Human Growth and Development Final Exam Answers
1. 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.
2. Which statement about prenatal marijuana exposure is true?
- A. It is linked to impulsivity and overactivity.
- B. Lasting consequences are well-established.
- C. Studies show no negative effects of exposure.
- D. It is linked to an array of physical malformations.
Correct answer: A
Rationale: The correct answer is A: 'It is linked to impulsivity and overactivity.' Prenatal marijuana exposure has been associated with impulsivity and overactivity in children based on research findings. However, lasting consequences of prenatal marijuana exposure are not as well-established compared to other teratogens. Choice B is incorrect because lasting consequences are not firmly established. Choice C is incorrect because studies have shown negative effects of prenatal marijuana exposure. Choice D is incorrect as prenatal marijuana exposure is not primarily linked to physical malformations.
3. The effects of stress on the developing organism can be greatly reduced if the expectant mother __________.
- A. has access to social support during stressful periods
- B. takes a low dose of anti-anxiety medication
- C. takes a folic acid supplement early in pregnancy
- D. is placed on bed rest during the last trimester
Correct answer: A
Rationale: Having access to social support during stressful periods can greatly reduce the effects of stress on the developing organism. Social support can provide emotional comfort, practical assistance, and a sense of belonging, which can help the expectant mother cope with stress more effectively. This support system can also help mitigate the negative impact of stress on the developing baby during pregnancy. Choices B, C, and D are incorrect because while folic acid is important for prenatal health, it does not directly address the effects of stress. Taking anti-anxiety medication should be done under medical supervision and as a last resort due to potential risks to the developing baby. Bed rest during the last trimester is not a solution to reduce the effects of stress and may not address the underlying causes of stress.
4. By the end of Greta's first month of pregnancy, her embryo __________.
- A. can sense its world
- B. is about ¼ inch long
- C. can suck its thumb
- D. can curl its toes
Correct answer: B
Rationale: By the end of Greta's first month of pregnancy, her embryo is about ¼ inch long. During the first month of pregnancy, the embryo is in the very early stages of development, and its size is typically around ¼ inch as it continues to grow and develop in the uterus. Choices A, C, and D are incorrect because sensory abilities like sensing the world, sucking thumb, and curling toes develop later in the pregnancy as the embryo progresses through different stages of development.
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.
