The present study revealed that older adults recruit cognitive control processes to strengthen positive and diminish negative information in memory. In Experiment 1, older adults engaged in more elaborative processing when retrieving positive memories than they did when retrieving negative memories. In Experiment 2, older adults who did well on tasks involving cognitive control were more likely than those doing poorly to favor positive pictures in memory. In Experiment 3, older adults who were distracted during memory encoding no longer favored positive over negative pictures in their later recall, revealing that older adults use cognitive resources to implement emotional goals during encoding. In contrast, younger adults showed no signs of using cognitive control to make their memories more positive, indicating that, for them, emotion regulation goals are not chronically activated.
本研究表明,老年人会运用认知控制过程来强化记忆中的积极信息并减少消极信息。在实验1中,老年人在提取积极记忆时比提取消极记忆时进行了更多的精细加工。在实验2中,在涉及认知控制的任务中表现良好的老年人比表现不佳的老年人更倾向于在记忆中偏好积极图片。在实验3中,在记忆编码过程中被分散注意力的老年人在随后的回忆中不再偏好积极图片而非消极图片,这表明老年人在编码过程中会利用认知资源来实现情感目标。相比之下,年轻人没有表现出利用认知控制使他们的记忆更积极的迹象,这表明对他们来说,情绪调节目标并非长期被激活。
