Response inhibition – the suppression of a
prepotent or ongoing action – is an executive
function central to the regulation of behaviour.
Response inhibition can be assessed in the
laboratory using the Go/No-go or Stop-Signal tasks
which both assess the capacity to withhold an
inappropriate response. In the Go/No-go task,
participants are required to respond rapidly to Go
stimuli but to withhold that response upon No-go
stimuli. In the Stop-Signal task, participants are
required to respond to Go stimuli but to withhold the
response when an auditory stop signal occurs
subsequent to the Go stimulus.
