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. Which research method was borrowed from the field of anthropology?

A. ethnography
B. clinical interview
C. structured interview
D. systematic observation

Correct answer: A

Rationale: The correct answer is A: ethnography. Ethnography is a research method borrowed from the field of anthropology. It involves observing and documenting behaviors and interactions in a naturalistic setting. This method allows researchers to gain insight into the cultural context and practices of a group through direct observation and participation. Choices B, C, and D are incorrect because clinical interviews, structured interviews, and systematic observations are research methods used in different contexts and fields, not borrowed specifically from anthropology.

3. According to operant conditioning theory, __________.

A. the frequency of a behavior can be increased through punishment, such as disapproval
B. normal development must be understood in relation to each culture's life situation
C. the id develops as parents insist that children conform to the values of society
D. the frequency of a behavior can be increased by following it with a wide variety of reinforcers

Correct answer: D

Rationale: According to operant conditioning theory, the frequency of a behavior can be increased by following it with a wide variety of reinforcers. In operant conditioning, behaviors are shaped through reinforcement, which can be positive (rewarding) or negative (removal of something unpleasant). By providing reinforcement following a behavior, the likelihood of that behavior occurring again in the future is increased. This supports the notion that the frequency of a behavior can be increased by using reinforcers in operant conditioning. Choices A, B, and C are incorrect because operant conditioning focuses on the relationship between behavior and its consequences through reinforcement (positive or negative) to increase the likelihood of the behavior recurring, rather than punishment, cultural influences, or the development of the id based on societal values.

4. Longitudinal research can identify common patterns as well as individual differences in development because the investigator __________.

A. studies groups of participants differing in age at the same point in time
B. randomly assigns participants to treatment conditions
C. tracks the performance of each person over time
D. conducts quasi-experiments, comparing conditions that already exist

Correct answer: C

Rationale: Longitudinal research involves tracking the performance of each person over time. By doing so, researchers can observe common patterns in development among a group of individuals and also identify individual differences in how each person progresses over time. This methodology allows researchers to gather data on the same individuals repeatedly, offering insights into how development unfolds over the lifespan. Choices A, B, and D are incorrect because longitudinal research focuses on observing individuals over time rather than studying groups at a single point, randomly assigning participants to treatments, or conducting quasi-experiments.

5. Men with even tiny amounts of dioxin in their bloodstream father __________.

A. nearly twice as many girls as boys
B. nearly three times as many boys as girls
C. more twins and triplets than unaffected men
D. fewer children than unaffected men

Correct answer: A

Rationale: Men with even tiny amounts of dioxin in their bloodstream father nearly twice as many girls as boys. This is due to the impact of dioxin exposure on sperm cells, leading to a skewed ratio of female to male offspring. Choice B is incorrect as the question specifically mentions that men father more girls than boys. Choice C is incorrect as dioxin exposure does not necessarily lead to more twins and triplets. Choice D is incorrect as men with dioxin in their bloodstream father more girls, not fewer children overall.
