This test is now confirmed as a Doug Williams countermeasure case.DW's book was subsequently recovered from his residence, and he admitted to me to trying an "experiment," which he described as attempting several different CM strategies during the test. He also admitted to purchasing the book, reading it 4 times, and speaking with DW several times. He said Doug wouldn't really talk to him, but tried to answer his question quickly and then hand up. His question for DW seems to me to be some version of "why am I failing the polygraph while I'm telling the truth."

Way to go, Ray!Do you have any explanation or hypotheses about the downward spikes on the electrodermal channel? Gordon IP: Logged |

Gordon:The examinee would not give me detailed information on what CM strategies he tried, but he made a clear admission that he tried several things. He also made clear admissions about buying the book, reading it four times, and talking to DW several times. I can produce similar downward EDA activity by pressing or even subtly moving my fingers, changing the contact with the sensors. That's my best guess. I don't really know what he did. At the time of the test, I saw the problems, and called the test INC. He's had about 12 previous polygraphs. This is a maintenance test. He denies the instant offense, and will most likely be revocated from probation and resentenced to prison - for the duration of his lifetime. He would like to make the problem into an unfair-polygraph problem - as if its the polygraph results that say he can't be in treatment in the community. He simply doesn't want to take responsibility and doesn't believe he needs treatment. It's really more like a guy with cavities, who say's "no thanks" to his dentist. OK, he'll then be dealing with the problems all on his own. The court will have to decide whether or not it is comfortable with him living in the community while not in treatment. I think he would prefer to engage an argument about his polygraph results as a basis for decision (treatment and court), instead of an argument about his offenses and need for treatment/containment as a basis for decision. Here is a graphic of the OSS-3 report, with the Test of Proportions showing a significant result - meaning the pattern of activities does not appear to be random.

are you using Ag/AgCl Adhesive pads on this test?The electrodermal downspike looks like a temporary separation of the electrodermal sensor from the contact point. If he is tensing his hand or arm, to cause this, moving the plates or pads to the same side as the cardio cuff will show his movement on the cardio channel. ------------------

I have the sticky-gel pads but don't often use them. Cleanest sensors I've found, and my favorite, are the nickel-plated brass ones from Axciton. They work better for me than the the adhesive or the stainless. They don't magnetize or polarize, and they generally give less noise than all the other pads I have. Plating on mine is all worn off. Another nice thing about the Axciton finger plates is the velcro is riveted on, and has never come off. I hear Limestone will have some brass plates in the future. r ------------------

I've found that with wet electrodes (as Ray has said), pushing down gets the opposite effect you'd get with the plates: you get a downward spike - the opposite of what our CM encouragers predict! Isn't that just a shame?IP: Logged |

This examinee has recently admitted to having a towel in his shorts - per Doug Williams' advice. Seems to me someone would have a butt the size of a VW with a towel in the shorts. I think it's possible it was something other than a towel.r ------------------

Here is a funny.....The other day I tested a man who had some minor (admitted) violations and he attempted to use CM's during the poly. When confronted he said he didn't know much about polys but his wife had printed out a page. I met with the PO and the man was put in custody. His trailer (home) was searched and they found the full 'how to beat a poly' manual along with porn. The judge didn't like that and his probation was revoked and he was sent to prison.
