Go/No-Go is a classic response inhibition test: click as fast as possible when a green circle appears (Go), but hold back when a red circle appears (No-Go). It trains the prefrontal cortex's ability to suppress impulsive responses — a standard paradigm for assessing executive function.
Click Start — click on green circles, hold back on red ones
❓ FAQ
What does Go/No-Go train?
Go/No-Go primarily trains response inhibition — responding quickly when action is needed, and suppressing impulses when it isn't. This is governed by the right inferior frontal gyrus (rIFG) and anterior cingulate cortex (ACC), core components of executive function closely linked to impulse control and ADHD.
What does a high false alarm rate mean?
False alarms (clicking on No-Go stimuli) reflect weak impulse control — the brain struggles to suppress an already-initiated motor response. ADHD individuals typically show higher false alarm rates. With consistent training, false alarm rates gradually decrease.
How is this different from the Stroop Task?
Both train inhibitory control, but at different levels. The Stroop Task suppresses cognitive interference (word meaning vs. ink color), while Go/No-Go suppresses motor impulses (a prepared click response). Combining both gives more comprehensive training.
