Growth and Development Exam
1. What is one strength of the cross-sectional design?
- A. It provides evidence about individual trends.
- B. It cannot be threatened by cohort effects.
- C. It is not plagued with dropout or practice effects.
- D. It permits longitudinal comparisons. Answer: C Page Ref: 34 Skill Level: Understand Topic: Studying Development Difficulty Level: Moderate
Correct answer: C
Rationale: One strength of the cross-sectional design is that it is not plagued with dropout or practice effects. This is because cross-sectional studies assess different individuals at the same point in time, eliminating the risk of participants dropping out or improving due to repeated measures.
2. During the second month of pregnancy, __________.
- A. the umbilical cord first appears as a primitive body stalk
- B. touch sensitivity extends to most of the body
- C. the heart develops separate chambers
- D. the heartbeat can be heard through a stethoscope
Correct answer: C
Rationale: During the second month of pregnancy, the heart of the developing fetus begins to develop separate chambers, forming the structure necessary for a fully functioning heart. This is a significant milestone in the prenatal development process. Choices A, B, and D are incorrect because the appearance of the umbilical cord as a primitive body stalk typically occurs around week 5-6, touch sensitivity extending to most of the body is more characteristic of the end of the second trimester, and the heartbeat is usually detectable through a stethoscope around the 18th to 20th week of pregnancy, not during the second month.
3. 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.
4. Which statement about interventions that support parents and preterm infants is true?
- A. Preterm infants whose parents receive coaching show no gains in mental test performance.
- B. Babies who are both preterm and economically disadvantaged require long-term, intensive intervention.
- C. For economically disadvantaged parents of preterm infants, just a few sessions of coaching are required.
- D. Even for parents with adequate economic and personal resources, long-term, intensive intervention is necessary. Answer: B Page Ref: 100 Skill Level: Understand Copyright © 2018 Laura E. Berk. All Rights Reserved. 29 Test Bank for Berk, Development Through the Lifespan, 7e interventions. Topic: Preterm and Low-Birth-Weight Infants Difficulty Level: Moderate
Correct answer: B
Rationale: Babies who are both preterm and economically disadvantaged typically require long-term, intensive intervention. This is because the combination of being born preterm and being economically disadvantaged can pose significant challenges for the infant's development. Providing ongoing support and interventions can help address these challenges and promote healthy development in these infants.
5. 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.
