Investigating test‐specific practice effects on self‐administered mobile‐based cognitive tasks in two diverse community‐based cohorts
This study found similar trends in test-specific practice effects on mobile-based cognitive tests in two different cohorts. CS and GNG are inherently more complex than SRT, which may explain why test familiarity improved performance three months after baseline. This is congruent with traditional paper-and-pencil neuropsychological tests, wherein tests with complex stimuli show more practice effects relative to simple tasks. Additional research is needed to determine which tests are more sensitive to detecting earliest indicators of cognitive decline, and whether the presence/absence of practice effects itself are clinically meaningful.
