If you did not see the Republican Presidential debate the
other night, you have probably heard by now about candidate Rick Perry’s “brain
freeze” moment during the debate. No matter what side of the political spectrum
you fall on, it was painful to watch.
The point of this entry is not to examine this issue from a
political perspective but to look at it from a
neuropsychological perspective
and present ways to prevent something like this happening to you if you need to
give an oral presentation without Powerpoint slides. If you have not seen the
video or do not care to, Perry was not able to name the third of three federal
government agencies that he stated he would eliminate. The first was the
Department of Education. The second was the Department of Commerce. And the
third was…ummmm….the third was….Ooops. See for yourself here:
I have done a great deal of group presentations in my life.
Most of them involve use of Powerpoint slides in my professional career, which
allow you to easily reference information so you do not need to solely rely on
your memory. However, sometimes you need to make the off the cuff remarks when
responding to questions and other times you need to do a more spontaneous
presentation of information in life (e.g., best man speech, accepting an award,
presenting to a group over a teleconference).
One thing I try to (unless I know the topic in detail) is
avoid citing a specific number of points that need to be made and then try to
rattle off those points based purely on memory. This is because if you cannot
retrieve one of the points, it will look very bad and is if you do not know
what you are talking about. You lose the audience and they lose confidence in
you. It looked even worse for Perry because he has a history of poor debate
performances due to milder retrieval difficulties, characterized by brief but
long enough pauses that they indicate he is struggling with finding the correct
information he wants to say.
As alluded to earlier, retrieval of information is enhanced
when the person is very familiar with the topic area. This is because brain
cells form stronger and stronger connections with each other the more
well-known the information is. The technical name for this is having strong
synaptic connections. Synapses are the connections between nerve cells and
those bridges become strengthened when learning is enhanced, improving the
memory trace.
Clearly, Perry did not have detailed and specialized
knowledge of this particular topic. It is possible that he may have rehearsed
the information ahead of time, even many times, but sometimes pure rote
rehearsal is not enough, especially when there are so many other pieces of
information being rehearsed at the same time. We have all experienced this when
cramming for a test. Something similar is likely the case for Rick Perry who
made a last minute decision to run for the Presidency and thus had to try to
memorize answers in many different areas.
There are some ways around using rehearsal as a way to
improve memory efficiency and retrieval. One of the best methods is called
chunking, in which you reduce lengthy pieces of information to remember into
small, discrete units. An example is using an acronym. If Perry would have done
this, he could have saved himself a lot of grief. For example, he could have
used the acronym CEE (pronounced see) for which agencies he would like to “see”
eliminated. In this case, the acronym CEE is one unit of information but it
stands for three words: Commerce, Education, and Energy. These first letters
basically serve as prompts for the department names.
Another technique is to make the information emotionally
significant as this contextual significance improves the memory trace. Thus, if
he could think of one significant example of something severely wrong with each
of these three agencies (preferably personalized as much as possible) it would
improve his chances of remembering the three groups.
Sometimes, you can know the material well but anxiety can
interfere with performance. However, as a general rule of thumb, anxiety should
decrease the more familiar one is with the task at hand. In Perry’s case, there
likely was some anxiety due to his poor prior debate performances. He was
intimately aware of this as he has been widely criticized in the past, spoke
about it openly, and was publicly floating the idea of skipping the debates.
While anxiety can lead to a word recall problem, anxiety will then increase
further when the recall prolem occurs, which further interferes with coming up
with the correct word. It is like a road block exists and that road block needs
to be cleared before the frontal lobe (prefrontal cortex) can execute an
effective search and help the medial temporal lobe access the correct
information. The medial temporal lobe acts as a memory retrieval and storage
center.
If anxiety or some other emotion interferes with recall, it
is good to have a backup plan, such as notes. Being familiar with the notes is
key because you need to remember where to look very quickly if you plan to
recover form a brain freeze during a speech. Perry did not do this either
because despite exploring his nodes on the podium, he could not come up with
the correct word.
