Leah plays patty-cake with her 6-month old child. The child delights in clapping her hands against her mother's hands. What sensorimotor stage is the child exhibiting?

Stage three

Explanation:

In the theory of cognitive development, the sensorimotor stage is the very first stage and is developed by Jean Piaget. This stage generally starts from the birth of the child and lasts through two years of age. In the sensorimotor stage, a child uses his or her senses to interact with the environmental surrounding. The sensorimotor stage consists of six different sub-stages.

Sub-stage three is the secondary circular reactions. At this sub-stage, the child learns to interact with different objects present in the environment and starts from four months of age and lasts through eight months. The child tends to repeat a particular behavior to get specific responses.
