How is this different from the Reaction Time test?

Visual Reaction uses a color-change stimulus and 10 trials with no practice block; the core Reaction Time test uses a brightness flash with practice trials.

Why discard sub-100ms responses?

Responses that fast are almost certainly anticipated, not genuinely reactive.

Why the median, not the average?

The median resists slow outliers from lapses in attention.

Visual Reaction

How fast do you react to a color change?

~2 min

Measured values depend on your device, input method, display refresh rate, operating system and environment. This is not laboratory-grade measurement.

Visual Reaction

~2 min

What this measures

Visual Reaction measures the median time to respond to a color-change stimulus across 10 trials. It's a direct benchmark of visual sensorimotor speed.

How it works

Wait for the panel to turn blue, then click as fast as you can. Ten trials with randomized foreperiods. Responses under 100ms are discarded as anticipation.

How results are calculated

Your primary score is the median reaction time in milliseconds (lower is better), estimated against population norms.

Accuracy & limitations

Display latency, refresh rate and input device affect results. This is a direct benchmark (Evidence C).
