A model for the fixed activation time scheduling of events is presented. Activation time is defines as the time needed for an event to regain dominance in the stream of events measured from the point in time at which it lost dominance. The fixed activation time scheduling rule states that some event must be ongoing at all times, that an ongoing event will continue until interrupted by another event, that every event has a predetermined activation time and that fulfilling the activation time requirement is the necessary and sufficient condition for an event to interrupt an ongoing event. The last condition sets this rule apart from those employed in quequeing theory since it does not allow events to be completed or queues to form. Derivations from the model concerning the dynamic organization of the stream of events, written in terms of the frequency and duration of events and the transitions between pairs of events, are given. Special attention is paid to issues that arise in deciding on the coding of events. It is suggested that the fixed activation time scheduling rule will apply to a wide variety of settings, environmental and behavioral, and this is illustrated by a detailed application of the model to observations on the stream of free behavior.
