Abstract: Time perception is a term that encompass a broad range of phenomena, including simultaneity, temporal order, the perception of duration and interval. The role of attention is central to a basic account of the relationship between the actual timing of stimulus events and the perceived timing of those events: the more attention was paid, the longer the duration would be; and an attended stimulus was perceived to be earlier. The corresponding attentional theories comprised AGM, the integrated theory, and AUM. More exploration in neurobiology can push forward the study about the brain mechanisms of timing and the integration of cross-modal information.

Key words: attention, time perception, duration estimation, the perception of temporal-order
