OK, straight description.



At the start of the trial, both keys are illuminated white.





Peck left - right key out - t sec delay - green key - peck green - green 
flashes - 4.0 s delay - 12.0 s access to food - 8.0 s inter-trial interval - 
back to start





Peck right - left key out - t sec delay - red key and green key illuminated:





If red - green key out, red flashes - 1.0 s delay - 3.0 s access to food - 
20.0 s inter-trial interval - back to start.





If Green - red key out, green flashes - 4.0 s delay - 12.0 s access to 
food - 8.0 s inter-trial interval - back to start.



Which keys does the animal peck? What happens, if anything, as a function of 
changes in t?
