We combined a feedback-based learning task with a recognition memory paradigm to investigate how reward-based learning affects the event-related potential (ERP) correlates of recognition memory in younger and older adults. We found that positive, but not negative learning improves memory and results in an increased early ERP old-new effect, which is typically associated with familiarity-based memory. This indicates that reward-based learning supports a fast and relatively automatic memory retrieval process. Furthermore, we found age-related impairments in reward-based learning, whereas memory for the learned information was intact in the elderly, suggesting that declarative memory might be less affected by aging.
我们将基于反馈的学习任务与识别记忆范式相结合，以研究基于奖励的学习如何影响年轻和年长成年人的识别记忆的事件相关电位（ERP）相关物。我们发现，积极的，而不是消极的学习可以改善记忆，并导致与熟悉度记忆相关的早期 ERP 新旧效应增加。这表明基于奖励的学习支持快速且相对自动的记忆检索过程。此外，我们发现基于奖励的学习存在与年龄相关的障碍，而老年人对所学信息的记忆完好无损，这表明陈述性记忆可能较少受到衰老的影响。
