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. Babies who spend more time alert are likely to have __________.
- A. parents who feel incompetent
- B. a slight advantage in mental development
- C. a big disadvantage in social development
- D. parents who must exert great effort to soothe them
Correct answer: B
Rationale: Babies who spend more time alert are likely to have a slight advantage in mental development. Being alert allows babies to engage with their surroundings, explore, and learn, which can contribute to their cognitive development. This is different from social development, which is more related to interactions with others, and not necessarily impacted by the amount of alertness a baby displays. Choices A, C, and D are incorrect because there is no direct correlation between a baby's alertness and their parents' feelings of incompetence, a big disadvantage in social development, or the effort parents need to soothe them.
3. Dr. George predicted that positive reinforcement would increase prosocial behavior in preschoolers. Dr. George's prediction is an example of a __________.
- A. theory
- B. research question
- C. hypothesis
- D. research design
Correct answer: C
Rationale: Dr. George's prediction that positive reinforcement would increase prosocial behavior in preschoolers is an example of a hypothesis. A hypothesis is a specific, testable prediction about the relationship between variables based on existing knowledge or theories. In this case, Dr. George is making a prediction about the effect of positive reinforcement on prosocial behavior, which can be tested through research. Choice A, 'theory,' is incorrect because a theory is a broader explanation that integrates a range of findings and observations. Choice B, 'research question,' is incorrect as it refers to an inquiry that asks about the relationship between variables but lacks the specificity and testability of a hypothesis. Choice D, 'research design,' is incorrect as it pertains to the overall strategy or plan for conducting a research study, not the specific prediction Dr. George made.
4. As school-age children move into adolescence, self-concept is increasingly vested in feedback from __________.
- A. close friends
- B. family members
- C. younger children
- D. the inner self
Correct answer: A
Rationale: During adolescence, individuals start to rely more on feedback from close friends to develop their self-concept. Close friends play a significant role during this transitional period as they provide peer validation, support, and influence. Family members, although important, may not hold the same level of influence on self-concept during adolescence as close friends do. Younger children are unlikely to provide the necessary feedback and validation needed during this developmental stage. While self-reflection and understanding the inner self are vital for personal growth, during adolescence, external feedback from close friends tends to have a more pronounced impact on shaping self-concept.
5. In an experimental study examining whether children who are read to more often score higher on vocabulary tests in first grade, the independent variable would be the __________.
- A. frequency of read-alouds
- B. type of books parents read
- C. child’s vocabulary score Copyright © 2018 Laura E. Berk. All Rights Reserved. 31 Test Bank for Berk, Development Through the Lifespan, 7e
- D. difficulty of vocabulary words Answer: A Page Ref: 33 Skill Level: Apply and limitations of each. Topic: Studying Development Difficulty Level: Difficult
Correct answer: A
Rationale: In an experimental study, the independent variable is the factor being manipulated or controlled by the researcher. In this case, the frequency of read-alouds is the variable that researchers would intentionally change or vary to see its effect on the dependent variable, which is the children's vocabulary scores. The other options (B. type of books parents read, C. child's vocabulary score, and D. difficulty of vocabulary words) are not the independent variable in this study as they are either irrelevant or are the outcome being measured.
