OPERANT EXTINCTION NEAR ZERO.
Extinction in the presence of each of two stimuli reduces the rate of pecking in the presence of each of them to zero or near zero. When, however, pecking a third stimulus is reinforced, responding is resumed under the other stimuli, and more responses are made to the stimulus least associated with extinction.
