Growth and Development Exam
1. Which expectant mother has the greatest risk of a baby born with fetal alcohol syndrome?
- A. Chloe, a Caucasian American
- B. Latima, an African American
- C. Yvonne, a Native American
- D. Ming, an Asian American Answer: C Page Ref: 85 Skill Level: Apply known or suspected teratogens. Topic: Prenatal Environmental Influences Difficulty Level: Moderate
Correct answer: C
Rationale: According to research, Native American populations have the highest prevalence of fetal alcohol syndrome (FAS) in the United States. This increased risk is due to various social, cultural, and environmental factors within Native American communities.
2. By using which method of assignment of participants to treatment conditions, investigators increase the chances that participants' characteristics will be equally distributed across treatment groups?
- A. sequential
- B. random
- C. systematic
- D. correlational
Correct answer: B
Rationale: By using random assignment of participants to treatment conditions, investigators increase the chances that participants' characteristics will be equally distributed across treatment groups. Random assignment helps reduce the likelihood of bias in the selection process and ensures that any differences between groups are due to the treatment and not pre-existing group differences. Sequential, systematic, and correlational assignment methods do not provide the same level of assurance in distributing participants' characteristics equally across treatment groups.
3. To study the impact of biological aging on motor skills, researchers focus on __________.
- A. sedentary adults
- B. competitive athletes
- C. men in their mid- to late thirties
- D. women in their childbearing years
Correct answer: B
Rationale: The correct answer is B: competitive athletes. Competitive athletes are often studied by researchers to investigate the impact of biological aging on motor skills because their performance is closely linked to physical abilities. Sedentary adults (choice A) may not provide a clear understanding of the relationship between biological aging and motor skills as they may not engage in consistent physical activity. Men in their mid- to late thirties (choice C) and women in their childbearing years (choice D) may not represent a group where motor skills are as finely tuned and critical to performance as in competitive athletes.
4. During the period of the embryo, the __________ becomes the __________.
- A. mesoderm; nervous system, lungs, internal organs, and skin
- B. chorion; endocrine system, muscles, placenta, and skeleton
- C. ectoderm; circulatory system, skin, skeleton, and internal organs
- D. endoderm; digestive system, lungs, urinary tract, and glands Answer: D Page Ref: 78 Skill Level: Remember Topic: Prenatal Development Difficulty Level: Moderate
Correct answer: D
Rationale: During the period of the embryo, the endoderm becomes the digestive system, lungs, urinary tract, and glands. The endoderm is one of the primary germ layers that give rise to various internal organs in the developing embryo. It plays a crucial role in the formation of organs such as the digestive system, respiratory system, and glandular structures.
5. The first successful intelligence test was originally constructed to __________.
- A. measure individual differences in IQ
- B. document age-related improvements in children's intellectual functioning
- C. identify children with learning problems who needed to be placed in special classes
- D. compare the scores of people who varied in gender, ethnicity, and birth order
Correct answer: C
Rationale: The first successful intelligence test, the Binet-Simon Scale, was originally developed to identify children with learning problems who required special educational interventions. Choice A is incorrect because measuring individual differences in IQ was not the primary purpose of the test. Choice B is incorrect because documenting age-related improvements in children's intellectual functioning was not the main goal of the test. Choice D is incorrect because comparing the scores of people based on gender, ethnicity, and birth order was not the intended use of the intelligence test.
