Transcript of Student CM 380 ELM

Receiver-based Theories
Elaboration Likelihood Model
Cognitive Dissonance
Social Judgment Theory
Cognitive Dissonance
Elaboration Likelihood Model
Social Judgment Theory
When an individual holds two inconsistent cognitions
= that individual experiences discomfort
motivated to reduce discomfort
Expenditure of Effort
The extent to which an individual (receiver) engages in message-relevant thinking.
Ways for receiver to elaborate:
Ability to elaborate
trait or state

Motivation to elaborate
involvement level (high = central, low = peripheral)
need for cognition

Additional keys to ELM:
persistence of persuasion
channel selection
How individuals compare a message (i.e., position) to their beliefs/attitudes/values (i.e., anchor)
Source's positions fall within a receiver's:
Latitude of acceptance
Latitude of rejection
Judgment Distortions
Lat of Accept Noncom Lat of Reject
0-$9,000 $9,001-$9,999 $10,000
Car dealership: attempt to maximize position (price) while appealing to the buyer's anchor
Cover Ads
Colbert Report: 2:21
Climate Change change
Video: Friends - Pottery Barn
Ways to reduce dissonance:
Create dissonance then reduce dissonance
Effectiveness of Boot Camp, Hazing, etc.
Gun Control Debate
*often seen as the most important factor in the model
*incremental changes rather than gun/no gun debate
Attitude change
Ego involvement
Implications for communicators
Message must fall within latitude of acceptance/latitude of noncommitment
(beware boomerang effect)
Politician vagueness
modifying: behavior or attitudes
Receiver variables:
Central Cues: strength of argument
Peripheral Cues: heuristics or scripts
lists of "pseudo-evidence"
ELM goal:
To match receiver's likely processing route with appropriate cue
Central route: deep thought
Peripheral route: superficial
Influences of elaboration
expert testimony
NOTE: model does not address changing receiver's processing
