Just what can I expect when I take.....




  • Polygraph Instrument is merely a Psychophysiological recording device .   
  • A Polygraph Examination is is technically referred to as  a Psychological 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.                                                                                   

·         Pre-test Interview:  discussed  would  be the   actual  issue  that is  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.

·         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. 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.

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

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.
