This paper presents a generic model for a cognitive agent based on the hypothesis that the cognitive activity has three main characteristics: self-organization, evolutionary nature and hisotry dependence. According to this model, a cogntiive agent presents three levels; reactive, instinctive and cognitive. Each level, together with its lower levels, is itnended to model a compelte agent, each new level just increasing the behavior complexity. The generic model is instantiated into a computational architecture that integrates connectionist, evolutionary computation and symbolic approaches.
