B. Thinkers like Aristotle and Plato used the word rhetoric to mean using any and all
“available means of persuasion” in public speeches
1. Argument: articulating a position with the support of logos, ethos, and pathos
2. Logos: a persuasive strategy of constructing logical arguments that support your
position
3. Ethos: a persuasive strategy of highlighting your competence, credibility, and
good character as a means to convince others to support your position
4. Pathos: a persuasive strategy of appealing to emotions in order to convince
others to support your position
C. Processing Persuasive Messages
1. The Elaboration Likelihood Model (ELM) to explain how likely people are to spend
more or less time critically evaluating information before making their decisions
2. Central route: we listen carefully, reflect thoughtfully, and maybe even mentally
elaborate on the message before making a decision
3. Peripheral route: a shortcut that relies on simple cues, such as a quick evaluation
of the speaker’s competence, credibility, and character (ethos), or a gut check
about what we feel (pathos) about the message
D. Characteristics of central route processing
1. If the issue is more important to us, we take the central route
2. We are less likely to change our minds when we form attitudes as a result of
central route processing, as beliefs are more strongly held
3. Persuaded by sound reasons and critical analysis
E. Characteristics of peripheral route processing
1. If the issue is less important to us, we take the peripheral route
2. We are less committed to attitudes formed using the peripheral route
3. Persuaded by more emotional appeal coming from a credible source
II. Writing persuasive speech goals as propositions: a declarative sentence that clearly
indicates the speaker’s position on the topic
A. Types of propositions
1. Questions of fact: designed to convince an audience that something is or is not
true or does or does not exist
2. Questions of value: designed to convince your audience that something is good,
bad, desirable, undesirable, fair, unfair, etc.
3. Questions of policy: designed to convince that they should take or support a
specific course of action
B. Tailoring your proposition to your audience
1. The target audience is the group of people you most want to persuade
2. Opposed
a. Strong opposition: move the audience closer to your position, but don’t
expect a complete change in your direction
b. Mild opposition: understand their resistance and present strong arguments to
support your position, including evidence to counter other attitudes
3. No opinion
a. Uninformed: not knowing enough about a topic to have formed an opinion;
provide basic arguments and information
