Different successive hurdles tests.

[RealEyes]

While reading, I found a type of test that I can't find in TLBTLD. It sounds like a variation of the Relevant/Irrelevant test, but it's always referred to as the "successive hurdles" technique.

What is it?

What is the difference between a single-issue and multiple-issue test?

How would countermeasures be applied in this test?

RealEyes, "succesive hurdles" does not refer to a type of polygraph exam. It refers to "breaking out" suspected issues from a multiple issue exam and dealing with them in a single issue format. Any thread of accuracy polygraphy claims, is based upon testing of a single issue--as in "did you do this?" Not, "did you did this, that and the other?"
