Professional Human Reaction Time Test

The SHB Reaction Test is a high-precision utility designed to measure your neurological response time in milliseconds (ms). Reaction time is the interval between the presentation of a stimulus (the color change) and the beginning of the response (your mouse click). This tool is widely used by gamers, athletes, and individuals looking to track their cognitive alertness.

What is an Average Reaction Time?

According to various data studies, the average human reaction time to a visual stimulus is approximately200ms to 250ms. However, professional eSports players often achieve scores below 180ms. Your score can be influenced by several factors:

  • Hydration and Fatigue: A tired brain processes visual signals significantly slower.
  • Hardware Latency: Your monitor's refresh rate and your mouse's polling rate can add a few milliseconds to your final score.
  • Age: Research shows that reaction times peak in the early 20s and gradually increase over time.

Customizable Visual Testing

Unique to the SHB ToolBox, we allow you to set your own "GO" color. This is not just for aesthetics; different wavelengths of light can affect how quickly the human eye perceives a change. Some individuals respond faster to Green (high visibility), while others prefer Neon Blue or Red. Use the color picker above to find the stimulus that works best for your eyes.

Scientific Accuracy and Privacy

Our tool uses the high-resolution `Date.now()` timestamp method to ensure accuracy down to a single millisecond. To ensure zero network latency during your test, the logic is executed entirely within your browser. This also means your reaction time records are private—stored only in your local browser history—ensuring that SHB ToolBox remains a secure environment for self-improvement.
