I have a polygraph coming up and I wanted some advice. I was wondering if anyone could clarify the breathing contermeasures for me. It's a little confusing. :-*
I re-read chapters three and four of the Lielbehind the lie detector, so I kind of get the breathing measures a little more clearly now. I am more inclined to use the first breathing countermeasure, is this a good idea? Or do some of them work better than others. ???
FoxxyV,
If you have not done so you may want to review this thread: https://antipolygraph.org/forum/index.php?topic=2282.msg16155#msg16155 It should help clear up your questions.
Note that the information presented in the message thread linked in Brandon's post above has been incorporated in the 4th edition of The Lie Behind the Lie Detector (http://antipolygraph.org/lie-behind-the-lie-detector.pdf), which was released on 28 March 2005. The first breathing reaction discussed in this new edition, blocking (holding one's breath for a few seconds after exhaling), might be to some extent be considered the "best" not only in that it is the easiest, but also because (and this is something we chose not get into in the book) when there are two breathing reactions (one to a relevant and one to a "control" question that are being compared) that appear to be about the same in magnitude, it is now the Department of Defense Polygraph Institute's practice to "break the tie" by giving greater weight to the respiratory reaction with the shortest line length. Because blocking flattens the line, it produces the reactions with the shortest line length. However, if one is maintaining one's baseline breathing during the asking of the relevant questions, there should be no "ties" to be broken, and respiration line length should not become a factor in scoring. For countermeasure purposes, any one of the five breathing reactions listed should do nicely.
You guys are being soooo helpful in this. I am kind of nervous about taking the test, but you all are making me feel alot better. ;)
to clarify..
you should hold your breath on the controls questions after telling a lie in the controls....
"did you ever tell a lie"...answer "NO"....hold breath for 5 sec...then exhale....repeat till next questions...
Is this the correct procedure

No, you have it precisely wrong. If breath-holding is to be used as a countermeasure, one should
exhale and wait for a few seconds before inhaling. This is clearly explained (illustration included) in Chapter 4 of
The Lie Behind the Lie Detector (http://antipolygraph.org/lie-behind-the-lie-detector.pdf) (at p. 147 of the 4th edition).
Tell you what Foxy - go ahead and take the advice of these guys and when the examiner catches you, make the admission that you were deliberately manipulating your test. They'll just love you - and you'll be out of a job. ;D

Eastwood,
Why don't you just go troll somewhere else? Some people will be out of a job by TELLING THE TRUTH.
