Figure 1. A model of time-sharing controlled by the discriminability (salience) of events.

Figure 1

A: The time-sharing model assumes limited attentional or working memory resources: time processing (left) and other processes (right) share the access to these resources. In particular, working memory for time is updated by two concurrent processes: time accumulation and active decay due to sharing of resources. The rate of memory decay is assumed to depend on the discriminability (salience) of the interrupting event. B: The interplay between time accumulation and working memory decay may result in a continuum of responses based on the discriminability of the distracter, from no delay (run response), to an apparent stop of timing (balanced time accumulation and memory decay), or a restart of timing after the distracter (reset response) (adapted from Buhusi & Meck, 2006a).
