Cognitive development in the stage involves changing from reflex behavior to intentional action and the attainment of object permanence.

Sensorimotor stage

Explanation:

The sensorimotor stage of development, is the first stage of cognitive development of infants, children, and adolescents.  A child of about 2 years of age, is in the sensorimotor stage.

Infants at the early stage of life, sense what is directly in front of them. Their learning pattern at this early stage is a trial and error pattern involving gripping, throwing etc.

As soon as the object is taken away from the direct view of an infant, it ceases to exist to him/her. This is because objects exist to infants when they can sense them and interact with them.

.A significant development during the sensorimotor stage is the understanding of an infant that objects exist and that events occur in the world independently from their actions and what they sense.The infant now has a representation of the object and realizes the object can still exist independently.This is known as object permanence
