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. After cheating on her husband and feeling ashamed, Julia accused her husband of cheating. Such behavior is explained by which of the following defense mechanisms?

• A. Sublimation
• B. Displacement
• C. Projection
• D. Rationalization

Correct answer: C

Rationale: The correct answer is C, Projection. Projection is the defense mechanism where one attributes their own unacceptable feelings to others. In this scenario, Julia is projecting her feelings of guilt and shame onto her husband by accusing him of cheating. Sublimation (choice A) involves channeling unacceptable impulses into socially acceptable activities. Displacement (choice B) is redirecting emotions from the original source to a substitute target. Rationalization (choice D) is providing logical explanations to justify unacceptable behavior, which is not applicable in this context.

3. If a pair of monozygotic twins raised in the same environment end up being different from one another (e.g., interests, hobbies, etc.), it is highly likely due to:

• A. Cephalocaudal pattern
• B. Proximodistal pattern
• C. Cephamodistal pattern
• D. Gene-environment correlation

Correct answer: B

Rationale: The correct answer is B: Proximodistal pattern. Differences between monozygotic twins raised in the same environment are likely due to non-shared environmental influences, which lead to differences in interests, hobbies, and other individual characteristics. Choices A, C, and D are incorrect. Cephalocaudal pattern refers to the principle of development from head to toe, not relevant in explaining differences between twins. Cephamodistal pattern is not a recognized developmental term. Gene-environment correlation does not directly explain the differences between identical twins raised in the same environment.

4. The ability to adapt successfully to even very difficult circumstances is called ________.

• A. resilience
• B. hardiness
• C. perseverance
• D. a challenge orientation

Correct answer: A

Rationale: Resilience is indeed the correct term for the ability to adapt successfully to difficult circumstances. Resilience involves bouncing back from setbacks, handling stress, and persevering in the face of adversity. Choice B, 'hardiness,' refers more to toughness or durability rather than adapting to difficult circumstances. Choice C, 'perseverance,' is about persistence and determination rather than adaptability. Choice D, 'a challenge orientation,' does not directly relate to the ability to adapt to difficult circumstances, making it an incorrect choice.

5. How does stress impact brain function?

• A. Stress has no effect on brain function.
• B. Stress can lead to changes in brain structure and function.
• C. Stress can improve brain function.
• D. Stress has no long-term impact on brain function.

Correct answer: B

Rationale: Stress can lead to changes in brain structure and function, affecting mental health and increasing the risk of disorders. Choice A is incorrect as stress does affect brain function. Choice C is incorrect as stress generally has negative impacts on brain function rather than improving it. Choice D is incorrect because stress can have long-term impacts on brain function through structural and functional changes.
