i was wandering if someone could beat the poly by using the following two countermeasures, a sedative and biting tongue? i was thinking that a sedative would keep the responces to the relevant questions to a zero while biting tongue would increase the responces to the controll questions. would this work?

It might work, but I'm not aware of any research on this approach.

thanks george
would the sedatives really do anything? would they really keep the responces to the relevant questions down? are there any areas that the polygraph tests that the sedatives do not cover?

As I mentioned, I am not aware of any research on the effects of sedatives on CQT polygraphy. A study of the effects of anti-anxiety drugs on the GKT (Iacono, W.G., Cerri, A.M., Patrick, C.J., & Fleming, J.A. Use of antianxiety drugs as countermeasures in the detection of guilty knowledge. Journal of Applied Psychology, 1992 Feb;77(1):60-4) "showed that drug status had no influence on the outcome of the GKT."

It has been pointed out to me that a 1981 study showed that a tranquilizer decreased the accuracy of the GKT. See Waid, W.M., Orne, E.C., Cook, M.R., & Orne, M.T. Meprobamate reduces accuracy of physiological detection of deception. Science, 1981, 212, 71-73).
