Human Growth and Development Final Exam Answers
1. According to psychosexual theory, what is crucial for healthy personality development?
- A. Children actively construct knowledge as they manipulate and explore the world.
- B. Directly observable events are the appropriate focus of psychological study.
- C. How parents manage their child's sexual and aggressive drives in the first few years.
- D. The ego makes a positive contribution to development, acquiring attitudes and skills.
Correct answer: C
Rationale: According to psychosexual theory, developed by Sigmund Freud, how parents manage their child's sexual and aggressive drives in the first few years is crucial for healthy personality development. This theory suggests that personality development is heavily influenced by a child's experiences during early stages of development, particularly related to handling sexual and aggressive impulses. Choices A, B, and D are incorrect as they do not align with the core principles of psychosexual theory, which focuses on the importance of early childhood experiences, especially in the context of sexual and aggressive drives.
2. Maryann is pregnant and works in a smoke-filled environment. What can you tell her about passive smoking?
- A. The negative effects of smoking are only evident in children born to heavy smokers.
- B. Passive smoking is related to low birth weight, infant death, and childhood respiratory illnesses.
- C. Smoke-filled environments are harmful to expectant mothers, but not to their unborn children.
- D. The effects of passive smoking are not yet known.
Correct answer: B
Rationale: Passive smoking, also known as secondhand smoke, can have harmful effects on pregnancies. Research has shown that exposure to smoke-filled environments during pregnancy is linked to low birth weight, infant death, and childhood respiratory illnesses. Pregnant women should avoid exposure to secondhand smoke to protect the health of their unborn babies. Choice A is incorrect because passive smoking affects both the mother and the unborn child, not just children born to heavy smokers. Choice C is incorrect as it underestimates the risks of smoke-filled environments on unborn children. Choice D is incorrect as research has already established the harmful effects of passive smoking on pregnancies.
3. In an experiment, the independent variable __________.
- A. is the one the investigator expects to be influenced by another variable
- B. is the one the investigator expects to cause changes in another variable
- C. cannot be manipulated or controlled by the researcher
- D. is the number that describes how two measures are associated with each other
Correct answer: B
Rationale: In an experiment, the independent variable is the one that the investigator expects to cause changes in another variable. It is the factor that is deliberately manipulated or changed by the researcher to observe its effects on the dependent variable. The purpose of manipulating the independent variable is to study its impact on the outcome, allowing researchers to establish cause-and-effect relationships in their investigations. Choice A is incorrect because the independent variable is not influenced but rather influences another variable. Choice C is incorrect as the independent variable is intentionally manipulated by the researcher. Choice D is incorrect as it refers to a different concept unrelated to the independent variable in an experiment.
4. In developing countries, the most readily available intervention for promoting the recovery of preterm babies is _________.
- A. hospitalization
- B. care in an isolette
- C. lying on a waterbed
- D. skin-to-skin 'kangaroo care'
Correct answer: D
Rationale: In developing countries, the most readily available intervention for promoting the recovery of preterm babies is skin-to-skin 'kangaroo care.' This involves direct skin-to-skin contact between the baby and a caregiver, typically the mother, which helps regulate the baby's body temperature, improve bonding, and support overall development. Kangaroo care can be easily implemented even in resource-limited settings and has been shown to have positive effects on preterm infants' health outcomes. Choices A, B, and C are incorrect because hospitalization, care in an isolette, and lying on a waterbed are not specifically tailored interventions that address the unique needs of preterm babies in developing countries like kangaroo care does.
5. When __________, newborn Takeo's toes should fan out and curl as his foot twists in.
- A. a bright light shines in his eyes
- B. his bare foot touches a flat surface
- C. his cheek is stroked near the corner of his mouth
- D. the sole of his foot is stroked from toe to heel
Correct answer: D
Rationale: The correct answer is D because the description of the twisting and fanning out of newborn Takeo's toes suggests the Babinski reflex, which is typically elicited by stroking the sole of the foot from toe to heel. The Babinski reflex is a normal response in newborns and indicates proper neurological development. Choices A, B, and C are incorrect as they do not elicit the specific response described in the question.
