Key Performance Factors

😴

Sleep & FatigueAfter 18 hours awake, reaction speed drops 20–30%. Prioritize 7–9 hours of sleep for peak reflexes across all reaction-based tasks.

☕

Caffeine100mg of caffeine can improve simple and choice reaction speed by 10–20ms, with peak effect ~45 minutes after consumption.

🖥️

Monitor & LatencyA 60Hz monitor adds 16.7ms display latency. Higher refresh rates and wired peripherals reduce total system lag for more accurate readings.

🧮

Hick's LawEach additional choice adds ~50–70ms to reaction time. Simple RT tests pure speed, while choice RT tests decision efficiency.

About These Benchmarks

Population distribution data is derived from CogniArena's aggregated user results for the primary test in this category. Age and professional benchmarks are sourced from published peer-reviewed research. Your percentile ranking shows how your score compares to all CogniArena users — a higher percentile means you outperformed more people. Benchmarks are updated regularly as new data is collected.
