In discrimination learning, the negativity of the stimulus correlated with nonreinforcement (S–) declines after 100 training trials while the stimulus correlated with reinforcement (S+) is paradoxically more positive with lesser amounts of discrimination training. Training subjects on two simultaneous discrimination tasks revealed a within‐subjects overlearning reversal effect, where a more‐frequently presented discrimination problem was better learned in reversal than was a discrimination problem presented less frequently during training.
