Persuasive Effects of Sales Messages Developed from Interaction Process Analysis
In a field experiment three salesman employed six alternative messages in attempting to sell a magazine subscription to student subjects randomly selected from the registrar's listing at a major university. Three conversational and three nonconversational messages, developed from Bales's Interaction Process Analysis, were employed in a telephone selling paradigm, designed to minimize extraneous nonverbal communication. Each salesman contacted prospective subjects (n = 78, 73, 118) until he had completed 42 sales attempts, 7 per message, for which a postquestionnaire was administered.
