Human Growth and Development Exam 1
1. During pregnancy, the placenta __________.
- A. forms in the second trimester of pregnancy
- B. encloses the developing organism in amniotic fluid
- C. contains one large vein that delivers nutrients to the embryo
- D. delivers food and oxygen to the developing organism
Correct answer: D
Rationale: The placenta delivers food and oxygen to the developing organism during pregnancy. It is a temporary organ that forms in the first trimester of pregnancy. Choice A is incorrect as the placenta forms in the first trimester, not the second trimester. Choice B is incorrect as the amniotic sac, not the placenta, encloses the developing organism in amniotic fluid. Choice C is incorrect as the placenta contains blood vessels (arteries and veins) that deliver nutrients to the embryo, not just one large vein.
2. Dr. Kostel believes that development takes place in stages. This belief is consistent with the __________ perspective.
- A. nurture
- B. continuous
- C. discontinuous
- D. nature
Correct answer: C
Rationale: Dr. Kostel's belief in stage-based development aligns with the discontinuous perspective, which sees development as a series of distinct stages. The continuous perspective (choice B) suggests development as a smooth and gradual process without distinct stages. The nature perspective (choice D) focuses on genetic and hereditary influences on development. The nurture perspective (choice A) emphasizes the impact of environment and upbringing on development, which is not directly related to the belief in stage-based development.
3. In a structured observation, each participant has an equal opportunity to display the behavior of interest because the researcher designs a specific set of conditions or tasks for all participants to engage in, providing a standardized environment for observation.
- A. clinical interview
- B. naturalistic observation
- C. structured observation
- D. case study
Correct answer: C
Rationale: In a structured observation, each participant has an equal opportunity to display the behavior of interest because the researcher designs a specific set of conditions or tasks for all participants to engage in, providing a standardized environment for observation. This allows for fair and equitable observations across all participants, ensuring that each individual has the same opportunities to exhibit the behavior being studied. Choice A, clinical interview, typically involves a one-on-one interaction between a researcher and a participant focusing on collecting information through questions and answers, not providing equal opportunities for behavior display. Choice B, naturalistic observation, involves observing individuals in their natural environment without intervention or manipulation of conditions, which may not always ensure equal opportunities for behavior display. Choice D, case study, focuses on in-depth analysis of a single individual or a small group, providing detailed information but not necessarily ensuring equal opportunities for behavior display among participants.
4. Many theorists believe that behaviorism and social learning theory ________.
- A. overemphasize the plasticity of cognitive development
- B. overestimate people's contributions to their own development
- C. offer too narrow a view of important environmental influences
- D. overemphasize each individual's unique life history
Correct answer: C
Rationale: Many theorists believe that behaviorism and social learning theory offer too narrow a view of important environmental influences. This is because they focus mainly on observable behaviors and external factors, neglecting the role of internal cognitive processes and individual differences in shaping development. Choices A, B, and D are incorrect because behaviorism and social learning theory do not specifically emphasize the plasticity of cognitive development, overestimate people's contributions to their own development, or overemphasize each individual's unique life history. Instead, they are criticized for providing a limited perspective by focusing predominantly on external stimuli and behaviors.
5. __________ supplementation early in pregnancy reduces the risk of abnormalities of the neural tube, the circulatory system, and the urinary tract.
- A. Vitamin A
- B. Folic acid
- C. Vitamin D
- D. Vitamin C
Correct answer: B
Rationale: Folic acid supplementation early in pregnancy is crucial as it reduces the risk of abnormalities in the developing fetus. It is specifically known to prevent issues related to the neural tube, circulatory system, and urinary tract. Vitamin A, Vitamin D, and Vitamin C do not play the same role as folic acid in preventing these specific birth defects, making them incorrect choices.
