The communicative function this narrowly on with the thought that is a basic function that allows the social interaction and still it has function to organize the thought. The language as Vygotsky pass for three phases: the first one appears as function to call and to communicate, and later the self-centered language and on interior language to the thought. The language as function to call and to communicate has paper importantssimo so that let us can identify objects, and to make with that let us can be understood and to understand the others thus and, to be able to change experiences. It is the communicative function that in allows to the interaction and the convivncia them with the way, is important that they can be communicated of form that is understood what it wants to pass, without has interruption in the way as the ideals are displayed.
