1. When trying to soothe a crying baby, what technique do Western parents typically attempt first?
- A. Massaging the baby's body
- B. Offering a pacifier and a receiving blanket
- C. Playing recorded womb sounds or sounds of nature
- D. Lifting the baby to the shoulder and rocking or walking
Correct answer: D
Rationale: When Western parents aim to soothe a crying baby, the technique they usually try first is lifting the baby to the shoulder and rocking or walking. This method is effective because the motion and closeness provided by rocking or walking can help calm the baby and offer comfort. Choice A is incorrect as massaging the baby's body is not typically the first technique used. Choice B is incorrect as offering a pacifier and a receiving blanket may be tried after lifting the baby to the shoulder. Choice C is also incorrect as playing recorded sounds is usually not the initial technique attempted.
2. The more alcohol a woman consumes during pregnancy, the __________.
- A. higher the birth weight of the child
- B. greater the likelihood of ARND instead of FAS or p-FAS
- C. poorer the child's achievement scores in the school years
- D. greater the child's speed of information processing
Correct answer: C
Rationale: The correct answer is C: 'poorer the child's achievement scores in the school years.' Prenatal exposure to alcohol has been linked to a range of cognitive and behavioral difficulties, including lower academic achievement in children. These difficulties may manifest as poor achievement scores in later school years. Choices A, B, and D are incorrect because alcohol consumption during pregnancy is not associated with higher birth weight of the child, the likelihood of ARND instead of FAS or p-FAS, or greater speed of information processing in the child.
3. Among all Western nations, which country has the highest percentage of extremely poor children?
- A. the United States
- B. Canada
- C. Germany
- D. France
Correct answer: A
Rationale: The correct answer is 'the United States.' According to the information provided, the United States has the highest percentage of extremely poor children among Western nations. This is supported by the extract, which states that the United States leads in this aspect. Choices B, C, and D are incorrect as the question specifically asks for the country with the highest percentage of extremely poor children among Western nations, which is the United States.
4. In mammals, including humans, the sense of smell __________.
- A. does not become adultlike for several years
- B. helps mothers and babies identify each other
- C. is the least developed sense at birth
- D. takes about four months to become adultlike
Correct answer: B
Rationale: The sense of smell in mammals, including humans, plays a crucial role in helping mothers and babies identify each other. This is important for initiating bonding and caregiving behaviors. Choice A is incorrect because the sense of smell is functional at birth and not entirely underdeveloped for several years. Choice C is incorrect as the sense of smell is actually well-developed at birth. Choice D is incorrect because the sense of smell is functional from birth and does not take several months to become adultlike.
5. Today, research that combines an experimental strategy with __________ approach is becoming increasingly common.
- A. both a correlational and a sequential
- B. either a correlational or a sequential
- C. either a longitudinal or a cross-sectional
- D. both a correlational and a longitudinal
Correct answer: C
Rationale: The blank in the statement refers to an approach that can be used in combination with an experimental strategy. Longitudinal and cross-sectional approaches are two common research methods in developmental psychology. Longitudinal studies involve following the same group of individuals over an extended period, while cross-sectional studies compare different groups of individuals of different ages at the same time. By combining an experimental strategy with either a longitudinal or a cross-sectional approach, researchers can gain a deeper understanding of developmental processes and changes over time. Choices A, B, and D are incorrect because correlational and sequential are not the most relevant approaches when studying developmental changes over time in research.
