1. What is the term for a fluid-filled sac in which the baby floats until just before it is born?

• A. Amnion
• B. Placenta
• C. Umbilical cord
• D. Embryo

Correct answer: A

Rationale: The correct answer is A: Amnion. The amnion is a fluid-filled sac that surrounds and protects the developing fetus in the womb. It acts as a cushion, maintaining a stable temperature and protecting the fetus from external pressure. Choices B, C, and D are incorrect because the placenta is an organ that provides nutrients and oxygen to the fetus and removes waste products, the umbilical cord connects the fetus to the placenta to facilitate nutrient exchange, and an embryo is an early stage of development before it becomes a fetus.

2. Who proposed that the study of consciousness should be replaced by the study of behavior?

• A. John Watson
• B. Abraham Maslow
• C. G. Stanley Hall
• D. Sigmund Freud

Correct answer: A

Rationale: The correct answer is John Watson. Watson, a key figure in behaviorism, believed that psychology should focus on observable behavior rather than consciousness. Abraham Maslow is known for his hierarchy of needs theory and humanistic psychology, not for advocating the study of behavior over consciousness. G. Stanley Hall was a pioneer in psychology but did not propose replacing the study of consciousness with behavior. Sigmund Freud, a prominent figure in psychoanalysis, focused on the unconscious mind rather than behavior.

3. Cortisol is a hormone that ________

• A. is released by the hypothalamus and travels to the pituitary gland, causing it to respond.
• B. the pituitary gland releases to stimulate the adrenal gland.
• C. the adrenal gland produces that mobilizes the body to deal with stress.
• D. reduces the reuptake of the monoamine neurotransmitters.

Correct answer: C

Rationale: The correct answer is C. Cortisol is a hormone produced by the adrenal gland that mobilizes the body to deal with stress. It helps regulate metabolism, reduce inflammation, and assist in memory formulation. Choice A is incorrect as cortisol is not released by the hypothalamus and does not travel to the pituitary gland. Choice B is incorrect as cortisol is not released by the pituitary gland but acts on it to regulate hormone production. Choice D is incorrect as cortisol does not reduce the reuptake of monoamine neurotransmitters.

4. Distinguish between assimilation and accommodation.

• A. Assimilation refers to adjusting our mental frameworks to incorporate new information.
• B. Assimilation is when new experiences are interpreted in terms of existing schemas.
• C. Assimilation is adapting our behaviors to match societal norms.
• D. Assimilation and accommodation are unrelated to cognitive development.

Correct answer: B

Rationale: The correct answer is B. Assimilation is when new experiences are interpreted in terms of existing schemas, meaning individuals try to fit new information into their pre-existing understanding of the world. Accommodation, on the other hand, involves adjusting our schemas to fit new information, which means changing our existing mental frameworks when new information doesn't fit. Choice A is incorrect because it describes accommodation rather than assimilation. Choice C is incorrect as it confuses assimilation with social adaptation. Choice D is incorrect as assimilation and accommodation are fundamental processes in cognitive development, as described by Piaget.

5. What neurotransmitter was first believed to be the cause of schizophrenia?

• A. GABA
• B. Serotonin
• C. Epinephrine
• D. Dopamine

Correct answer: D

Rationale: The correct answer is Dopamine. Dopamine was initially thought to be the primary cause of schizophrenia. This neurotransmitter hypothesis was based on the observation that drugs that increase dopamine activity can worsen symptoms of schizophrenia, while drugs that decrease dopamine activity can improve symptoms. Choices A, B, and C are incorrect because GABA, serotonin, and epinephrine were not the neurotransmitters initially believed to be the cause of schizophrenia.
