[net.cog-eng] Sublimal messages -- info wanted

     I have written a program that flashes messages on my screen 
periodically -- I am being my own guinea pig in a behavior 
modification experiment.  I'm wondering how to maximize the subliminal
effect I will get.  Specifically ... 

     Should I be able to perceive the messages consciously?  Currently 
I transmit 250 nulls at 9600 baud (equals .29 second) and then erase 
the message.  If I happen to be looking at the right part of the 
screen, I can read the message.  If not, I am aware that something 
flashed there, but usually don't know what.  Should the message last 
longer or shorter?

     Currently I distribute the inter-message time normally around 3
minutes, with the standard deviation of 45 seconds.  Should I up the 
frequency?

     Has anybody else tried this?  With what results?
