Abstract
Physiological induction transferred from one eye to the other or binocular induction was studied by the method of electrostimulation with electrical phosphenes as an index.
1. The properties of curves of induction were the same for monocular and binocular inductions and correspond well to the properties of monocular and binocular contrasts.
2. There is, however, a striking difference between monocular and binocular induction in the rate of development. The latency of binocular induction was found to be about 300 msec., while that of monocular induction was about 40 msec.
3. It took about 4, 000 msec. for full development of binocular induction, but such a short period of about 100 msec. was sufficient for monocular induction to develop in full magnitude.
4. The correlation between physiological induction and psychological contrast was discussed.
