The purpose of this article is to give general vision through the perspectives of several authors, where they will be highlighted in how metacognitive expectations play an important role within a cognitive agent.Cognitive agents are conceived as anticipatory systems; they are able to reason about the future and fulfill their goals thanks to their anticipatory representations. a cognitive agent has to be able to conceive and represent (implicitly or explicitly) its future, including its objectives, and to maintain its predictions and representations accurate. Goals are of primary importance for our analysis since they relate anticipatory mechanisms, representations, and future-oriented conducts. internal models, anticipatory representations and goal-directed behavior have always been related in the analysis of cognitive systems.
