Answer:

Step-by-step explanation:
Sensorimotor stage: In psychology, the term sensorimotor stage is the very first stage in the theory of cognitive development which was proposed by Jean Piaget. This stage begins from the birth of the child and lasts through two years of age. At this stage, an infant starts to learn about the world around him or her by using his or her senses to interact with the environmental surroundings.
In the sub-stage of the sensorimotor stage named primary circular reaction, a child tends to suck things and tends to repeat the procedure to get pleasure.
