How This Test Works
What It Measures
Measures inhibitory motor control by presenting colored flashes. Click only when green (Go signal) and suppress responses to red, blue, or purple (No-Go signals). This directly tests your prefrontal cortex response inhibition circuit.
How Scoring Works
Score combines correct Go responses (hits) with incorrectly acted No-Go responses (false alarms). Higher scores indicate stronger impulse control and selective attention.
What Affects Your Results
Your ability to suppress automatic motor responses, current fatigue level, and practice with inhibition tasks all affect performance. Sleep deprivation increases false alarm rates by 30-50%.
