Exploring the relationship between mean performance and within-person variability on smartphone-based cognitive testing in adults across the lifespan - NPP—Digital Psychiatry and Neuroscience This study used smartphone-based mobile cognitive tests to explore how consistently people perform across days, which is called intraindividual variability. Participants included two groups: adults and older adults, many with mild cognitive impairment. Results showed that individuals who performed better on average, in both groups, tended to have more consistent scores across days. These findings suggest that mobile cognitive testing may be a tool to provide insight into cognitive functioning, such as cognitive variability. https://www.nature.com/articles/s44277-025-00036-x
