Polygraph samples

[matrix8]

Greetings,
     I am an Electrical Engineer and am looking for "Polygraph samples". This would include the paper "strip charts" or the newer electronic "trend charts" (copy of software reading?). I am looking for the analysis reports that would normally accompany the charts. In other words: This type of trend line is a supposed "lie", and this type of  trend line is supposed truth. It seems to me that this information would be available someplace. Maybe an anonymous donor, or contacting polygraph manufactures directly for sample readings? Thanks in advance!

If you ask real polygraph examiners for this they will laugh at you.  I don't know if this true, but they say  you won't be able to understand the lines because you need like a billion hours of training blah blah blah.  Go to polygraphplace.com and ask this same question and I bet they answer you this way.  It also might help you to understand what Relevant, Control, and Irrelevant questions are when looking at the responses on the charts.  Try reading the free book on this site, "The Lie Behind the Lie Detector" some knowledge on the subject.

I don't know where you might find complete polygrams (polygraph charts), but for illustrations of physiological reactions extracted from real charts, see Reid, John E. and Fred E. Inbau. Truth and Deception: The Polygraph ("Lie-Detector") Technique. Baltimore: Williams & Wilkins Co., 1966.

For rather crude illustrations of patterns which, according to Department of Defense Polygraph Institute (DoDPI) doctrine, reflect significant physiological responses, see the DoDPI document, "Test Data Analysis," which you can download as a PDF file or browse in HTML format at:

Matrix8, it would be helpful to know what you wish to do with the data, and what your situation is.  If you're thinking of developing new ways of analyzing the data, you may wish to submit a grant proposal to the DoD Polygraph Institute or other funding institutions.  If you're working on a Government grant, you are likely to get help from the polygraph community.

If you are at a university, you may be able to get appropriate data from a psychophysiologist in the Psychology Department or the Dept. of Bioengineering.

There is no such thing as a "lie reaction" -- a reaction which occurs every time a person lies and never under any other circumstances.  Nor a "truth reaction."  The reactions are generic short term physiological arousals, caused by any of a large number of stimuli such as being asked a question.  As George Maschke has often pointed out in other threads, the key issue is not so much what the reactions look like, but which questions they are occuring at.  The decision as to whether a person is telling the truth or not is an inference predicated upon a carefully constructed test protocol and appropriate testing conditions designed to eliminate or control competing sources of arousal.

Thus, generic physiological data showing short term arousal patterns may be adequate for your purposes, depending upon what your goal is.  If you provide additional details, I may be able to provide additional suggestions.

  Hello...I am also interested in finding "polygraph samples"  My son is doing a school project and this would be very benificial to his project if he had samples and such ...please help...I have searched everything possible..

If I ask my polygrapher for them, is he supposed to give them to me?
