1. In field experiments, researchers __________.

• A. selectively assign participants to treatment conditions in natural settings
• B. cannot use random assignment or manipulate treatment conditions
• C. randomly assign participants to treatment conditions in natural settings
• D. have stronger control over the treatment than in the laboratory

Correct answer: C

Rationale: In field experiments, researchers randomly assign participants to treatment conditions in natural settings. This method allows for a higher level of control over potential confounding variables compared to non-random assignment. Random assignment helps ensure that the groups being compared are comparable at the beginning of the study, which strengthens the internal validity of the research findings. Choice A is incorrect because selective assignment may introduce bias. Choice B is incorrect as researchers can use random assignment in field experiments. Choice D is incorrect because field experiments typically have less control over the treatment compared to laboratory experiments.

2. The term teratogen refers to __________.

• A. any environmental agent that causes damage during the prenatal period
• B. a limited time span during which a part of the body is biologically prepared to develop rapidly
• C. a rapid period of prenatal neurological development
• D. a synthetic hormone used to prevent miscarriage

Correct answer: A

Rationale: The correct answer is A: 'any environmental agent that causes damage during the prenatal period.' A teratogen is any substance or factor that can cause harm to the developing fetus during pregnancy. Choice B is incorrect because it describes a critical period, not a teratogen. Choice C is incorrect as it refers to a specific period of development, not a teratogen. Choice D is incorrect because it describes a synthetic hormone, not a teratogen.

3. Which statement describes a strength of naturalistic observation?

• A. It reflects the participants' everyday lives.
• B. It permits comparisons of participants' responses.
• C. Great depth and breadth of information can be obtained in a short time.
• D. It grants each participant an equal opportunity to display the behavior of interest.

Correct answer: A

Rationale: Naturalistic observation reflects the participants' everyday lives because it involves observing individuals in their natural environments without any manipulation. This allows researchers to see how people behave in real-world settings and can provide valuable insights into their typical behavior patterns. Choice B is incorrect because naturalistic observation focuses on observing behavior in its natural setting rather than comparing responses between participants. Choice C is incorrect as naturalistic observation tends to provide rich, qualitative data rather than a large amount of information in a short time. Choice D is incorrect because in naturalistic observation, participants are observed as they naturally behave, which may not always lead to an equal opportunity for all participants to display the behavior of interest.

4. Which statement about interventions that support parents and preterm infants is true?

• A. Preterm infants whose parents receive coaching show no gains in mental test performance.
• B. Babies who are both preterm and economically disadvantaged require long-term, intensive intervention.
• C. For economically disadvantaged parents of preterm infants, just a few sessions of coaching are required.
• D. Even for parents with adequate economic and personal resources, long-term, intensive intervention is necessary. Answer: B Page Ref: 100 Skill Level: Understand Copyright © 2018 Laura E. Berk.

Correct answer: B

Rationale: Babies who are both preterm and economically disadvantaged typically require long-term, intensive intervention. This is because the combination of being born preterm and being economically disadvantaged can pose significant challenges for the infant's development. Providing ongoing support and interventions can help address these challenges and promote healthy development in these infants.

5. In his research study, Dr. Johnson gives participants false feedback about their performance. Consequently, Dr. Johnson should use __________ after the research session is over. Copyright © 2018 Laura E. Berk. All Rights Reserved. 37 Test Bank for Berk, Development Through the Lifespan, 7e

• A. informed consent
• B. a privacy statement
• C. debriefing
• D. a placebo Answer: C Page Ref: 39 Skill Level: Apply Topic: Ethics in Lifespan Research Difficulty Level: Moderate

Correct answer: C

Rationale: Dr. Johnson should use debriefing after the research session is over because giving participants false feedback may have affected them psychologically. Debriefing involves explaining the true nature of the study, including any deception that occurred, to the participants in order to protect their well-being and address any lingering concerns or misconceptions they may have. It is an important ethical practice in research to ensure participants are fully informed about the study they were involved in.
