1. 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.
2. According to operant conditioning theory, __________.
- A. the frequency of a behavior can be increased through punishment, such as disapproval
- B. normal development must be understood in relation to each culture's life situation
- C. the id develops as parents insist that children conform to the values of society
- D. the frequency of a behavior can be increased by following it with a wide variety of reinforcers
Correct answer: D
Rationale: According to operant conditioning theory, the frequency of a behavior can be increased by following it with a wide variety of reinforcers. In operant conditioning, behaviors are shaped through reinforcement, which can be positive (rewarding) or negative (removal of something unpleasant). By providing reinforcement following a behavior, the likelihood of that behavior occurring again in the future is increased. This supports the notion that the frequency of a behavior can be increased by using reinforcers in operant conditioning. Choices A, B, and C are incorrect because operant conditioning focuses on the relationship between behavior and its consequences through reinforcement (positive or negative) to increase the likelihood of the behavior recurring, rather than punishment, cultural influences, or the development of the id based on societal values.
3. During the second month of pregnancy, __________.
- A. the umbilical cord first appears as a primitive body stalk
- B. touch sensitivity extends to most of the body
- C. the heart develops separate chambers
- D. the heartbeat can be heard through a stethoscope
Correct answer: C
Rationale: During the second month of pregnancy, the heart of the developing fetus begins to develop separate chambers, forming the structure necessary for a fully functioning heart. This is a significant milestone in the prenatal development process. Choices A, B, and D are incorrect because the appearance of the umbilical cord as a primitive body stalk typically occurs around week 5-6, touch sensitivity extending to most of the body is more characteristic of the end of the second trimester, and the heartbeat is usually detectable through a stethoscope around the 18th to 20th week of pregnancy, not during the second month.
4. Newborn infants who are brain damaged or who have experienced birth trauma often __________.
- A. display disturbed REM-NREM sleep cycles
- B. cry less than those with no brain functioning problems
- C. spend about 20 percent of their total sleep time in REM sleep
- D. have very low or inaudible cries
Correct answer: A
Rationale: Newborn infants who are brain damaged or who have experienced birth trauma often display disturbed REM-NREM sleep cycles. This disruption in the sleep cycle can be a sign of neurological issues and can impact the newborn's overall health and development. Choice B is incorrect because infants with brain damage or birth trauma may actually cry more due to their discomfort or neurological issues. Choice C is incorrect because spending about 20 percent of total sleep time in REM sleep is not necessarily specific to brain-damaged or birth-traumatized infants. Choice D is incorrect because having very low or inaudible cries is not a common characteristic associated with brain damage or birth trauma in infants.
5. According to Piaget, in which stage of cognitive development is four-year-old R’Monte who engages in make-believe play by stirring beads in a bowl and saying, “Soup is ready!�
- A. sensorimotor
- B. preoperational
- C. concrete operational
- D. sociocultural
Correct answer: B
Rationale: According to Piaget's theory of cognitive development, four-year-old R’Monte's engagement in make-believe play, such as pretending to stir beads in a bowl and creating imaginary soup, indicates that he is in the preoperational stage of cognitive development. This stage is characterized by symbolic thinking, pretend play, language development, and egocentrism. Choice A, sensorimotor, is incorrect as this stage occurs in infancy and focuses on sensory experiences and object permanence. Choice C, concrete operational, is incorrect as this stage occurs around ages 7-11 and involves logical reasoning about concrete events. Choice D, sociocultural, is incorrect as it does not correspond to Piaget's stages of cognitive development.
