Com Arts Exam #2 Flashcards
the materials used to support a speaker’s ideas. The 3 major kinds of supporting materials are examples, statistics, and testimony.
supporting materials
make speeches more interesting and convincing. They are sharp and specific, clear and credible
supporting materials
a specific case used to illustrate or represent a group of people, ideas, conditions, experiences, or the like
example
a specific case referred to in passing to illustrate a point (pile them one upon the other until you create the desired impression)
brief example
a story, narrative, or anecdote developed at some length to illustrate a point (tell story vividly and dramatically)
extended example
an example that describes an imaginary or fictitious situation (speaker creates a realistic scenario, relates it directly to her listeners, and gets them involved in the speech)
hypothetical example
use examples to personalize your ideas, reinforce examples with statistics or testimony, make your examples vivid and richly textured, and practice delivery to enhance your extended examples
tips for using examples
numerical data
statistics
why is it easy to lie with statistics?
they can be easily manipulated and distorted
are the statistics representative? are statistical measures used correctly? and are the statistics from a reliable source?
questions you should ask to judge the reliability of statistics
the average value of a group of numbers
mean
the middle number in a group of numbers arranged from highest to lowest
median
the number that occurs most frequently in a group of numbers
mode
use statistics strategically, identify the sources of your statistics, explain your statistics, round off complicated statistics, and use visual aids to clarify statistical trends
tips for using statistics in speeches
quotations or paraphrases used to support a point
testimony
testimony from people who are recognized experts in their fields
expert testimony
testimony from ordinary people with firsthand experience or insight on a topic
peer testimony
testimony that is presented word for word
direct quotation
to restate or summarize an author’s ideas in one’s own words
paraphrase
quoting a statement in such a way as to distort its meaning by removing the statement from the words and phrases surrounding it
quoting out of context
quote or paraphrase accurately, use testimony from qualified sources, use testimony from unbiased sources, and identify the people you quote or paraphrase.
tips for using testimony
the book, magazine, newspaper, or web document you are citing; the author or sponsoring organization of the document; the author’s qualifications with regard to the topic; and the data on which the document was published, posted, or updated.
the pieces of info you must provide when making oral citations in a speech
the name used by Aristotle for what modern students of communication refer to as credibility
ethos
the audience’s perception of whether a speaker is qualified to speak on a given topic. The two major factors influencing a speaker’s credibility are competence and character.
credibility
the credibility of a speaker before they start to speak
initial credibility
the credibility of a speaker produced by everything they say and do during the speech
derived credibility
the credibility of a speaker at the end of the speech
terminal credibility
explain your competence, establish common ground with your audience, and deliver your speeches fluently, expressively, and with conviction
ways to enhance your credibility during speeches
a technique in which a speaker connects themselves with the values, attitudes, or experiences of the audience
creating common ground
supporting materials used to prove or disprove something
evidence
Persuasive speakers need to use evidence because
most people are skeptical and suspicious of unsupported generalizations. They want speakers to justify their claims.
use specific evidence, use novel evidence, use evidence from credible sources, and make clear the point of your evidence
tips of using evidence effectively
the name used by Aristotle for the logical appeal of a speaker. The 2 major elements of logos are evidence and reasoning
logos
the process of drawing a conclusion on the basis of evidence
reasoning
reasoning that moves from particular facts to a general conclusion
reasoning from specific instances
It is important to supplement reasoning from specific instances with testimony or statistics because
you can never give enough specific instances in a speech to make your conclusion irrefutable, so you should use them to demonstrate that the instances are representative.
reasoning that moves from a general principle to a specific conclusion. It is the opposite of reasoning from specific instances: it moves from the general to the specific
reasoning from principle
reasoning that seeks to establish the relationship between causes and effects
Causal reasoning
The relationship between causes and effects are not always clear because
the fact that one event happens after another does not mean that the first is the cause of the second; the closeness in time of the 2 events may be entirely coincidental
reasoning in which a speaker compares 2 similar cases and infers that what is true for the first case is also true for the second
analogical reasoning
Analogical reasoning is frequently used in persuasive speeches on questions of policy because
when arguing for a new policy, you should find out whether it has been tried elsewhere—you may be able to claim that your policy will work because it has worked in like circumstances
an error in reasoning
fallacy
hasty generalization, false cause, invalid analogy, bandwagon, red herring, ad hominem, either-or, slippery slope, appeal to tradition, and appeal to novelty
10 logical fallacies
a fallacy in which a speaker jumps to a general conclusion on the basis of insufficient evidence
hasty generalization
a fallacy in which a speaker mistakenly assumes that because one event follows another, the first event is the cause of the second
false cause
an analogy in which the 2 cases being compared are not essentially alike
invalid analogy
a fallacy which assumes that because something is popular, it is therefore good, correct, or desirable
Bandwagon
a fallacy that introduces an irrelevant issue to divert attention from the subject under discussion
Red herring
a fallacy that attacks the person rather than dealing with the real issue in dispute
Ad hominem
a fallacy that forces listener to choose between 2 alternatives when more than 2 alternatives exist
either-or
a fallacy which assumes that taking a first step will lead to subsequent steps that cannot be prevented
slippery slope
a fallacy which assumes that something old is automatically better than something new
appeal to tradition
