age. This may persist for weeks or months but eventually disappears due to the maturation of the child's nervous system. Children with a family history of stuttering are more likely to develop the disorder than those without. ex.: "Mommy, I am, I am, um, I am..." Usually, this language dysfluency is a transitional stage that most children will leave behind as they master oral communications. At this point, there is little to no need for any therapeutic intervention. The typical occurrence lies between the ages of 18 months and 7 years as children pass through stages of speech dysfluency as they learn how to talk. Those with these types of dysfluencies will exhibit the afore mentioned repetitions about once every 10 sentences Mistiming and stuttering are common ways that developmental dysfluency manifests itself. When a child mistimes, they prolong a certain letter/syllable in the word they are saying, thereby taking much longer for their sentence to be said. Pauses or blocking are another side effect relating to developmental dysfluency. This is when one inserts a silent interval within the word. Revision is similar to this but is the halting completely, mid-flow of a sentence and taking the thought in a different direction. There is evidence to show that this may not only be an issue of speech motor areas but also the auditory cortex. In a MEG study by Beal et al. they found that adults with "persistent developmental stuttering" or PDS, had slower cortical timing than those who spoke completely fluent. This shows us something is wrong in their auditory motor integration. As far as the underlying ailments behind stuttering, It is not well known whether this side effect has to do with "errors in linguistic planning" or issues with "access or retrieval of linguistic elements" and it could very well involve both issues. On occasion, children will go beyond the normal dysfluency patterns. Instances like the previously mentioned example indicate that the child is learning to use language. In contrast, children with stuttering disorder, will likely repeat sounds or one-syllable words three or more times. They may also prolong sounds for two or more seconds. In comparison, stuttering can be seen as a process where a word appears to become "stuck," and the person may grimace, jerk the head or neck as he struggles to overcome the stutter. Characteristics Characteristics of developmental dysfluency include: Repeating phrases (e.g. "he
