Now that summer (at least over here in the the northern hemisphere) is over, life is getting back to normal and I want to get back to my efforts to explore the validity of my theory about stuttering. Central to this theory is my belief that there is interaction between speech planning, beliefs, emotions, and the pre-motor and motor programs involved in speech execution. Speaking is meant to happen automatically, but when there is over control of planning words and how to say them, the result might be feelings of anxiety, as well as the wrong signals being sent to the mouth and vocal folds that need to keep vibrating if the speech is going to flow.
Now the question is can this hypothesis be validated through research? Not being a researcher myself, I was very excited to attend a lecture at the NSA Applied Research Symposium by Dr. Jennifer Kleinow of LaSalle University. Kleinow’ et al.’s research related to Smith and Kelly’s Multi-factorial Model of Stuttering, a model that I have referenced many times. The study she presented was designed to see if something in the internal monitoring system of people who stutter is different than in people who speak fluently. What Dr. Kleinow and her colleagues found is that stutterers showed heightened peaks in looking for errors, regardless of whether an error was actually committed. This supports the vicious cycle hypothesis that says stuttering results from over-monitoring the speech plan.
In addition, Kleinow explained that the part of the brain that tells you to stop and start all over might be the anterior cingulate caudate (ACC). This area is a kind of switchboard between the premotor, linguistic, cognitive, limbic system. It is active during speech production, apparently overactive in some people who stutter.
So here we have some support that stuttering is not just a linear problem of blocks, rate of speech, breathing or voice production. It is most likely a problem of system function and is effected, at least in part, by over control of speech planning. There may be other areas of control as well, but this study related to the monitoring of phonological errors before they happen. It is my hope that learning about this connection might encourage those of you who stutter to be aware that planning what you are going to say gets in the way of what you want – the ability to speak without effort.
Earlier this month I attended the Applied Research Symposium: Mapping a Plan for the Future, sponsored by the National Stuttering Association. The purpose of this seminar was not only to advance our understanding of stuttering but also to see how we can apply the findings to treatment for people who stutter. I was happy to have the chance to participate in a dialogue with researchers in the field. It was also very important for me to see if their findings fit into the Dahm Theory. The presentations touched on many aspects of stuttering, including the psychological processes of non-linguistic and language processing, and error-monitoring and motor control. I found it very encouraging that these topics touched upon the factors that I discuss in my model.
If my theory of stuttering is valid, it must be able to explain the variable nature of stuttering. There are some people who stutter in almost all conversations, but this rare, and even these people do not stutter on every word. Most people have times, or situations during which they report that they don’t stutter. Sometimes people can predict when they will stutter, but sometimes it just seems to happen without any warning.
Understanding stuttering would be much easier if we knew what we don’t know. We think in a certain way, so we are not aware of the possibility of thinking differently. This seems confusing, but what is very clear is that by thinking the same way we thought before, keeps us in a state of confusion.
Last week I experienced a first for me in the realm of technology. I had been invited to give my first 3-hour online seminar to the Speech Clinicians attending the Mississippi Speech-Language-Hearing Association Convention. The seminar “Treating Stuttering With Confidence” was held last week.
We’ve added some recent testimonials to the site – we hope you’ll enjoy reading the successes patients and participants in Dynamic Stuttering Therapy have achieved. We’re very proud of each of them and what they have accomplished.
Barbara Dahm will be joining the Afternoon Schmooze, hosted by Nettie Feldman, this Thursday from 2-4 p.m. Israel time (7-9 a.m. Eastern time) to discuss stuttering and therapy methods.
Do you want to speak with ease and confidence? If you do, read on. You are about to find out how every one of my successful clients has accomplished this. If you learn from this, you will better understand what you need to do to create the automatic and natural way of speaking that you desire.
“The King’s Speech” is officially the Oscar winner for this year’s best film, but what I love most about the movie is its effect on people who stutter.
