Likelihood

The elaboration likelihood model (ELM) of persuasion, developed by Richard Petty, John Cacioppo, and their collaborators, is an example of a “dual process” approach to persuasion (another example is Chaiken’s heuristic-systematic model, HSM). The ELM suggests that important variations in the nature of persuasion are a function of the likelihood that receivers will engage in

Elaboration Likelihood Model Definition The elaboration likelihood model (ELM) of persuasion is a theory about how attitudes are formed and changed. This theory organizes the many different attitude change processes under a single conceptual umbrella. The ELM was created to provide a framework to help explain the many seemingly inconsistent findings in the persuasion literature.
