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. 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: Cortisol is a hormone produced by the adrenal gland that mobilizes the body to deal with stress. Therefore, choice C is the correct answer. Choices A and B are incorrect as they inaccurately describe the origin and function of cortisol. Choice D is also incorrect as it describes the action of a different type of substance, not cortisol.

3. A baby throws its arms out and then inward (as if embracing) in response to loud noise or when its head falls. Which reflex is this?

• A. Babinski
• B. Palmar
• C. Darwinian
• D. Moro

Correct answer: D

Rationale: The correct answer is D, Moro. The Moro reflex is an instinctual response seen in infants when they experience a sudden loss of support or loud noise. The baby will throw their arms out and then bring them back in, resembling an embrace. This reflex is important for survival as it helps the infant react to potential dangers. Choice A, Babinski, refers to the reflex where a baby's toes spread apart when the sole of the foot is stimulated. Choice B, Palmar, is related to the reflex where a baby's fingers close tightly around an object placed in their palm. Choice C, Darwinian, is not a recognized reflex in this context.

4. 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.

5. 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.
