The acquisition and transfer of stimulus control in discrete-trial operant feature positive and feature negative discriminations was examined in two experiments with rats. When the feature and target cues were presented simultaneously on compound training trials, the feature appeared to acquire simple excitatory or inhibitory control, which readily transferred to other target cues and which was substantially reduced by post-training counterconditioning. Conversely, when the feature preceded the target during training, the feature's control was relatively more specific to responding in the presence of its original target and less influenced counterconditioning. These results are comparable to outcomes of analogous experiments (previously reported) that used Pavlovian conditioning procedures.
