Reaction Time Guides & Reflex Research Hub
In-depth scientific articles and performance benchmarks on reaction time, reflexes, and human processing speed.
Every guide is compiled from peer-reviewed research and checked for accuracy before publishing. Figures are cited to their sources, and estimates are labeled as such.
The Neuroscience of Reaction Time: Visual vs. Auditory Neural Pathways
Explore the biological and anatomical journey of sensory stimulus processing — from photoreceptors and cochlear transduction to cerebral motor cortex activation.
Reaction Time in Esports: How Milliseconds Decide Competitive Outcomes
An empirical analysis of reflex benchmarks across tactical FPS (Valorant, CS2), MOBAs, and fighting games. Learn how pro players maintain sub-200ms response latencies.
What Affects Human Reaction Speed? Sleep, Age, Caffeine & Circadian Rhythms
A scientific review of the physiological and environmental variables that alter human neurotransmission speed, fatigue-induced latency, and circadian performance peaks.
Formula 1 Starts: The Science and Training Behind 100ms–200ms Driver Reflexes
How elite Formula 1 drivers achieve lightning race starts under high-G environments. Understand FIA jump-start rules, reaction light mechanics, and simulator drills.
Human Latency vs. System Latency: Display Hz, Mouse Polling Rates & Input Lag
Measure total end-to-end latency from hardware interrupts to display frame redraws. Learn the measurable impact of 60Hz vs. 144Hz vs. 240Hz monitors and polling rates.
The Go/No-Go Test: Response Inhibition, Impulse Control & the Brain's Stop System
Explore the neuroscience of response inhibition — the rIFG, basal ganglia, and what your commission error rate reveals about impulse control and executive function.
The Stroop Effect: Cognitive Interference, Automaticity & the Science of Conflicting Signals
Why does naming an ink color slow when the word spells a different color? Discover the history, neuroscience, and clinical applications of the most replicated finding in cognitive psychology.
WASD Choice Reaction Time: Hick's Law, Motor Planning & the Neuroscience of Directional Responses
How does adding more response options slow your brain down? Explore Hick's Law, spatial stimulus-response compatibility, and why elite gamers narrow the choice RT gap.
The Chimp Test & Visuospatial Working Memory: Why Chimpanzees Outperform Humans
A 2007 Kyoto University study revealed chimpanzees have superior visuospatial short-term memory compared to humans. Discover the Cognitive Trade-Off Hypothesis and what the test actually measures.
Anticipation Timing & the Internal Clock: How the Brain Predicts the Future
Elite batters, goalkeepers, and sprinters rely on anticipatory timing rather than pure reaction speed. Explore Scalar Expectancy Theory, striatal beat-frequency timing, and how to sharpen your internal clock.
