Growth and Development Exam
1. Bernadette, a participant in a longitudinal study, became quite familiar with the test over time and, as a result, her performance improved. This limitation of longitudinal research is known as __________. Copyright © 2018 Laura E. Berk. All Rights Reserved. 34 Test Bank for Berk, Development Through the Lifespan, 7e
- A. biased sampling
- B. practice effects
- C. random assignment
- D. cohort effects Answer: B Page Ref: 35 Skill Level: Apply Topic: Studying Development Difficulty Level: Moderate
Correct answer: B
Rationale: Practice effects refer to the phenomenon where participants in a longitudinal study show improvement in test performance over time due to becoming familiar with the tasks or test materials. This can be considered a limitation as it may distort the results by showing an artificial improvement rather than a true developmental change.
2. Three-month-old Jefferson will probably listen longer to __________ than to __________.
- A. pure tones; voices
- B. pure tones; noises
- C. human speech; nonspeech sounds
- D. a foreign language; his native language
Correct answer: C
Rationale: Three-month-old Jefferson will likely listen longer to human speech compared to nonspeech sounds because infants have a natural preference for speech sounds. This preference is believed to be attributed to their biological readiness to learn language and communicate with others. Choice A is incorrect because voices are a form of human speech, which is preferred over pure tones. Choice B is incorrect as noises do not necessarily engage infants' attention as effectively as human speech. Choice D is incorrect because Jefferson is more likely to listen longer to his native language rather than a foreign language at this early age.
3. Which individual is most likely to experience the greatest percentage of REM sleep?
- A. Sammy, a preschool child
- B. Jake, a full-term newborn
- C. Sarah, a teenager
- D. Cheryl, a preterm newborn Answer: D Page Ref: 104 Copyright © 2018 Laura E. Berk. All Rights Reserved. 32 Test Bank for Berk, Development Through the Lifespan, 7e Skill Level: Apply Topic: The Newborn Baby’s Capacities Difficulty Level: Moderate
Correct answer: D
Rationale: Preterm newborns, like Cheryl, experience a higher percentage of REM sleep compared to full-term newborns. This is because REM sleep plays a critical role in brain development, and preterm infants have an increased need for brain development due to their early arrival. Therefore, Cheryl, as a preterm newborn, is most likely to experience the greatest percentage of REM sleep among the individuals listed.
4. Pregnant women are wise to avoid eating __________, which are heavily contaminated with __________.
- A. long-lived predatory fish; mercury
- B. freshwater fish; lead
- C. long-lived predatory fish; polychlorinated biphenyls
- D. freshwater fish; radiation
Correct answer: A
Rationale: Pregnant women are wise to avoid eating long-lived predatory fish, which are heavily contaminated with mercury. Mercury is a known teratogen, meaning it can negatively impact the development of the fetus and lead to birth defects. It is recommended that pregnant women choose fish with lower levels of mercury to reduce potential risks to the baby's health. Choices B, C, and D are incorrect because lead, polychlorinated biphenyls, and radiation are not typically found in fish at levels that pose significant risks to pregnant women and the developing fetus.
5. 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.
