Ok, Ken. I'll make a one more change. When red and green are both 
illuminated, a peck to one of them causes the other to extinguish and the 
one pecked begins flashing. It probably isn't necessary - I myself don't do 
this kind of experiment - but I'll go with that. The whole procedure, then, 

Start trial:

                                    Both keys white

     Peck left:                                              Peck right :

   Right key out                                          Left key out

Left key stays on                                    Right key stays on

      T seconds                                             T seconds

          Green:                                         Red 

        G flashes                             G out red flashes   R out 
green flashes

             4.0 s                                           1.0 s

     8.0 s inter-trial interval         20.0 s inter-trial interval      8.0

         BACK TO START----------------------------------BACK TO START

In addition, periodically, there are forced trials where the animal has to 
sample the contingencies programmed for one choice.

If the above doesn't show up formatted correctly, I'll repost it as a 
straight description.
