In cognitive psychology, constructivism is a reaction against the Gibsonian view that knowledge and perception are the result of sensation and maintains that (a) the nervous system, in order to be adaptive, must process available informations actively and construct an internal world and that (b) these processes be describable in a computer language and acceptable for simulation by a computer.

A theory of knowledge and a methodology for its acquisition based on a better understanding of our ways of perception and interpretation of reality.

Constructivism is a reaction against the Gibsonian view that knowledge and perception are the result of sensation.

Constructivist view is not an ontological view (concerned with the existence and ultimate nature of reality) but an epistemological view (concerned with the origin, structure,acquisition, and validity of knowledge).
