This paper reports the analysis of the verbal output of 20 two-man teams who communicated through four different channels to solve problems cooperatively. Each word of the protocols was assigned to one of six linguistic classes based on Friess analysis of the structure of English. Results indicate significant shifts in the relative proportions of the different classes of words as a function of mode of communication. Subjects communicating by voice on the average use more pronouns and more function words than do subjects who write or typewrite. Subjects who handwrite on the average use fewer pronouns and fewer verbs and verb derivatives than do subjects in all other modes of communication. Author
