Note that our nervous system isn't instantaneous. That could be a factor in the simultaneous-touch test that was done. I found this online, but couldn't find the original source: "The average reaction time for humans is 0.25 seconds to a visual stimulus, 0.17 for an audio stimulus, and 0.15 seconds for a touch stimulus." Our brain probably tries to compensate for this, but inaccurately?
