Its main representatives are Leonard Bloomfield (the head), Charles Fries, Zelic Harris, Charles Hockett, etc. They rejected the traditional techniques of linguistic analysis. They studied the non-alphabetical incorporative languages of Indian tribes which differ considerably from Indo-European languages. These linguists offered new procedures of description (arrangement, position, co-occurrence of linguistic elements) without resorting to meaning. Hence this school is called, at times, Behaviorist Structural Grammar (L. Bloomfield). According to behaviorists, language is just a form of behavior. Linguistics should focus on linguistic performance, it should study the behavior, distribution, arrangement, co-occurrence, structural characteristics of elements disregarding their meaning.
