Applying the stop signal task to speech: Neural and behavioural investigations of proactive and reactive inhibition.

This thesis examined the hypotheses that increased proactive inhibition enhances reactive inhibition; that manual and vocal response inhibition are controlled by common central generators; and that reactive and proactive inhibition are less efficacious in the vocal system. In 4 experiments I found that increased proactive inhibition enhanced reactive inhibition. Second, vocal and manual reactive inhibition are controlled by the right prefrontal-cortex and exhibit similar neurophysiological patterns. Third, vocal responding showed weaker reactive inhibition and possibly as compensatory mechanisms relies on proactive inhibition. These findings could potentially contribute to the treatment of impulsive behaviours, stuttering and Tourette syndrome.
