= Response inhibition
<Response inhibition> is the suppression or cancellation of an action that would otherwise be made. It is one aspect of <inhibitory control>. For example, in a <stop-signal task> a person prepares a button press in response to a go cue, but occasionally receives a later signal to stop. Successful stopping requires a change to an already prepared response.
The delay between go and stop signals matters: a very late stop signal leaves less opportunity for cancellation. Models use performance across delays to estimate <stop-signal reaction time>, rather than directly timing an invisible mental event. <Brain lesion> studies can test whether damage to a region is associated with impaired stopping, while interpretation still depends on task demands and the measurement model.<Stop-signal inhibition disrupted by damage to right inferior frontal gyrus in humans by Adam R.
