Do they? Is it probabilistic?
Are they trained to press the bar?
Can we count anything outside of the bar press and record if they stand on their hind legs (rat) and if they scratch their ear?..
Pigeons are preferred in multiple response matching studies because they can readily be trained to peck different colored keys to get food and the keys can be back illuminated with stimuli, like colors, that rats don't discriminate.
Now you reinforce the bird by pecking on the red key, whatever its location, on a VI 20 sec schedule, whereby it gets a bit of grain on the average of every 20 seconds if it pecks there. On a green key, the grain is delivered on a VI 80 sec schedule. After a while, this dumb bird whose brain would fit comfortably inside your thumb matches to maximize reinforcement. She chooses to distribute 20% of her behavior to the VI80 schedule and 80% to the other. .
Of her own free will.
