Intellectual skills are dissociated from language skills.

The social life of human beings is based on their ability to interact with their fellows through language.

People speak to be "heard", sometimes to be respected and also to exert an influence on the environment in which they perform linguistic acts.

Each individual, when is using the language, not only says what he thinks, but also acts in people, aiming to influence certain attitudes or behaviours.

Interaction and language are elements that complement each other.
