Partial test 1 week 5 ELM, SJT and cognitive dissonance Flashcards
Elaboration Likelihood Model (ELM) by …
Richard Petty and John Cacioppo
Main aim of the Elaboration likelihood model
To explain how an attitude change (persuasion) can take place by looking at peoples motivation and ability to think.
What is the ‘dual process model’ of ELM
People can process information in two ways; the central route and the peripheral route
What are the two factors that influence on which route someone processes new information?
- Motivation (are you willing to think?)
2. Ability (can you think?)
Explain what causes someone to have motivation to think about new information
- It has to be of personal relevance (characteristic of situation)
- The person has a need for cognition (characteristic of person)
Explain what causes someone to have ability to think about new information
- There should be no distraction (characteristic of situation)
- There has to be a certain level of intelligence or prior knowledge (characteristic of person)
Characteristics of processing information on the central route
- High elaboration likelihood
- Sufficient motivation and ability
- Thorough level of information processing
Characteristics of processing information on the peripheral route
- Low elaboration likelihood
- Insufficient motivation and ability
- Superficial level of information processing
How does someone on the central route get persuaded?
Strong arguments
How does someone on the peripheral route get persuaded?
By peripherals, like;
- The bandwagon effect
- The opinion of ‘experts’
- Brand coolness
What is the attitude outcome of someone that processed information via the central route?
When positive initial attitude; Strong positive attitude
When negative initial attitude and/or weak arguments; Strong negative attitude (boomerang effect)
What is the attitude outcome of someone that processed information via the peripheral route?
Weak positive or negative attitude that is easy to be changed or influenced
Explain ‘biased elaboration’
People already have given the topic a lot of thought and have already formed a very strong opinion, they are therefore extremely difficult to persuade.
What are the characteristics of a strong attitude?
- It is accessible
- It is persistent (will resist counter arguments
- It predicts someone’s behaviour
What are the characteristics of a weak attitude?
- Temporary
- Easy to change with counter arguments
- Difficult to predict behaviour based on a weak attitude
What is meant by the ‘continuum’ of the elaboration likelihood model?
It is not true that people can only use one of the two routes to process information. They are both on one extreme of a continuum and most people are somewhere along that continuum. So, they use a bit of the central route and a bit of the peripheral route to process their information.
Critique of elaboration likelihood model
It is difficult to establish what a ‘strong’ argument is, therefore the assumption that strong arguments persuade people is questionable. Next to that, the theory puts too much focus on the cognitive side of the brain and not enough on how emotions help us process information.
