Learning based on reward prediction error (RPE) was originally proposed in the context of nondeclarative memory. We postulate that RPE may support declarative memory as well. Indeed, recent years have witnessed a number of independent empirical studies reporting effects of RPE on declarative memory. We provide a brief overview of these studies, identify emerging patterns, and discuss open issues such as the role of signed versus unsigned RPEs in declarative learning.

奖励预测错误和声明性记忆

基于奖励预测误差 (RPE) 的学习最初是在非陈述性记忆的背景下提出的。我们假设 RPE 也可能支持声明性记忆。事实上，近年来见证了许多独立的实证研究报告 RPE 对陈述性记忆的影响。我们简要概述了这些研究，确定了新出现的模式，并讨论了一些开放性问题，例如签名与未签名 RPE 在声明式学习中的作用。
