Before revision:  In doing so, the same model as for the Ideal Gases (IG) emerges from the experimental reaction time data. We show that the law governing the experimental RT of a group of individuals is the same as the law governing the dynamics of an inanimate system , namely, a system of non-interacting particles (IG) . Both systems are characterized by a collective parameter which is k_BT for the system of particles and what we have called life span parameter for the system of brains.
