When meditators avoid counting during time production things get interesting

Time production (TP) with or without chronometric counting both instantiates and reflects the working of an internal clock, as originally posited by Treisman. We exploit the fact that a number of experienced meditators, who had previously participated in a study wherein TP was assessed, and who had employed chronometric counting then, would be coming back to the lab to participate in a second study. We specifically requested that they should not employ chronometric counting this time, thus allowing us to contrast TP with and without counting. We report a qualitative difference between TP implemented by counting and TP without counting: The first is a linear function of target duration (T), while the second is not, and entails a discontinuity in the function. Requesting meditators not to engage in chronometric counting, and thereby forcing them to rely instead on other cues (sensory, bodily, etc.), might well be an appropriate context in which to observe such a discontinuity in TP.
