Compared with the data of goldfish trained only with stimuli correlated with reinforcement, interspersed reinforcement‐stimulus and extinction‐stimulus trials resulted in sharper stimulus control and a marked reduction in the percentage of key‐presses emitted in the presence of stimuli located near the extinction stimulus on the test dimension. If non‐reinforced trials were not interspersed with reinforced trials, there was no sharpening of stimulus control and less reduction in key presses in the presence of stimuli near the extinction stimulus on the test dimension.
