Human Growth and Development Final Exam Answers
1. A combined Apgar score of __________ indicates that the infant is in good physical condition.
- A. less than 3
- B. 3 or 4
- C. 5 or 6
- D. 7 or better
Correct answer: D
Rationale: A combined Apgar score of 7 or better indicates that the infant is in good physical condition. The Apgar score is a quick assessment of a newborn's overall health shortly after birth. It evaluates the baby's heart rate, respiratory effort, muscle tone, reflexes, and color. A score of 7 or higher indicates that the baby is adjusting well to life outside the womb. Choices A, B, and C are incorrect as they represent scores that indicate the infant may need medical attention or assistance as they are below the threshold of 7 which signifies good physical condition.
2. To overcome some of the limitations of traditional developmental designs, investigators sometimes use __________ designs, in which they conduct several similar cross-sectional or longitudinal studies.
- A. sequential
- B. experimental
- C. correlational
- D. quasi-experimental Answer: A Page Ref: 36 Skill Level: Remember Topic: Studying Development Difficulty Level: Easy
Correct answer: A
Rationale: Sequential designs involve conducting multiple similar cross-sectional or longitudinal studies to overcome limitations of traditional developmental designs. By combining different types of study designs, researchers can gain a more comprehensive understanding of development over time. This approach allows for more robust conclusions and can help address potential confounding variables that may impact the results.
3. 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.
4. __________ love is strong at the beginning of a relationship.
- A. Compassionate
- B. Affectionate
- C. Passionate
- D. Companionate
Correct answer: C
Rationale: Passionate love is characterized by intense emotions and physical attraction, which are common in the early stages of relationships. Compassionate love involves deep affection, but it develops over time based on mutual respect, trust, and intimacy. Affectionate love is warm and tender, but it may not necessarily have the intense emotions associated with passionate love. Companionate love is based on friendship, respect, and affection, but it may lack the intense emotions and physical attraction that characterize passionate love.
5. 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.
