Why Reaction Time Matters
Reaction time is a fundamental measure of cognitive and physical performance. It affects everything from everyday activities like driving to high-stakes environments like competitive gaming, professional sports, and emergency response. Regular testing can help you:
- Track the effects of sleep, nutrition, and lifestyle on your cognitive speed.
- Identify peak performance periods during your day.
- Measure improvement from training and practice.
- Benchmark yourself against population averages.
