1. Why do young infants usually cry?

• A. because they are bored
• B. in shrill, piercing tones
• C. because of physical needs
• D. all night long

Correct answer: C

Rationale: Young infants usually cry because of physical needs such as hunger, discomfort, or needing to be changed. It is their way of communicating these needs to their caregivers as they are unable to do so in any other way. Choice A is incorrect because infants cry primarily to communicate physical needs, not because they are bored. Choice B is incorrect because the tone of the cry is not the reason why infants cry. Choice D is incorrect because infants cry for various physical needs, not necessarily all night long.

2. According to __________ theory, children learn primarily through modeling.

• A. reinforcement
• B. operant conditioning
• C. social learning
• D. classical conditioning

Correct answer: C

Rationale: According to social learning theory, children primarily learn through modeling, observation, and imitation of others. This theory emphasizes the importance of cognitive processes in learning, as opposed to only focusing on direct reinforcement or punishment. Social learning theory was developed by psychologist Albert Bandura and is a key theory in the field of child development. Choice A, reinforcement, is incorrect as it refers to the process of strengthening a behavior through rewards or punishments. Choice B, operant conditioning, is also incorrect as it is a learning process that involves reinforcement and punishment to shape behavior. Choice D, classical conditioning, is not the correct answer as it involves learning through association between stimuli.

3. Which statement about the harm done by teratogens is true?

• A. Passive smoking can be harmful to the developing fetus.
• B. The genetic makeup of the mother and the developing organism plays an important role.
• C. The negative impact of teratogens is usually reversible.
• D. The most serious defects occur in the germinal period.

Correct answer: B

Rationale: The statement that the genetic makeup of the mother and the developing organism plays an important role in the harm done by teratogens is true. Genetic factors can influence susceptibility to teratogens, and the interaction between genetic and environmental factors plays a significant role in determining the impact on the developing fetus. This highlights the importance of considering both genetic and environmental influences when assessing risks to prenatal development. Choice A is incorrect as passive smoking can indeed be harmful to the developing fetus. Choice C is incorrect as the negative impact of teratogens is often not reversible. Choice D is incorrect as serious defects can occur throughout prenatal development, not just in the germinal period.

4. Lanugo ________.

• A. permits food and oxygen to reach the organism
• B. provides the fetus a cushion against jolts caused by the mother's movements
• C. helps regulate the fetus's body temperature
• D. helps the vernix stick to the skin

Correct answer: D

Rationale: Lanugo helps the vernix stick to the skin. Vernix is a waxy substance that covers the fetus's skin during pregnancy. Lanugo is a fine, downy hair that helps to anchor the vernix to the skin, providing protection and nourishment to the developing fetus. Choices A, B, and C are incorrect as they do not accurately describe the role of lanugo in prenatal development.

5. Which state of arousal is considered the most fleeting?

• A. Regular sleep
• B. REM sleep
• C. Drowsiness
• D. Quiet alertness

Correct answer: D

Rationale: Quiet alertness is indeed the most fleeting state of arousal. This state is characterized by a newborn infant being awake, calm, and attentive, but it is short-lived and transitions quickly to other states of arousal. Regular sleep, REM sleep, and drowsiness are not considered as brief and transitional as quiet alertness in newborn infants.
