Rationale: Oliver's roommate holds a humanistic perspective. This perspective emphasizes human uniqueness and may devalue information obtained from animal studies when studying human experiences. The humanistic perspective focuses on subjective experiences, free will, and personal growth, which aligns with his roommate's belief that animal studies won't provide meaningful information about human experiences. Choice B, an evolutionary perspective, would focus on the role of evolution in shaping behavior, not directly related to the roommate's view. Choices C and D, biological and cognitive perspectives respectively, do not directly address the roommate's skepticism toward using animal studies to understand human motivation.

Correct Answer: D

Rationale: The correct order of the three stages of prenatal development is germinal stage, embryonic stage, and fetal stage. During the germinal stage, the fertilized egg rapidly divides and implants in the uterine wall. The embryonic stage follows, where major organs and systems begin to develop. Finally, during the fetal stage, the developing organism is known as a fetus and continues to grow and mature. Choice A is incorrect because it has the stages in the wrong order. Choice B is incorrect as it also presents the stages out of order. Choice C is incorrect as it reverses the order of the stages. Therefore, the correct answer is D.

Correct Answer: B

Choice C is incorrect as critical period refers to specific time frames for development, not a set of age norms. Choice D, sensitive period, does not directly relate to the concept described in the question.

Correct Answer: D

Rationale: Subjective distress is not universal among individuals with a mental disorder. Choice A is incorrect as not all individuals with mental illness experience distress. Choice B is incorrect because distress is just one of the criteria used in diagnosing abnormality, not the only one. Choice C is incorrect because the presence of subjective distress alone is not sufficient for a clinician to determine if someone has a mental illness.
