What is a sound repetition? - "W-w-w-w-words", "p-p-p-lay"

- also very uncommon amongst people who don't stutter. The only time we would do that is
because we don't know how to pronounce the word or because we are word searching, but it is
very rare.
What is a block? - Complete block before getting the word out. In the event of silent
blocks, the closure is total, halting the flow of air. They obstruct the flow of speech at one or
several locations (tongue, lips, larynx, etc.)

anxiety you feel being a person who stutters may impact your stuttering even more. People may
limit their speech in order to avoid stuttering. They may be hesitant to fully express themselves.
They may feel shame.
What are examples of secondary behaviours that are signs of physical effort/tension? -
Eye blinks, facial grimacing, changes in pitch or loudness, jaw jerking, head movements)
What are examples of typical disfluencies? - - Multisyllabic whole-word and phrase

How do we define stuttering? - An abnormal high frequency and/or duration of
stoppages in the forward flow of speech. These stoppages usually take the form of: a)
, repetitions of sounds, syllables, or one-syllable words b) prolongations of sounds, or c)
blockages or blocks of airflow or voicing in speech.
What are some behaviours of people with typical disfluency? - - No physical tension or
struggle
- No secondary behaviours
- No negative reaction or frustration
- No family history of stuttering
What are some behaviours of individuals who stutter? - - Associated physical tension or
struggle
Secondary behaviours (e.g., eye blinks, facial grimacing, changes in pitch or loudness)
- Negative reaction or frustration
- Avoidance behaviours (e.g., reduced verbal output or word/situational avoidances)
- Family history of stuttering
What is incidence? - The number of NEW cases in a specific time period (regardless of
whether they still have the condition or not).
What is prevalence? - The number of ALL current cases in a specific time period.
How are incidence and prevalence independent from one another? - - A condition can
have a low incidence and higher prevalence (e.g., autism which is a chronic condition with
relatively few new cases diagnosed)
- A condition can have a high incidence but lower prevalence (e.g., common cold: lots of people
get it but it does not last long).
What is the incidence of stuttering? - The incidence of stuttering is typically reported to
be around 5%.
What is the prevalence of stuttering? - The prevalence of stuttering is typically reported
to be around 1%; may be somewhat lower in adults.
Why is the incidence of stuttering higher than prevalence? - Because somewhere
between 60%-80% of kids will outgrow their stuttering, typically within the first 2 years after
onset.
