Number Memory Test

Test your physical reflexes against visual triggers. Calibrate input delay, monitor refresh rate, and view population distributions.

Measure your auditory response speeds to low-latency synthesized sound waves. Contrast hearing triggers against visual pathways.

Simulate a Grand Prix start gantry. Suppress anticipatory impulse and release motor actions at the exact millisecond lights extinguish.

Map color changes to keys R, G, B, Y. Manage accuracy-speed trade-offs under cognitive decision load with built-in mismatch penalties.

Inhibitory motor control. Click only when green flashes; suppress actions for distractors (Red, Blue, Purple).

Test hand-eye coordination speed. Click targets as they appear and measure your visual-motor response latency.

Benchmark your monitor refresh rate, event polling jitter, and true biological latency stack.

Remember an expanding grid flash sequence, evaluating Miller's Law bounds on working memory capacity.

Memorize illuminated pattern positions inside dynamic scale matrices.

Track independent auditory tone and visual positions shown N steps back, taxing working memory.

Memorize growing word lists and recall them from distractor sets.

Identify missing items completing linear sequences, 2x2 matrices, progressions, and shape analogies.

Mentally rotate grid patterns and match the orientation across timed trials.

Benchmark your mental calculation speed, operator accuracy, and quantitative working memory.

Benchmark boolean logic processing, bitwise arithmetic shift latencies, and base-16 numerical agility.

Isolate semantic interference. Match visual ink colors ignoring the text name values.

Alternate sequences of numbers and letters (1-A-2-B...) to test search speed and cognitive flexibility.

5-stage attention gauntlet: selective focus, impulse control, task switching, sustained vigilance, working memory under distraction.

Track moving target dots among distractors. Evaluates dynamic spatial attention, peripheral vision, and visual working memory.

Complete 5 cognitive stages — reaction, memory, focus, reasoning, precision — for a unified CAI score and archetype.

Assess your circadian profile, run a fatigue Stroop test, and design a light-temperature sanctuary.

Test your clicks-per-second motor stamina over a 10s timeframe, plotting a cadence curve.

Acquire 30 targets on our coordinates canvas, tracking offset errors in pixels.

Click shrinking targets from 80px to 16px. Measures fine motor precision through center offset.

Flick to 15 random targets, measuring speed and click accuracy.

Benchmark your words per minute (WPM) and typing accuracy against profession-based benchmarks.

Generate a personalized workstation blueprint matching your physical geometry and motor alignment.

Classify 20 numbers as ≥50 or <50 against a 2-second timeout. Measures raw information processing speed.

Tower of Hanoi with 4 disks. Move the stack to the target peg — optimal solution is 15 moves.

5 rounds of task scheduling. Maximize points by completing high-value tasks before deadlines.
