认知功能损伤与情绪失调是影响老年人健康、产生老化疾病（如MCI、AD）的先兆。本项目旨在追踪了解老年人的认知功能与情绪状态的纵向变化过程，发现影响成功老化的敏感指标，为早期识别和训练干预提供依据。研究将利用广西寿乡丰富的长寿老人资源，采用多队列结构化纵向设计（追踪3年），通过系列心理行为测验和ERP实验，考察寿乡老人认知功能和情绪偏见的发展变化规律和电生理机制，多维度探究影响成功老化的敏感因素，为老年健康和临床诊护提供科学依据和数据支撑。

Executive function (EF) and emotional bias are a premonitory of affecting health and aging disease like Mild Cognitive Impairment (MCI) and Alzheimer’s Disease (AD) in aging population. We aim to trace the longitudinal developmental process of EF and emotional bias, to discover sensitive index of successive aging, and to provide evidences for early intervention and cognitive training effect. Thanks to valuable aging resources in Guangxi, the present project will apply structural cohort longitudinal design (tracing 3 years) and a set of neural psychological test and electrophysiological experiment to explore the developmental characteristic and neural mechanisms of EF and emotional bias. We also aim to find sensitive factors and electrophysiological marker of successful aging, to provide robust data support for clinical application and healthy aging.
