1. In the __________ period, teratogens rarely have any impact.

• A. germinal
• B. embryonic
• C. fetal
• D. prenatal

Correct answer: A

Rationale: In the germinal period of prenatal development, which lasts for about the first two weeks after fertilization, the developing organism is a zygote that has not yet implanted in the uterus. During this period, teratogens rarely have any impact because essential implantation and early cellular division processes are occurring. Teratogens are more likely to have significant effects during the later embryonic and fetal periods of development. Therefore, the correct answer is A. Choice B, embryonic period, is incorrect because teratogens have a higher likelihood of impacting development during this period. Choice C, fetal period, is also incorrect as teratogens can impact development during this stage as well. Choice D, prenatal, is a broad term encompassing the entire period of development from conception to birth and is not a specific developmental stage where teratogens have a minimal impact.

2. 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.

3. Which statement about prenatal rubella is true?

• A. The greatest damage occurs when rubella strikes during the fetal period.
• B. The organ damage inflicted by prenatal rubella can lead to lifelong health problems. Copyright © 2018 Laura E. Berk. All Rights Reserved. 15 Test Bank for Berk, Development Through the Lifespan, 7e
• C. Routine vaccination has made new rubella outbreaks extremely rare worldwide.
• D. Infection during the embryonic period is less harmful than during other prenatal periods. Answer: B Page Ref: 86‒87 Skill Level: Understand known or suspected teratogens. Topic: Prenatal Environmental Influences Difficulty Level: Moderate

Correct answer: B

Rationale: The statement that the organ damage inflicted by prenatal rubella can lead to lifelong health problems is true. Rubella infection during pregnancy can cause serious harm to the developing fetus, including organ damage, deafness, heart defects, and intellectual disabilities. This highlights the importance of prevention and vaccination to protect both pregnant women and their unborn babies from the harmful effects of rubella.

4. Today, Albert Bandura's theory stresses the importance of __________.

• A. behavior modification
• B. punishment
• C. cognition
• D. reinforcement

Correct answer: C

Rationale: Albert Bandura's theory stresses the importance of cognition. Bandura's Social Learning Theory emphasizes the role of cognitive processes in learning and behavior, including the influence of observation, modeling, and mental representations. This theory highlights how individuals learn through observation and imitation of others, as well as their own thought processes and beliefs. Choices A, B, and D are incorrect because while behavior modification, punishment, and reinforcement are aspects related to learning theories, they are not the primary focus of Bandura's theory, which revolves around cognition and social learning.

5. Which statement is supported by research on newborn taste preferences?

• A. Newborns cannot distinguish basic tastes.
• B. Not until 4 months do babies prefer a salty taste to plain water.
• C. Newborns prefer the taste of formula to breast milk.
• D. Unlike adults, babies relax their facial muscles in response to sour tastes.

Correct answer: B

Rationale: Research on newborn taste preferences has found that not until around 4 months of age do babies start to show a preference for a salty taste over plain water. This indicates that newborns do have some ability to distinguish tastes, contrary to the statement in option A. The statement in option C that newborns prefer the taste of formula to breast milk is not supported by research on newborn taste preferences. Option D, stating that babies relax their facial muscles in response to sour tastes, is also not a supported statement regarding newborn taste preferences.
