| Abstract: | In three experiments, the specificity of action of occasion setters was examined, using a discretetrial leverpress procedure. Rats’ acquisition of anXA+, A?, XB?, B+ discrimination, in which a single feature cue (X) signaled the reinforcement of responding in the presence of one target cue (A) and the nonreinforcement of responding during another target (B), was no more difficult than acquisition ofXA+, A?, X?, B+ orX+, A?, XB?, B+ discriminations, in whichX signaled only one target-response-reinforcement contingency. In transfer tests,X did not modulate responding controlled by other cues that were untrained or consistently reinforced, either when the elements of the compounds were presented serially or when they were presented simultaneously in training and testing. However, after serial, but not after simultaneous, compound training ,X facilitated responding controlled by a cue that was trained and then extinguished. Implications for the nature of occasion setting and configurai learning are discussed. |
