Human Growth and Development Exam 1

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. The embryonic disk __________.

A. becomes the new organism
B. is the outer ring of cells on a blastocyst
C. has a good chance of survival outside the womb
D. is a protective membrane that surrounds the amnion Answer: A Page Ref: 77 Skill Level: Understand Topic: Prenatal Development Difficulty Level: Moderate

Correct answer: A

Rationale: The embryonic disk becomes the new organism. It is a cluster of cells within the blastocyst that will develop into the fetus during the early stages of prenatal development. This cluster of cells is responsible for giving rise to all the tissues and organs of the developing organism.

3. In a cross-sectional design, researchers study __________.

A. the same group of participants repeatedly at different ages
B. groups of participants differing in age at the same point in time
C. groups of participants of the same age in different years
D. participants of the same age at the same point in time

Correct answer: B

Rationale: In a cross-sectional design, researchers study groups of participants differing in age at the same point in time. This design allows researchers to compare different age groups simultaneously, providing valuable insight into age-related differences without the need to track the same group over time. Choice A is incorrect because it describes a longitudinal design where the same group is followed over time. Choice C is incorrect as it involves different groups of the same age studied at different times. Choice D is incorrect as it does not capture the essence of a cross-sectional design, which involves studying groups of different ages at the same point in time.

4. According to __________ theory, children learn primarily through modeling.

A. reinforcement
B. operant conditioning
C. social learning
D. classical conditioning

Correct answer: C

Rationale: According to social learning theory, children primarily learn through modeling, observation, and imitation of others. This theory emphasizes the importance of cognitive processes in learning, as opposed to only focusing on direct reinforcement or punishment. Social learning theory was developed by psychologist Albert Bandura and is a key theory in the field of child development. Choice A, reinforcement, is incorrect as it refers to the process of strengthening a behavior through rewards or punishments. Choice B, operant conditioning, is also incorrect as it is a learning process that involves reinforcement and punishment to shape behavior. Choice D, classical conditioning, is not the correct answer as it involves learning through association between stimuli.

5. Which mother is most likely to have had inadequate prenatal care?

A. Lupe, age 25
B. Marissa, age 32
C. Rotunda, age 16
D. Janette, age 40

Correct answer: C

Rationale: Rotunda, age 16, is the most likely to have had inadequate prenatal care due to her young age and possibly limited access to healthcare resources and support. Adolescents are at higher risk for inadequate prenatal care compared to older mothers due to various factors such as lack of awareness, financial constraints, and inconsistent health behaviors. Young mothers may face challenges in seeking proper prenatal care due to reasons like lack of knowledge, fear of judgment, or limited financial means. Older mothers like Lupe, Marissa, and Janette are less likely to have inadequate prenatal care compared to a younger mother like Rotunda, as they may have more access to resources, experience, and support systems.
