一个有影响力的认知模型假定了两个基本的记忆过程：回忆，这是详细的，但相对缓慢，熟悉，这是快速的，但缺乏细节。在非人类中，这种双过程模型的大多数证据来自大鼠受试者工作特征（ROC）曲线的分析，但ROC分析是否可以证明双过程一直受到质疑。在这里，我们提出了独立的收敛证据的双进程模型从恒河猴的识别错误的分析。根据处理持续时间的不同，以三种不同的方式进行识别选择。短潜伏期错误是不成比例的假警报熟悉的诱惑，这表明熟悉的控制。中等潜伏期的反应不太可能是假警报，更准确，这表明一个回忆过程的开始，可以正确地拒绝熟悉的诱惑。长潜伏期反应是猜测。一个响应的最后期限增加了误报，这表明，限制处理时间削弱了回忆的贡献，加强了熟悉的贡献。总之，这些研究结果表明，快速熟悉和缓慢的回忆在猴子，猴子使用“选择拒绝”的策略，以取消虚假的熟悉，和灵长类动物的识别性能的特点是由一个双过程模型组成的回忆和熟悉。[本文提供补充材料。]
One influential model of recognition posits two underlying memory processes: recollection, which is detailed but relatively slow, and familiarity, which is quick but lacks detail. Most of the evidence for this dual-process model in nonhumans has come from analyses of receiver operating characteristic (ROC) curves in rats, but whether ROC analyses can demonstrate dual processes has been repeatedly challenged. Here, we present independent converging evidence for the dual-process model from analyses of recognition errors made by rhesus monkeys. Recognition choices were made in three different ways depending on processing duration. Short-latency errors were disproportionately false alarms to familiar lures, suggesting control by familiarity. Medium-latency responses were less likely to be false alarms and were more accurate, suggesting onset of a recollective process that could correctly reject familiar lures. Long-latency responses were guesses. A response deadline increased false alarms, suggesting that limiting processing time weakened the contribution of recollection and strengthened the contribution of familiarity. Together, these findings suggest fast familiarity and slow recollection in monkeys, that monkeys use a "recollect to reject" strategy to countermand false familiarity, and that primate recognition performance is well-characterized by a dual-process model consisting of recollection and familiarity.
