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. 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.

3. 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.

4. What did Freud believe about castration anxiety among boys?

• A. Results in penis envy.
• B. Dissolves the Oedipus complex.
• C. Cognitive; learning.
• D. Biological; ecological.

Correct answer: B

Rationale: Freud believed that castration anxiety among boys leads to the resolution of the Oedipus complex, not penis envy or cognitive learning. The Oedipus complex is a central psychodynamic concept in Freudian theory, where boys develop unconscious desires for their mothers and view their fathers as rivals, fearing castration by their fathers as a consequence.

5. Which part of your brain is active when you get cues about being hungry, thirsty, or sleepy?

• A. Hippocampus
• B. Thalamus
• C. Hypothalamus
• D. Amygdala

Correct answer: C

Rationale: The correct answer is the Hypothalamus (Choice C). The hypothalamus plays a crucial role in regulating basic bodily functions such as hunger, thirst, and sleep. It receives cues related to these needs and helps to maintain homeostasis in the body. The Hippocampus (Choice A) is primarily involved in memory formation and spatial navigation, not in regulating physiological needs. The Thalamus (Choice B) acts as a relay station for sensory information but is not the main center for hunger, thirst, or sleep regulation. The Amygdala (Choice D) is more associated with emotions, particularly fear and pleasure, rather than physiological needs like hunger, thirst, or sleep.
