Abstract
The so-called refractoriness of the N1-P2 wave of the vertex evoked potential is examined using an experimental procedure based on an analog clock that enables control over temporal uncertainty. It is shown that in both the visual and auditory modalities, variations in temporal uncertainty underlie refractoriness, although in the auditory modality, another variable, designated “firstness,” may also play a role. The potential value of the clock paradigm is also explored in time-locking emitted potentials in the missing-stimulus paradigm.
