An Experimental Study of the Effects of Toulmin's Pattern for Argument Development on Attitude Change.
Reinard, John C.; Reynolds, Rodney A.
This research sought to determine the persuasive impact of Toulmin's categories of message development. Specific hypotheses were formulated after a review of the literature related to "backing for the warrant" (evidence), "rebuttal" (two-sided messages), and "qualifier" (message-receiver discrepancy). Results from a study of 120 college students indicated that the most persuasive form of message was that which employed backing and rebuttal (evidence and a two-sided message). Additionally, it was found that two-sided messages produced significant attitude change only when accompanied by evidence. (Author/AA)
