Based on accumulated knowledge concerning the effects of language intensity on attitude change, a set of propositions were advanced that provide a skeletal theoretical framework. Based on the propositions, three separate studies were done to extend the predictive power of the formulation. Predicted interactions between sex of the source, situational anxiety, source credibility, and language intensity were obtained. There were also significant person perception changes as a result of the level of language intensity employed in the persuasive message. Discussion centered on the import of the new findings in formulating a message-centered theory of persuasion.
