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. Which statement about prenatal marijuana exposure is true?

• A. It is linked to impulsivity and overactivity.
• B. Lasting consequences are well-established.
• C. Studies show no negative effects of exposure.
• D. It is linked to an array of physical malformations.

Correct answer: A

Rationale: The correct answer is A: 'It is linked to impulsivity and overactivity.' Prenatal marijuana exposure has been associated with impulsivity and overactivity in children based on research findings. However, lasting consequences of prenatal marijuana exposure are not as well-established compared to other teratogens. Choice B is incorrect because lasting consequences are not firmly established. Choice C is incorrect because studies have shown negative effects of prenatal marijuana exposure. Choice D is incorrect as prenatal marijuana exposure is not primarily linked to physical malformations.

3. Which of the following is the best available predictor of infant survival and healthy development?

• A. Birth length
• B. Combined Apgar score
• C. Delivery date
• D. Birth weight

Correct answer: D

Rationale: The correct answer is 'Birth weight.' Birth weight is a crucial indicator of an infant's chances of survival and well-being. Low birth weight is associated with various health risks and developmental challenges. Birth length (choice A) is not as significant in predicting infant outcomes as birth weight. The Combined Apgar score (choice B) is a measure of the newborn's health status at birth, not a predictor of long-term survival and development. Delivery date (choice C) is important for determining gestational age but is not as directly related to infant survival and healthy development as birth weight.

4. As a generation, the baby boomers are __________ than any previous mid- or late-life cohort.

• A. healthier, but less educated
• B. more educated, but less wealthy
• C. more self-focused, but less healthy
• D. healthier, better educated, and financially better off Answer: D Page Ref: 13 Box: CULTURAL INFLUENCES: The Baby Boomers Reshape the Life Course Skill Level: Remember Topic: The Lifespan Perspective: A Balanced Point of View Difficulty Level: Moderate

Correct answer: D

Rationale: The baby boomers are healthier, better educated, and financially better off than any previous mid- or late-life cohort. This generation has generally enjoyed higher levels of education, advancements in healthcare, and increased economic opportunities, leading to improved overall well-being compared to earlier generations.

5. 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.
