The Yale Reinforcement Approach?
- research traces back to WW2
- described as “exposure to a persuasive communication that successfully induces the individual to accept a new opinion that constitutes a learning experience in which new verbal habit was acquired
- recipients would rehearse arguments of a message and form an attitude
- they will only accept the recommended attitude response if the incentives are greater than their original position
- incentives were recognised as rewards or punishments - THUS new incentives (reward-costs) must outweigh the old
To understand Persuasion - Lasswell said we must know “who says what to whom with what effect”
–> This includes factors such as:
1) credibility of communicator
2) features of the appeal i.e. fear arousing
3) persuasiveness of arguments
4) was attitude persuasion maintained over time?
Hovland at al added that to understand persuasion , it could be mediated through…
1) attention to the content of the communication
2) comprehension of the message
3) acceptance of the conclusions
What is Source effects?
- the impact of the source of a communication of persuasion
- Hovland used source effects to demonstrate how prestige a communication is to influence targets evaluation of the communication
Hovland also looked at impact of fear-arousing communication , what did he do and find?
- he looked at fear arousing communication on the acceptance of a recommendation that would reduce the threat
- DENTIST experiment –> fear threatened cancer, tooth decay (imagery) and infections
RESULTS = the weakest appeal was most effective BECAUSE of defensive avoidance - means that strongest fears were too threatening to accept and reduce initial fears
What are the 5 stages of Information Processing Model of McGuire?
1) attention
2) comprehension
3) acceptance
4) retention
5) behaviour
- said each stage of is necessary and required to progress, Persuade, and be effective
ALL require systematic processing because recipients need to read, understand and think about arguments in order for their to be an impact
- type of processing motivation likely to be used for complex/expensive products
McGuire also suggested that determinants of persuasion have different effects at different stages of persuasion process
He used a equation to simply his model, list each part and meaning
P(I) = P(R) x P(A)
P(I) = probability of a communication INFLUENCING attitudes (which relies on joint product of R x A
P(R) = probability of RECEPTION
P(A) = probability of of ACCEPTANCE/YIELDING
Rhodes and Wood looked at individual differences in INFLUENCE-ABILITY
- found that individual differences with moderate self-esteem to be more influences
- found only limited support for McGuire’s model
Greenwald and Petty’s Cognitive MODEL ?
- places importance on individuals thoughts “cognitive processes)
- passive listener from McGuires IPM replaced with active thinker (so silently discusses for / against arguments with the communicator)
A listener
-> active participant who relates communication to their own knowledge and they elaborate on message arguments
-> cognitive responses determine how well the arguments are remembered
Ohio State Group made 2 major contributions that made cognitive response into a testable theory…
1) the thought listening technique: PPs are asked to list all thoughts about a presentation. they are then made to eliminate irrelevant thoughts
- then thoughts are categorised by whether they are for or against communication
2) petty, wells and brock - proposed that cognitive responses to weak arguments reduces persuasion
- THUS strength of argument determines amount of persuasion and persuasion DEPENDS ON:
- - extent to which recipients engage in message relevant thoughts
- - favourability of these thoughts
How can Distraction ENHANCE persuasion?
- by impairing PPs ability to counter argue
- HOWEVER, distraction could also move one away from positive, well argued communication that could have led to attitude change
Petty et al tested role of distraction
HOW
PPs listened to well argued OR poorly argued counter attitudinal message (in favour of tuition fees)
- distraction task involved presentation of a visual stimulus (none - control, 15, 5 or 3 seconds)
RESULTS = increased attitude change for weakly argued message
RESULTS = decreased attitude change for stronger arguments
CONC: distraction impaired PPs ability to produce counter arguments for weak message BUT reduced number of favourable arguments for strong message
Cognitive response model assumes …
attitude change is always mediated by argument-relevant thinking
EVEN if the extent to which PPs think about the argument is minimal
Dual process Theories of persuasion
Is an extension of Cognitive response model that proposes …
1) persuasion can occur without much fault
2) specifies factors (moderators) that determine processing depth
What are the two Dual process mdoels?
1) Elaboration likelihood model by Petty et al
2) Heuristic-systematic model by Chaiken et al
