In 2 experiments using milk‐suckling from an anesthetized dam as the reinforcer, evidence is presented that the transitional age in rat pups for learning of persistence as a result of appetitive partial reinforcement is between 11 and 12 days of age. In Experiment I, pups 12–13 days of age showed the partial reinforcement extinction effect (PREE) whereas 10–11‐day olds did not. In Experiment II, pups trained at 11–12 days and tested at Day 13 did show a PREE at Day 13 but those trained at 10–11 days did not.
