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. You are taking part in a survey that asks about your attitudes toward physical punishment of children. Even though you believe that spanking is sometimes necessary, you answer that you are opposed to any sort of physical punishment. Which of the following terms best describes why you answered the way you did?

• A. Random responding
• B. Faking bad
• C. Placebo effect
• D. Social desirability

Correct answer: D

Rationale: The correct answer is D, social desirability. Social desirability bias occurs when respondents answer questions in a way they think will be viewed favorably by others, rather than according to their true beliefs. In this scenario, the respondent may feel pressured to provide an answer that aligns with societal norms or expectations, even if it contradicts their personal beliefs. Choices A, B, and C are incorrect. Random responding refers to answering survey questions haphazardly, without consideration. Faking bad is intentionally providing extreme or negative responses. The placebo effect is a phenomenon where a person's belief in a treatment's effectiveness produces a positive outcome, unrelated to the treatment's actual effects.

3. Scientific research has demonstrated the __________ parenting style is most likely to lead to healthy psychological development in children.

• A. Authoritarian
• B. Permissive
• C. Authoritative
• D. Neglectful

Correct answer: C

Rationale: Scientific research has demonstrated that the authoritative parenting style is most likely to lead to healthy psychological development in children. Authoritative parents are responsive to their children's emotional needs, set clear boundaries, and encourage independence. This balance fosters a positive environment for children to thrive emotionally and psychologically. Authoritarian parenting (choice A) focuses on strict rules without much warmth, which can lead to obedience but may hinder emotional development. Permissive parenting (choice B) lacks structure and rules, potentially resulting in children feeling insecure. Neglectful parenting (choice D) is characterized by a lack of responsiveness and involvement, leading to various negative outcomes for the child's development.

4. Distinguish between necessary, sufficient, and contributory causes of abnormal behavior.

• A. Necessary causes are required for a disorder to develop but do not guarantee it.
• B. Sufficient causes guarantee a disorder will develop, but they are not required.
• C. Contributory causes increase the likelihood of a disorder but are neither necessary nor sufficient.
• D. Contributory causes are conditions that guarantee the occurrence of a disorder.

Correct answer: A

Rationale: In understanding abnormal behavior, it is crucial to differentiate between necessary, sufficient, and contributory causes. Necessary causes are those that are required for a disorder to develop, meaning that without them, the disorder would not occur. However, their presence does not guarantee the occurrence of the disorder. Sufficient causes, on the other hand, are those that alone can guarantee the development of a disorder, but they are not the only factors that can lead to it. Contributory causes are factors that increase the likelihood of a disorder but are not essential on their own nor do they guarantee the disorder. Therefore, choice A is the correct answer as it accurately describes the role of necessary causes in the development of abnormal behavior. Choices B, C, and D are incorrect as they misrepresent the definitions and roles of sufficient and contributory causes in causing abnormal behavior.

5. How do neurotransmitters affect behavior and mental processes?

• A. Neurotransmitters have little effect on behavior.
• B. Neurotransmitters are chemicals that influence mood, thought, and behavior.
• C. Neurotransmitters have a minor role in mental health.
• D. Neurotransmitters determine intelligence levels.

Correct answer: B

Rationale: Neurotransmitters are chemicals that influence mood, thought, and behavior, playing a significant role in mental health. Choice A is incorrect as neurotransmitters do have a notable effect on behavior. Choice C is incorrect as neurotransmitters have a major role in mental health. Choice D is incorrect as neurotransmitters do not solely determine intelligence levels.
