Assignment
What are the four tips for using
examples in your speech?
Explain the
difference between expert testimony and peer
testimony.
Supporting your ideas
Heather Kolpin decided to give her
first classroom speech on the benefits of good
nutrition. A
dedicated fitness
enthusiast, she had recently switched to a high-
protein diet. Part of her speech
ran
like this:
“
For years
we
?
ve been told that meat,
eggs, and cheese are bad for us and that we should
eat
more
carbohydrates
like
cereal,
grains,
pasta,
and
rice.
But
too
many
carbohydrates
can
unbalance the body and make you tired
and overweight. Do you want more energy? Do you
want
to concentrate better and get
higher grades? Do you want to enjoy real meals and
still lose those
unsightly
pounds?
If
so,
you
should
eat
more
protein.
I
?
ve
been
on
a
high-protein
diet
for
six
months,
and I
?
ve never felt better
or done better in my
classes!
”
After the
speech, Heather
’
s classmates
were interested but skeptical. As one
remarked
,
“
I
know high-
protein diets are popular right now, but Heather
is no expert on nutrition. Besides, there
are lots of diets around, and they all
claim to work wonders. Personally,
I
’
d be more convinced if
Heather gave some scientific evidence
to back up her opinion.
”
Good
speeches
are
not
composed
of
hot
air
and
generalizations.
They
need
strong
supporting
materials
to
bolster
the
speaker
’
s
point
of
view.
In
Heather
’
s
case,
although
there
is
plenty
of
evidence on the need to
balance protein and carbohydrate consumption, many
nutritionists have
warned
about
the
dangers
of
overloading
on
protein.
So
Heather
’
s
listeners
were
right
to
be
skeptical. Heather made a mistake of
generalizing from her own experience with nothing
concrete
to support her ideas.
The
problem with generalizations is that they do not
answer the three questions listeners always
mentally ask of a speaker:
“
What do you
mean?
”
,
“
Why should I believe
you?
”
“
So
what?
”
The skillful use of
supporting materials often makes the difference
between a poor speech and a
good one.
Using supporting materials is not a matter of
tossing facts and figures into your speech.
You
must
decide
which
ideas
need
to
be
supported
given
your
audience,
topic,
and
specific
purposes.
You
must
do
research
to
find
materials
that
will
bring
your
ideas
across
clearly
and
creatively. And you must evaluate your
supporting materials to make sure they really do
back up
your ideas.
As
you
put
your
speeches
together,
you
will
need
to
make
sure
your
supporting
materials
are
accurate,
relevant,
and
reliable.
You
will
find
yourself
asking
such
questions
as,
“
Are
my
examples
representative?
”
,
“
Am I quoting reputable,
qualified sources?
”
There are three kinds of supporting
materials we use most often, they are: examples ,
testimony
and statistics
I
.
Examples
Examples
:
a specific case used to illustrate or
to represent a group of people, ideas, conditions,
experiences or the like.
In
the
course
of
a
speech
you
may
use
brief
examples
—
specific
instances
referred
to
in
passing
—
and
sometimes you may want to give several brief
examples in a row to create a stronger
impression.
Extended
examples
—
often
called
illustrations,
narratives,
or
anecdotes
—
are
longer
and more detailed.
Examples
are
useful
when
you
wish
to
make
an
abstract
concept
or
idea
concrete.
For
example, it is difficult for the
audience to see exactly what you mean by such
abstract concepts as
persecution,
denial of freedom, friendship, and love unless you
provide specific examples of what
you
mean.
Here is one example a student
used in a speech about lead poison.
?When
Denise Waddle and her
family moved to a nice, middle-class section of
Jersey City, New
Jersey, they had
dreams of healthy living, block parties, even a
big backyard so their kid could
make
mud pies. In less than one year in their new home,
their two-year-old son had been poisoned,
and their newborn showed high levels of
poisoning in his bloodstream. Unknowingly, the
Waddle
?
s
had been
poisoned by their own backyard, for high levels of
lead contaminated their water and
their
lives.
