Quote:that said the problem with fidelity tests are hiding things you consider unimportant.. at they might be but the concealing will cause you to react to the relevant questions..during question review, if you have any reservations about the questions they need to be changed.. if your concerns are not addressed you will probably "fail" the examination
Then again, one may very well "react", without lying, or hiding anything! As for "changing the question", it will still be a permutation of the original question, and his unconscious mind could register it as such. So if the polygraph interrogator claims, and the person believes, that something is bothering them about the original question, he might still end up reacting to the new question, as changed. It will still probably be along the same "line of questioning"!
Truth is, there can be many reasons behind a reaction as measured by the machine. According to the National Academy of Sciences:
Almost a century of research in scientific psychology and physiology provides little basis for the expectation that a polygraph test could have extremely high accuracy. The physiological responses measured by the polygraph are not uniquely related to deception. That is, the responses measured by the polygraph do not all reflect a single underlying process: a variety of psychological and physiological processes, including some that can be consciously controlled, can affect polygraph measures and test results. Moreover, most polygraph testing procedures allow for uncontrolled variation in test administration (e.g., creation of the emotional climate, selecting questions) that can be expected to result in variations in accuracy and that limit the level of accuracy that can be consistently achieved.

It is a common polygraph examiner ploy to claim that the machine is indicating that something "must be bothering you", or that "you must be hiding something!", and so you must disclose anything that it possibly could be no matter how "unimportant" it might be. This an effort to get information out of you they might be able to use against you later, or at the very least to justify the "reaction". IOW, so they can later say: "Well, you may or may not be lying about having an affair, but there was definitely something bothering you! You admitted such and such...etc." Bullshit! Don't fall for it if you take the test! Realize they are just "fishing". Just reiterate that your are telling the truth and nothing is bother you about YOUR ANSWER.
Seriously, read the "Lie behind the lie detector"
http://www.antipolygraph.org/lie-behind-the-lie-detector.pdf It explains this and much more about the polygraph. Read chapters 3 and 4 in particular. You might even share this with your girl friend.
Good Luck!
