1. How is pruning best defined?

• A. The process of eliminating unused synapses
• B. The process of synapse development
• C. The connection between neurons
• D. Fatty sheath that wraps around neurons and enables them to transmit information more rapidly

Correct answer: A

Rationale: Pruning is the process of eliminating unused synapses in the brain. This process helps the brain to become more efficient by strengthening important connections and eliminating unnecessary ones. Choice B is incorrect because pruning is about eliminating synapses, not developing them. Choice C is incorrect as it refers to the general concept of connections between neurons, not specifically about pruning. Choice D is incorrect as it describes the myelin sheath, which is responsible for rapid transmission of information along neurons, not pruning.

2. Which of the following is a common effect of persistent discrimination?

• A. Increased happiness
• B. Greater intelligence and wisdom
• C. Cardiovascular reactivity
• D. Increased consciousness

Correct answer: C

Rationale: The correct answer is C: Cardiovascular reactivity. Persistent discrimination can have negative impacts on an individual's physical health, leading to increased cardiovascular reactivity. This can manifest as higher blood pressure, heart rate, and overall stress on the cardiovascular system. Choices A, B, and D are incorrect because persistent discrimination typically does not result in increased happiness, greater intelligence and wisdom, or increased consciousness. Instead, it often leads to detrimental effects on mental and physical health.

3. What is the current view of developmentalists regarding important changes throughout the entire human lifespan?

• A. Multicultural perspective
• B. Lifespan perspective
• C. Atypical development
• D. Maturation

Correct answer: B

Rationale: The correct answer is 'Lifespan perspective.' This perspective highlights that significant developmental changes occur throughout a person's entire life, emphasizing continuous growth and development. Choice A, 'Multicultural perspective,' refers to the consideration of cultural influences on development rather than the timeline of changes. Choice C, 'Atypical development,' pertains to deviations from typical developmental patterns and is not directly related to the continuous changes across the lifespan. Choice D, 'Maturation,' specifically refers to the biological process of growth and development, which is different from the broader concept of developmental changes occurring across the lifespan.

4. What role does culture play in understanding abnormal behavior?

• A. Culture plays a minimal role in understanding abnormal behavior.
• B. Culture is essential in shaping our perceptions and definitions of abnormal behavior.
• C. Culture has little impact on the expression of abnormal behavior.
• D. Culture only affects the treatment of abnormal behavior, not its understanding.

Correct answer: B

Rationale: Culture is essential in shaping our perceptions and definitions of abnormal behavior. Choice A is incorrect because culture actually plays a significant role in understanding abnormal behavior. Choice C is incorrect as culture can have a considerable impact on how abnormal behavior is expressed. Choice D is incorrect because culture influences not only the treatment but also the understanding of abnormal behavior.

5. Normal human cells have ________.

• A. twenty-two chromosome pairs and one pair of sex chromosomes.
• B. twenty-one trisomy chromosome pairs, one autosomal pair, and one pair of sex chromosomes.
• C. twenty-one chromosome pairs and two trisomy chromosome pairs.
• D. twenty-three chromosome pairs.

Correct answer: A

Rationale: The correct answer is A. Normal human cells have twenty-two chromosome pairs and one pair of sex chromosomes. This adds up to a total of 46 chromosomes. Choice B is incorrect as it mentions twenty-one trisomy chromosome pairs, which is not a characteristic of normal human cells. Choice C is also incorrect as it states twenty-one chromosome pairs and two trisomy chromosome pairs, which is not accurate for normal human cells. Choice D is incorrect as it mentions twenty-three chromosome pairs, which is not the correct number for normal human cells.
