We examined two potential inhibitory mechanisms for stopping a motor response.
Participants performed a standard visual two-choice task in which visual stop signals and no …

What is the neurophysiological locus of inhibition when preparation for a manual response
is countermanded? This paper evaluates data and models that pertain to inhibitory …

Motor inhibition was studied in 3 versions of the stop-signal paradigm, with the stop signal
requiring inhibition of any response (stop-all), a fixed alternative response (stop-change), or …

In our everyday behavior, we frequently cancel one movement while continuing others. Two
competing models have been suggested for the cancellation of such specific actions:(1) the …

In studies of volitional inhibition, successful task performance usually requires the
prevention of all movement. In reality, movements are selectively prevented in the presence …

Recent evidence suggests that inhibition of a motor response may occur as late as the final
stages of response execution. Response production involves central commands for …

The stop-signal task, in which participants must inhibit prepotent responses, has been used
to identify neural systems that vary with individual differences in inhibitory control. To explore …

Control processes underlying reponse inhibition were examined. Six Ss performed a visual
choice reaction task and were occasionally presented with a tone that told them to withhold …

Inhibitory control of eye and hand movements was compared in the stop-signal task.
Subjects moved their eyes to the right or left or pressed keys on the right or left in response …

Volitional inhibition is the voluntary prevention of a prepared movement. Here we ask
whether primary motor cortex (M1) is a site of convergence of cortical activity associated with …
