Which developmental stage, according to Piaget, involves children exploring the world through their mouth and hands?

• A. Preoperational Stage
• B. Concrete Operational Stage
• C. Sensorimotor Stage
• D. Formal Operational Stage

Answer: (C)

The correct answer, the Sensorimotor Stage, is a key phase in Jean Piaget's theory of cognitive development that occurs from birth to approximately two years of age. During this stage, children actively learn about their environment primarily through their senses and motor actions. They use their mouth and hands to explore objects, which is crucial for cognitive development as it allows them to interact with the world around them.

Through these sensory and motor experiences, infants develop an understanding of object permanence and the idea that objects continue to exist even when they are not visible. The focus on exploration through physical interaction reinforces the notion that children learn by doing and experiencing, forming the foundation for further cognitive development in later stages. This exploration through sensory input is unique to the Sensorimotor Stage and is essential for building knowledge and understanding of their environment.
