Unconditioned Stimulus Functions of Drugs: Interpretations
This volume as a whole emphasizes that drugs and their effects can be conceptualized analytically as “stimuli” having three important stimulus functions—eliciting, reinforcing, and discriminative functions. In their eliciting function, drugs can act as unconditioned stimuli in a Pavlovian or Type-S conditioning paradigm; that is, drug effects, paired with other stimuli in the Pavlovian mode, can endow those stimuli with new behavior-eliciting powers. This is not quite the same as saying, however, that only the responses elicited by the drug have been conditioned to the new stimulus, as Pavlovian conditioned responses, or that the conditioned changes that have taken place must be interpreted as exclusively Pavlovian.
