[EN] Purpose ¿ The purpose of this paper is to investigate the body-mind problem from a mathematical
invariance principle in relation to personality dynamics in the psychological and the biological levels of
description.
Design/methodology/approach ¿ The relationship between the two mentioned levels of description is
provided by two mathematical models as follows: the response model and the bridge model. The response
model (an integro-differential equation) is capable to reproduce the personality dynamics as a consequence of
a determined stimulus. The invariance principle asserts that the response model can reproduce personality
dynamics at the two levels of description. The bridge model (a second-order partial differential equation) can
be deduced as a consequence of this principle: it provides the co-evolution of the general factor of personality
(GFP) (mind), the it is an immediate early gene (c-fos) and D3 dopamine receptor gene (DRD3) gens and the
glutamate neurotransmitter (body).
Findings ¿ An application case is presented by setting up two experimental designs: a previous pilot AB
pseudo-experimental design (AB) pseudo-experimental design with one subject and a subsequent ABC
experimental design (ABC) experimental design with another subject. The stimulus used is the stimulant
drug methylphenidate. The response and bridge models are validated with the outcomes of these
experiments.
Originality/value ¿ The mathematical approach here presented is based on a holistic personality model
developed in the past few years: the unique trait personality theory, which claims for a single personality trait
to understand the overall human personality: the GFP.
