Abstract
Subjects'' ability to discriminate the relative temporal location of pairs of events in a rapid sequential illumination of 4 lights positioned equidistant about a central fixation point was examined. There was no significant effect of cue delays up to 1 s indicating good retention of order information. The data were successfully analyzed in terms of a random walk model which provides separate estimates of discrimination and response bias indices. Evidence was provided for a unidimensional representation of psychological time for durations < 100 ms.
