So if you take out the breathing what would you score it and why?

First, bear in mind that this is just a portion of a polygraph chart. Only a single relevant question is shown. Also, I suspect that a polygraph operator might adjust the amplitude of the electrodermal channel before hand scoring the charts.

Omitting the respiratory channel, I would score the one relevant question compared to the two "control" questions as "0" or inconclusive, because the reactions on the electrodermal and cardio channels appear to be about the same in magnitude.
