I recently took a pre-employment polygraph and was told that I had one issue with one of the questions:

My polygrapher said that I was "responding" to one of the questions, but kept asking me if there was something about the way it was phrased that would  make me respond.   

My question is -- is there a difference between the timing of a reaction and what it is supposed to indicate?  I got the impression from his statements and what he later told me that he didn't think I was lying about the answer, just that the way it was asked I "responded."  Is there a difference in terms of what that would look like on the charts, or did this guy just think I was honest Joe? Would there be a difference between getting weird reactions right after the question is read vs. during/after an answer?

I hope that question is clear enough...
