A Quantum Brain Model of Decision-Making Process Incorporated with Social Psychology

Kazuo Koyama, Keisuke Niwase


In order to understand human mind and brain, the concepts of quantum theory have been applied so far. In this paper, we attempt to construct a quantum brain model of decision-making process, and determine the Hamiltonian, combining with social psychology in Synergetics. We adopt Weidlich model dealing with opinion formation of individuals on psychology. The fundamental idea of our modeling is that the transition process between two opinions in psychology is similar to the one in the quantum two-level system. Thus, we provide not only a new quantum model of brain, but also a new approach of modeling in this field.
