AN EXPERIMENT WAS CARRIED OUT USING THE STAATS AND STAATS PROCEDURE FOR CONDITIONING ATTITUDES TOWARD NONSENSE SYLLABLES. IN AGREEMENT WITH THE RESULTS OF COHEN, IT WAS FOUND THAT AWARENESS WAS CORRELATED WITH CONDITIONING AND FURTHERMORE THAT AN INTERFERING INTERTRIAL ACTIVITY, COLOR NAMING, SIGNIFICANTLY REDUCED BOTH AWARENESS AND CONDITIONING. SS WHO WERE UNAWARE OF THE DEMAND CHARACTERISTICS OF THE EXPERIMENTAL SITUATION, HOWEVER, DID SHOW A SIGNIFICANT CONDITIONING EFFECT. IN VIEW OF THE FURTHER FINDING THAT EXTINCTION DID NOT OCCUR EITHER WITH OR WITHOUT PARTIAL REINFORCEMENT, THE CONDITIONING EFFECT WAS INTERPRETED AS BEING A CHANGE, NOT IN AFFECT, BUT IN SYMBOLIC REFERENCE TO AFFECT.
