Time estimation is critical for survival and control of a variety of behaviors, in humans and other animals. Time estimation in the hundred-milliseconds range, known as millisecond timing, is involved in motor control, speech generation and recognition, and sensorimotor synchronization (like playing music or finger tapping to a beat). We have developed a mathematical model for finger tapping and made a prediction on a nontrivial feature of this behavior, namely on the amount and asymmetry of the overshoot after a recovering from a perturbation in the stimulus period. In this work we report an experimental validation of our mathematical model based on that prediction.
