Information Integration Theory

Information integration theory was proposed by Norman H. Anderson to describe and model how a person integrates information from a number of sources in order to make an overall judgment (cognitive science). The theory proposes three functions. The valuation function is an empirically derived mapping of stimuli to an interval scale. It is unique up to an interval exchange transformation. The integration function is an algebraic function combining the subjective values of the information. "Cognitive algebra" refers to the class of functions that are used to model the integration process. They may be adding, averaging, weighted averaging, multiplying, etc. The response production function is the process by which the internal impression is translated into an overt response. https://en.wikipedia.org/wiki/Information_integration_theory
