I am trying to measure finger tapping cued to a rhythmic auditory stimulus. Ideally, I would like to have participants press the space bar on a keyboard to the beat of the stimulus and measure the time between presses and the coefficient of variation of the time between presses. I have looked online for programs to measure this, but have not had much luck. Before taking the time to write a script for this, I'd appreciate any help in obtaining software that already measures this. Thanks!
