Go / No-Go

Respond as fast as you can to Go targets, but hold back when a No-Go target appears, which trains attention and impulse control. Select a mode below to begin.

▸ Performance reference & timing windows

Mouse / Trackpad (offset –25ms)

Level	Avg Error	Population
Elite	≤ 45 ms	Healthy trained adults
Good	46–80 ms	Healthy adults, functional patients
Mild Impairment	81–120 ms	Subclinical, early PCS, borderline
Moderate	121–220 ms	Active rehabilitation
Significant Deficit	221–340 ms	ADHD, TBI, chronic PCS
Severe	> 340 ms	Acute injury, severe disorder

SD (Timing Variability)

Level	SD	Interpretation
Excellent	≤ 40 ms	Consistent timing, circuit intact
Good	41–80 ms	Mild inconsistency
Impaired	81–120 ms	Cerebellar timing dysmetria
Severely Impaired	> 120 ms	Marked lapses, attention or cerebellar

EARLY = tapping ahead of the beat (over-anticipatory forward model). LATE = processing or conduction delay. HIGH SD with near-normal mean = cerebellar timing dysmetria. Click timing uses pointer-down with a fixed device-latency correction so taps align with sensorimotor synchronization norms.

Graded Symptom Assessment (GSA)

Rate each symptom from 0 (not present) to 6 (most severe). Scores are totalled across four domains and classified as Adequate, Mild, Moderate, or Severe. Use the Export PDF button to save a dated report.
