Explanation:

Jean Piaget has given the theory of cognitive development in which he has mentioned four distinct stages including sensorimotor, preoperational, formal operation, and concrete operational.

According to Piaget, the sensorimotor stage consists of six sub-stages that starts from the birth of a child and lasts through twenty-four months.

Secondary Circular Reactions: The sub-stage starts from four months of a child and lasts through eight months of age. At this stage, a child is focused on the world around and starts to repeat a particular action to get a particular response in the surrounding environment. A child becomes more object-oriented in this stage as the child gets aware of things around him or her accept his or her body.
