Curious about the science behind reaction time? Build a Morso course on the psychology of reflexes.
How This Works
The test measures the time between the box turning green and your click, in milliseconds. Most people fall somewhere in the 200–300ms range — the time it takes a visual signal to travel from your eyes to your brain to your hand. Results vary a lot from attempt to attempt, so a few tries gives a more honest average than one.
Want to understand the actual neuroscience behind it, not just your score? Morso turns any topic — including this one — into a 30-second course.
