Abstract

Experimental psychology, though now more than one hundred years old, is still failing in accomplishing its main task: to unify psychology through a consensually valid formulation of the psychological phenomenon and throuhg the proposition of natural science principles able to explain it. This paper is an atempt at: 1) Making explicit the main deficiencies of current experimental approach of behavior in both factual and theoretical grounds; 2) Formulating the essence of the psychological phenomenon with sufficient specificity to differentiate it from the objects of other sciences and with enought generality to encompass under the same definition the different phenomena studied by existent streams of scientific psychology; and, finally, 3) Demonstrating and illustrating, specially in the field of behavior studies, some new principales of natural science for explaining psychological phenomena.
