RESPONSE CONTROL/ 02
Go / no-go test.
React to circles. Hold back on crosses.A short challenge for your response control.
A LITTLE CONTEXT
The art ofdoing nothing.
A go/no-go task asks you to respond to one kind of signal and withhold your response to another. It explores response inhibition: interrupting an action you were ready to make.
In this game you will see 18 circles and 6 crosses, mixed across 24 cues. A circle calls for a response; a cross calls for a pause. Each cue accepts one response, including the short blank interval that follows it.
- 24 cues per round
- Space bar or touch
- False starts and missed cues explained
GOOD TO KNOW
A few answers.
What is a go/no-go test?
It is a task with two signals: one asks you to act and the other asks you to hold back. This browser version uses circles for go and crosses for no-go.
What counts as a false start?
A false start is a response during a cross cue. A miss is a circle cue you did not respond to. Accuracy includes both responding correctly to circles and correctly ignoring crosses.
Why does the game pause when I switch tabs?
We pause when the page becomes hidden so an interruption does not count as a missed cue. Resume replays the current cue.
Can this measure ADHD or other conditions?
No. This is a casual game, not a standardized clinical task. Your results cannot diagnose any condition.
Your best score is a starting point, not a label.
