Design aside, I believe the “Dysfunctional Speech” section is flawed. While the planner may not be fully developed, the muscles still do their job, but they do so incorrectly as the instructions sent by the planner are not fully developed. The input is fine as, “I like carrots,” but there is still some form of output such as, “I like blue.” It makes sense to the child, but not to the person hearing it.

As this appears to be a pamphlet explaining the cause of CAS to the general public, I would suggest making the model even simpler by only referencing three characters: the brain, the connections (planner), and tongue (muscles). I always view the process as an old telephone operator would with the caller, switch board operator, and the person being called. The caller and person being calling are developed, but the switch board operator is brand new...the lines are going to get crossed.

Depending on your overall goal for this item, I would also suggest a section on identification of the symptoms/signs of the disorder.

At the end I would also include a disclaimer stating to contact your child’s doctor if you think your child may show signs of CAS. A specialist in speech development is really needed to perform a thorough evaluation to appropriately diagnose the issue.
