Go / No-Go

A classic test of response inhibition. Respond as fast as you can to green targets, but resist responding to red ones. Sounds simple. It's not.

Game Settings

30% no-go trials, moderate pace

See GREEN → TAP!
See RED → DON'T tap!

How to Play

  • GREEN circle: Tap or press SPACE as fast as you can
  • RED circle: Do NOT respond - hold back your impulse
  • Stimuli appear rapidly - stay alert
  • Balance speed with accuracy

The Science

The Go/No-Go task directly measures response inhibition - your ability to suppress a prepotent motor response. This is a core executive function that's often impaired in ADHD and other conditions. Commission errors (false alarms on No-Go trials) indicate difficulty with impulse control.

Key Metrics

  • Hits: Correct responses to Go stimuli
  • False Alarms: Incorrect responses to No-Go stimuli (impulse failures)
  • Reaction Time: Speed of correct Go responses
  • Inhibition Score: Percentage of correctly inhibited No-Go trials
