In four experiments we assessed the effect of systemic amphetamine on the ability of a stimulus paired with reward and a stimulus that was not paired with reward to support instrumental conditioning; i.e., we trained rats to press two levers, one followed by a stimulus that had been trained in a predictive relationship with a food outcome and the other by a stimulus unpaired with that reward. Here we show, in general accord with predictions from the dopamine re-selection hypothesis [Redgrave and Gurney (
