Which stage of Piaget's cognitive development occurs from birth to 2 years of age?

The sensorimotor stage is the first of Piaget's stages of cognitive development and spans from birth to about 2 years of age. During this time, infants learn through interacting with their environment using their senses and motor actions. They explore the world, develop object permanence, and begin to understand that their actions can produce certain effects.

In this stage, children engage in activities such as grasping, reaching, and manipulating objects. They learn that objects continue to exist even when they cannot be seen, which is a crucial developmental milestone. This foundational learning sets the stage for more complex thinking and reasoning skills that will emerge in later stages of development. By understanding the world through physical experiences, infants begin to form the essential cognitive structures that will support their future learning.
