Its functioning is based on the emission of pulses of some sort by a pacemaker, and the number of pulses accumulated by the counter determines the perceived duration of a temporal interval. The pacemaker-counter device is frequently reported to include a switch component - often said to be under the control of attention [8] - that can interrupt the transmission of pulses to the counter. Many fundamental questions emerge from this clock concept. One relates to the pacemaker's pulse emission properties, which, depending on the models adopted, are considered to be deterministic or stochastic.

Such a quantal approach might begin with a basic psychological moment [34; see also 35], or the subjective now (see Binder or Atmanspacher and Filk, this volume), within which it is impossible to distinguish between two separate sensory events.
