Measuring Deviant Eye Tracking
David Thoreson Lykken, William G. Iacono, J. D. Lykken · Schizophrenia Bulletin · 1981
The two indices that have been proposed for quantifying the accuracy of smooth-following eye movements are shown to be interchangeable. This algebraic fact will permit comparability of values between laboratories only if workers who employ the signal-to-noise ratio (S/N) as their index measure S and N as the total signal and noise power, respectively, in the eye movement record.
