The document summarizes recent research on developmental stuttering from brain imaging and physiological studies. It discusses an international conference that brought together groups supporting people who stutter. It also previews ongoing research from Anne Smith studying predictors of chronic stuttering in young children. The research is following children ages 4-5 who stutter and comparing them to normally fluent peers on tasks like hand clapping to study timing ability and brain activity. Initial findings suggest about 60% of children who stutter have unusually poor timing skills compared to their peers.
