Dear Rene and Florence, thanks so much for these important issues the two of you adress. In cluttering speed control is the basic problem. As is pointed out by Per Alm the basis of these problems in speed control may lie in basal ganglia circuits. For the effect on language production it is important to understand that message generation is based on our knowledge of the world etc. Before we set up our preverbal message we also monitor if this story is the rigth story for this listener at this moment. I always tell my students that this conceptualisator monitor fails to work properly when you drink to much or when you are to tired and makes you tell stories you did not want to tell this person at that moment. Two moments of monitoring are involved here: monitoring covert and overt speech. In generating the preverbal message you have to choose what the best way is to tell this story and what parts of the story have to be deleted or kept untold (covert monitoring). When speech production is to fast, this moment of choice has not happened carefully enough. When a person starts talking before this choice is made, several ideas are still present and produced. Another very important thing is that when we have produced language we monitor if the message was clear enough for the listener (overt monitoring). When attention capcity for monitoring is limited, as in PWC, a person is not capable to monitor if the message was clear to the listener, so he or she takes more attempts to clarify even when the message was already clear to the listener.
