Go/No-Go Test

The Go/No-Go test is a classic psychological assessment used to measure inhibitory control and impulse regulation. It evaluates your ability to perform an action when a specific stimulus is presented ("Go") and to inhibit that action when a different stimulus appears ("No-Go"). How It Works: Stimuli appear for about a second with short, randomized gaps. You must press space or tap immediately when you see a "Go" signal (e.g., Green), but restrain yourself completely when a "No-Go" signal appears (e.g., Red). Your Score: Average reaction time on correct Go responses — but with a twist. Missed green signals still count: each one adds the full 1000ms presentation window to your total. That total is then divided by the number of correct Go responses. This means you can't game the score by clicking fast on a few and leaving — the missed greens will drag your average up. Why It Matters: This conflict between the urge to act and the need to stop is the core of the assessment. It measures your ability to control impulses and maintain sustained attention under time pressure.
