Mild Cognitive Impairment and Emotion Regulation in Naturalistic Contexts

项目摘要 情绪调节是心理和身体健康的核心决定因素。随着年龄的增长， 他们表现出认知的各个方面的下降，这些认知被认为是有效情绪调节的核心。 尽管如此，老年人通常能够保持他们的情绪健康，这样他们就可以体验到 在日常生活中有更稳定和积极的情绪。然而，目前尚不清楚那些加速的人是否 认知能力下降也保留了这种有效调节情绪的能力。可以想象， 轻度认知障碍（MCI），谁是在发展阿尔茨海默氏症的风险较高，可以补偿 通过利用现有的个人和社会资源来满足他们的情感需求， 目标.然而，当资源被征税或认知障碍变得 更严重。该项目将解决有关认知控制在情绪中的作用的关键问题 调节和描绘的脆弱性来源，在成年后期的情绪失调。在这样做时， 测试依赖于认知要求较低的策略和利用日常生活中的社会关系是否可以缓冲 MCI对老年人情绪健康结果的潜在负面影响。 该项目的总体目标是促进对情感有效性的理解 在MCI和健康认知老化的成年后期调节。的具体目标 项目是（1）确定情绪调节的有效性是否不同，在老年人与MCI（与老年人相比， 健康认知老化的成年人和年轻人），（2）表征情绪调节模式 策略在老年MCI患者中的使用，以及（3）隔离环境，其中老年MCI患者被缓冲 情绪调节困难为了实现这些目标，对老年人（70岁至 84)MCI或正常认知老化和年轻人（20至34岁）将被招募参加三部分 这项研究结合了标准化的实验室任务和日常生活的经验取样。参与者将 完成两次实验室会议。第一次会议将包括一个全面的认知电池（包括 流体和结晶认知的测量）和身体健康和个性的自我报告测量。的 第二阶段将包括一个标准化的情绪调节电影任务，其中情绪结果 （主观体验和行为表达）将在指导参与者减少 悲伤或厌恶使用指定的策略（重新评价或分心）和自我选择的策略。 在这两个实验室会议之间，参与者将完成14天的体验采样， 评估他们的日常情绪体验和情绪调节，跟踪情绪动态和灵活性， 战略运用。最终，这项工作可以帮助改善MCI的生活质量以及健康的老龄化 通过阐明基于现有资源优化情绪调节努力的方法来帮助人口。

Project Summary Emotion regulation is a central determinant of psychological and physical well-being. As individuals age, they show decline in various aspects of cognition thought to be central to effective emotion regulation. Nonetheless, older adults are typically able to maintain their emotional well-being, such that they experience more stable and positive emotions in daily life. It is unclear, however, whether those with more accelerated cognitive decline also retain this ability to effectively regulate their emotions. It is conceivable that those with mild cognitive impairment (MCI), who are at a higher risk of developing Alzheimer's disease, can compensate for declines in cognitive control by harnessing existing personal and social resources to meet their emotional goals. This ability may break down, however, when resources are taxed or if cognitive impairment becomes more severe. The proposed project will address critical questions about the role of cognitive control in emotion regulation and delineate sources of vulnerability for emotion dysregulation in later adulthood. In doing so, it will test whether relying on less cognitively demanding strategies and drawing on social ties in daily life can buffer older adults from the potential negative impact of MCI on emotional well-being outcomes. The overall objective of the proposed project is to advance understanding of the effectiveness of emotion regulation in later adulthood among those with MCI and healthy cognitive aging. The specific aims of the project are to (1) identify whether emotion regulation effectiveness differs in older adults with MCI (versus older adults with healthy cognitive aging and younger adults), (2) characterize patterns of emotion regulation strategy use among older adults with MCI, and (3) isolate contexts in which older adults with MCI are buffered from emotion regulation difficulties. To achieve these aims, a representative sample of older adults (ages 70 to 84) with MCI or normal cognitive aging and younger adults (ages 20 to 34) will be recruited for a three-part study that incorporates both standardized lab tasks and experience sampling of daily life. Participants will complete two laboratory sessions. The first session will include a comprehensive cognitive battery (including measures of fluid and crystallized cognition) and self-report measures of physical health and personality. The second session will include a standardized emotion regulation film task in which emotional outcomes (subjective experience and behavioral expressions) will be assessed after instructing participants to decrease sadness or disgust using an assigned strategy (reappraisal or distraction) and self-selected strategies. Between these two laboratory sessions, participants will complete 14 days of experience sampling that will assess their daily emotional experience and emotion regulation, tracking emotion dynamics and flexibility of strategy use. Ultimately, this work could aid in improving quality of life in MCI and as well as healthy aging populations by illuminating ways to optimize emotion regulation efforts based on one's existing resources.
