- Nov 02, 2004, 03:03 AMI agree with what Jm said about the examiner's need to be able to comprehend and read the data correctly. Unfortunately, people can become certified to become CVSA examiners with relatively short and limited courses, which were designed by humans and therefore also limited. This in my opinion, is the largest problem with the technology...it merely detects stress in the voice, not a lie. It is up to interrogators to ultimately decide what may be a lie. This involves a great degree of technological and psychological know-how. If every cross-examiner knew at least how to read the data correctly, there may be more educated assumptions to who is actually lying, and who is merely nervous

- May 11, 2004, 03:26 AMI too stutter. I also just failed a CVSA a few months ago even though I was honest on every question. I wonder if that had anything to do with my failing?

You write:
I am afraid a dangerous play toy is a more apt description. Your assessment of "can lead to problems" is such a minimization as to be repugnant to all victims who visit this site. Such a description is analogous to saying that a child playing in the middle of a busy intersection can lead to problems. Get with it friend...this (polygraph screening) is behavior that is foolish, dangerous, and that most assuredly needs to be discontinued.
You further write:
Perhaps you might like to quote the leading detractors you refer to. I doubt any would indicate that the responses recorded via a polygraph are limited to either deception or STRESS . These are but two of a great number of things which may play a role in autonomic nervous system (ANS)-mediated physiological response.

- Sep 09, 2002, 04:42 PMAs a criminal investigator, and CVSA examiner, I consider myself open to various investigative tools: Polygraph.CVSA, micro facial expressions, eye movement ,ad nauseum. To flatly dismiss the Poly or CVSA is shortsighted. I have used all during interviews and have had obtained confessions. I have never had someone confess who was later found to be innocent. I don't know, but I am reasonably sure I have not got every single guilty party I have interviewed to confess. Nobody is that good. Make sure everyone understands that the Poly or the CVSA does not know deception from shinenola. They merely record stress. The most renowned and qualified detractors will concede that point. It is what the hell this jumble of lines and squiggles mean that causes the problem. The examiner must be able to minimize situational stress and key the issue questions in such a fashion as to maximize an accurate response. It is JUST a TOOL. I do agree with the forum that using these devices for pre-employment can lead to problems. Again I believe the integrity of the examiner will see the honest applicant safely through the ordeal.

- Aug 05, 2002, 10:42 AM1st. I stutter, I was wondering if my stuttering would affect my CVSA results.
2nd. I also have several "vocal tricks" I use to keep from stuttering. Even though my voice may sound normal to the human ear. I am afraid the CVSA may pick them up as lying.
Any info would be helpfull.
