and Don'ts for Brief Research Talks
(borrowed from Gordon H. Bower)
1. A talk
is not a written Journal Experimental Psychology paper. Talks have
an informal narrative style and are dramatic rather than detailed or
completely informative. Don't read your "speech". Speak it
2. The model
for the short speech is the campfire story -- teller of a
mystery, (or a Steve Martin skit), not the recitor of an encyclopedia.
3. You must
be very selective of what you can say in a short time. Most
short speeches can barely carry one main idea plus its support. Resist
the temptation to tell everything you know or every thought you had
it: only the most interesting and important thing can be said.
4. Talk informally
as though you were telling your grandmother what you did
and why. Complexity of expression is uncorrelated with wisdom,
intelligence, and originality; it's perfectly correlated with audience
puzzlement and boredom.
5. A narrative
style is preferable in talks. Research is done to tell a
story, going from problem, goal, plan through actions (observations)
outcomes, resolution, and a moral (conclusion). Avoid a written
your first two sentences like they were a Madison-Avenue
advertisement for you and your talk. Grab the audience in these first
weak start: ``The research I will tell you about stems from
earlier work by Johnson published in Cognitive Psychology which led
lot of follow ups; and I want to thank my collaborators, Jim and Dorothy
(b) A better
start: ``How do we understand language'? How can I figure
out the meaning of what you say? Some people believe we have a mental
dictionary with fixed entries and we assemble the meanings out of this
fixed dictionary. Another theory is that we only have flexible procedures
which decompose compound phonetic strings into basic morphemes from
we compute a meaning for the utterance . . .''
7. Get interest
and attention first, with a rhetorical question, anecdote, or
startling statement or paradox. Assume your audience is an Introductory
Psych class of undergraduates.
8. In planning
your talk, consider these steps:
on paper slips ideas and points to be made.
them into an outline and fill it out.
the outline, concentrating on transition sentences between
out your speech as you speak it -- work on oral, not written
a new outline of the revised written version.
delivering the talk orally from the revised outline.
aloud before a mirror and with a clock in front of you.
Keep it to 12-14 minutes.
to give the talk with at most one 3x5 card of outline notes.
9. Use visual
aids (overhead transparencies or slides but not both) if they
help. In visuals, make it simple, clear and obvious. Don't clutter
slides with irrelevancies. No more than 7 words on a visual. No more
than 7 numbers on a visual (round them to one or two significant digits).
Slides must be readable; print large. One word can abbreviate whole
phrases. If you have lots of results you must show, use many slides,
not one cluttered slide. Idealize graphs, no lightning-bolt data.
Ask: are the exact values all that terribly important for my point?
10. Put up
a slide only a moment before you want to refer to it. Give the
audience time to read it or you read it to them. Remove the slide when
you want the audience to attend fully to you again.
11. If a
within-trial procedure is complicated, show a concrete illustration
of it in a visual. If the series of events in an experiment is long
complicated, show diagram of it.
12. In narrative
talks, descriptive and inferential statistics should be
suppressed. Speak "eyeball-effects" rather than F-values.
words were remembered very much better than those", NOT "The
for the two categories was 8.76 and 4.37, and difference gave an F of
13.8 which with 1 and 14 degrees of freedom was statistically significant
at the .01 level." A better attitude towards description is "Holy
baloney, look at that!"
13. State the problem being investigated in concrete, specific terms.
the audience understand specifics first before moving to generalities
(if you ever do).
exactly what responses your subject was making, perhaps give one
or more concrete illustrations of materials for different trial types.
That helps the audience instantiate the abstractions (you shouldn't
15. You are
not duty-bound to describe every condition of your experiment, not
every result, not every analysis. In particular, suppress complications
and unresolved loose-ends or incomprehensible pieces of results -- don't
lay your confusions on the poor listener. Your goal is to tell a simple
coherent story, to interest and to entertain, not to tell the complete
unvarnished messy truth. Your first rule is: tell a simple mystery story
that has a neat wrap-up and don't confuse or bore your audience. Not
telling the whole truth is not the same as telling a falsehood. Speeches
are for conviction, written papers for corrections!
your main idea and then clearly conclude. Make it completely
obvious to your audience exactly when you have finished, by some words
gestures (e.g., by stepping back, smiling and saying `Thank you').
Applaud one another at the end of his/her speech. (Ask -- Are there
any questions? Then wait a long time).
worry about "tough" questions: they almost never come. You
more about the research than anybody, so you have a great advantage.
Don't be intimidated by "big shots" in the audience (if there
most are struggling to comprehend, and ask only simple questions.
18. If a
question comes you don't know about, it's okay to say "I don't
Or to say "That's a tough one I haven't thought about -- or I'll

trying in an
experiment". You don't have to have instant answers for everything.
you don't understand a questioner, ask him to rephrase it so you can
understand. If he asks three questions, answer any one of them and move
at least one pithy question with a friend so he/she can direct it to
you in case no one else pops up with a quick question. Often the audience
needs time to think of some question to ask about -- so give the audience
a long time to come up with a question.

Speak loud enough.
