Detailed explanation-1: -The sensorimotor stage is the first of the four stages of Piaget’s theory of cognitive development. It is marked by a child’s knowledge that the outside world exists separately from themselves. Once the child has fully realized this, they will move on to the next stage within Piaget’s stages of development.

Detailed explanation-2: -The main development during the sensorimotor stage is the understanding that objects exist and events occur in the world independently of one’s own actions (’the object concept’, or ‘object permanence’).

Detailed explanation-3: -This is what defines the sensorimotor stage. For example, a baby might giggle or smile because he or she perceived something as funny or interesting. Giggling or smiling is an example of a reaction induced by cognitive development, so it would fall under the sensorimotor stage.

Detailed explanation-4: -The main development during the sensorimotor stage is the understanding that objects exist and events occur in the world independently of one’s own actions (’the object concept’, or ‘object permanence’). Object permanence means knowing that an object still exists, even if it is hidden.
