In this paper we checked the principal researches and theories to explain the attention system functioning. We are going to start reviewing along time about the concept of attention, from filter theories and resources distributor theories, to the current theories in which attention is conceived as a control system. From this last point of view, we will emphasize on the attentional networks theory of Posner, that proposes different systems to explain diverse aspects of attention, but they are related to each other. At last in this paper, we will mention experimental results that have been important to characterize the selective attentional mechanisms of the human visual system, using the attentional spotlight model for this aim.
