TO EXPECT IN A POLYGRAPH EXAMINATION
polygraph examination has three phases that the test subject will
go through. The first stage is the pretest phase where
the polygraphist will obtain your written permission to take a polygraph
examination, determine your suitability to take a polygraph test
by going through a background form with you and the polygraph is
explained in detail to you. You and the polygraph examiner will
then talk about the circumstances surrounding the issue of why you
are taking a polygraph test.
The second stage is the in test phase where the examiner will prepare
the test questions and review them all with you prior to the actual
testing. You are then attached to the polygraph and only the reviewed
questions will be asked on your test. The attachments simultaneously
record physiological responses which can be analyzed by the examiner.
third phase is where the examiner will do an analysis of the polygrams
and from that will come to an opinion.
No one can be made to take a polygraph examination. All tests must be voluntary.
Polygraph components are placed across the chest, on your fingers
and a cardio (blood pressure) cuff is placed on the arm
time you are with the polygraph examiner is usually 2-3 hours
depending upon the issue.
It is natural to be nervous when taking a polygraph test and
the examiner realizes this. Nervousness does not normally interfere
with the test procedure
is never any surprise questions asked on a polygraph examination.
