Baby Lucy is 8 months old. She picks up a toy in her crib and accidentally hits her crib with the toy, making an interesting noise. She begins to drag the toy back and forth against the sides of the crib's railing, which produces another different and interesting sound. This prompts Lucy to continue repeating the action over and over again. Piaget would say that this is an example of

Secondary circular reactions.

Explanation:

Jean Piaget's hypothesis indicates that children are going through four distinct levels of cognitive development and the sensory-motor stage is the earliest among them. This stage is further subdivided into six sub-stages. Primary Circular Reactions is them second sub-stage and it includes the integration of feeling and new schemas. For eg, 8 months old Lucy drags the toy back and forth against the sides of the crib's railing to produce different sounds and then deliberately repeats the action later. Such acts are repeated as the child finds them satisfying.
