1. 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.

2. 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.

3. A newspaper article reported a study by a psychologist in which the attitudes of men and women toward traditional sex roles were studied. Most likely, the researcher was?

• A. A cognitive psychologist.
• B. A counseling psychologist.
• C. A developmental psychologist.
• D. A social psychologist.

Correct answer: D

Rationale: The correct answer is D, a social psychologist. Social psychologists focus on how societal factors, including norms and expectations, influence behaviors and attitudes. In this case, studying the attitudes of men and women toward traditional sex roles aligns with the research domain of social psychology. Choices A, B, and C are incorrect because cognitive psychologists focus on mental processes, counseling psychologists on helping individuals with personal and interpersonal issues, and developmental psychologists on human growth and development, respectively, which are not directly related to studying attitudes towards traditional sex roles influenced by societal factors.

4. What role does brain development play in psychopathology?

• A. Brain development has no impact on psychopathology.
• B. Brain development plays a crucial role in the onset of many mental disorders.
• C. Brain development is only linked to physical disabilities, not mental disorders.
• D. Brain development is not associated with mental health.

Correct answer: B

Rationale: Brain development plays a crucial role in the onset of many mental disorders. It affects how the brain processes information and responds to stress, influencing the development of psychopathology. Choice A is incorrect as brain development does impact psychopathology. Choice C is incorrect as brain development is linked to mental disorders as well. Choice D is incorrect as brain development has implications for mental health.

5. A baby throws its arms out and then inward (as if embracing) in response to loud noise or when its head falls. Which reflex is this?

• A. Babinski
• B. Palmar
• C. Darwinian
• D. Moro

Correct answer: D

Rationale: The correct answer is D, Moro. The Moro reflex is an instinctual response seen in infants when they experience a sudden loss of support or loud noise. The baby will throw their arms out and then bring them back in, resembling an embrace. This reflex is important for survival as it helps the infant react to potential dangers. Choice A, Babinski, refers to the reflex where a baby's toes spread apart when the sole of the foot is stimulated. Choice B, Palmar, is related to the reflex where a baby's fingers close tightly around an object placed in their palm. Choice C, Darwinian, is not a recognized reflex in this context.
