Human Growth and Development Final Exam Answers
1. Which statement provides an example of an age-graded influence?
- A. Paul learned to play the violin at a young age.
- B. Jack enjoys hiking in the mountains.
- C. Sarah prefers reading mystery novels.
- D. Alex excels in mathematics.
Correct answer: A
Rationale: The corrected statement 'Paul learned to play the violin at a young age' provides an example of an age-graded influence. This is because learning to play the violin is a behavior that is typical or expected at a certain age, reflecting how age influences individuals' experiences and development. In contrast, choices B, C, and D do not directly relate to age-graded influences. Jack's enjoyment of hiking, Sarah's preference for reading mystery novels, and Alex's proficiency in mathematics are not inherently tied to age-related developmental influences.
2. In an experiment, the independent variable __________.
- A. is the one the investigator expects to be influenced by another variable
- B. is the one the investigator expects to cause changes in another variable
- C. cannot be manipulated or controlled by the researcher
- D. is the number that describes how two measures are associated with each other
Correct answer: B
Rationale: In an experiment, the independent variable is the one that the investigator expects to cause changes in another variable. It is the factor that is deliberately manipulated or changed by the researcher to observe its effects on the dependent variable. The purpose of manipulating the independent variable is to study its impact on the outcome, allowing researchers to establish cause-and-effect relationships in their investigations. Choice A is incorrect because the independent variable is not influenced but rather influences another variable. Choice C is incorrect as the independent variable is intentionally manipulated by the researcher. Choice D is incorrect as it refers to a different concept unrelated to the independent variable in an experiment.
3. What is one limitation of the ethnographic method?
- A. Investigators' cultural values sometimes lead them to misinterpret what they see.
- B. It provides little information on how children and adults actually behave.
- C. It relies on unobtrusive techniques, such as surveillance cameras and one-way mirrors.
- D. It provides little information about the reasoning behind participants' responses.
Correct answer: A
Rationale: The limitation of the ethnographic method is that investigators' cultural values sometimes lead them to misinterpret what they see. This can introduce bias into the observations and potentially impact the accuracy of the findings. It is important for researchers to be aware of their own biases and strive to minimize their influence when conducting ethnographic studies. Choice B is incorrect because ethnographic methods actually aim to provide rich information on how individuals behave within their cultural contexts. Choice C is incorrect as ethnographic methods typically involve direct observation and participation rather than unobtrusive techniques like surveillance cameras. Choice D is incorrect because one of the strengths of ethnographic research is its ability to uncover the reasoning behind participants' responses by immersing the researcher in the cultural setting.
4. When Mateo was born prematurely to Yvonne, a cocaine addict, what can his caregivers expect?
- A. He will be very attentive to the environment
- B. His cries will be abnormally shrill and piercing
- C. He will overcome the harmful effects of drug exposure by age 3
- D. His motor development will be especially rapid during the first year
Correct answer: B
Rationale: Mateo, being born prematurely to a cocaine-addicted mother, is at risk for several health issues. One common effect of prenatal drug exposure is a higher likelihood of sensory and regulatory problems, such as having abnormally shrill and piercing cries. This is a potential outcome that Mateo's caregivers can expect due to his circumstances. Choice A is incorrect as there is no direct correlation between being born prematurely to a cocaine-addicted mother and being very attentive to the environment. Choice C is incorrect as overcoming harmful effects of drug exposure by age 3 is overly optimistic and may not be the case for all children exposed to drugs prenatally. Choice D is incorrect as rapid motor development is not typically associated with prenatal drug exposure.
5. The more alcohol a woman consumes during pregnancy, the __________.
- A. higher the birth weight of the child
- B. greater the likelihood of ARND instead of FAS or p-FAS
- C. poorer the child's achievement scores in the school years
- D. greater the child's speed of information processing
Correct answer: C
Rationale: The correct answer is C: 'poorer the child's achievement scores in the school years.' Prenatal exposure to alcohol has been linked to a range of cognitive and behavioral difficulties, including lower academic achievement in children. These difficulties may manifest as poor achievement scores in later school years. Choices A, B, and D are incorrect because alcohol consumption during pregnancy is not associated with higher birth weight of the child, the likelihood of ARND instead of FAS or p-FAS, or greater speed of information processing in the child.
