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. An experimental design __________.
- A. allows researchers to gather information in natural life circumstances without altering the participants' experiences
- B. looks at relationships between participants' characteristics and their behavior or development
- C. permits inferences about cause and effect because researchers evenhandedly assign people to treatment conditions
- D. has one major limitation: researchers cannot infer cause and effect
Correct answer: C
Rationale: An experimental design permits inferences about cause and effect because researchers evenhandedly assign people to treatment conditions. This means that researchers can manipulate certain variables and observe the effects on participants, allowing them to determine causation between variables. This is a key strength of experimental research designs. Choices A, B, and D are incorrect because they do not accurately describe the primary purpose or strength of experimental designs. Experimental designs do not focus on gathering information in natural life circumstances (A), looking at relationships between characteristics and behavior (B), or have the limitation of not being able to infer cause and effect (D).
3. Researchers randomly assigned adolescents to either a single-grade classroom or a mixed-age classroom. This is an example of a __________.
- A. naturalistic observation
- B. case study
- C. natural experiment
- D. field experiment
Correct answer: D
Rationale: In this scenario, the researchers randomly assigned adolescents to either a single-grade classroom or a mixed-age classroom, which is an example of a field experiment. A field experiment involves manipulating independent variables in a natural setting to observe the effects on participants. This design allows for more control over variables compared to naturalistic observation, case studies, or natural experiments. Naturalistic observation involves observing subjects in their natural environment without manipulating any variables. A case study focuses on in-depth analysis of a single individual or a small group. A natural experiment involves observing naturally occurring events without intervention or manipulation by the researcher.
4. Around __________, Baby Alanna should begin to prefer a salty taste to plain water.
- A. 2 weeks
- B. 6 weeks
- C. 2 months
- D. 4 months
Correct answer: D
Rationale: At around 4 months of age, babies begin to develop a preference for salty taste over plain water. This preference is part of their sensory development and exploration of tastes. Introducing a variety of flavors, including salty tastes, at this stage helps broaden the baby's palate and acceptance of different foods later on. Choices A, B, and C are incorrect as babies typically do not develop a preference for salty tastes over plain water at 2 weeks, 6 weeks, or 2 months of age. These earlier stages are more focused on milk feeding and the introduction of solid foods usually begins around 4-6 months of age.
5. How can families prevent escalating demands that lead to chaos?
- A. Parental multitasking
- B. Eating separate meals
- C. Compression of family routines
- D. High-quality child care that is affordable and reliable
Correct answer: D
Rationale: High-quality child care that is affordable and reliable can help prevent escalating demands on families that lead to chaos. This is achieved by providing a stable and supportive environment for children, enabling parents to balance work and family responsibilities effectively. Access to reliable child care reduces stress and helps in preventing chaos within the family, ultimately leading to improved well-being for both parents and children. Choices A, B, and C are incorrect as they do not directly address the need for external support to manage family demands and prevent chaos. Parental multitasking, eating separate meals, and compressing family routines may not provide the necessary stability and support required to prevent escalating demands on families.
