TL;DR
The duration of the "psychophysical time quantum" measured through the application of a two-state model of successiveness discrimination is equal in magnitude to the modal zero-crossing interval of the alpha rhythm.
Abstract
The duration of the "psychophysical time quantum" measured through the application of a two-state model of successiveness discrimination is equal in magnitude to the modal zero-crossing interval of the alpha rhythm. The two quantities have similar distributions and they are correlated over individuals.

Reaction times were found to be reliably faster when the stimulus light was flashed during certain portions of thealpha wave, thus supporting the hypothesis of an excitability cycle being related to the alpha wave.

131 Citations1963Walter W. Surwillo
The data support the hypothesis that the brain-wave cycle is the basic unit of time in terms of which a response is programmed by the central nervous system, and it was inferred that EEG frequency is thecentral nervous system factor behind age-associated slowing in response time.

It is concluded that the temporal process can be thought of as a succession of equally-spaced points in time occurring at a rate of approximately twenty points per second.
Electroencephalography and Clinical NeurophysiologyThe relation of decision time to brain wave frequency and to age
62 Citations1964Walter W. Surwillo
Strong evidence was obtained for the proposition that subjects with slow brain waves require more time to decide between two alternatives than subjects with fast brain waves, suggesting that EEG frequency is the factor behind the age-associated drop in information capacity of the central nervous system.

Experiments confirm the expected linear relation between the probability of discriminating pairs of successive from pairs of simultaneous signals and make it possible to infer the period of attention.
