Studies manipulating emotional valence in prospective memory (PM) have so far revealed inconsistent results. In the present study, two experiments were conducted to systematically disentangle the effects of varying emotional valence in the encoding versus retrieval phase of PM in older adults. Results showed that, while cue valence at retrieval had no influence on PM performance, at encoding both positive and negative valence resulted in reduced PM performance. Findings suggest that emotional valence may have an influence on mnemonic processes at encoding rather than modifying cue detection in aging.
迄今为止，有关前瞻性记忆（PM）中情绪效价操控的研究得出了不一致的结果。在本研究中，我们进行了两项实验，以系统地厘清老年人在PM的编码阶段与提取阶段中不同情绪效价所产生的影响。结果显示，虽然提取时的线索效价对PM表现没有影响，但在编码时，正性和负性效价都会导致PM表现下降。研究结果表明，情绪效价可能在编码时对记忆过程产生影响，而非在衰老过程中改变线索检测。