”
Examples
may be real and factual on one hand or
hypothetical and
imagined on the other.
The hypothetical and imagined ones are
called hypothetical examples.
Hypothetical example
: an
example that describes an imagery or fictitious
situation
Here is one student used a hypothetical
example to
illustrate the need for
college students to
protect themselves
against crime:
Y
ou
’
re
tired;
you
’
re
hungry.
You
’
ve
just
spent
a
long
day
at
College
Library
and
you
cannot
wait to get back to your room. Glancing outside,
you remember how quickly it becomes
dark. You don
’
t
think much of it, though, as you bundle up and
head out into the gusty wind. Not
until
you spy the shadows on the sidewalk or hear the
leaves rustling beside you do you wish you
weren
’
t alone.
You walk quickly, trying to stop your imagination
from thinking of murderers and
rapists.
Only when you are safely inside your room do you
relax and try to stop your heart from
pounding out of your chest.
Can you
remember a time when you felt this way? I would be
surprised if you never have. The
FBI
reported
last
year
that
there
were
three
murders,
approximately
430
aggravated
assaults,
1400
burglaries,
and
80
rapes
here
in
Madison
alone.
And
while
these
statistics
are
quite
alarming, they
don
’
t compare to the numbers
of larger metropolitan areas.
This
hypothetical
example
is
particularly
effective.
The
speaker
creates
a
realistic
scenario,
relates
it
directly
to
her
listeners,
and
gets
them
involved
in
the
speech.
In
addition,
she
uses
figures
from
the
FBI
to
show
that
the
scenario
could
really
happen
to
any
of
her
classmates.
Whenever you use
a hypothetical example, it is a good idea to
follow it with statistics or testimony
to show that the example is not far-
fetched.
Tips for using
examples
1
.
Use
examples to clarify your ideas
Examples
are
an
excellent
way
to
clarify
unfamiliar
or
complex
ideas.
This
is
why
so
many
teachers
use
examples
in
the
classroom.
Examples
put
abstract
ideas
into
concrete
terms
that
listeners can easily understand.
This principle
works exceptionally well in speeches. Suppose you
are talking about suspension
bridges,
you could give a technical description
The suspension
bridge has a roadway suspended by vertical cables
attached to two or more
main cables.
The main cables are hung on two towers and have
their ends anchored in concrete or
bedrock.
If your listeners were made
up of people familiar with structural systems,
they might be able to
visualize what a
suspension bridge looks like. But for listeners
lacking this background, you might
want
to add a simple example:
Two well-known suspension
bridges are the Golden Bridge in San Francisco and
the Brooklyn
Bridge in New York.
Because almost everyone has
at least seen a picture of the Golden Bridge in
San Francisco and the
Brooklyn
Bridge
in
New
York,
using
them
as
examples
clarifies
your
meaning
quickly
and
effectively.
2. Use examples to reinforce your ideas
In a speech entitled
“
Boxing: The most dangerous
sport
”
, the speaker argued
that professional
boxing should be
banned. To reinforce his point, he cited the
example of Muhammad Ali, who
suffers a
severe case of Parkinson
’
s
disease brought on by his years in the ring. The
example is
very effective. It put the
medical facts about boxing and brain damage in
vivid, human terms that
everyone could
understand.
When
you
use
examples,
make
sure
it
is
representative.
The
example
of
Muhammad
Ali
is
quite representative.
3. Use examples to
personalize your ideas
People are interested in
people. AS social psychologist Eliot Aronson said,
“
Most people are
more deeply influenced by one clear,
vivid, personal example than by an abundance of
statistical
data.
”
Whenever you talk, you can
include examples that will add human interest to
your speech.
SEE
WHICH OF THE FOLLOWING WOULD YOU BE MORE LIKELY TO
RESPOND
TO
?
There
are many hungry families in our community who
could benefit from food donations
.
Or:
Let me tell you about
Arturo. Arturo is four years old. He has big brown
eyes and a mop of black
