Polygraph test sequence?

1. The polygraph examiner first confers with the client or investigators reads any reports

in connection with the incident and then plans the polygraph test.


2. Pre-Test Interview:


2.1 Advise the examinee of his / her rights, both legal & polygraph rights.

2.2 Discuss the case facts with the examinee.

2.3 Assess examinee’s ability to take the polygraph test (mental & medical history)

2.4 The examinee signs the consent form as well as all other relevant forms used during the

polygraph test.

2.5 Conduct a forensic assessment interview.

2.6 Generate and review all test questions in order to prevent extraneous reactions:


This will:


a)  Prevent novelty.

b)  Prevent cognitive activity.

c)  Remove ambiguities from relevant questions.

d)  Focus psychological set.


After  being  informed  of  the  purpose  of  the  examination,  the  examinee willingly

consented to polygraph testing and audiovisual recording of  the examination after he

or  she  was informed  of  and said that  he  or she understood the  testing  process.   The

examinee responded  to  questions  concerning  her  suitability  for  testing  and  in  the

opinion of the examiner, the examinee was suitable for testing.


3. An acquaintance test can be conducted to familiarize the examinee with the testing

process.


3.1.  The acquaintance test will proof to the examinee that the polygraph instrument is able

to detect a lie, when instructed to tell a lie. The innocent examinee now believes that

the  polygraph  instrument  will  proof  his  or  her  innocence.  The  guilty  examinee  now

knows that there is no way that he or she can lie during the polygraph test.

3.2.  The acquaintance test also allows the examinee to  get use to the specific instruments

that has been attached to his or her body.



4. In-Test Phase:  Record physiological data, a minimum of three (3) charts.



5. Chart  Interpretation:   The  examinee’s  level  of  nervousness  or  reactivity  is  not

explicitly  compared  against  other  people,  but  only  against  him or  herself;  he or  she

serves  as  their own  control.  The  examiner  evaluates  the  examinee’s  physiological

changes and renders an opinion of Truth or Deception.

All of our polygraphists were used (with overwhelming success) by different institutions for giving evidence in disciplinary hearings and CCMA cases.  However one of the most important facts in the evidence given by the polygraphist is the experience of such a polygraphist and the years he/she is a polygraphist.
