Motor Speed and Rhythm Assessment
This test measures fine motor speed and temporal regularity. Use your index finger to tap the circle as quickly as possible for 10 seconds. Complete the test for each hand. Results provide neuropsychological assessment indicators to detect cognitive risk and neurological function.

Quantitative indicators of motor speed and rhythm
Motor Speed: Lower tapping speed (taps per second) may indicate motor function decline, which is associated with cognitive risk (including mild cognitive impairment (MCI) and Alzheimer's disease progression).
Brain Age: An estimate based on population norms for motor speed, which typically peaks in the 20s and declines linearly with age (Shimoyama et al.).
Temporal Regularity: Higher tap interval variability (standard deviation) reflects reduced motor timing consistency, which is a sensitive marker of neurological changes before significant speed decline occurs.
Hand Asymmetry: Significant differences between dominant and non-dominant hand performance may indicate lateralized neurological impairment.
