Stop-Signal + Go/No-Go — 50 Levels
GO on Teal/Blue/Red. Purple=NO-GO (withhold). On some GO trials a ring appears after a delay (STOP). If it appears, abort. SSD adapts toward ~50% failed stops.
How it maps
EYES
Saccade → foveal lock; peripheral expectancy; late inhibitory control on STOP.
BRAIN
Go: premotor/DLPFC→corticospinal. Stop: rIFG, pre-SMA, STN. Tracks SSRT, p(respond|stop), PES, No-Go errors.
TRANSFER
Abort-at-speed: check swings, shot holds, pass pulls, braking decisions.
