Growth and Development Exam
1. 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.
2. Prenatally malnourished babies frequently __________.
- A. reject breast milk
- B. have enlarged hearts
- C. catch respiratory illnesses
- D. have a higher-than-average birth weight
Correct answer: C
Rationale: Prenatally malnourished babies frequently catch respiratory illnesses. Malnourished babies have weakened immune systems, making them more susceptible to illnesses such as respiratory infections. This is a common consequence that is observed in babies who did not receive adequate nutrition during the prenatal period. Choices A, B, and D are incorrect. While malnourished babies may have feeding challenges, rejecting breast milk is not a common consequence. Enlarged hearts are not typically associated with prenatal malnutrition, and having a higher-than-average birth weight is unlikely in malnourished babies.
3. 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.
4. What is the goal of applied behavior analysis?
- A. outline changes in temperament over the lifespan
- B. eliminate undesirable behaviors and increase desirable responses
- C. examine how we think about ourselves and other people
- D. synthesize information from various sources into a detailed picture of a person's personality
Correct answer: B
Rationale: The correct answer is B: "eliminate undesirable behaviors and increase desirable responses." Applied behavior analysis aims to modify behavior by focusing on eliminating unwanted behaviors and reinforcing desirable ones. It does not primarily deal with changes in temperament (choice A), self-perception (choice C), or personality traits (choice D). The approach involves techniques such as reinforcement to target specific behaviors, rather than broader cognitive processes or personality characteristics.
5. In the __________ period, teratogens rarely have any impact.
- A. germinal
- B. embryonic
- C. fetal
- D. prenatal
Correct answer: A
Rationale: In the germinal period of prenatal development, which lasts for about the first two weeks after fertilization, the developing organism is a zygote that has not yet implanted in the uterus. During this period, teratogens rarely have any impact because essential implantation and early cellular division processes are occurring. Teratogens are more likely to have significant effects during the later embryonic and fetal periods of development. Therefore, the correct answer is A. Choice B, embryonic period, is incorrect because teratogens have a higher likelihood of impacting development during this period. Choice C, fetal period, is also incorrect as teratogens can impact development during this stage as well. Choice D, prenatal, is a broad term encompassing the entire period of development from conception to birth and is not a specific developmental stage where teratogens have a minimal impact.
