Human Growth and Development Final Exam Answers
1. Mothers who __________ have fewer birth complications and shorter labors.
- A. choose cesarean delivery
- B. give birth at home
- C. are supported by a trained companion during childbirth
- D. are administered epidural analgesia during childbirth
Correct answer: C
Rationale: According to research, mothers who are supported by a trained companion during childbirth have fewer birth complications and shorter labors. This support can reduce stress and anxiety levels, provide comfort and encouragement, and help the mother feel more in control during labor and delivery. Overall, having a trained companion present can contribute to a more positive childbirth experience for the mother. Choices A, B, and D are incorrect because they do not align with the research findings that specifically highlight the benefits of having a trained companion during childbirth.
2. 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.
3. When trying to soothe a crying baby, what technique do Western parents typically attempt first?
- A. Massaging the baby's body
- B. Offering a pacifier and a receiving blanket
- C. Playing recorded womb sounds or sounds of nature
- D. Lifting the baby to the shoulder and rocking or walking
Correct answer: D
Rationale: When Western parents aim to soothe a crying baby, the technique they usually try first is lifting the baby to the shoulder and rocking or walking. This method is effective because the motion and closeness provided by rocking or walking can help calm the baby and offer comfort. Choice A is incorrect as massaging the baby's body is not typically the first technique used. Choice B is incorrect as offering a pacifier and a receiving blanket may be tried after lifting the baby to the shoulder. Choice C is also incorrect as playing recorded sounds is usually not the initial technique attempted.
4. Which of the following best describes a sequential design?
- A. Does not address diversity in developmental outcomes.
- B. Permits researchers to check if cohort effects are operating.
- C. Is less efficient than a longitudinal design.
- D. Makes cross-sectional, but not longitudinal, comparisons.
Correct answer: B
Rationale: A sequential design permits researchers to check if cohort effects are operating. This design involves combining cross-sectional and longitudinal research, allowing for the comparison of different cohorts at different ages. By using this approach, researchers can determine if developmental changes observed are due to age or generation-specific factors. Therefore, a sequential design is valuable in addressing the potential influence of cohort effects on developmental outcomes. Choices A, C, and D are incorrect because a sequential design does not neglect diversity in developmental outcomes, is not necessarily less efficient than a longitudinal design, and can make both cross-sectional and longitudinal comparisons.
5. Taking tests and answering questionnaires are examples of __________.
- A. research designs
- B. theories
- C. hypotheses
- D. research methods
Correct answer: D
Rationale: Taking tests and answering questionnaires are examples of research methods. Research methods refer to the specific approaches used in conducting research, such as collecting data, analyzing information, and drawing conclusions. In this case, tests and questionnaires are tools used to gather information and data for research purposes, making them examples of research methods. Choices A, B, and C are incorrect because research designs refer to the overall structure and plan of a study, theories are explanations developed through research and observation, and hypotheses are specific predictions or statements that can be tested through research.
