In any system we may talk about Y as the largest barrier between input and output if the following holds: (1) there are signals from the input which reach Y but do not go beyond Y; (2) any signal which does go beyond Y reaches the output. Of course, it should be recognized that the location of the largest barrier may be itself a stochastic variable for fixed conditions of stimulation, or vary as a function of conditions of stimulation. With regard to the latter possibility see reference 7.

Statistical time lag of the glow modulator tube was reduced to negligible values (i.e., less than 2 µsec) by continuously irradiating its cathode with ultraviolet radiation derived from a General Electric argon glow lamp AR-3 (U, Fig. 2; see also Fig. 1) whose output was filtered by Corning filter 5860 (T, Fig. 2) so as to pass only wavelengths below 390 mµ. A Kodak No. 4 filter (D, Fig. 2) plus the high-flint component of achromatic lenses B and G prevented the ultraviolet from reaching the subject's eye.

We have called this effect "Binocular Flash Diplopia." A detailed study of the phenomenon will be reported elsewhere.
For subject 1, this resulted in an intertrial interval which could range from 20 to 40 sec; for subject 2 the intertrial interval could range from 10 to 30 sec. The actual range for all responses, however, was 25 to 35 sec for subject 1 and 15 to 25 sec for subject 2.
Values of X2 were computed for each experiment with P′(B) as the theoretical value and P(B) at the different values of ITI as the observed values. Tley were sigificant in each experiment beyond the .0001 level of confidence. Since P′(B) is an efficient estimate of its population value and since sufficiently large numbers of measurements were taken the use of P′(B) as a population estimate is reasonable: cf., G. U. Yule and M. G. Kendall, Theory of Statistics (Charles Griffin and Company, London, 1940), p. 428.
