The Examination

Just what can I expect when I take…..

The Examination

Polygraph Instrument is merely a Psychophysiological recording device. A Polygraph Examination is technically referred to as a Pyschophysiological Detection of Deception Examination.

The type of Instrument used can be either Analog or Computerized.

The word Polygraph itself, means simply “many writings”. What we today refer to as a Polygraph or Lie Detector is actually a scientific instrument (not a machine) which is capable of simultaneously recording up to five channels of data. This data is the specific physiological changes produced by an individual when they are asked questions pertaining to a specific area under investigation. These recordings or graphs which are known as “polygrams” are then interpreted by a Certified Expert or Polygraphist.

Each individual afforded a polygraph examination is to be treated with……. understanding courtesy and most of all respect.

The examination consists of 3 phases.

~The normal sequence would be three charts and a familiarity test. More charts may be secured if necessary.

1 Pre-test Interview: discussed would be the actual issue that isThe Examination
under investigation along with the polygraph instruments operation and
laws governing polygraph usage. In addition, medical data and background
information is obtained. Release forms are then reviewed and completed, since
every polygraph examination is a voluntary process. Every question to be
asked is thoroughly reviewed.

2 The Testing Sequence: it would be at this point, that the actual
“testing takes place”. This is when the collection of data to be analyzed is
made. As well as the Familiarity Test to acquaint one with the Instrument.
That data being the physiological responses of the examinee. All questions
asked and the answers are permanently recorded. They are asked no less than
two times and on no less than two series of tests, usually three charts are
obtained. If necessary additional charts are collected.

3 The Post-test: it is at this juncture when the results of the examination
are reviewed and scored. Under most normal conditions, the examination
results are immediate following the Test and it’s review by the Polygraphist.
The test results are then discussed. It is at this time that the examinee has an
opportunity to explain any responses in question areas where there are
significant responses present.

~This entire process is the examination. Not just the collecting of the Polygrams.

The Polygraphist then scores the polygrams numerically. His determination of the responses to the relevant questions are the basis for his rendering an opinion as to whether or not, that individual has given answers which show significant response or show no significant response. These determinations can also be refereed to as ~ Deception Indicated (DI) ~ No Deception Indicated (NDI) or they are ~Inconclusive (INC) no opinion is being rendered.

We at Fred R. Meyer A.C.P. Forensic Polygraph, ONLY utilize the state of the art Axciton Computerized Polygraph Systems with three (3) scoring algorithms in addition to our own independent numerical evaluation of all data in accordance with American Polygraph Association Standards.

The entire process is likely to exceed two and one half hours or more, It can not be rushed. When necessary…..

a Re-Exam or Re-Test may be required on another day.
