1. Why is it particularly useful to study identical twins who were raised in different environments?

A. Differences in brain function can be easily identified.
B. Concordance rates tend to be higher.
C. It is possible that the genetics of twins who have been separated have changed in ways to explain any differences found.
D. It is possible that high concordance rates between identical twins reared together are due to their being treated more similarly than nonidentical twins.

Correct answer: D

Rationale: Studying identical twins raised in different environments allows researchers to understand the impact of genetics versus environmental factors on traits. Choice A is incorrect because differences in brain function can be influenced by a variety of factors and not solely by environmental differences. Choice B is incorrect as concordance rates tend to be higher in identical twins reared together due to shared genetics and environment. Choice C is incorrect because genetics do not change due to being raised in different environments.

2. Sigmund Freud developed an innovative procedure for treating people with psychological problems, which he called?

A. Behavior modification.
B. Primal therapy.
C. Psychoanalysis.
D. Rational-emotive therapy.

Correct answer: C

Rationale: Sigmund Freud developed psychoanalysis, not behavior modification, primal therapy, or rational-emotive therapy, as an innovative method for treating psychological problems. Psychoanalysis focuses on exploring unconscious motivations to understand and address psychological disorders, making it the correct answer. Behavior modification involves changing behavior through conditioning techniques, primal therapy emphasizes expressing repressed emotions, and rational-emotive therapy aims to identify and change irrational beliefs.

3. Rita shows better control over her eating habits at 2.5 years than her brother Richard did at the same age. Why?

A. Girls are naturally smarter than boys.
B. Second-born children learn faster.
C. Girls have better fine motor skills.
D. Boys have better gross motor skills.

Correct answer: D

Rationale: The correct answer is D because boys typically develop gross motor skills, like running and jumping, more quickly than girls. This can explain why Richard may have had less control over his eating habits compared to Rita at the same age. Choices A, B, and C are incorrect because they do not address the specific developmental aspect related to eating habits control mentioned in the question.

4. What is the biopsychosocial model, and why is it important?

A. A model that integrates biological, psychological, and social factors.
B. A model that focuses solely on biological factors.
C. A model that excludes social factors.
D. A model that focuses solely on psychological factors.

Correct answer: A

Rationale: The biopsychosocial model is a model that integrates biological, psychological, and social factors. It is important because it recognizes the interconnectedness of these factors in influencing an individual's mental health. Option B is incorrect because the biopsychosocial model does not focus solely on biological factors. Option C is incorrect as the model does not exclude social factors. Option D is incorrect as the model does not focus solely on psychological factors.

5. John Bowlby's attachment theory emphasized ________.

A. the social environment in forming attachments.
B. the quality of parental care in forming attachments.
C. the quality of early reinforcers and stimulation in forming attachments.
D. the necessity of independence from parental figures in forming attachments.

Correct answer: B

Rationale: John Bowlby's attachment theory emphasized the quality of parental care in forming attachments. This is because Bowlby believed that a child's early experiences with their primary caregiver, especially the quality of care and responsiveness received, significantly influence the child's ability to form secure attachments. Choice A is incorrect because while the social environment plays a role, Bowlby's theory focused more on the caregiver-child relationship. Choice C is incorrect as it does not capture the central role of parental care highlighted in Bowlby's theory. Choice D is also incorrect as Bowlby's theory actually emphasized the importance of a secure attachment to parental figures for healthy emotional development.
