How does the 'stop-signal paradigm' define the mechanical failure of inhibitory control during rapid motor execution?

The stop-signal paradigm defines the mechanical failure of inhibitory control as the inability to cancel a motor response once the process of initiating that movement has crossed a specific point of no return. This framework relies on the race model, which posits that two independent internal processes compete for dominance: a go process that triggers movement and a stop process that halts it. The go process begins when....
