Do you speak as scientist who did an experiment with an EEG to find out if a flash of less than one second does affect the brain ?
Or are you talking out of a part of your anatomy more renowned for its venting power than for its thinking power ?
Let me further educate you, rascal :
Rensink, O'Regan, & Clark [1997] used what they called the "flicker" technique, in which, instead of an eye movement, a brief flicker was introduced between successive images. A first picture (picture A) would be shown for, say, 250 ms, followed by a modified picture (picture B). Inbetween A and B, a brief blank screen (bl) would be shown. This would cause a flicker, lasting about 80 ms, that is, a duration similar to that of an eye movement. The cycle A-bl-B-bl-... was then repeated. Observers were told that something was changing in the picture every time the flicker occurred, and they were asked to search for it.
Under conditions where no flicker was inserted inbetween the pictures (A-B-A-B-…) the change was immediately visible and totally obvious.
