Preparing interactive calculation engine
Test your visual reaction time, working memory, keystroke fluency, and digit span retention. Compare your neural reflexes against global human percentiles.
Complete at least 1 test to generate your live Cognitive Performance Index.
Measure visual-motor reflex transmission latency down to sub-milliseconds across 5 rapid rounds.
Benchmark high-frequency acoustic cutoff (Hz), biological hearing age curves, and 360° binaural spatial localization radar.
Spatial working memory test where numbers 1 to N appear and hide upon first tap. Test your spatial visual chunking.
Hit 30 fast-spawning neon targets. Measures hand-eye mouse latency (ms per target) and precision %.
Memorize flashing white tile patterns as grids expand from 3x3 to 6x6. Test spatial pattern recall.
Benchmark lexical fluency and fine-motor keystroke velocity with real-time accuracy and code mode.
Measure short-term auditory and visual digit retention by memorizing sequential numbers from 1 to 15+ digits.
Visual latency is measured via high-precision `performance.now()` browser timers, bypassing standard JavaScript event loop jitter for accurate millisecond benchmarking.
Percentiles and Cognitive Performance Index (CPI) scores are calculated using normal cumulative distribution functions modeled after global human cognitive datasets.
All test calculations, spatial grids, and memory tokens execute entirely within your local browser. Zero personal test data is transmitted to external telemetry servers.
