Explanation:

A famous psychologist named Jean Piaget has given the theory of cognitive development in which he has mentioned four distinct stages including sensorimotor, preoperational, concrete operational, and formal-operational stage.

Sensorimotor stage: This is the first stage in Piaget's cognitive developmental theory, and starts from the birth of the child and lasts through two years of age. In this stage, a child interacts with his or her surrounding by using his or her senses.

The stage is being named as sensorimotor by Piaget because the early manifestations of a child's intelligence start from motor activities and sensory perceptions.

In the question above, Tim's behavior suggests that he is in the sensorimotor stage of cognitive development.
