This paper presents a first approximation of a dynamic emotional
model to be employed in agent societies. The proposed model is
based on the PAD emotional model and allows the representation of
the emotional contagion phenomena of a heterogeneous group of agents
which are capable of express emotions. Moreover, the proposal allows
the definition of the social emotion of this group of agents. The model is
mainly based on three elements: personality, empathy and affinity. These
elements allow the characterization of each individual, causing them susceptible
to vary in some degre the emotions of other individuals
