Rats were trained to lick for food reward on a water delivery tube. Odor stimuli which preceded an unavoidable shock produced complete suppression of the licking while the equivalent air stimulus without the odor present did not disrupt the licking. When the odor was removed from the olfactometer, the rats suppressed partially to the air stimuli delivered from the previously odorized olfactometer.
