Generation of Relations between Individuals based on a Stochastic Automaton and an Analogy from Social Psychology

We regard internal states of an automaton as emotional states of an individual, its outputs as its actions towards another individual, and a parameter a ecting its state transition as a personal trait. We therefore propose a representation of an individual with emotional states and a certain personality, by a stochastic automaton and a model of a group in which each individual begins conversations with another individual. The relations between individuals are generated from results of the conversations based on the congruity theory in social psychology.
