Oral Comm 17- Persuasion
Transcript of Oral Comm 17- Persuasion
"the process of changing, reinforcing or creating
an audience's beliefs, attitudes, values or behavior."
Ethos- refers to a speakers credibility.
A public speaker should be ethical, possess good character, have common sense, and care for the audience.
Credibility- audience perception of
whether a speaker is qualified. Both
implicit and explicit credibility.
Logos- refers to logic and reasoning.
A public speaker should make logical and rational arguments with evidence to support points.
Never ever fabricate evidence
to make a point. Instead, change your viewpoint.
Pathos- refers to appeals to emotion.
A public speaker should not use emotion to persuade unless its subtle and genuine.
Emotions could include
fear, guilt, pride, and sex appeal.
False Cause- assumes that because one event follows another, the first event is the cause of the first.
"Post Hoc Ergo Propter Hoc"
Slippery Slope- assumes that taking the first step will lead to subsequent steps that cannot be prevented.
Inductive reasoning- "uses specific instances to reach a general conclusion."

from a general statement to specific conclusion."

distract someone from the actual issue.
Invalid Analogy- when two things are compared
are not actually alike.
Bandwagon- reasoning that suggests because
everyone believes something than it must be valid.
Either/Or - The oversimplification of
an issue to a choice between two outcomes.

information about the person, not the
argument or idea itself.
