stuttering

[mathhead]

Is there a physiological cause for stuttering (maybe something in the brain not connecting right ??) or is it purely psychological?
I'm sure that I read somewhere that it has a basis in some biological mechanism (for chronic stutterers anyway) though I could be wrong.

Most explanations of the causes of stuttering will include at least threee possible causes, since no one knows for sure. Of these, the physiological (more precisely, neurological) cause is discussed as a probablility. However, some believe it's a learned behavior while others modify that slightly by adding the complnent of anxiety caused by overt criticism of stuttering during childhood.
It does appear that there may be some genetic factor since case studies suggest it runs in families, and produces certain focal abnormalities in persons who stutter

When I first met my sister in law's father he was the worst stutterer that I've met. One simple word could take 12 or more tries. Over the following months this improved so that we would hardly notice it, but where reminded when other visitors unknown to him were at our place.
I took this to indicate that he was anxious with unfamiliar people and perhaps not self confident enough.
Pity, it severely restricted his social life even though he was one of the nicest chaps one could meet.
