心理学家对遗忘曲线的形式争论了一个多世纪。我们重点解决了三个问题，这些问题阻碍了这个问题的明确答案。首先，我们分析了纵向实验的数据，测量了学习后1分钟至28天的线索回忆和干完成度，每个间隔每个参与者的观察结果比以前的研究更多。其次，我们使用分层模型分析数据，避免了由于平均参与者而造成的扭曲。第三，我们在贝叶斯框架中实现了这些模型，使我们的分析能够考虑候选遗忘函数相互模仿的能力。指数函数对显式和隐式检索指令下收集的个体参与者数据都提供了最好的拟合，但贝叶斯模型选择更倾向于幂函数。所有的分析都支持上述概率渐近保留，这表明，尽管学习时间很短，但一些记忆的存储实际上是永久的。(C) 2010爱思唯尔公司版权所有。
Psychologists have debated the form of the forgetting curve for over a century. We focus on resolving three problems that have blocked a clear answer on this issue. First, we analyzed data from a longitudinal experiment measuring cued recall and stem completion from 1 min to 28 days after study, with more observations per interval per participant than in previous studies. Second, we analyzed the data using hierarchical models, avoiding distortions due to averaging over participants. Third, we implemented the models in a Bayesian framework, enabling our analysis to account for the ability of candidate forgetting functions to imitate each other. An exponential function provided the best fit to individual participant data collected under both explicit and implicit retrieval instructions, but Bayesian model selection favored a power function. All analysis supported above chance asymptotic retention, suggesting that, despite quite brief study, storage of some memories was effectively permanent. (C) 2010 Elsevier Inc. All rights reserved.
