“This aberration in the fabric of perceived time has been hotly argued as representing everything from evidence for noncausality to intention preceding awareness. But the explanation needn't be deeply philosophical. This coordination of inputs is an everyday occurrence. If you bump into a door, the sensory inputs from your nose reach the brain sooner than those from your big toe, yet you perceive hitting the door with your entire body all at once. The brain adjusts for these time lags. When I tap my foot, the motor movements are felt to be synchronous with my foot striking the ground. The length of time that it takes the sensation of my foot hitting the ground to reach the brain and be processed is not apparent. Without such adjustments, the varying delay between sensory inputs would create a kaleidoscopic sense of time, a present that is spread out over time ( a "thick" present) , as opposed to an instantaneous "now."”
