Piaget's Theory of Cognitive Development

Here are the review questions with multiple-choice options: 1) What major developmental milestone occurs during the Sensorimotor Stage ($0\text{ to } 2\text{ years}$), characterized by realizing that physical objects continue to exist even when they can no longer be seen or heard? A) Conservation, B) Object permanence, C) Abstract reasoning, D) Deductive logic. 2) What cognitive limitation in the Preoperational Stage ($2\text{ to } 7\text{ years}$) involves difficulty recognizing that properties such as volume or mass stay identical despite changes in shape or arrangement? A) Lack of symbolic play, B) Inability to acquire language, C) Struggle with conservation, D) Absence of motor manipulation. 3) How does problem-solving in the Concrete Operational Stage ($7\text{ to } 11\text{ years}$) differ from that in the Formal Operational Stage ($12\text{ years}$ and older)? A) Concrete operations apply logic to tangible, observable objects, while formal operations allow reasoning about hypothetical, abstract situations. B) Concrete operations involve abstract hypothesis testing, while formal operations rely purely on physical sensory actions. C) Concrete operations lack logical thought entirely, while formal operations focus solely on real-world manipulables. D) Concrete operations focus on pretend play, while formal operations struggle with conservation.
