Human Growth and Development Final Exam
1. Shamona, a pregnant mother in Flint, Michigan, is concerned about the drinking water, which shows high levels of lead. Shamona should know that high levels of prenatal lead exposure are related to __________.
- A. facial abnormalities and heart defects
- B. defects of the genitals and urinary tract
- C. low birth weight and brain damage
- D. a variety of childhood cancers
Correct answer: C
Rationale: High levels of prenatal lead exposure are related to low birth weight and brain damage. Lead exposure during pregnancy can have harmful effects on the developing fetus, leading to complications such as decreased birth weight and potential long-term brain damage. Choices A, B, and D are incorrect because they do not directly correlate with the known effects of prenatal lead exposure. While lead exposure can indeed cause a variety of health issues, such as heart defects and urinary tract problems, the primary concerns related to prenatal exposure are low birth weight and brain damage.
2. Dr. Anderson wants to conduct a study to determine the cause-and-effect relationship between domestic violence and anger in children. Dr. Anderson should use a(n) __________ design.
- A. structured
- B. observational
- C. correlational
- D. experimental
Correct answer: D
Rationale: Dr. Anderson should use an experimental design to determine the cause-and-effect relationship between domestic violence and anger in children. In an experimental design, the researcher manipulates the independent variable (in this case, exposure to domestic violence) to observe its effect on the dependent variable (anger in children). This design allows for the establishment of a cause-and-effect relationship by controlling for other variables that may influence the outcomes. Observational design (Choice B) involves observing subjects in their natural environment without interference, correlational design (Choice C) examines the relationship between variables without manipulating them, and structured design (Choice A) typically refers to a study with predetermined procedures and data collection methods, which may not be suitable for establishing cause-and-effect relationships.
3. What did Ivan Pavlov discover?
- A. observational learning
- B. classical conditioning
- C. the ego's positive contributions to development
- D. the clinical method
Correct answer: B
Rationale: Ivan Pavlov discovered classical conditioning. This is a form of learning in which a neutral stimulus becomes associated with a meaningful stimulus and acquires the capacity to elicit a similar response. Pavlov's famous experiment with dogs, where he conditioned them to salivate at the sound of a bell, demonstrated this principle. Choices A, C, and D are incorrect because Pavlov's work primarily focused on classical conditioning, not observational learning, ego contributions to development, or the clinical method.
4. How does physical activity impact mental health?
- A. Reduces anxiety and depression
- B. Improves mood, but decreases alertness
- C. Decreases mood, alertness, and energy
- D. Decreases neural activity in the cerebral cortex
Correct answer: A
Rationale: Physical activity is known to have a positive impact on mental health by reducing symptoms of anxiety and depression. Choice B is incorrect because physical activity generally improves both mood and alertness. Choice C is incorrect as physical activity tends to increase mood, alertness, and energy levels. Choice D is incorrect as physical activity actually increases neural activity in the cerebral cortex, which is associated with improved cognitive function and mental well-being.
5. In egalitarian marriages, __________.
- A. there is a clear division of roles
- B. partners share power and authority
- C. the husband is the head of the household
- D. the wife is responsible for family economic well-being
Correct answer: B
Rationale: In egalitarian marriages, the correct answer is B - partners share power and authority. This type of marriage promotes equality and balance, where both spouses have an equal say in decision-making and share responsibilities. Choice A is incorrect because egalitarian marriages aim to reduce traditional role divisions. Choice C is incorrect as it suggests a patriarchal structure, which is contrary to the principles of egalitarianism. Choice D is incorrect as it assigns a specific financial role based on gender, which goes against the idea of equal sharing in all aspects of the marriage.
