Reaction Time Test vs Number Reaction Test
Reaction Time tests pure reflex — click when the screen changes. Number Reaction adds a visual search component — you must find a target number in a grid before clicking. This converts a reflex task into a combined attention-plus-reflex task.
When to take the Reaction Time Test
Use the Reaction Time Test for an isolated reflex benchmark. There's no searching, no choosing — just see and click.
Take Reaction Time Test →When to take the Number Reaction Test
Use the Number Reaction Test when you want to measure how attention and visual search slow your response. Real-world scanning tasks (e.g., spotting a road sign while driving) map closely to this.

Why does Number Reaction take longer than Reaction Time?
Number Reaction includes a visual search phase before the response. Your eyes must locate the target digit in the grid, which can add 100–300 ms depending on grid size and target position.
Does practicing one improve the other?
Improvements are largely task-specific. Faster Reaction Time scores don't automatically translate to faster Number Reaction, because the bottleneck in each is different (reflex vs. visual search).
