Human Growth and Development Final Exam
1. Lanugo ________.
- A. permits food and oxygen to reach the organism
- B. provides the fetus a cushion against jolts caused by the mother's movements
- C. helps regulate the fetus's body temperature
- D. helps the vernix stick to the skin
Correct answer: D
Rationale: Lanugo helps the vernix stick to the skin. Vernix is a waxy substance that covers the fetus's skin during pregnancy. Lanugo is a fine, downy hair that helps to anchor the vernix to the skin, providing protection and nourishment to the developing fetus. Choices A, B, and C are incorrect as they do not accurately describe the role of lanugo in prenatal development.
2. According to the cognitive perspective of perceptual development, what do babies do?
- A. are blank slates
- B. impose meaning on what they perceive
- C. actively search for discontinuous stimuli
- D. seek variant features in the environment
Correct answer: B
Rationale: According to the cognitive perspective of perceptual development, babies impose meaning on what they perceive. This means that babies actively interpret and make sense of the stimuli they encounter. Choice A is incorrect because babies are not seen as blank slates in this context; they actively engage with their environment. Choice C is incorrect as babies do not necessarily search for discontinuous stimuli, but rather interpret what they perceive. Choice D is incorrect as seeking variant features in the environment is not a core concept of the cognitive perspective of perceptual development.
3. Recent evidence suggests that paternal alcohol use around the time of conception __________.
- A. can alter gene expression
- B. can cause fetal alcohol syndrome
- C. is linked to blood vessel abnormalities
- D. has no negative effect on the developing organism
Correct answer: A
Rationale: Recent evidence suggests that paternal alcohol use around the time of conception can alter gene expression. This means that paternal alcohol consumption can potentially impact the genes and genetic materials passed on to offspring, affecting their development and health. Choice B is incorrect because fetal alcohol syndrome is typically associated with maternal alcohol consumption during pregnancy, not paternal alcohol use around conception. Choice C is incorrect as there is no direct link between paternal alcohol use and blood vessel abnormalities. Choice D is incorrect as paternal alcohol use can indeed have negative effects on the developing organism, particularly through altering gene expression.
4. What is one limitation of the ethnographic method?
- A. Investigators' cultural values sometimes lead them to misinterpret what they see.
- B. It provides little information on how children and adults actually behave.
- C. It relies on unobtrusive techniques, such as surveillance cameras and one-way mirrors.
- D. It provides little information about the reasoning behind participants' responses.
Correct answer: A
Rationale: The limitation of the ethnographic method is that investigators' cultural values sometimes lead them to misinterpret what they see. This can introduce bias into the observations and potentially impact the accuracy of the findings. It is important for researchers to be aware of their own biases and strive to minimize their influence when conducting ethnographic studies. Choice B is incorrect because ethnographic methods actually aim to provide rich information on how individuals behave within their cultural contexts. Choice C is incorrect as ethnographic methods typically involve direct observation and participation rather than unobtrusive techniques like surveillance cameras. Choice D is incorrect because one of the strengths of ethnographic research is its ability to uncover the reasoning behind participants' responses by immersing the researcher in the cultural setting.
5. Dr. Rizvi studies the relationship between changes in the brain and the developing person's cognitive processing and behavior patterns. She is part of a group of researchers from the fields of psychology, biology, neuroscience, and medicine. This approach to development is known as __________.
- A. behaviorism
- B. cognitive-development theory
- C. the information-processing approach
- D. developmental cognitive neuroscience
Correct answer: D
Rationale: Dr. Rizvi's approach to development, involving studying the relationship between changes in the brain and cognitive processing and behavior patterns, aligns with developmental cognitive neuroscience. This field combines research from various disciplines to understand how brain development influences cognitive processes and behaviors. Choice A, behaviorism, focuses on observable behaviors influenced by external stimuli. Choice B, cognitive-development theory, emphasizes cognitive growth stages. Choice C, the information-processing approach, centers on how individuals perceive, store, and retrieve information.
