I am looking for some documentation to back up what I learned about the BiZone. I'm looking for the research/standards that brought about these rules in the first place. Some of the questions apply to more than just this technique...a general principle is fine as well, I'd just like the paperwork to show where that principle was established. Thanks in advance.

1. The BiZone is Always a single issue test.

2. Both Relevant questions in the BiZone MUST be on the same aspect of the relevant issue. did you do it? did you do it huh?

3. In the BiZone, you cannot pass one relevant and fail the other.

4. In a polygraph report, you cannot try to explain away a deceptive response by saying the examinee was responding emotionally rather than physiologically. (this examinee is not a victim)

These are all things I've been taught, however, I need to be able to prove WHY they are true, other than Chuck told me so in school.

By the way, I'm okay if some of the principles are not based on research at this time, but are standards held and adhered to by APA, aapp, daca nonetheless.

thanks again.

DACA has a handout on the "You Phase" ("Bi-Zone" is an improper term for the format)that Donnie Dutton distributed at AAPP in Chicago and APA in Las Vegas. It includes most of what you are suggesting, including scoring and decision rules. I can send it to you if you wish by regular mail. To the best of my knowledge, there is no research to support this as of yet (Mark or Barry or Ray or Don K.could tell you if any has surfaced yet). I know there was some in the works.

Cleve Backster may have some, too, since he developed the "You Phase" in both a 3 spot and the (more well known) 2 spot; however, his question sequence is different than the DACA version since he asks the 1st symptomatic question before he asks the sacrifice RQ since he believes the SAC RQ should be as close to the 1st RQ as possible to have its full effect. Also, his scoring is different than the DACA scoring as well.

At APA somebody presented on the Backster YOU-phase, and its accuracy was just as we'd expect. It should be published soon. Don K had a part in it, so maybe he knows the numbers off the top of his head. There was one caveat in that the research wasn't truly a validation study, and it probably over estimates accuracy.

Elmer, the paper you speak of would be very helpful, however, I sort of need it yesterday. Is it in digital format anywhere so it could be emailed?

In regards to my questions, is what I've written there the same understanding that you have for that technique/those situations? Meaning other than the word BiZone being inaccurate, do the other points seem accurate to your current knowledge?

If, during the post-test interview, the subject gives you a plausible reason for his or her response (that you somehow failed to control for in the pre-test), you may not have any confidence in the result, in which case you couldn't call it one way or another.

They tell us in school to make sure our examinee understands questions to mean thing to both of us, but how many have learned in the post test that didn't happen? I recall one case (and it really wasn't mine - it pre-dated my polygraph days), that while the examiner was scoring his charts, the investigator "checked in" on the subject, and during their brief conversation, the subject asked the investigator what one of the words in the RQs meant. (English was his second language.)

In that instance, the reactions were probably due to "confusion," but who knows?

1. The BiZone is Always a single issue test.

Answer: Yes

2. Both Relevant questions in the BiZone MUST be on the same aspect of the relevant issue. did you do it? did you do it huh?

Answer: Yes

3. In the BiZone, you cannot pass one relevant and fail the other.

Answer: The old “deceptive to one, deceptive to all” phrase applies as traditionally conducted.

4. In a polygraph report, you cannot try to explain away a deceptive response by saying the examinee was responding emotionally rather than physiologically. (this examinee is not a victim)

Answer: You could explain why you decided to opine a test inconclusive (within one’s scope of experience, knowledge, and education), but it does not reverse the charts and make a deceptive opinion truthful.

Concerning whether to use the term Bi-ZCT, Bi-Zone, or You Phase, I’m not sure any of the terms are truly representative of what is done in all examinations.

A zone is an area of distinction. As we use it, there are two/bi areas of distinction for scoring purposes in a “Bi-zone” polygraph test. So, “Bi-Zone” simply refers two areas of distinction. “Bi-ZCT” is used to describe two distinct areas of comparison. This would be an acceptable term to describe the federal method of Bakster’s “You Phase”.

A “You Phase” is a Backster term. As I understand it, the phase poses questions of direct involvement. “Did you steal any of the money?” The “You Phase” proceeds a “SKY” test. So, as Backster uses the terminology, this too is representative of what is being done. The examiner is conducting multiple testing phases.

As a side note, I have heard that some deceptive subjects are subjected to the “All You All Phase” as the last stage of an examination.

I believe "All You All"

is correctly spelled

"All-Y'all"

In New Jersey regional dialect, the term "You's" is probably acceptable, but I would e unsure about the adoption of the term "You's-phase" as it seems imply testing multiple subjects at once.

Maybe in a larger department, in which multiple subjects could be tested simultaneiously by different examiners.
