What is the age range of the Sensorimotor stage according to Piaget's developmental stages?

• A. 2 to 7 years
• B. Birth to 2 years
• C. 7 to 11 years
• D. 11 to 15 years

Answer: (B)

The Sensorimotor stage, as defined by Jean Piaget, spans from birth to 2 years of age. During this critical period, infants explore the world primarily through their senses and motor activities. They engage in basic reflexes and gradually develop more complex schemas as they interact with their environment. This stage is pivotal for cognitive development, as infants learn object permanence—the understanding that objects continue to exist even when they cannot be seen—and begin to manipulate objects intentionally.

The age range of this stage is crucial in recognizing the foundational skills that emerge during early childhood, setting the stage for later cognitive development as outlined in Piaget's subsequent stages. The other age ranges provided in the options correspond to Piaget's other stages: the Preoperational stage (2 to 7 years), the Concrete Operational stage (7 to 11 years), and the Formal Operational stage (11 years and up).
