Since cognitive decline is a major contributor to disability and dependency in older adults, cognitively healthy aging is a global health priority. Traditionally, cognition is viewed as a relatively stable construct and is therefore measured over extended periods of time. However, multiple studies highlight the importance of short-term cognitive variability, as it is closely linked to mood, stress, and cognitive health. However, standard cognitive tests are not designed to capture these short-term fluctuations, as they often require controlled environments and are designed to assess between-person differences. Furthermore, individuals’ personal experiences with their cognition, especially in the short-term and in their daily environment are researched less extensively, despite the literature showing that this is associated with everyday functioning, has a significant impact on daily life, and can predict cognitive decline. Therefore, the first aim of this project is to assess the validity, reliability, and feasibility of cognitive testing in older adults’ daily lives. The second aim is to analyze the association between self-reported and performance-based cognitive assessments, also measured in their daily lives. Ecological momentary assessment will be used for both aims.
