A growing body of research suggests the appropriateness of social analogues to such psychological constructions as the “law of effect” The focus of this paper is to expand the model to include information about the quality of directive acts and external environmental levels of reinforcement. The expanded multivariable model proposed here provides increased precision and a significant increase in explained variation. The introduction of information concerning environmental considerations shows great promise in expanding applications of the “law of effect” to more natural interaction situations.
