What Actually Affects Your Reaction Time (and What Doesn't)
Sleep, age, hardware, caffeine, screen brightness — here's a no-nonsense breakdown of the factors that move your reaction time, ranked by how much they actually matter.
Gamers vs Non-Gamers: The Real Reaction Time Gap
The gamer reaction time advantage is real, well-documented, and reversible. Here's what the studies actually show, why it happens, and how big the gap really is.
Why Reaction Time Slows With Age (and What You Can Do About It)
Reaction time peaks at 19 and declines by 1–2 ms per year after that. Here's what's actually happening in your nervous system, and which interventions actually blunt the decline.
Input Lag: Why Your Hardware Is Stealing 30 Milliseconds
Your mouse, monitor, and operating system are all adding latency you can't see. Here's where it comes from, how much it costs you, and how to get it back.
A Brief History of Reaction Time Testing
From Donders' 1865 chronoscope to modern web tests, the science of measuring human reaction time has come a long way. Here's the abbreviated story.
