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. In an investigation of over 120,000 New York City births, babies born even 1 to 2 weeks early __________ than children who experienced a full-length prenatal period.
- A. showed lower reading and math scores at a third-grade follow-up
- B. were less likely to suffer from childhood obesity
- C. were less likely to suffer from neurological impairments
- D. showed higher language and social/emotional scores in early childhood
Correct answer: A
Rationale: In the investigation of over 120,000 New York City births, babies born even 1 to 2 weeks early showed lower reading and math scores at a third-grade follow-up compared to children who experienced a full-length prenatal period. This suggests that being born slightly premature can have an impact on cognitive development, leading to educational challenges later on. Choices B, C, and D are incorrect because the study specifically highlighted lower reading and math scores, not a reduced likelihood of suffering from childhood obesity or neurological impairments, or improved language and social/emotional scores in early childhood.
3. 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.
4. The negative outcome of Erikson's midlife stage, stagnation, focuses on __________.
- A. role confusion
- B. selflessness
- C. self-indulgence
- D. guilt and shame
Correct answer: C
Rationale: The correct answer is C: 'self-indulgence'. Stagnation in Erikson's midlife stage refers to a lack of growth and self-indulgence, leading to a feeling of unproductiveness. This contrasts with 'role confusion' (A), which is associated with Erikson's adolescence stage, 'selflessness' (B) which is a positive trait, and 'guilt and shame' (D) which are emotions typically associated with earlier stages of development.
5. According to research on family chaos, mothers who __________ experience greater psychological stress.
- A. make family meals
- B. frequently multitask
- C. work outside the home
- D. cosleep with their infants
Correct answer: B
Rationale: According to research on family chaos, mothers who frequently multitask experience greater psychological stress. Multitasking can lead to increased stress levels as individuals juggle multiple responsibilities and tasks simultaneously, leading to a sense of being overwhelmed and unable to focus effectively. This can contribute to higher levels of psychological stress for mothers in particular, impacting their overall well-being. Choices A, C, and D are incorrect because the research specifically links frequent multitasking, not making family meals, working outside the home, or cosleeping with infants, to greater psychological stress among mothers.
