Reaction an speed

Whit is a guid reaction time?

There is nae universal cut-off for a guid reaction time. A calibrated study fand an average simple sicht reaction time o 231 ms, or 213 ms efter correctin for hardware delay, but these are reference results, no a rankin for yer browser score. Study

Common questions

Does a lower time mean a quicker response?

Aye, in the same task an wi the same scorin rules. Comparisons across gear need mair care.

Can I uise the corrected study value as a target?

Treat it as context. Yer browser result hasnae had that laboratory's hardware correction applied tae it.

Does this measure aw o ma thinkin speed?

We dinnae turn this task result intae an intelligence score.
