Understanding Elaboration Likelihood Model:
The Elaboration Likelihood Model (ELM) is a theory in psychology and communication that explains how people are persuaded. It identifies two main routes through which persuasion occurs:
- Central Route (High Elaboration)
Definition: Persuasion through careful and thoughtful consideration of the arguments in the message.
Used when: The person is motivated and able to process the message.
Features:
Deep processing of information
Focus on logic, evidence, and reasoning
Leads to lasting attitude change
Example: A person reads a detailed research article before deciding which car to buy. - Peripheral Route (Low Elaboration)
Definition: Persuasion that occurs due to superficial cues rather than the strength of the message.
Used when: The person has low motivation or limited ability to process the information.
Features:
Shallow processing
Influenced by cues like attractiveness, credibility, or emotional appeal
Leads to temporary or weak attitude change
Example: Someone buys a product because a celebrity endorsed it, not because they researched its quality.
Factors Influencing Route Choice
Factor Central Route Peripheral Route Motivation High (e.g., personal relevance)Low (e.g., disinterest)Ability High (e.g., knowledge, focus)Low (e.g., distraction, fatigue)Need for Cognition High Low
Key Takeaways
The central route leads to stronger, more enduring attitude change.
The peripheral route works better for quick, low-effort persuasion.
Advertisers, educators, and politicians use both routes depending on their goals and audience.
