1. What are substances, such as viruses and drugs, that can cause birth defects?

• A. Teratogens
• B. Placenta
• C. Parturition
• D. Androgens

Correct answer: A

Rationale: Teratogens are substances that can cause birth defects, especially if exposure occurs during critical periods of development. In this context, teratogens refer to external agents that can interfere with the development of the embryo or fetus, leading to structural or functional abnormalities. Choice B, Placenta, is incorrect as it is an organ that develops during pregnancy to provide nutrients and oxygen to the fetus and remove waste products. Choice C, Parturition, refers to the process of giving birth and is not related to substances that cause birth defects. Choice D, Androgens, are male sex hormones and are not associated with causing birth defects.

2. Dr. Lee is studying pain perception using a functionalist perspective. It is most likely that Dr. Lee would suggest that we can only understand the conscious experience of pain?

• A. If all the component parts that make up the experience of pain are understood.
• B. By observing the outward expression of pain in response to different stimuli.
• C. If we first understand the role of pain in human survival and adaptation.
• D. If we understand the unconscious processes that initiate the sensation of pain.

Correct answer: C

Rationale: The functionalist perspective, as used by Dr. Lee, focuses on understanding the role of pain in human survival and adaptation. This perspective suggests that to fully comprehend pain perception, one must first grasp the significance of pain in terms of its adaptive functions and impact on behavior. Choices A, B, and D do not align with the functionalist perspective, as they do not emphasize the role of pain in human survival and adaptation.

3. How does stress impact brain function?

• A. Stress has no effect on brain function.
• B. Stress can lead to changes in brain structure and function.
• C. Stress can improve brain function.
• D. Stress has no long-term impact on brain function.

Correct answer: B

Rationale: Stress can lead to changes in brain structure and function, affecting mental health and increasing the risk of disorders. Choice A is incorrect as stress does affect brain function. Choice C is incorrect as stress generally has negative impacts on brain function rather than improving it. Choice D is incorrect because stress can have long-term impacts on brain function through structural and functional changes.

4. 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.

5. Kai and Ken received their Christmas gifts from their parents. Although their gifts vary in many characteristics, the two compared their gifts based on size. This tendency among children is known as:

• A. Semiotic
• B. Abstraction
• C. Preoperational
• D. Overextension

Correct answer: D

Rationale: The correct answer is D, Overextension. Overextension happens when children compare objects or experiences based on one characteristic, such as size. Choices A, B, and C are incorrect. Semiotic refers to the study of signs and symbols; Abstraction is the process of thinking about something as a general concept rather than a specific example; Preoperational is a stage in Piaget's theory of cognitive development, not related to comparing gifts based on size.
