Stage 01

Auditory Reaction

Enter a randomized silent interval and respond only when a short audio cue is actually heard; early inputs are recorded as false starts.

Stage 02

High-Frequency Threshold

Judge adaptive 8–20 kHz tones mixed with silent catch trials to estimate the highest frequency you can detect reliably on the current setup.

Stage 03

Color Sensitivity

Find one subtly different tile as the randomized color grid expands and its lightness difference becomes progressively smaller.

Stage 04

Angle Estimation

Estimate the angle between two randomly oriented rays with a 1–179° slider while absolute degree error is recorded.

Stage 05

Circle Control

Draw one freehand closed circle with no guide; best-fit radius, radial deviation, closure, coverage, and path efficiency are measured.
