Abstract

The paper describes some experiments designed to test the predictions of an intermittency hypothesis concerning the influence of stimulus intensity on the delay in reaction to the second of a pair of visual stimuli. No agreement has been found between the experimental data and the predictions. A variant of the intermittency hypothesis is proposed in which the central system is not assumed to handle information on an all-or-none basis, but rather on the basis of a reduces sensitivity to new information; the sensitivity is assumed to be minimal immediately after the passage of a stimulus and is gradually restored to its initial value. Some psychophysical and neurophysiological evidence is given.
