Abstract
Thirsty rats were exposed to a conditioned suppression procedure in which a drug, LSD, was the US and a 6,000-Hz tone was the CS. All animals demonstrated conditioning in that responding to obtain water on a VI schedule was suppressed during CS presentation. It was then demonstrated that stimulus generalization occurred when tones between 2,000 and 10,000 Hz were presented during subsequent extinction.
