1. 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.

2. Ethnographic research is directed toward understanding a culture through __________ observation.

• A. naturalistic
• B. participant
• C. systematic
• D. structured

Correct answer: B

Rationale: Ethnographic research is directed toward understanding a culture through participant observation. This type of observation involves the researcher immersing themselves in the culture being studied, actively participating in the daily activities and interactions of the group being studied. Through participant observation, researchers can gain a deep and nuanced understanding of the culture from the inside. Choice A, naturalistic observation, typically refers to observing subjects in their natural environment without interference, but it does not involve actively participating in the culture. Choice C, systematic observation, focuses on carefully planned and structured data collection methods but may not involve direct participation. Choice D, structured observation, implies a predefined set of guidelines for observation but lacks the immersive aspect of participant observation.

3. Newborns of smoking mothers __________.

• A. are more attentive to sounds
• B. display more muscle tension
• C. less often have colic
• D. are less excitable when visually stimulated Answer: B Page Ref: 84 Skill Level: Understand known or suspected teratogens. Copyright © 2018 Laura E. Berk. All Rights Reserved. 12 Test Bank for Berk, Development Through the Lifespan, 7e Topic: Prenatal Environmental Influences Difficulty Level: Moderate

Correct answer: B

Rationale: Newborns of smoking mothers display more muscle tension. This is because nicotine in cigarettes can lead to increased muscle tension in babies, which can affect their physical development and potentially lead to future health issues. This is one of the negative effects of smoking during pregnancy on the developing fetus.

4. Low-level radiation, resulting from industrial leakage or medical X-rays, __________.

• A. is harmful only when combined with other teratogens
• B. can increase the risk of childhood cancer
• C. rarely causes lasting damage
• D. is safe during the last trimester

Correct answer: B

Rationale: Low-level radiation, whether from industrial leakage or medical X-rays, can increase the risk of childhood cancer by potentially damaging the developing fetus's cells. Even though the risk is relatively low, it is still a significant concern that should be acknowledged and monitored closely, especially during prenatal development. Choice A is incorrect as low-level radiation can still be harmful on its own without the need to be combined with other teratogens. Choice C is incorrect because low-level radiation exposure can indeed cause lasting damage, especially in the context of childhood cancer risk. Choice D is incorrect because low-level radiation exposure, even during the last trimester, can pose risks to the developing fetus and is not considered entirely safe.

5. What is the most common approach to controlling pain during labor?

• A. an anesthetic
• B. a spinal block
• C. fetal monitoring
• D. epidural analgesia

Correct answer: D

Rationale: Epidural analgesia is the most common approach to controlling pain during labor. It involves the administration of pain medication through a catheter placed in the epidural space of the spine, providing pain relief while allowing the mother to remain alert and participate in the birthing process. It is preferred by many women due to its effectiveness in reducing labor pain. Choices A, B, and C are incorrect as they do not directly address pain management during labor. While an anesthetic and a spinal block are forms of pain relief, epidural analgesia is specifically the most common method used for pain control during labor.
