The author reports on an investigation of the variations in total verbal output and in verbal variety noted from interview responses of eighteen persons, each involved with a specific issue or topic at one of three levels. He defines the levels as: (1) observer, or someone who is aware of the issue but passive about it; (2) participant, or one who actively engaged in work for or advocacy of the issue; and (3) coordinator, who not only advocates or works for the issue, but also enlists and coordinates the activities of others. All subjects responded to the same questions and were allowed as much time as they wanted to respond. The interviews were transcribed and the content analyzed on a word-by-word basis. The author reports that the results revealed a geometric increase in total verbal output and in verbal variety as commitment increases. He also discusses his analysis of items such as types of words used and functions of certain words for each of the levels, and he points out some of the clear differences among the semantic qualities of the most often used words elicited from subjects at the three levels of commitment.
