What is largely responsible for the worldwide rise in cesarean deliveries?

Correct Answer: C

Rationale: Medical control over childbirth is largely responsible for the worldwide rise in cesarean deliveries. Cesarean deliveries are often performed due to various medical interventions such as monitoring the progress of labor, fetal distress, and other complications that may arise during childbirth. The increasing use of medical interventions and technology has contributed to the higher rate of cesarean deliveries globally. Choices A, B, and D are incorrect because they do not directly involve the decision-making and interventions typically carried out by medical professionals during childbirth, which are major factors leading to the rise in cesarean deliveries.

Correct Answer: A

Rationale: Natural childbirth experts Grantly Dick-Read and Fernand Lamaze recognized that cultural attitudes about childbirth had taught women to fear the birth experience. They believed that this fear contributed to increased pain during labor and advocated for methods to reduce fear and promote relaxation during childbirth. Choice B is incorrect as the focus is on fear, not on techniques to lessen pain. Choice C is incorrect as the experts did not advocate against medical intervention but rather against unnecessary fear. Choice D is incorrect as the experts aimed to change attitudes towards childbirth, not redirect focus to child rearing.

Correct Answer: A

Rationale: Sigmund Freud constructed his psychosexual theory on the basis of his adult patients' memories of painful childhood events. Freud believed that events in early childhood had a significant impact on an individual's development and personality. He used his patients' recollections of childhood experiences to develop his theories on psychosexual development. Choice B is incorrect as Freud did not base his theory on studies of animal behavior. Choice C is incorrect as Freud's theory was not solely based on interviews with institutionalized children and adolescents. Choice D is incorrect as Freud did not construct his theory by observing his own children.

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.

Correct Answer: A

Rationale: The most consistent asset of resilient children is a strong bond with a competent, caring adult. This relationship provides crucial support, guidance, and positive role modeling, fostering resilience in children. While intelligence (choice B) can be beneficial, it is not as consistently impactful as a supportive adult bond. An easygoing temperament (choice C) may help, but it is not as universally present in resilient children. Associating with rule-abiding peers (choice D) can be helpful, but the connection with a caring adult is more significant in promoting resilience.

Correct Answer: C

Rationale: Self-reports can range from relatively unstructured interviews to highly structured interviews, questionnaires, and tests. This variety allows researchers to collect information from participants in different ways, depending on the research goals and the type of information being sought. Choices A, B, and D are incorrect because they do not accurately describe the range and flexibility of self-reports as outlined in the field of research methodology.

Correct Answer: B

Rationale: The criticism that the information-processing approach ignores transformation in adulthood, concluding that no major cognitive changes occur after adolescence, suggests a limitation of the theory in not fully acknowledging that cognitive development continues throughout the lifespan. This criticism highlights a potential drawback of the approach in terms of its understanding of cognitive changes beyond adolescence. Choice A is incorrect because the criticism is not about underestimating the individual's contribution. Choice C is also incorrect as the criticism is not related to age-specific competencies. Choice D is incorrect as it focuses on a different aspect of the information-processing approach.

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.

Correct Answer: D

Rationale: Quiet alertness is indeed the most fleeting state of arousal. This state is characterized by a newborn infant being awake, calm, and attentive, but it is short-lived and transitions quickly to other states of arousal. Regular sleep, REM sleep, and drowsiness are not considered as brief and transitional as quiet alertness in newborn infants.
