Most hybrid agent architectures are constructed with a hierarchical succession of reactive (at a lower level) and cognitive (at a higher level) layers. Each of these layers represents a behavior, a function, a decision, etc. Instead of using such functional layers, we propose in this paper a generic model of a social hybrid agent, which is based on natural (human/animal) motivations of the agent. We discuss here the contribution of our approach in hybrid agent modeling. The present work uses the American psychologist Abraham Maslow’s pyramid of needs. The basis of this modeling uses the result of an existing psychological study
