Human Growth and Development Exam Questions
1. The mother feels a natural urge to squeeze and push with her abdominal muscles during which stage of labor?
- A. first
- B. second
- C. third
- D. fourth
Correct answer: B
Rationale: The mother feels a natural urge to squeeze and push with her abdominal muscles during the second stage of labor. This stage occurs after the cervix is fully dilated and ends with the delivery of the baby. Choice A (first) is incorrect as the first stage is mainly characterized by the dilation of the cervix. Choice C (third) is incorrect as the third stage is the delivery of the placenta, and choice D (fourth) is incorrect as the fourth stage is the recovery period after childbirth.
2. Most cognitive aging research has focused on intellectual ________.
- A. stability
- B. gains
- C. competence
- D. deficits
Correct answer: D
Rationale: The correct answer is 'D: deficits.' Most cognitive aging research has indeed focused on deficits rather than stability, gains, or competence. Studies have consistently shown that deficits in processing speed and memory are common in aging individuals, making it a primary area of interest in research. Choices A, B, and C are incorrect because cognitive aging research primarily aims to understand and address deficits associated with aging rather than focusing on stability, gains, or overall competence.
3. When classmates are asked to rate each other's likability, __________ children get many positive votes, whereas __________ children are seldom mentioned.
- A. popular; neglected
- B. neglected; rejected
- C. popular; rejected
- D. controversial; neglected
Correct answer: A
Rationale: The correct answer is A: 'popular; neglected.' Popular children are well-liked by their peers, hence they receive many positive votes. Neglected children, on the other hand, are often overlooked or ignored, resulting in them being seldom mentioned. Choice B is incorrect because neglected and rejected have different meanings. Choice C is incorrect as popular and rejected do not align with the likability context provided in the question. Choice D is incorrect as controversial does not directly relate to likability in the context of the question.
4. A 20-week-old fetus can __________.
- A. be stimulated as well as irritated by sounds
- B. survive, if born early
- C. breathe without oxygen assistance, if born early
- D. control its own body temperature Answer: A Page Ref: 80 Skill Level: Understand Topic: Prenatal Development Difficulty Level: Moderate
Correct answer: A
Rationale: A 20-week-old fetus is able to be stimulated as well as irritated by sounds because by this stage of prenatal development, the fetus's auditory system is already well-developed. It can respond to external sounds and may even startle or move in reaction to loud noises.
5. In field experiments, researchers __________.
- A. selectively assign participants to treatment conditions in natural settings
- B. cannot use random assignment or manipulate treatment conditions
- C. randomly assign participants to treatment conditions in natural settings
- D. have stronger control over the treatment than in the laboratory
Correct answer: C
Rationale: In field experiments, researchers randomly assign participants to treatment conditions in natural settings. This method allows for a higher level of control over potential confounding variables compared to non-random assignment. Random assignment helps ensure that the groups being compared are comparable at the beginning of the study, which strengthens the internal validity of the research findings. Choice A is incorrect because selective assignment may introduce bias. Choice B is incorrect as researchers can use random assignment in field experiments. Choice D is incorrect because field experiments typically have less control over the treatment compared to laboratory experiments.
