老年人处理情感信息的方式与年轻人不同，他们更注重愉快的信息。情绪处理中与年龄相关的变化对记忆最好的信息类型有下游影响；年轻人对负面信息的记忆能力很强，而老年人往往对积极信息表现出更大的助记力。尽管这些认知变化以前已经讨论过了(Mather，2006；Mather Carstensen，2005)，但在这里我们回顾了可能调节这些与年龄相关的变化的神经变化。我们认为，老年人在情绪加工过程中前额叶区域招募的变化可能不仅反映了情绪调节的年龄相关变化，也反映了自我参照加工的变化。由于很少有研究检查支持老年人情绪和认知功能的神经网络之间的联系，我们最后讨论了值得进一步研究的途径。
Older adults process emotional information differently than young adults, placing more emphasis on pleasant information. Age-related changes in emotional processing have downstream effects on the types of information that are remembered best; whereas young adults remember negative information well, older adults often show greater mnemonic benefits for positive information. Although these cognitive changes have been discussed previously (Mather, 2006; Mather Carstensen, 2005), here we review the neural changes that may mediate these age-related changes. We suggest that changes in older adults' recruitment of prefrontal regions during emotional processing may reflect not only age-related changes in emotion regulation but also changes in self-referential processing. Because little research has examined the links between the neural networks supporting older adults' emotional and cognitive functioning, we conclude with a discussion of avenues meriting further research.
