Yes. This has been dubbed "presentiment" and has been found in quite a 
few studies where autonomic responses are recorded (including a few 
databases compiled independently for different purposes, and reexamined 
in light of this effect).

The advance responses tend to be associated with strong emotionally 
charged events (feelthy pictures, blasts of noise, pix of shocking 
wounds or accidents) but not with bland neutral stimuli. This is 
consistent with an affordance selected by evolution. It doesn't happen 
every time, and the signal has to be factored out from the background 
noise and jitter. But it's repeatable, and has been repeated 
sufficiently often now in different labs to make it pretty clear that 
this is a real phenomenon.
