1. Which of the following characteristics best describes differences between bulimia nervosa and anorexia nervosa?

• A. Individuals with anorexia nervosa do not have as severe health risks as individuals with bulimia nervosa have.
• B. Individuals with bulimia nervosa may have a normal body weight.
• C. Individuals with anorexia nervosa have been known to binge like those with bulimia nervosa on occasion.
• D. Only those with bulimia nervosa display compensatory behaviors.

Correct answer: B

Rationale: The correct answer is B. Individuals with bulimia nervosa may maintain a normal body weight, while anorexia nervosa is often associated with severe underweight. Choice A is incorrect because individuals with anorexia nervosa actually face severe health risks due to malnutrition, electrolyte imbalances, and other complications. Choice C is incorrect as anorexia nervosa is characterized by restriction of food intake rather than binge eating. Choice D is incorrect as individuals with anorexia nervosa can also display compensatory behaviors such as excessive exercise or fasting.

2. Dr. Lee is studying pain perception using a functionalist perspective. It is most likely that Dr. Lee would suggest that we can only understand the conscious experience of pain?

• A. If all the component parts that make up the experience of pain are understood.
• B. By observing the outward expression of pain in response to different stimuli.
• C. If we first understand the role of pain in human survival and adaptation.
• D. If we understand the unconscious processes that initiate the sensation of pain.

Correct answer: C

Rationale: The functionalist perspective, as used by Dr. Lee, focuses on understanding the role of pain in human survival and adaptation. This perspective suggests that to fully comprehend pain perception, one must first grasp the significance of pain in terms of its adaptive functions and impact on behavior. Choices A, B, and D do not align with the functionalist perspective, as they do not emphasize the role of pain in human survival and adaptation.

3. 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.

4. Which of the following is NOT a culture-bound syndrome?

• A. Hikikomori
• B. Zar
• C. Hoopa
• D. Koro

Correct answer: C

Rationale: The correct answer is C, 'Hoopa,' as it is not recognized as a culture-bound syndrome. A culture-bound syndrome refers to a cluster of symptoms that are recognized and named within a specific cultural group but may not be recognized universally. Hikikomori is a culture-bound syndrome in Japan where individuals isolate themselves from social interactions. Zar is a culture-bound syndrome found in Africa and the Middle East characterized by episodes of laughing, crying, and singing. Koro is a culture-bound syndrome, primarily documented in Asian cultures, where individuals have an intense fear of genital retraction.

5. What is the result when a single zygote separates into two parts, each developing into a separate individual?

• A. Dizygotic twin
• B. Monozygotic twin
• C. Fraternal twin
• D. Nonidentical twin

Correct answer: B

Rationale: The correct answer is B, Monozygotic twin. A monozygotic twin, also known as an identical twin, is the result when a single zygote splits into two parts, leading to the development of two genetically identical individuals. Choices A, C, and D are incorrect because they do not accurately describe the scenario where a single zygote splits into two parts to form identical twins. Dizygotic twin (Choice A) refers to fraternal twins, which result from two separate eggs fertilized by two different sperm cells. Fraternal twin (Choice C) is another term for dizygotic twins, arising from two separate zygotes. Nonidentical twin (Choice D) is a synonymous term for dizygotic or fraternal twins, indicating that they are not genetically identical.
