1. Which of the following best describes a sequential design?

• A. Does not address diversity in developmental outcomes.
• B. Permits researchers to check if cohort effects are operating.
• C. Is less efficient than a longitudinal design.
• D. Makes cross-sectional, but not longitudinal, comparisons.

Correct answer: B

Rationale: A sequential design permits researchers to check if cohort effects are operating. This design involves combining cross-sectional and longitudinal research, allowing for the comparison of different cohorts at different ages. By using this approach, researchers can determine if developmental changes observed are due to age or generation-specific factors. Therefore, a sequential design is valuable in addressing the potential influence of cohort effects on developmental outcomes. Choices A, C, and D are incorrect because a sequential design does not neglect diversity in developmental outcomes, is not necessarily less efficient than a longitudinal design, and can make both cross-sectional and longitudinal comparisons.

2. According to Piaget, in which stage of cognitive development is four-year-old R’Monte who engages in make-believe play by stirring beads in a bowl and saying, “Soup is ready!”?

• A. sensorimotor
• B. preoperational
• C. concrete operational
• D. sociocultural

Correct answer: B

Rationale: According to Piaget's theory of cognitive development, four-year-old R’Monte's engagement in make-believe play, such as pretending to stir beads in a bowl and creating imaginary soup, indicates that he is in the preoperational stage of cognitive development. This stage is characterized by symbolic thinking, pretend play, language development, and egocentrism. Choice A, sensorimotor, is incorrect as this stage occurs in infancy and focuses on sensory experiences and object permanence. Choice C, concrete operational, is incorrect as this stage occurs around ages 7-11 and involves logical reasoning about concrete events. Choice D, sociocultural, is incorrect as it does not correspond to Piaget's stages of cognitive development.

3. Unlike adults, newborn babies __________.

• A. have a limited sense of smell
• B. see nearby objects most clearly
• C. prefer unfamiliar voices to familiar ones
• D. see unclearly across a wide range of distances

Correct answer: B

Rationale: Unlike adults, newborn babies see nearby objects most clearly. This is due to the fact that newborns have a limited ability to focus their eyes on objects that are farther away. Their visual acuity is not fully developed at birth, leading to clearer vision of objects situated at a close distance. Choice A is incorrect because newborn babies have a well-developed sense of smell. Choice C is incorrect as newborns typically show a preference for familiar voices, such as their mother's voice. Choice D is incorrect as newborns do not see unclearly across a wide range of distances; rather, their vision is clearer for nearby objects.

4. Liz is 36 weeks pregnant. A rise in her baby's heart rate is probably followed within five seconds by __________.

• A. a burst of motor activity
• B. a period of sleep
• C. a rise in Liz's heart rate
• D. a drop in Liz's body temperature

Correct answer: A

Rationale: A rise in the baby's heart rate during pregnancy is usually followed within five seconds by a burst of motor activity. This indicates that the baby is responding to stimuli and is an important sign of healthy fetal development. A period of sleep, a rise in Liz's heart rate, or a drop in Liz's body temperature are not typically immediate responses to changes in the baby's heart rate. Sleep is less likely to be a direct response to changes in heart rate, Liz's heart rate is independent of the baby's heart rate changes, and a drop in Liz's body temperature is not a common immediate response to fetal heart rate changes.

5. Maryann is pregnant and works in a smoke-filled environment. What can you tell her about passive smoking?

• A. The negative effects of smoking are only evident in children born to heavy smokers.
• B. Passive smoking is related to low birth weight, infant death, and childhood respiratory illnesses.
• C. Smoke-filled environments are harmful to expectant mothers, but not to their unborn children.
• D. The effects of passive smoking are not yet known.

Correct answer: B

Rationale: Passive smoking, also known as secondhand smoke, can have harmful effects on pregnancies. Research has shown that exposure to smoke-filled environments during pregnancy is linked to low birth weight, infant death, and childhood respiratory illnesses. Pregnant women should avoid exposure to secondhand smoke to protect the health of their unborn babies. Choice A is incorrect because passive smoking affects both the mother and the unborn child, not just children born to heavy smokers. Choice C is incorrect as it underestimates the risks of smoke-filled environments on unborn children. Choice D is incorrect as research has already established the harmful effects of passive smoking on pregnancies.
