| Measured simple visual reaction time | 231 ms | Includes the study equipment's delay. |
| Hardware-corrected reaction time | 213 ms | The same result after calibration. |
| Analyzed sample | 1,469 adults, ages 18–65 | Community volunteers in Rotorua, New Zealand. |

Reaction time test
Test yourself: reaction time. Follow the instructions and keep your device and input method consistent when comparing runs.
Common questions
Does a lower time mean a faster response?
Yes, within the same task and scoring rules. Comparisons across equipment need more care.
Can I use the corrected study value as a target?
Treat it as context. Your browser result has not received that laboratory's hardware correction.
Does this measure all my thinking speed?
We do not convert this task result into an intelligence score.
