• B. Eric Erikson
• C. Jean Piaget
• D. Sigmund Freud

Answer: (C)

The four-stage theory of cognitive development, which includes the sensorimotor and preoperational stages, is attributed to Jean Piaget. His theory outlines how children progress through distinct phases of cognitive growth, revealing their evolving ability to think and reason at various ages.

In the sensorimotor stage, which occurs from birth to about 2 years, infants learn about the world primarily through their senses and actions. They begin to develop object permanence and understand the concept of cause and effect. Following this is the preoperational stage, spanning from approximately 2 to 7 years, during which children start to use language and engage in symbolic play but still struggle with understanding abstract concepts and logic.

Piaget's work established a foundational framework for understanding cognitive development in children, emphasizing that children construct knowledge through interactions with their environment in stages that are age-related and sequential. His emphasis on active learning and discovery plays a critical role in educational practices and our understanding of childhood development.
