ABSTRACT
Language always considers to linked to thought and to communicate information about the world. The functional separation of language and nonverbal behaviour is something of an established orthodoxy in psychology. The focus on nonverbal behaviour, as the significant domain through which human emotion is expressed, relationships are built and interpersonal attitudes are negotiated, has a long and distinguished history in psychology and in related disciplines. Wilhelm von Humboldt's famous dictum was that language provides a finite means for generating an infinite variety of expressive forms. The traditional view of the function of nonverbal communication is that it does not communicate semantic information about the world, but signals emotional state and attitudes crucial to the forming and development of interpersonal relationships. In human social behaviour it looks as if the nonverbal channel is used for negotiating interpersonal relations while the verbal channel is used primarily for conveying information.
