"genetic epistemology".

that happen during cognitive development, it is important first to examine a few of the important ideas and concepts introduced by Piaget.
The following are some of the factors that influence how children learn and grow:

understanding and knowing. Schemas are categories of knowledge that help us to interpret and understand the world.
In Piaget's view, a schema includes both a category of knowledge and the process of obtaining that knowledge. As experiences happen, this new information is used to modify, add to, or change previously existing schemas.
For example, a child may have a schema about a type of animal, such as a dog. If the child's sole experience has been with small dogs, a child might believe that all dogs are small, furry, and have four legs. Suppose then that the child encounters an enormous dog. The child will take in this new information, modifying the previously existing schema to include these new observations.
