Small-for-date infants __________ than preterm infants.
- A. catch fewer infections during the first year
- B. are less likely to die during the first year
- C. more often show evidence of brain damage
- D. have higher intelligence tests by middle childhood
Correct Answer: C
Rationale: Small-for-date infants more often show evidence of brain damage than preterm infants. This can be attributed to factors such as intrauterine growth restriction and poor nutrition during pregnancy, which can affect the development of the baby's brain. Choices A, B, and D are incorrect because there is no evidence to support that small-for-date infants catch fewer infections, are less likely to die, or have higher intelligence tests compared to preterm infants.

Which statement about the newborn baby's appearance is true?
- A. Girls tend to be slightly longer and heavier than boys.
- B. Their round faces and big eyes make adults feel like picking them up.
- C. The trunk is large in comparison to the head, and the legs are straight.
- D. On average, they are 18 inches long and 5½ pounds in weight.
Correct Answer: C
Rationale: The correct statement about the newborn baby's appearance is that the trunk is large in comparison to the head, and the legs are straight. This is a common characteristic of newborn babies as their proportions are different from adults. Choice A is incorrect as there is no consistent trend of girls being longer and heavier than boys at birth. Choice B is incorrect as the perception of adults wanting to pick up babies is subjective and not a universal truth. Choice D is incorrect as the average length and weight provided may not apply to all newborn babies, as there can be variations.
Terrance, whose birth mother drank heavily throughout pregnancy, has a thin upper lip, short eyelid openings, a small head, and a smooth philtrum. His physical growth has been slow, and he shows impairment in memory, attention span, motor coordination, and social skills. Terrance has __________.
- A. fetal alcohol syndrome
- B. partial fetal alcohol syndrome
- C. alcohol-related neurodevelopmental disorder
- D. cytomegalovirus
Correct Answer: A
Rationale: Terrance exhibits a combination of physical abnormalities like a thin upper lip, short eyelid openings, a small head, and a smooth philtrum, along with developmental delays and cognitive impairments. These characteristics are indicative of fetal alcohol syndrome (FAS), which is caused by maternal alcohol consumption during pregnancy. FAS is a severe condition resulting from prenatal alcohol exposure and is characterized by a range of physical, cognitive, and behavioral issues. Choice A, fetal alcohol syndrome, is the correct answer as it aligns with Terrance's symptoms and the effects of maternal alcohol consumption during pregnancy. Choices B, C, and D are incorrect because they do not encompass the full spectrum of symptoms and impairments presented by Terrance, which are specific to fetal alcohol syndrome.
Observations of imprinting led to which major concept in human development?
- A. adaptation
- B. equilibrium
- C. the critical period
- D. classical conditioning
Correct Answer: C
Rationale: Observations of imprinting in animals, such as ducklings following the first moving object they see after hatching, led to the major concept of the critical period in human development. The critical period is a specific time frame during which an organism must experience certain stimuli to develop properly. This concept has been influential in understanding various aspects of human development, such as language acquisition and social attachment. Choices A, B, and D are incorrect. Adaptation refers to adjusting to the environment, equilibrium is about balance in cognitive processes, and classical conditioning is a learning process associated with behaviorism, none of which directly relate to the concept derived from imprinting observations.
Baby Gabriella claps her hands after her mother does. Gabriella is displaying __________.
- A. reinforcement
- B. classical conditioning
- C. observational learning
- D. adaptation
Correct Answer: C
Rationale: Observational learning is when an individual learns by watching others and mimicking their actions or behaviors. In this scenario, Baby Gabriella claps her hands after her mother does, indicating she is learning through observing her mother's behavior and imitating it. The other choices are incorrect: Reinforcement typically involves a consequence that strengthens a behavior, classical conditioning is a type of learning where an association is made between two stimuli, and adaptation refers to the process of adjusting to new conditions.
The force of blood flowing through the __________ keeps it firm.
- A. amnion
- B. umbilical cord
- C. yolk sac
- D. embryonic disk
Correct Answer: B
Rationale: The force of blood flowing through the umbilical cord keeps it firm. The umbilical cord is the connection between the placenta and the fetus, providing essential nutrients and oxygen to the developing baby. Blood flow through the umbilical cord helps maintain its structure and function throughout the prenatal period. Choices A, C, and D are incorrect as they do not play a role in providing nutrients and oxygen to the developing baby or in maintaining its firmness.
