I work with physiological signals where it's conventional to express the size of signals obtained in diffrent experimental conditions as ratios of signal size in a baseline condition. I routinely take log transforms of the ratios before analysis but scarcely anyone else does. Am I being too fussy?

Give an example of a "psychological signal." Is someone twisting a dial to indicate sensory strength? If the upper end of the signal can be very large, then you are doing the right thing.
