1. During conception, the 23 unpaired chromosomes in the ovum and sperm combine to form 23 pairs in an entirely new cell called the?

• A. Embryo
• B. DNA
• C. Fetus
• D. Zygote

Correct answer: D

Rationale: The correct answer is D, Zygote. A zygote is formed when the 23 chromosomes from the ovum and sperm combine during conception. It is the initial cell formed and marks the beginning of a new organism. Choice A, Embryo, is incorrect as an embryo is formed later in the development process. Choice B, DNA, is incorrect as DNA is the genetic material within the chromosomes but is not the name of the new cell formed after fertilization. Choice C, Fetus, is incorrect as a fetus is the stage of prenatal development that occurs well after the zygote stage.

2. Which term describes the conditions that guarantee the occurrence of a disorder?

• A. Necessary causes
• B. Contributory causes
• C. Sufficient causes
• D. Protective factors

Correct answer: C

Rationale: The correct answer is 'Sufficient causes.' Sufficient causes are conditions that alone are enough to guarantee the occurrence of a disorder. Necessary causes refer to factors that must be present for the disorder to occur but are not enough on their own. Contributory causes increase the likelihood of a disorder but are not enough to cause it by themselves. Protective factors are conditions that reduce the likelihood of a disorder occurring.

3. 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.

4. When interviewing a new member of the psychology department for the university newspaper, the faculty member states, 'Internal states undoubtedly exist, but it is not necessary to draw inferences about unobservable states in order to understand behavior.' This faculty member's views are most similar to the views held by?

• A. William James.
• B. F. Skinner.
• C. Sigmund Freud.
• D. Carl Rogers.

Correct answer: B

Rationale: F. Skinner's views emphasized the importance of observable behavior and dismissed the need to infer unobservable mental states. This aligns with the faculty member's statement that internal states exist but are not essential for understanding behavior. William James, known for his work in functionalism, did consider internal mental states important. Sigmund Freud focused on unconscious motives and internal conflicts. Carl Rogers emphasized the importance of subjective experiences and personal growth, which differs from the faculty member's perspective.

5. What does the diathesis-stress model entail?

• A. The diathesis-stress model suggests that stress alone is sufficient to cause a mental disorder.
• B. The diathesis-stress model involves a combination of genetic vulnerability and environmental stressors.
• C. The diathesis-stress model suggests that genetic factors alone cause mental disorders.
• D. The diathesis-stress model suggests that stressors in the environment do not affect the onset of mental disorders.

Correct answer: B

Rationale: The diathesis-stress model proposes that mental disorders develop from a combination of genetic vulnerability (the diathesis) and environmental stressors. Choice A is incorrect because it states that stress alone can cause mental disorders, which is not in line with the model. Choice C is incorrect as it simplifies the model to genetic factors alone causing mental disorders. Choice D is incorrect as it suggests that environmental stressors do not play a role in the onset of mental disorders, which contradicts the essence of the diathesis-stress model.
