This story is out of Kingsport Tenn....wonder if Dr. E. Baker Group was instructing this one as well.Chief is all about the DOD using the DVSA...Some comments on the story challenge the DOD usage comments though... Tony
http://www.timesnews.net/article.php?id=9012808 Wonder what the taxpayers in Bristol and Kingsport would think of this as well! [This message has been edited by Toneill (edited 03-31-2009).] IP: Logged |

I just read the article and was about to post it here, glad you beat me to it.I have a question. What exactly is the stance of DOD on this as of now? Because obviously in the 'current' sales pitch for this $1,500 equipment with only 60 hours of training, they are relying heavily on 'this is the same thing the DOD is using in the middle east to fight terrorists' to give it legitimacy it would probably not hold on its own. ------------------

DoD POLICY:A few years ago The Under Secretary of Defense for Intelligence (USDI) found out that CVSA was being used without prior authorization by some military units in the field. He immediately published a memorandum (later followed by a DoD directive) specifically forbiding the use of ANY Credibility Assessment (CA) device in DoD OTHER than polygraph, unless first specifically authorized by DoD. Right now the ONLY other technology authorized is PCASS. It took awhile to stop certain units who thought they were "special" from using the CVSA, but if any still are, they are doing so in direct violation of DoD directives and USDI policy. IP: Logged |

Thank you so much for the clear answer. Is this directive available for public viewing anywhere?In other words, if I wanted to convince someone of the current stance of the DOD, is there documentation I can access to back that up? ------------------

I think this may be what you are looking for. Let me know if this will work for what you need. DoD Directive 5210.48, “Polygraph and Credibility Assessment Program,” January 25,
2007 Section 4 PP 4.2 and DoD Directive 3115.09 DoD Intelligence Interrogations, Detainee Debriefings, and Tactical Questioning, October 9, 2008 Section 3 pp (d) § 6 These are the links http://www.dtic.mil/whs/directives/corres/pdf/521048p.pdf

Thought that this may be of interest to some folks.Hot off the press in Journal of Forensic Sciences (hat tip Mind Hacks), a study in which a Layered Voice Analysis system was tested independently and found to be effective at the chance level. In other words, you might as well flip a coin. Here’s the abstract: This study was designed to evaluate commonly used voice stress analyzers—in this case the layered voice analysis (LVA) system. The research protocol involved the use of a speech database containing materials recorded while highly controlled deception and stress levels were systematically varied. Subjects were 24 each males/females (age range 18–63 years) drawn from a diverse population. All held strong views about some issue; they were required to make intense contradictory statements while believing that they would be heard/seen by peers. The LVA system was then evaluated by means of a double blind study using two types of examiners: a pair of scientists trained and certified by the manufacturer in the proper use of the system and two highly experienced LVA instructors provided by this same firm. The results showed that the “true positive” (or hit) rates for all examiners averaged near chance (42–56%) for all conditions, types of materials (e.g., stress vs. unstressed, truth vs. deception), and examiners (scientists vs. manufacturers). Most importantly, the false positive rate was very high, ranging from 40% to 65%. Sensitivity statistics confirmed that the LVA system operated at about chance levels in the detection of truth, deception, and the presence of high and low vocal stress states. Reference: James D. Harnsberger, Harry Hollien, Camilo A. Martin, and Kevin A. Hollien (in press) Stress and Deception in Speech: Evaluating Layered Voice Analysis. Journal of Forensic Sciences

I just read the whole article. I was impressed with the lengths to which he went to remove environmental bias and his decision to use not only evaluators trained by the manufacturer, bet also representatives of the manufacturer,in an attempt to forstall claims that he was inherently biased against the technology as well as the criticisms the industry has leveled against previous studies.I can't wait to see Nemesysco's response to this one. ------------------

EB,I finally looked over the DOD documents you listed and even looked up the 'section 1564a of title 10' that was referenced in the document. Unless I just missed it, I can't find anywhere in these documents that state what exact instrumentation has been approved...you know something along the lines of at this time, only polygraph and PCASS are included. Without that one crucial part, it takes a bunch of jumping around documents to paint the right picture and so far, that picture is rather vague to me. ------------------
