Abstract
Measuring cognitive function is challenging, as traditional neuropsychological tests lack ecological validity and fail to capture underlying processes. This study investigates the cognitive demands of the Halstead-Reitan Finger Tapping Test (FTT) and introduces novel methods for continuous motor assessment. Using a decomposition approach, we show that attention and cognitive load slow tapping speed and increase variability in dwell phases, while transition phases remain unaffected. Additionally, everyday typing behavior strongly correlates with tapping performance, offering an unobtrusive, objective alternative to FTT. Findings highlight the cognitive component of finger tapping and propose typing-based monitoring as a practical tool for assessing motor-cognitive interplay.
