Exam 1 Flashcards
What are the 3 types of stuttering?
- Repetitions
- Prolongations
- Blocks
What are prolongations?
sound where there is a lot of tension or sound is lengthened
What are blocks?
where the system locks up, often happens on bilabial sounds
What are secondary behaviors?
Learned behaviors as a result from struggling behaviors
What are some secondary behaviors?
eye blinks, head nods/movements, foot stomping
When is a person who stutters considered severe?
If they are disfluent in 20% of their words
When are most people disfluent?
At the beginnings of words/sentences/breath groups
TRUE or FALSE: You can cure the person who stutters by treating their surface behaviors?
FALSE - you have the change the person not just the surface behaviors
Why are there so many varying theories about the etiology of stuttering?
because pinpointing etiology is very hard and the theories typically focus on a particular aspect of stuttering
Who created the Diagnosogenic Theory?
Wendell Johnson
What is the Diagnosogenic Theory?
that all children go through a period of disfluency and have disfluencies
-stuttering evolves from a mis-labeling of stuttering that creates the stuttering problem
What is the “Monster Study”?
Mary Tudor told a group of students who didn’t stutter that they were disfluent and told the teachers that if they had any kind of disfluency that they needed to be stopped and disciplined/corrected
-As a result of this study: she found that labeling someone as “stuttering” cause a change in behavior to make these children act like children who stutter
What are the Learning Theories/Anticipatory Struggle?
Thinking of stuttering as a learned behavior
Who created the Cerebral Dominance Theory?
Samuel T. Orton and Leo Edward Travis
What is the Cerebral Dominance Theory?
The belief that left-handedness caused stuttering because the brain was getting mixed signals as far as motor programming
-Later they thought that maybe it wasn’t handedness but sidedness -studies supported and then refuted this belief
What is the Wada Test?
In the 1960s it was a look at the Cerebral Dominance Theory and looking at how it actually suggested a lack of cerebral dominance
What did the Dichotic Listening Tasks do?
Gave researchers a way of looking at cerebral dominance related to stuttering
- Two different signals presented to opposite ears and listener repeated back
- Results: mixed, inconclusive
What were the results of the Brain Imaging Research?
inconclusive - studies are showing different results, some showing activation in right hemisphere and others showing both hemisphere, some showing no difference
What are the difficulties of the Brain Imaging Research?
- Most of the studies that do show differences have been done on adults so we are not sure if the results are because of stuttering or the cause of
- Don’t seem to see any structural difference in people who stutter
What is the Multi-factorial Dynamic Model?
The theory that there are many different factors of stuttering and the different factors come together that cause stuttering
-Weighting or impact of stutters are different (different degrees of factors)
What do most believe is the cause of stuttering?
That it is a multi-factoral dynamic disorder that doesn’t have one single cause but varying degress of factors that mainfest differently in every individual
What do you say when a parent ask “why does my child stutter?”
You tell them that there are many different reasons for stuttering, discuss the multi-factoral model and give them information about the Demands-Capacities Model (-Tell the parents to help the child maximize their capacities for fluent speech, this will not necessarily make your child fluent but helps the child)
