Reaction Time Test

3510152030100

If you’ve ever wondered whether your brain can quickly process visual information or not, this simple quiz is for you! The rule is very simple: When the red circle turns green, tap/click the left mouse button on the screen as fast as possible!

The average reaction time to visual stimulus is around 250ms (milliseconds) and most people are able to achieve up to 200ms with a bit of training. The fastest documented reaction time to visual stimulus is 120 milliseconds, which is an extremely difficult record to beat. If you believe you’ve got what it takes to do better, feel free to upload a video of you doing this test on Youtube and send us the link. You can retake this test as many times as you want with no impact on your final score!

On Aug 3, 2020 - Alain Rancy reached 118ms. Congrats!
According to research, visual cortex response is around 50–70 ms after light enters the eye.
Update: For record applications, a video (camera + fingers) is required. The worst of 5 attempts decides your score to ensure fairness. Contact us via email for details.
Aug 2022 - Oct 2023: Added local leaderboard, enhanced UI, and fixed sorting/performance bugs. Special thanks to Alexandro2k from Mexico.
Introduced Average Reaction Time of Animals. - Dec 1, 2023
Added color options for red-green color blind users. - Aug 31, 2025

World Record Video Rules

World record attempts can be submitted for either the 10-attempts mode or the 100-attempts mode. Please follow these rules for your video submission:

Show Everything: Your video must clearly and continuously show both your hands and the computer screen at the same time. This is mandatory for verification.
No Edits: Submit the original, unedited video file. Any editing will disqualify the attempt.
10-Attempts Mode - No Guessing: For the 10-attempts mode specifically, attempts must be legitimate reactions. Videos showing "pre-firing" or guessing before the signal will not be accepted for this mode record.
Submission: Email your video to admin@arealme.com. Include your name/nickname and score.

Frequently Asked Questions

Can action video games reduce reaction time?

Yes, action video games can significantly reduce reaction times without sacrificing accuracy, extending benefits to various tasks beyond gaming situations.

Does exercise improve reaction times?

Regular physical exercise significantly lowers reaction times, indicating improvements in cognitive function and performance.

Does FPS affect my reaction time test results?

Yes, higher FPS can lead to faster reaction times. For example, a 60Hz monitor refreshes every 16.67ms, while a 144Hz monitor refreshes every 6.94ms, offering quicker visual updates and potentially better reaction times.

Fun Facts

Many researchers have confirmed that reaction to sound is faster than reaction to light, with mean auditory reaction times being 140-160 ms and visual reaction times being 180-200 ms (References).

In the men’s 100m final at the 2024 Paris Olympics, the BBC did an excellent job analyzing the reaction times of the eight athletes to the starting gun. The fastest reaction time was 108ms, achieved by Kerley from the US. However, Kerley only ranked #3 for the bronze medal while Lyles whose reaction time was 178ms, ranked #1 for the gold medal.
