In previous accounts both the moving object and flashing stimuli are unconditionally believed as something to be recognized. In this study, we conducted several experiments for FLE involved the problem of segregation between figure and ground. We found that interaction between moving objects and flashing stimuli as compatibility and complementarity of figure/ground effectively influences FLE. The results show us one aspect of the temporal perception, so that the subjective segregation between internal (as figure) and external (as ground) recognition would drive the time.

Our purpose is to set up a perception model that will enable us to simulate the behaviour of an agent in listening situation. It will lead to produce an "Intelligent" representation of a piece of music. We apply ourselves here to characterize intervention of Time in the musical perception in initiating a formal comparison between several models. Reasoning within a classical time logic supposes to take a priori time as a cause to describe the nature of knowledge. Our approach consists in supposing that the structure of knowledge a posteriori informs time; thus the nature of time is a consequence of the interpretation of events. This means we have to distinguish Universal Time from a bunch of musical times. We focus on some auditives illusions for their capacity to show particular properties of Musical Time.
