Initially the human being has that to communicate with the way, to interact with and on such. This used term and> for the fact of the human being to depend primarily on the socialization with the way for its survival, consequently to develop themselves. We can conclude then that the contingencies acquired in contact with the medias will be responsible, in part, in the infantile development. Vygostsky was convinced of that complex forms of thought have its origin in social interactions and not in the individual exploration of each child. The contact with the media televises not and an individual exploration and yes a factor of the social interactions, therefore the child receives the information and later she socializes it with its half the people compose who it. According to Chomsky (1999) apud Macedo, (1999, P. 5) the true knowledge comes through the discovery of the truth and not through the imposition of an official truth great interests of the corporation: More than let us see close what it means to teach to the truth and the people to distinguish lies from truths. I find that not and necessary more than what common-sense, exactly common-sense that allows in them to adopt a position criticizes before the propaganda systems However, the children are still in development they do not possess the capacity to distinguish which would be the true knowledge and what it tax, we have then that to verify where phase of the development the children already possess the notion of what he would be true. Piaget (1919) in its theory of development defends that this infantile development possesss four phases, first that and the period of training sensrio-engine where the child does not have mental representation in objects, as that and the daily pay-operational period of training where the child already associates the object and the meaning, the third that and period of training of the concrete operations where already operations of thought instead of simple action exist and finally the period of training of the formal operations that occurs the reasoning of abstract thoughts.
