A clear starting point.
Watch the target and respond when it changes. Choose a session length below, from a short sample to an extended practice.
What you’re practising
- Sustained attention over extended periods
- Reaction time to visual stimuli
- Vigilance - remaining alert during long inactive periods
- Impulse control - avoiding false reactions
How the practice works
- A grey box appears on screen
- The box randomly turns black for brief moments
- Click immediately when you see it turn black
- Tests vary from 3-30 minutes - build your endurance
A few things to try
- Stay visually locked on the target area
- Click immediately when the change happens
- False clicks (clicking when nothing changed) hurt more than misses
- Practice builds mental stamina for longer tests
