Audio vs Visual vs Choice Reaction Time Tests
Visual, audio and choice reaction-time tests ask different questions. A visual task measures a response to something you see. An audio task uses a sound. A choice task asks you to identify which response is correct before acting. Our online reaction time test includes these modes alongside Go/No-Go and Color Match.
Choose the mode that matches your question
| Mode | Your task | What to record |
|---|---|---|
| Visual | Respond when the visual signal appears | Valid times and early responses |
| Audio | Respond when the sound plays | Times with the same sound-output setup |
| Choice | Respond in the indicated direction | Correct responses and misses |
| Go/No-Go | Respond to a Go signal and withhold on No-Go | Response times and incorrect actions |
| Color Match | Respond when the displayed color matches the target | Correct recognition and timing |
The table describes this site’s tasks, not clinical assessments. Scores from different modes are not interchangeable, even when they all use milliseconds.
Visual reaction time: one expected response
Start Visual mode, wait for the signal and respond without trying to anticipate its timing. Keep the pointer or responding finger ready. An early response is not evidence of exceptional speed; it occurred before the required signal. Complete the selected rounds and review the median as well as the average.
This is a useful starting mode when you want to track a simple, repeatable response. It does not include aiming at moving opponents, identifying game objects or choosing among complex actions.
Audio reaction time: include the sound path
Audio mode substitutes a sound for the visual signal. Use a comfortable listening level and keep the same headphones or speakers across attempts. Bluetooth, USB and built-in sound systems can deliver audio through different processing paths. A difference between your audio and visual scores cannot be attributed entirely to your sensory response.
If you hear no sound, first check volume, output-device selection and whether the page needs an initial interaction to enable audio. Browser audio policies can restrict playback before a user gesture; see the browser autoplay guidance. Restart the attempt after resolving playback rather than keeping a round where the signal was inaudible.
Choice reaction time: accuracy matters
In this site’s Choice mode, respond to the indicated left or right direction with the matching arrow key or side of the pad. A quick response to the wrong side is a miss. Keep those misses alongside the timing result: a lower average among correct answers can hide a strategy of guessing.
Compare Choice sessions with Choice sessions using the same input and number of rounds. Do not interpret the extra decision step as proof that you have become slower at the simple visual task.
Go/No-Go and Color Match
Go/No-Go adds a requirement to withhold a response on the wrong signal. Waiting correctly is part of the task, even though it produces no fast click to celebrate. Color Match adds recognition of the specified target color. Familiarize yourself with the instructions before recording a session.
These browser modes are practice tasks. They should not be used to diagnose attention, cognition, hearing or vision. Their results also do not establish driving fitness or competitive gaming ability.
How to compare modes usefully
- Complete the same number of rounds in each mode.
- Keep the device and response input constant wherever possible.
- Record the audio output when testing Audio mode.
- Compare errors, median and average rather than only the fastest result.
- Repeat later and keep separate records for each task.

To understand the distinction between rapid repetition and a response to a signal, use our comparison of clicking and reaction tests. Practice each task for its own purpose rather than combining their scores into a single ability rating.
