Unified Psychology Based on Three Laws of Information Integration

How are multiple variables integrated into a unitary response? This fundamental problem- integration of multiple variables-faces every field of psychology. Solid support for three exact mathematical integration laws-averaging, adding, multiplying-has been given by extensive empirical work by investigators in many countries. These three integration laws operate in almost every area of human psychology: person science, social attitudes, child development, learning/memory, language, psychophysics, and judgment-decision. These laws have nomothetic generality across persons and cultures together with idiographic capability for true measurement of personal, individual value. These integration laws are thus a foundation, both conceptual and empirical, for unifying psychological science.
