College 4 Flashcards
What do you need to know in order to understand persuasion?
- Who says What?
- In what Channel?
- To Whom?
- And with what effect?
Who (speaker) + What (message) + Channel (medium) + Whom (audience or listener) = Effect
What are the three theories of persuasion?
- McGuire’s information processing model
- Cognitive response model
- Dual process models
The first two models are relevant to advertising for history of theorizing; to see where different elements in current theories come from.
McGuire’s information processing model.
This looks very similar to the DAGMAR model.
The idea is that people go through different stages when they process a message.
Exposure/presentation => attention/awareness => comprehension/understanding => acceptance => retention => action (eacara)!
This goes from easiest to hardest.
Persuasion attempts can have different effects at different stages.
What are the assumptions of McGuire’s information processing model? And are these still true?
Hierarchical model:
- People must go through each of the steps before behavior change occurs.
- However, skipping steps is also possible.
Systematic processing is required.
- However, persuasion can occur without systematic processing. We also see effects with superficial processing.
Learning of the message is essential for persuasion.
- However, little scientific support for this assumption.
Is McGuire’s information processing model still used?
Yes, even though this theory is criticized, people still use this a lot.
Cognitive response model
In contrast with the McGuire model, the receiver is active in the cognitive response model.
- So there is more going on than passive acceptance.
- Thoughts are also important for persuasion.
The receiver relates message with existing information.
- Mainly favorable thoughts about message => intended change.
- Mainly unfavorable thoughts about message => unintended change/ no change.
The most important product of this model is the thought listing technique.
The thought listing technique
- You ask people to list all the thoughts they had during the message presentation.
- You categorize relevant thoughts as favorable/unfavorable.
- You create index. Based on that you can have an idea about the attitude towards the advertisement.
How does the strength of arguments influence the cognitive response model?
Strong arguments => favorable thoughts => intended change.
Weak arguments => unfavorable thoughts => unintended change/no change.
However:
- Effects of argument strength on thoughts disappear when distracted (i.e., systematic processing required).
- People often do not think about advertising as deeply as this model suggests.
Dual process models
Elaboration Likelihood Model (ELM)
Heuristic Systematic Model (HSM)
These are different but we will treat them as equal.
What do ELM and HSM have in common?
Information is being processed systematically or superficially.
Different words for the same processing logic:
- Central/systematic
- Peripheral/heuristic
Processing more depends on: ability and motivation.
How can a dual processing model have influence on ads?
You have to differentiate between the heuristic cues (e.g., celebrity) and systematic cues (strong arguments).
Depending on the processing you will be influenced more by the one or the other. It can also be a combination of both.
Some message cues can be seen as an argument or as a heuristic.
What predicts ability?
- Knowledge:
- If you have more knowledge, you can think about it more carefully. You can also process it more deeply. - Distraction/time pressure
- The more distracted you are, the more time pressure you feel and the more you will go for it. - Repetition
- The more often you see an ad, the higher the chances are that you process the message correctly.
Knowledge in the role of processing ability
Knowledge: better able to process a message systematically.
Wood et al. (1985) on knowledge in the role of processing ability
Counter-attitudinal message against preservation of environment.
- 3 groups based on the knowledge of students (based on pretest).
- Strong arguments vs. long argument (i.e., systematic vs. heuristic cue)
Effects on attitudes:
- Argument strength more effect on most knowledgeable students.
- Argument length more effect on least knowledgeable students.
Distraction/time pressure in the role of processing ability
When you are under a lot of time pressure => more likely to process with heuristics, because you don’t have the time to evaluate all the messages. You will go for a low processing intensity.
Low processing intensity => more likely to use heuristics.
Important for advertisement because of multitasking: less attention for ads => more likely heuristic processing.
But is a second screen always a bad thing?
Repetition in the role of processing ability
It’s a wise strategy in the beginning.
More repetition => more ability to process.
However, too much repetition can result in wear out/irritation. Particularly with more systematic processing.
Possible solution: variation in advertising
- Different lay-out
- Different message content
What can influence motivation?
Individual differences in processing motivation.
- Some people have a need for cognition
- Some people have a need to closure (they just want a conclusion)
Motivation is greater when something is seen as personally relevant.
- When something relates to values, goals and needs.
- When people are prone to considerable risk => Fear appeals
Experiment by Petty et al. (1983) on the role of personal relevance and strong or weak arguments
They devided the participants into two groups:
- High personal relevance
- Low personal relevance
It was about a razor.
The participants heard either a strong or weak argument. Then they put the razor with either a famous or non-famous endorser.
Most positive attitude towards razor:
- High personal relevance => strong arguments
- Low personal relevance => famous endorser
Fear appeals
You can create a problem to induce fear. E.g., if you have a bad breath you will never be a bride.
The idea is that you will buy the product so can overcome the feeling of fear.
Now more often used in health campaigns than commercial advertising.
Experiment by Cartocci et al. (2019) on a neuroscientific application of fear appeals
They measured two EEG indexes of these two ads:
- Mental engagement index (ME): effort during a vigilant task.
- Approach/withdrawal index (AW): positive (vs. negative) motivation to approach (vs. withdraw) a specific object.
Results suggested that the ME and the AW presented an opposite trend:
- Smokers showed higher ME and more negative emotions (AW) than nonsmokers.
