Stuttering

stuttering definition

disorder of speech fluency that interrupts the forward flow of speech

disfluencies heard in the speech of typical speakers

fillers (um, ah)
hesitations
whole word and phrase repetitions or revisions
no tensions or tremors
normal rhythm and stress patterns

stuttering like disfluencies

repetitions
prolongations
blocks
broken words

repetitions

part word or whole word repeated

what causes stuttering?

not fully understood
may be different factors for different people
many theories

factors of stuttering

predisposing
precipitating
perpetuating

predisposing factors

those agents that incline a person to stutter and causes one person to be at a greater risk than another for beginning to stutter
genetic predisposition
underlying neurological differences
language and speech right brain centered
slower motor reactions
ce

precipitating factors

those factors thought to have made stuttering surface or those that brought it to its present state
may or may not be operating at time of evaluation
developmental and environmental

perpetuating factors

those variables that are continuing or maintaining the stuttering at the present time
attitudes of family members
environmental and physical factors that may be reinforcing stuttering
unrealistic expectations
feelings and attitudes about stuttering
antici

development of stuttering

some children are born with a predisposition for stuttering but that the stuttering only emerges if certain developmental and/or environmental factors are present

three factors interact to result in stuttering

constitutional (predisposing factors)
developmental (precipitating)
environmental (precipitating)

About ____ of those who stutter will have a relative who stutters

2/3rds

who is more at risk for stuttering? males or females?

males

_____________ who stutter are more likely to have relatives who stutter

females

_____________ runs in families. children who continue to stutter typically have relatives who continued to stutter.

persistence

predisposing factor
speech and language
children who stutter have a higher probability of also having a...
they are _________________ to grow out of stuttering

speech and/or language deficit
less likely

predisposing factor
arousal
Speech production systems are _____________ to the effects of high arousal

more vulnerable

higher arousal is associated with __________________ and the occurrence of stuttering migh precipitate even greater arousal

speaking

predisposing factor
sensitivity

those who stutter have a more sensitive temperament
more likely to react negatively to criticism and for it to have an impact on their speaking

predisposing factor
sensory motor coordination

those who stutter were significantly slower than the control

predisposing factor
temporal processing of speech

those who stutter perform poorly on central auditory processing tests
have difficulty discriminating small time differences in the speech signals

predisposing factor
central dominance

those who stutter tend to rely on their right hand hemisphere for linguistic processing rather than the left

which hemisphere cannot handle the linguistic information as efficiently?

right

right hemisphere

where negative emotions are processed
negative emotions might interfere with the processing of speech in the right hemisphere which would make disfluency even more likely to occur
those who stutter use this hemisphere more-however this hemisphere is not s

speech and language networks appear to be vulnerable to disruption during...

moments of growth and neural reorganization

precipitating factor
physical development

child is growing rapidly- as child is focuses on other tasks, fluency suffers
other motor tasks compete with fluency

precipitating factor
cognitive development

processes of perceiving, reasoning, imagining, and problem solving
children with cognitive deficits have a higher incidence of stuttering
may not have as good of an ability to recover from stuttering

precipitating factor
social and emotional development

crosstalk
issues of security, self consciousness, and sensitive impairment- life events

self consciousness can begin around the ages of...

3-4

if children develop maladaptive emotional responses to disfluencies, it may lead to...

increased tension and escape/avoidance behaviors as well as persistent stuttering

decrease in fluency when there is a growth in...

language

stuttering typically begins when...

speech and language are developing most rapidly

parents (environmental influence)

parents standards may influence fluency however there is no evidence that the tendencies of the parents cause stuttering

speech and language environment

speech and language usage is influenced by models that child hears
as he tries to imitate models he hears his system may not be capable of the performance

stressful adult speech models

rapid rate of speech
polysyllabic vocabulary
complex syntax
use of two languages in home

stressful speaking situations for child

competition for speaking
frequent interruptions
demand for display of speech
loss of listener attention
hurried when speaking
frequent questions
excited when speaking
many things to say

life events...

influence child's stability and security

normal non-fluency/typical disfluency

go through this between ages 2-5 years old
whole word or phrase repetitions and interjections
repeated just once or twice and is repeated easily
flow of speech not interrupted
no tension in their speech; kid often unaware of it

Why do children go through typical disfluencies?

language demands, motor control demands, cognitive demands, family demands

Why don't some children "outgrow" disfluencies?

predisposing, precipitating, and perpetuating factors

the onset of stuttering usually occurs before the age of...

6

case history

hereditary factor
developmental history- motor, speech, language
health/neurological
psychological/behavioral
family- how does child react? how do parents feel? what triggers stuttering?

speech and language assessment

identify phonological/articulation issues
identify any language issues

difficulties/delays in speech and language development could lead to a diagnosis of __________ instead of _________

cluttering
stuttering

speech sample

gathered from more than one session and more than one setting
ask parents or client to record samples for analysis

Why do you need a representative sample in as many settings as possible?

because stuttering is variable

analysis of a speech sample

total number of disfluencies
frequencies of different types of disfluencies
disfluency index
duration of individual instances of disfluency
speech rate
types and frequencies of secondary behaviors

disfluency indexes

% of disfluent speech present in the sample
determine in several different environments with different speech modes (reading, spontaneous speech, etc.)

to calculate the total disfluencies index:

1. count the total # of words in speech sample
2. count the total # of disfluencies
3. divide the total disfluencies by the total words
4. change to percentage

two basic measures of behaviors

frequency of disfluencies
types of disfluencies

frequency of disfluencies

how often disfluencies occur in a sample
typically represented as the percentage (out of 100) of disfluent words or syllables

types of disfluencies

helps distinguish "normal" interruptions from "stuttered" interruptions
provides indication of the development of the disorder (especially in preschool children)

duration of disfluencies

measures in terms of the numbers of seconds a repetition, prolongation, or block lasts
can also describe the number of iterations in a repetition
measured with a stopwatch, by averaging the samples or by selecting the longest examples of disfluencies to i

severity of disfluencies

describes the physical concomitant behaviors during stuttering (tension, struggle)
combine several aspects of behavior into a single number or score

assessing secondary behaviors

note all unusual movement the client exhibits
note abnormal physiological behaviors-these may affect respiratory, phonatory, articulatory, and prosodic aspects of speech production

primary avoidances

starters
postponments
retrials
circumlocutions
antiexpectancies- speech with accent, etc.

secondary avoidances

reduced verbal output or not taking at all
rely on others to communicate for them

speech rate

want to know overall speech rate
difference of speech rate of fluent segments versus overall rate

a standardized assessment to evaluate stuttering looks at:

frequency
duration
physical concomitants

frequency scale scores

expressed in percent syllables stuttered and converted to scale score of 2-18

duration scale scores

timed to the nearest one tenth of a second and converted to scale scores of 2-18

physical concomitants scale scores

converted to scale scores of 0-20

SSI-4

tally the number of disfluencies in speech and in reading
tallies these at the syllable level, not the word level

SSI-4
obtain the _______ for the three longest disfluencies

mean time

assessing feelings and attitudes

helpful for making treatment decisions
different types of checklists, questionnaires

assess stimulability

assess child's ability to produce fluent speech
use the same techniques that are used in treatment

treatment options

fluency enhancing techniques
modification techniques
combined approach

fluency enhanced on...

parent counseling
direct fluency work

therapy
much depends on...

age, awareness, severity, etc.
