participants who are similar on key variables. However, it is often challenging to identify and match all relevant variables. This limitation means that some unmeasured or uncontrolled variables may still affect the results, making it a weakness of the matched-pair design.

Option Analysis:

Option A: Independent measures design does not involve pairing participants, so the issue of matching variables is not directly relevant.
Option B: Repeated measures design involves the same participants being tested under different conditions, so the issue of matching variables is not directly relevant.
Option C: Matched-pair design involves pairing participants who are similar on key variables, but it is difficult to ensure all relevant variables are matched.
Option D: This option is incorrect as the issue is specifically related to matched-pair design.

Mnemonic: Matched pairs, match all, or fail.

5. The most frequently used quasi-experimental design is the ..... design.

Correct Answer: Correct answer is: (D) Non-equivalent comparison-group.

Exam Relevance: AP Psychology, GRE Psychology, Research Methods in Psychology

Difficulty: Moderate

Concept notes: The non-equivalent comparison-group design is a quasi-experimental design where participants are not randomly assigned to groups, but instead, pre-existing groups are compared. This design is often used when random assignment is not feasible.

Common Mistakes: A common misunderstanding is that the non-equivalent comparison-group design is the same as a true experimental design, where random assignment is used. However, in quasi-experimental designs, random assignment is not possible or practical.

Explanations: The non-equivalent comparison-group design is the most frequently used quasi-experimental design because it allows researchers to compare groups that are not randomly assigned. This design is particularly useful in situations where random assignment is not feasible, such as in educational or social settings. The design helps to control for some confounding variables by comparing groups that are similar in most respects but differ in the treatment or intervention.

Option Analysis:

Option A: Regression discontinuity design involves comparing observations close to a cutoff point, which is not as commonly used as the non-equivalent comparison-group design.
Option B: Changing-criterion design is a single-subject design used to evaluate the effects of an intervention by changing the criterion for reinforcement, which is not as widely used as the non-equivalent comparison-group design.
Option C: Interrupted time-series design involves multiple measurements before and after an intervention, which is more complex and less frequently used than the non-equivalent comparison-group design.
Option D: Non-equivalent comparison-group design is the most frequently used quasi-experimental design because it allows for comparisons between groups that are not randomly assigned, making it practical for many real-world scenarios.

6. Which is not a type of research design?
