Abstract:
This Viewpoint emphasizes interoceptive discriminative stimulus modulation of voluntary operant behavior (a la B. F. Skinner), rather than elicitation of Pavlovian conditioned reflexes. In doing so, I will restate how the operant drug discrimination paradigm may not only elucidate smoking and other addictive behaviors but also anxiety (Troisi, J. R., II. (2003) Spontaneous recovery during, but not following, extinction of the discriminative stimulus effects of nicotine in rats: Reinstatement of stimulus control. Psychol. Rec. 53, 579-592).
