六个年龄组的大鼠进行训练，以运行一个小巷无论是部分（PRF）或连续强化（CRF）。训练在6个不同年龄开始的2天期间进行，并且在约12小时后开始消退。有一个明确的部分强化灭绝效应（PREE）在所有年龄段，特别是在PRF训练后，灭绝和年龄之间的反比关系。保留和持久性以及即时持久性进行了测试后，收购在3个不同的年龄。立即消光试验证实了上述结果。在延迟消退试验中，所有年龄组在保留和耐久性操作后，PRF后的消退阻力均大于CRF后。在这两个测试是有影响的年龄在原始收购的大小成人持久性。这些实验证实了早期的研究结果，即在断奶年龄接受训练和测试的大鼠中存在显著的持久性，表明这种持久性在断奶前甚至更大，并表明它保留到成年初期。
Six age groups of rats were trained to run an alley for either partial (PRF) or continuous reinforcement (CRF). Training was during a 2 day period starting at 6 different ages and extinction was initiated about 12 h later. There was a clear partial reinforcement extinction effect (PREE) at all ages and, particularly after PRF training, an inverse relationship between resistance to extinction and age. Retention and durability of persistence as well as immediate persistence were tested following acquisition at 3 different ages. The immediate extinction tests confirmed the above results. In the delayed extinction tests, greater resistance to extinction following PRF than following CRF was found in all age groups after both the retention and durability manipulations. In neither test was there an effect of age in original acquisition on the magnitude of adult persistence. These experiments confirm earlier findings of remarkable persistence in rats trained and tested at weanling age, show that the persistence is even greater in preweanlings, and show that it is retained into young adulthood.
