Sensorimotor Synchronizer
This page is meant to demonstrate sensorimotor synchronization (SMS)—the ability to align actions with external events. The tool introduces a 150 ms delay between your click and the box changing color. Over repeated clicks, the brain unconsciously adapts sensory calibration timing to compensate for the delay.
Once the delay is removed, if you’ve been sufficiently primed, the box will subtly appear to change color just before before the click. Then, your brain will recalibrate to this new timing and the effect will fade. This showcases how our brains continuously predict and adjust timing to keep perception and action in sync.
I made this after recommending to someone that they try a sonsorimotor synchronization experiement. I then realized I could not find any simple click-and-go demos to demostrate this. The best I could find was REPP documentation on how to set up their tool in a python venv. REPP is a great tool, but I made this because I wanted a working example I could immediately link to. If you know of any other tools out there, let me know. I would love to see them and what features they’ve integrated.
If you’d like to dive deeper into SMS, here are some sources I used, they’re pretty cool:
