1. 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.

2. Which statement describes a strength of naturalistic observation?

A. It reflects the participants' everyday lives.
B. It permits comparisons of participants' responses.
C. Great depth and breadth of information can be obtained in a short time.
D. It grants each participant an equal opportunity to display the behavior of interest.

Correct answer: A

Rationale: Naturalistic observation reflects the participants' everyday lives because it involves observing individuals in their natural environments without any manipulation. This allows researchers to see how people behave in real-world settings and can provide valuable insights into their typical behavior patterns. Choice B is incorrect because naturalistic observation focuses on observing behavior in its natural setting rather than comparing responses between participants. Choice C is incorrect as naturalistic observation tends to provide rich, qualitative data rather than a large amount of information in a short time. Choice D is incorrect because in naturalistic observation, participants are observed as they naturally behave, which may not always lead to an equal opportunity for all participants to display the behavior of interest.

3. The most rapid prenatal changes take place in the period of the __________.

A. zygote
B. blastocyst
C. embryo
D. fetus

Correct answer: C

Rationale: The correct answer is C: embryo. The most rapid prenatal changes occur during the embryo stage, which spans from approximately 2 to 8 weeks after conception. This period is crucial as major organs and systems of the body develop rapidly, laying the foundation for future growth and development. The zygote stage is the initial single-celled entity formed by the union of sperm and egg, while the blastocyst stage involves the cluster of cells resulting from the zygote dividing and growing. The fetus stage follows the embryo stage and focuses on refining and growing existing structures rather than rapid development. Therefore, the embryo stage is where the most significant and rapid changes take place in prenatal development.

4. What did John Bowlby believe?

A. Adults and more expert peers help children master culturally meaningful activities.
B. The infant-caregiver bond has lifelong consequences for human relationships.
C. Parents and infants are both instinctively attached to each other.
D. Attachment patterns are difficult to study in humans.

Correct answer: B

Rationale: John Bowlby believed that the infant-caregiver bond has lifelong consequences for human relationships. This is supported by his theory of attachment, where he emphasized the importance of early attachment experiences in shaping individuals' future relationships. Choice A is incorrect as it does not reflect Bowlby's main focus on attachment theory. Choice C is incorrect as Bowlby's theory suggests that attachment is more than just instinctual. Choice D is also incorrect as Bowlby's work actually paved the way for the study of attachment patterns in humans.

5. In mammals, including humans, the sense of smell __________.

A. does not become adultlike for several years
B. helps mothers and babies identify each other
C. is the least developed sense at birth
D. takes about four months to become adultlike

Correct answer: B

Rationale: The sense of smell in mammals, including humans, plays a crucial role in helping mothers and babies identify each other. This is important for initiating bonding and caregiving behaviors. Choice A is incorrect because the sense of smell is functional at birth and not entirely underdeveloped for several years. Choice C is incorrect as the sense of smell is actually well-developed at birth. Choice D is incorrect because the sense of smell is functional from birth and does not take several months to become adultlike.
