The equation was proposed as an attempt to unify the different branches of psychology (e.g. child psychology, animal psychology, psychopathology) with a flexible theory applicable to all distinct branches of psychology. [3] This equation is directly related to Lewin's field theory.
Paul Meehl was born January 3, 1920, in Minneapolis, Minnesota, to Otto and Blanche Swedal.His family name "Meehl" was his stepfather's. [3] When he was age 16, his mother died as the result of poor medical care which, according to Meehl, greatly affected his faith in the expertise of medical practitioners and diagnostic accuracy of clinicians.

Probability theory or probability calculus is the branch of mathematics concerned with probability.Although there are several different probability interpretations, probability theory treats the concept in a rigorous mathematical manner by expressing it through a set of axioms.
In physics, there are equations in every field to relate physical quantities to each other and perform calculations. Entire handbooks of equations can only summarize most of the full subject, else are highly specialized within a certain field. Physics is derived of formulae only.
The concept first made its appearance in psychology with roots in the holistic perspective of Gestalt theories. It was developed by Kurt Lewin, a Gestalt psychologist, in the 1940s. Lewin's field theory can be expressed by a formula: B = f(p,e), meaning that behavior (B) is a function of the person (p) and their cultural environment (e). [1]
Psychophysics quantitatively investigates the relationship between physical stimuli and the sensations and perceptions they produce. Psychophysics has been described as "the scientific study of the relation between stimulus and sensation" [1] or, more completely, as "the analysis of perceptual processes by studying the effect on a subject's experience or behaviour of systematically varying the ...
The multiple realizability thesis in the philosophy of mind posits that the same mental state can be realized by different physical states; another way of putting it is that there is a many-to-one mapping from physical states to mental states. [2] Multiple realizability in general is not restricted to the multiple realizability of mental states.
E p is the relativistic energy for a momentum p quantum of the field, = + when the rest mass is m. a r ( p ) and b r † ( p ) {\displaystyle b_{r}^{\dagger }(\mathbf {p} )} are annihilation and creation operators respectively for "a-particles" and "b-particles" respectively of momentum p ; "b-particles" are the antiparticles of "a-particles".
