It is not clear which type of mental countermeasures might work best (mental arithmetic vs. thinking frightening, unpleasant, or exciting thoughts) for any particular individual.

One cannot be absolutely certain that augmented responses to "control" questions will be stronger than any reactions to relevant questions. One thing you need to be clear on is that there is no "Pinnochio response" that people produce when lying. One may or may not produce significant physiological reactions measurable by the polygraph when lying.

Thanks for the input.  What type of mental measures work best?  

If you just alter your breathing and use a controlled anal-pucker will it produce a reaction higher than a relavent question reaction even if you are lying?

Note that in The Lie Behind the Lie Detector, we suggest a duration of 5-20 seconds for breathing reactions (not 20-30 seconds).

There is no sure way of knowing for sure how strong an anal pucker might be too strong. We suggest that submaximal effort be applied.

You might consider mental countermeasures as an alternative if you are concerned that an anal pucker might produce too strong a reaction.

Ive read TLBTLD and I understand the countermeasures but the one thing Im not sure of is how not to over-do it.  How do you know how much to do?

Do you just change your breathing for 20-30sec along with the anal-pucker and that will do it?  What is too much? ???
