🟢 Go/No-Go Practice — Press vs Withhold

Press on green Go trials; do nothing on red No-Go trials. We report hits and false alarms — not an IQ number. A short inhibition game, not a clinical test.

When a stimulus appears, click only on Go. A click on No-Go is a false alarm. After about 40 trials you see hits and false alarms.
How it works

When a stimulus appears, click only on Go. A click on No-Go is a false alarm. After about 40 trials you see hits and false alarms. Lab go/no-go tasks index one slice of attention and inhibition. This score is neither a diagnosis nor an IQ.
