The problems with the variety of definitions of Psychology are analyzed, and the advantages from the point of view of Behavior Analysis, on defining Psychology as the study of organism-environment relations.

The experimental analysis of behavior uses contingencies and functional relationships as tools for the study of organism-environment relations.
