Part 3

Question 1

How to determine whether normal dysfluency or sld

Answer 1

Gather evidence on symptoms- inventory of speech bx (use ss4 to analyze), inventory of speech bx under communicative pressure, awareness of fluency disruptions/reactions via parent child interviews, and caregiver and child’s perception of speech

Question 2

What should you look for when observing aberrant bxs?

Answer 2

Stutter free speech
Note typical linguistic loci
Any evidence of avoidance bx?
Undue and long pauses?

Question 3

What should you look for measuring aberrant events?

Answer 3

Type (cluster, prolongation, rep?)
Physical concomitants
Frequency and duration (% syll)

with SSI-4

Question 4

Why do we measure stuttering bx?

Answer 4

compute severity
determine treatment strategy
determine baseline and change
sort out differential dx

Question 5

How to measure stuttering bx?

Answer 5

no universal system

learn one and use it!

Question 6

How many samples should you get? Types? Size?

Answer 6

At least 2, ideally 3 bc varies

Scripted (lower cog level, non gen, limits avoidance) and spontaneous (formulation, generative, promotes avoidance)

150-500 syllables–> eliminate first and last 50 as they get comfortable/are too comfortable

Question 7

What sampling units should be used? Indices?

Answer 7

PSW percent stuttered words
PSS percent syllables stuttered

PSS is better, if PSW can convert to syllables around 1.5/1

Fluency f index: % fluent
Sound prolongation index: # prolongation events
SD/TD ratio: stuttering disfluency

Can also look at adaptation effect
Anticipation effect
