In the scenario where parents at Central Elementary School responded to a multiple-choice questionnaire regarding the most important activity they do with their child, this is an example of a __________.

Correct Answer: A

Rationale: A structured interview involves asking individuals a predetermined set of questions in a set order. In this scenario, parents at Central Elementary School were given a multiple-choice questionnaire, which indicates that the questions were predetermined and likely asked in a specific order. This method allows for standardized data collection and comparison across participants. Choice B, clinical interview, involves in-depth questioning aimed at understanding an individual's thoughts, feelings, and behaviors related to psychological issues, which is not the case here. Choice C, naturalistic observation, involves observing individuals in their natural environment without interference, which is not applicable to a questionnaire scenario. Choice D, structured observation, involves systematically observing behavior in predefined ways, not relevant to the given scenario of questionnaire responses.

Correct Answer: A

Rationale: The correct answer is A: Nonnormative. Nonnormative influences are events or experiences that are irregular and unique to the individual, so they do not follow a predictable timetable. These influences can include major life events like winning the lottery or experiencing a natural disaster, and they have a significant impact on a person's development. Choice B, History-graded influences, are events that are common to people of a particular generation due to historical circumstances. Choice C, Age-graded influences, are events that are typical for people of a certain age group. Choice D, Bio-historical, is not a recognized term in developmental psychology.

Correct Answer: B

Rationale: The correct answer is B: 'In South Africa, 30 percent of all pregnant women are HIV-positive.' This statement is true as South Africa has a high prevalence of HIV among pregnant women, emphasizing the need for interventions to prevent mother-to-child transmission. Choices A, C, and D are incorrect. Choice A is inaccurate as women account for more than 50% of new HIV infections globally. Choice C is misleading as the majority of new HIV infections actually occur in sub-Saharan Africa, not just developing countries. Choice D is also incorrect as without treatment, the risk of mother-to-child transmission is higher than 30%.

Correct Answer: A

Rationale: Lev Vygotsky viewed cognitive development as a socially mediated process, emphasizing the role of social interactions and cultural influences in shaping a child's cognitive development. This is in contrast to Jean Piaget, who focused more on individual interactions with the environment. Vygotsky believed that cognitive development is significantly influenced by social interactions with others, highlighting the importance of collaborative learning and cultural context. Choices B, C, and D are incorrect as they do not align with Vygotsky's perspective on cognitive development.

Correct Answer: B

Rationale: Lily weighed 8 pounds and was 21 inches long at birth. Being both heavier and longer than average babies typically are at birth, Lily would be considered heavier and longer compared to the average baby. This makes choice B, 'heavier and longer,' the correct answer. Choices A, C, and D are incorrect because Lily was not shorter or lighter than the average baby at birth.

Correct Answer: B

Rationale: Low-level radiation, whether from industrial leakage or medical X-rays, can increase the risk of childhood cancer by potentially damaging the developing fetus's cells. Even though the risk is relatively low, it is still a significant concern that should be acknowledged and monitored closely, especially during prenatal development. Choice A is incorrect as low-level radiation can still be harmful on its own without the need to be combined with other teratogens. Choice C is incorrect because low-level radiation exposure can indeed cause lasting damage, especially in the context of childhood cancer risk. Choice D is incorrect because low-level radiation exposure, even during the last trimester, can pose risks to the developing fetus and is not considered entirely safe.

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.

Correct Answer: A

Rationale: The correct answer is A: ethnography. Ethnography is a research method borrowed from the field of anthropology. It involves observing and documenting behaviors and interactions in a naturalistic setting. This method allows researchers to gain insight into the cultural context and practices of a group through direct observation and participation. Choices B, C, and D are incorrect because clinical interviews, structured interviews, and systematic observations are research methods used in different contexts and fields, not borrowed specifically from anthropology.

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.
