11. Posttest Interview.
Upon completion of the actual testing phase of the
examination, the examiner studies the chart tracing and arrives at one of three
conclusions.
He may conclude the results to be "DECEPTION INDICATED," "NO
DECEPTION INDICATED," or "INCONCLUSIVE."
a. If a "NO DECEPTION" conclusion is made:
(1) The examinee is informed that the test has been completed and that the
preliminary review of the charts is similar to a doctor's reading of a wet X-ray
and that a final conclusion cannot be made until the charts have been subjected to
a detailed analysis.
The examinee is assured that evaluation of the charts will
take a few days and that the investigator assigned to the case will furnish him the
results.
It should be emphasized to the examinee that if he is not contacted he
may be assured that his responses to the specific test questions did not indicate
deception. He is informed, however, that the test covered only a specific area of
the investigation, and a later one may develop more information. At this time, he
should be dismissed from the room.
(2) Within 72 hours of the completion of the test, the examiner will
forward the polygraph charts along with a polygraph examination report (Figures 4-5
and 4-6) and all allied documents to the Crime Records Center, Polygraph Division,
USACIDC, for quality control review.
b. If a "DECEPTION" conclusion is made, the examiner conducts an interview
with the examinee.
He attempts to determine the causes of the specific
physiological response on the charts.
The questioning techniques used by the
examiner are similar to those used by any investigator. He selects his questioning
approach before the test begins based on the information from the investigator and
on the examinee's background.
During the test, he will modify or change his
approach according to the results of the test and the effect it seems to be having
on the person.
c. When a conclusion cannot be reached after the testing, including
continuation on later dates, the examiner interviews the examinee to determine the
cause of responses noted on the chart tracings.
If, after the interview, he is
still of the conclusion that further testing would not be productive, he will
render an "INCONCLUSIVE" report.
The examiner would then confer with the
investigator and the authorizing representative.
He will explain why he believes
there should be no further testing.
d. He may render a "NO OPINION" conclusion, when an examination has not been
completed. This may be necessitated should the examinee refuse to continue prior
to the running of charts, or before enough charts have been obtained upon which an
opinion of "DECEPTION INDICATED" or "NO DECEPTION INDICATED" may be based.
e. Upon
completion
of
the
test
and
posttest
interview,
the
investigator discusses the results with the examiner.
If during the test,
the
examinee made an oral admission, confession, or other type statement,
the
investigator should obtain a written one.
