Chapter 5 Flashcards
Persuasion
Any change in beliefs and attitudes that results form exposure to a
communication.
The Yale Reinforcement Approach
Hovland founded the Yale Communication and Attitude Change Program after WWII
Yale Reinforcement Approach: Exposure to a persuasive communication that
successfully induces the individual to accept a new opinion constitutes a learning
experience in which a new verbal habit is acquired.
o Recipients of a persuasive message would silently rehearse the arguments
together with the recommended response and their own initial attitude
o They will only accept the recommended attitudinal response if the incentives
associated with this response are greater than those associated with their own
original position
Communication and Persuasion
o In order to understand persuasion, one must know “who says what to whom
with what effect”
o Innovative experimental research on the impact of communicator credibility,
on features of the communication such as fear-arousing appeals or the
organization of persuasive arguments, on individual differences in
susceptibility to persuasion and on the extent to which attitude change was
maintained over time
o The impact of any of these factors on attitudes could be mediated by three
different processes:
1. Attention to the content of the communication
2. Comprehension of the message
3. Acceptance of the conclusion advocated by the communication
Source effects: The impact of the source of a communication on persuasion.
o Attribution of a communication to either a prestigious or a non-prestigious
source influenced the target’s evaluation of the communication
Fear-arousing communication
o The weakest appeal was most effective in changing attitudes and behavior
o Defensive avoidance: The strong fear appeal was so threatening that it was
more effective for recipients to reduce fear by rejecting the appeal as alarmist
rather than accepting the recommendation.
o Findings have rarely been replicated in later research; actually, reverse effect
has been found

The information processing model of McGuire
Information processing model: (1) There are different stages involved in the processing
of persuasive communications and (2) determinants of persuasion could have different
impacts at different stages
Five stages of persuasion:
1. Attention
2. Comprehension
3. Acceptance
4. Retention
5. Behavior
The receiver must go through each of these steps if the communication is to have an
ultimate persuasive impact, and each depends on the occurrence of the preceding
step
One has to question whether recipients really have to go through these steps for the
advertisement to be effective
o There are a variety of ways by which messages can influence, even without
having been carefully processed
o Processing motivation is likely to be higher for more complex and expensive
products
The probability of a communication influencing attitudes [P(I)] is the joint product of
the probability of reception [P(R)] and acceptance [P(A)]
o P(I) = P(R) × P(A)
McGuire stated that most personality characteristics have opposing effects on
reception and acceptance
o People are more likely to understand a message the more intelligent they are
o More intelligent people are also likely to be more critical and therefore less
likely to accept everything they hear or read
Curvilinear relationship of reception and acceptance, with the maximum level of
influenceability found at some intermediate level for the personality characteristic
A meta-analysis of studies of individual differences in influenceability provided limited
support for the McGuire model

of persuasive communications and (2) determinants of persuasion could have different
impacts at different stages.

The cognitive response model
The cognitive response model was developed by Greenwald, Petty, and their
colleagues partly to explain the frequent failure to find a correlation between
argument recall and attitude change, despite evidence that recipients had
systematically processed the message arguments
The model stresses the importance of the thoughts individuals generate – and thus
rehearse and learn – in response to a persuasive communication
Listeners are active participants who relate the communication to their own
knowledge
o Generating thoughts for and against the arguments presented
o The cognitive response to the message arguments produced by the recipient,
rather than the message arguments themselves, determine the impact of the
persuasive communication on attitudes
Thought-listing technique: Subjects are asked to list all the thoughts or ideas they had
while listening to the communication. After elimination of thoughts that are irrelevant
to the communication, the relevant thoughts are then categorized by participants or
external raters into those that are favorable to the position advocated by the message
and those that are generally unfavorable. An index based on these thoughts can then
be used to assess the extent to which cognitive responses mediated the impact of a
communication on attitudes.
With strong and well-reasoned arguments, thinking about them might in fact reduce
our reluctance to change our minds
Although cognitive responses to weak arguments would reduce persuasion, thinking
about strong and well-reasoned arguments would produce favorable thoughts that
would enhance persuasion
Since recipients process messages more or less intensively, persuasion should depend
on both:
o The extent to which recipients engage in message-relevant thoughts
o The favorability of these thoughts
Distraction
o Until it begins to interfere with reception, distraction should enhance
persuasion by impairing a recipient’s ability to counterargue
o The persuasion-reducing effect of distraction was not necessarily due to
impairment of comprehension but due to impairment of the ability of
recipients of a well-argued communication to produce positive thoughts that
might have persuaded them to change their attitudes
o Increased distraction increased attitude-change for weakly argued messages,
but decreased change for strongly argued message

o The favorability of these thoughts
Dual process theories of persuasion
Dual process theories of persuasion
o They acknowledge that recipients may sometimes take shortcuts and accept or
reject the position recommended by the communicator without thinking about
message arguments
o They specify the factors that determine the intensity of message processing,
and thus the conditions under which attitude change will be mediated by
message-relevant thinking
Elaboration Likelihood Model (ELM)
Heuristic-Systematic Model (HSM)
Two routes to persuasion:
1. Systematic processing: Recipients carefully and thoughtfully consider the
arguments presented in support of a position.
2. Heuristic processing: The use of simple decision rules in deciding on whether to
accept or reject a persuasive communication.
Two types of qualitatively different information that message recipients use when
trying to decide whether to accept or reject the position advocated by a
communicator:
1. Arguments contained in the information
2. Heuristic cues
Message arguments offer better and more reliable evidence for the validity of a
position advocated by a communicator than heuristic cues, but heuristic cues are
easier to process
Processing motivation is important because unless an issue is relevant to participants,
they will not expend much effort in thinking about arguments for or against the issue
Processing ability is important because in order to judge the validity of the arguments
contained in a communication, a person needs knowledge, time, and peace of mind
It was originally assumed that the two processing modes are compensatory; more
recently, it has been suggested that the two modes of processing can co-occur, if
systematic processing of arguments does not allow one to arrive at a clear-cut
conclusion
Variables can affect persuasion in multiple ways, depending on the extent to which a
message is processed systematically
Multiple-role assumption: Depending on the level of processing motivation, the
attributes of an endorser of a product can be used as a heuristic cue to influence
attitude towards a product, but they can also serve as an argument.
The extended dual process framework incorporates two further processing motives or
goals:
1. Defense motive
-Need for positive self-regard
- Vested interests
- Attitudinal commitment
- Need for consistency
- Impression motive
- Desire to express attitudes that are socially acceptable
-Assessing the social acceptability of alternative positions in order to
accept attitudinal positions that will please or appease potential
evaluators
Defense-motivated as well as impression-motivated processing can be heuristic as
well as systematic
Assessing the intensity of processing
Two strategies for assessing processing intensity:
1. Thought-listing
2. Manipulation of argument quality
If attitude change is due to systematic processing, then (thought-listing):
o Recipients should have generated some thoughts favorable to the position
advocated by the communicator
o The relative favorability or unfavourability of these thoughts should be
correlated with the amount of attitude change
o A favorability index (the ratio of favorable thoughts to total number of relevant
thoughts) should act as a mediator of the impact of the manipulated variables
on attitude change with systematic but not under heuristic processing
Manipulation of argument quality
o Persuasive appeals containing strong arguments should stimulate mainly
favorable thoughts in recipients who engage in systematic processing, and
result in substantial attitude change
o Weak arguments should trigger mainly negative thoughts and fail to result in
attitude change or even result in negative change (i.e. boomerang effect)
Boomerang effects have never been observed empirically
