Human Growth and Development Final Exam Answers
1. In the last weeks of pregnancy, __________.
- A. the fetus usually loses weight
- B. most fetuses assume an upside-down position
- C. fetal growth increases dramatically
- D. the fetus relies on its own well-developed immune system
Correct answer: B
Rationale: In the last weeks of pregnancy, most fetuses assume an upside-down position known as the head-down position or vertex presentation. This position is ideal for a smoother labor and delivery process as it helps the baby move through the birth canal. Fetal growth has already slowed down at this stage, so option C is incorrect. Option A is inaccurate as the fetus typically gains weight in the final weeks. Option D is incorrect because the fetus relies on the mother's immune system while in the womb.
2. Which statement provides an example of an age-graded influence?
- A. Paul learned to play the violin at a young age.
- B. Jack enjoys hiking in the mountains.
- C. Sarah prefers reading mystery novels.
- D. Alex excels in mathematics.
Correct answer: A
Rationale: The corrected statement 'Paul learned to play the violin at a young age' provides an example of an age-graded influence. This is because learning to play the violin is a behavior that is typical or expected at a certain age, reflecting how age influences individuals' experiences and development. In contrast, choices B, C, and D do not directly relate to age-graded influences. Jack's enjoyment of hiking, Sarah's preference for reading mystery novels, and Alex's proficiency in mathematics are not inherently tied to age-related developmental influences.
3. Tiffany is a small-for-date baby. This means she __________.
- A. was born several weeks or more before her due date
- B. was born below her expected weight considering the length of the pregnancy
- C. will probably have much less serious problems than a preterm infant
- D. may have difficulties in infancy but will outgrow them by the preschool years
Correct answer: B
Rationale: A small-for-date baby, also known as a small-for-gestational-age (SGA) baby, is a baby who is born below their expected weight considering the length of the pregnancy. This can be due to various factors including issues with growth restriction in the womb. Being small-for-date is different from being preterm (born prematurely) and does not necessarily mean that the baby was born early. Choice A is incorrect because being small-for-date does not specifically indicate being born several weeks or more before the due date. Choice C is incorrect because being small-for-date does not guarantee fewer problems than a preterm infant, as each baby's health outcomes can vary. Choice D is incorrect because while small-for-date babies may have initial difficulties, it does not guarantee that these issues will be outgrown by the preschool years.
4. In mammals, including humans, the sense of smell __________.
- A. does not become adultlike for several years
- B. helps mothers and babies identify each other
- C. is the least developed sense at birth
- D. takes about four months to become adultlike
Correct answer: B
Rationale: The sense of smell in mammals, including humans, plays a crucial role in helping mothers and babies identify each other. This is important for initiating bonding and caregiving behaviors. Choice A is incorrect because the sense of smell is functional at birth and not entirely underdeveloped for several years. Choice C is incorrect as the sense of smell is actually well-developed at birth. Choice D is incorrect because the sense of smell is functional from birth and does not take several months to become adultlike.
5. Children in middle childhood are in Piaget's _______ stage, which extends from about 7 to 11 years.
- A. sensorimotor
- B. preoperational
- C. concrete operational
- D. formal operational
Correct answer: C
Rationale: The correct answer is C: concrete operational. During the concrete operational stage, children start to engage in logical thinking about concrete events. This stage typically occurs between the ages of 7 to 11 years. Choices A, B, and D are incorrect. The sensorimotor stage (choice A) is the first stage in Piaget's theory, occurring from birth to about 2 years old. The preoperational stage (choice B) follows the sensorimotor stage and occurs roughly from ages 2 to 7 years. The formal operational stage (choice D) is the final stage in Piaget's theory, where abstract thinking and hypothetical reasoning develop, usually beginning around age 11.
