Go/No-Go Test
Test your impulse control. Click on green, don't click on red. Measures attention and inhibition.
FAQ
The Go/No-Go test measures response inhibition — your ability to suppress a prepotent response. It tests impulse control, sustained attention, and the speed of your executive functions.
Response inhibition is the ability to stop or suppress an action that is no longer appropriate. It is a core executive function controlled by the prefrontal cortex and is impaired in conditions like ADHD.
The Go/No-Go paradigm is used in ADHD assessment, brain injury evaluation, and impulse control research. Commission errors (clicking on no-go trials) indicate poor inhibitory control.
About this test
The Go/No-Go test measures response inhibition, a core executive function. You must respond quickly to one stimulus while withholding your response to another, testing the balance between speed and impulse control.
How It Works
Green circles mean go (click quickly). Red circles mean no-go (do not click). The test measures your reaction time on go trials, accuracy, and commission errors (false alarms on no-go trials).
Clinical Relevance
This test paradigm is used in clinical neuropsychology to assess ADHD, traumatic brain injury, and frontal lobe function. High commission error rates suggest impaired inhibitory control.
Tips
- Focus on accuracy rather than speed
- Develop a brief pause before responding
- Stay alert throughout — lapses cause errors
- Get enough sleep before testing
