Persuasion • Attitude change through communication
Elaboration Likelihood Model (Petty & Cacioppo, 1986) • Central route processing –persuasion depends on the logic, merit, or strength of the arguments. • Peripheral route processing- persuasion depends on cues unrelated to the strength or quality of the arguments.
Elaboration Likelihood Model • Central route leads to more enduring attitude change. • For central processing to occur, the recipient must be motivated and able to analyze the message content.
