Nearly all adults who were children living in Saigon when the U.S. armed forces left Vietnam in 1975 report that their lives were changed by those events. This exemplifies which of the following?

Correct Answer: C

Rationale: The correct answer is C. This scenario exemplifies a critical period in development. Critical periods are specific times in an individual's life when certain events have a profound impact on their development. In this case, the events surrounding the departure of the U.S. armed forces from Saigon in 1975 had a lasting influence on the children living there at that time. Choices A, B, and D are incorrect. Normative age-graded influence refers to events that are common to people of a particular age group, the social clock relates to the culturally preferred timing of social events, and a sensitive period is a time when an individual is more susceptible to environmental influences but does not result in lifelong consequences as with critical periods.

Correct Answer: D

Rationale: Philosopher John Locke characterized the mind of a child as a 'blank slate,' indicating that it is devoid of innate ideas or characteristics. This concept suggests that a child's mind is shaped and developed through experiences and learning rather than having inherent qualities. Choices A, B, and C are incorrect as Locke did not view the mind of a child as innately good, conscientious, or associated with the superego-ideal. Instead, he believed that individuals are born without built-in mental content, emphasizing the importance of environmental influences on cognitive development.

Correct Answer: B

Rationale: Freud believed that castration anxiety among boys leads to the resolution of the Oedipus complex, not penis envy or cognitive learning. The Oedipus complex is a central psychodynamic concept in Freudian theory, where boys develop unconscious desires for their mothers and view their fathers as rivals, fearing castration by their fathers as a consequence.

Correct Answer: D

Rationale: The correct answer is D because one common criticism of Piaget's theory is that children often acquire cognitive abilities earlier than Piaget proposed. This criticism suggests that Piaget's stages might not be as fixed or rigid as he believed. Choices A, B, and C are incorrect: A is a characteristic of Piaget's theory; B is not a common criticism, as research generally supports the existence of Piaget's stages; and C is inaccurate, as Piaget actually emphasized the importance of mental processes in cognitive development.
