1. To study the impact of biological aging on motor skills, researchers focus on __________.
- A. sedentary adults
- B. competitive athletes
- C. men in their mid- to late thirties
- D. women in their childbearing years
Correct answer: B
Rationale: The correct answer is B: competitive athletes. Competitive athletes are often studied by researchers to investigate the impact of biological aging on motor skills because their performance is closely linked to physical abilities. Sedentary adults (choice A) may not provide a clear understanding of the relationship between biological aging and motor skills as they may not engage in consistent physical activity. Men in their mid- to late thirties (choice C) and women in their childbearing years (choice D) may not represent a group where motor skills are as finely tuned and critical to performance as in competitive athletes.
2. What are the most obvious organized patterns of behavior in a newborn baby?
- A. Reflexes
- B. States of arousal
- C. Shrill cries
- D. Sleep patterns
Correct answer: A
Rationale: The correct answer is A: Reflexes. Reflexes are automatic, involuntary responses to specific stimuli and are the most obvious organized patterns of behavior in a newborn baby. Examples of newborn reflexes include sucking, rooting, grasping, and the Moro reflex. These reflexes are crucial for the newborn's survival and overall development. Choice B, states of arousal, refers to different levels of consciousness and responsiveness, not organized behavior patterns. Choice C, shrill cries, is a form of communication and not an organized behavior pattern. Choice D, sleep patterns, while important for newborns, are not the most obvious organized behavior patterns.
3. What is the longest stage of labor?
- A. Delivery of the baby
- B. Delivery of the placenta
- C. Dilation and effacement of the cervix
- D. Release of epinephrine and cortisol
Correct answer: C
Rationale: The correct answer is C: Dilation and effacement of the cervix. This stage can last for hours, especially for first-time mothers, as the cervix needs to dilate and efface to allow for the baby's passage through the birth canal. Once the cervix is fully dilated and effaced, the woman can begin pushing during the second stage of labor to deliver the baby. The delivery of the baby itself is usually a shorter process compared to the time taken for the cervix to dilate and efface. Choices A, B, and D are incorrect because they represent other stages within the labor process that come after the dilation and effacement of the cervix.
4. Which of the following best describes a sequential design?
- A. Does not address diversity in developmental outcomes.
- B. Permits researchers to check if cohort effects are operating.
- C. Is less efficient than a longitudinal design.
- D. Makes cross-sectional, but not longitudinal, comparisons.
Correct answer: B
Rationale: A sequential design permits researchers to check if cohort effects are operating. This design involves combining cross-sectional and longitudinal research, allowing for the comparison of different cohorts at different ages. By using this approach, researchers can determine if developmental changes observed are due to age or generation-specific factors. Therefore, a sequential design is valuable in addressing the potential influence of cohort effects on developmental outcomes. Choices A, C, and D are incorrect because a sequential design does not neglect diversity in developmental outcomes, is not necessarily less efficient than a longitudinal design, and can make both cross-sectional and longitudinal comparisons.
5. Anoxia during labor and delivery can cause __________.
- A. spina bifida
- B. anencephaly
- C. cerebral palsy
- D. muscular dystrophy
Correct answer: C
Rationale: Anoxia during labor and delivery can cause cerebral palsy. Cerebral palsy is a group of disorders that affect a person's ability to move and maintain balance and posture. It is caused by damage to the developing brain, often due to a lack of oxygen during labor and delivery. Spina bifida (Choice A) is a neural tube defect that occurs during embryonic development and is not directly caused by anoxia during labor. Anencephaly (Choice B) is a severe neural tube defect where the baby is born without parts of the brain and skull, not typically caused by anoxia during labor. Muscular dystrophy (Choice D) is a genetic disorder characterized by progressive muscle weakness and is not directly related to anoxia during labor and delivery.
