Abstract

The interaction of subliminal effects arising in the retina from two stimuli presented at adjustable time and distance apart from each other is studied (with the aid of measurements of frequencies of seeing) for each stimulus separately and for the combined flash. The chance for successful interaction as a function of time and distance between the stimuli is deduced quantitatively. Experiments refer to red and green flashes on red and green adapting fields, in peripheral and foveal vision. Except for integrate capacity in space in the fovea, a considerable decrease in these capacities is demonstrated for higher levels of adapting brightness. The amplitude of variation in sensitivity during adaptation is estimated.
