Title: medical reasons
Post by: confused3 on Feb 19, 2005, 01:24 AM
My question is are there any medical reason a person can't take the CSVA. I know that epileptics can't take a polygragh test. I was wonder whether or not if it's the same qualifications for the CSVA.

Not sure, but I would be carefull, as If you use a medical reason it could be held against you as either not wanting to take the CSVA or the fact that if you medically cannot take it you may not be able to perform the job on other functions....

Well i have just learned that the CSVA is based on the autonomic nervous system when the csva reads a deception that means the nervous system has kicked in under stress.  In a person with a nervous disorder that could read a false positive or negative the test itself wouldn't be accurate.

This is what the makers of the device claim. When you look for any proof or research supporting this contention, you come up empty handed pretty quickly.

Is there any reason to believe that this test is accurate in persons free of disorders? Note that CVSA has not been shown to determine truth from deception more accurately than a coin flip in any study not financed by the manufacturer of the device.

I don't believe so but this test is based on the autonomic nervous system from my understanding. I was wondering if the CSVA has the same physical qualifications as the polygraph. A person with a nerological disorder can't take a polygraph because the reading wouldn't be accurate. (not that they are anyways)

I agree that this is what the maker of the device tells people. Still, I know of no peer-reviewed studies linking the voice, deception and the autonomic nervous system.

Until some are completed that show accuracy better than a coin flip, I wouldn't be confident that this "test" has anything to do with the autonomic nervous system.

In response to your original question, I know of no documented conditions for which CVSA examiners will refuse to test a person.

Like with polygraphs, the important thing here is that before we start discussing whether or not a particular technology can or cannot detect deception in people with medical conditions, it must first be shown to detect deception reliably in those with no known health issues.

With polygraphy and especially CVSA, this is not the case.
