Assessment & Treatment of CAS in School‐Aged Children,” Presented by: Shelley Velleman, PhD, CCC‐SLP, October 7, 2015, Sponsored by CASANA
Overview of Presentation
• CAS most easily identified in young and severe children:
– motor speech symptoms obvious
– major impact on child's output
• With time and intensive, specialized speech-language intervention:
– motor speech symptoms more subtle
– linguistic and literacy symptoms of more concern
3
Overview of Presentation
• Research into treatment inadequate, especially among older/milder children
• Certain principles either demonstrated empirically (in studies) and/or have clinical consensus among CAS specialists
• Purpose of presentation: review what we know/have reason to believe about status and treatment of CAS in school-aged population

Overview of Presentation• Specific challenges in school-aged children
and how to address them
– Residual speech production errors
– Prosodic differences
– Grammatical errors
– Literacy difficulties
– Effective Communication & Advocacy
• Discussion/Q & A
5
Overarching Purpose of Intervention
• Ultimate goal: communicative flexibility in all modalities
– New content
– New structure
– New context
– New combinations of above
• Includes listener awareness and strategies to help listener

Residual Speech Production Errors
• Often sounds usually mastered later: /s/, /z/, /tʃ/, /dʒ/, /θ/, /ð/, /ʒ/, /ɹ/
• May also include /k/, /g/, /l/, /ʃ/
• Inconsistent nasality due to poor timing/ coordination of velum
• Vowel deviations
• Voicing errors
• Often inconsistent
7
Residual Errors: Intervention
• Motoric strategies: explicit practice of challenging speech sequences, contexts
– Distributed, varied, random practice
– Knowledge of performance (communicative success)
– Decreased feedback to encourage self-monitoring

Residual Errors: Intervention
• Practice articulatory gesture patterns (e.g., alveolar-velar; fricative-stop) if needed*
• Phonological knowledge: don’t assume child knows phonemic role of sounds
• Distinctness vs. precise accuracy
• Listener cues if needed

Prosody Challenges
• Excess equal stress
– Sometimes (partially) therapy-induced (iatrogenic)
• Slow, choppy speech
• Pauses in inappropriate places make appropriate pauses less usefullinguistically
15
Prosody Intervention
• Stress Patterns
– Word stress: differentiate stress on different syllables
– Compound word versus phrase stress
– Sentence stress: emphasize key words

Prosody Intervention– Phrase Stress: match phrase vs.
compound word with meaning
Which one is a:
[ˌhɑʔ|ˈdɔg]?
[ˈhɑʔˌdɔg]?
19
Prosody Intervention– Sentence stress: contrastive stress

Prosody Intervention
• Backward build-ups for sentences
HOMEwork
my HOMEwork
ate my HOMEwork
DOG ate my HOMEwork
That DOG ate my HOMEwork.
21
Prosody Intervention– Sentence Stress: wh-questions
Who eats cheese? Mary eats cheese.What does Mary eat? Mary eats cheese.What does Mary do to cheese? Mary eats cheese.Where does Mary eat cheese? Mary eats cheese in the kitchen.

Prosody Intervention
• Pauses at phrase and clause boundaries
The clown (breathe) with the red nose (breathe)juggled 6 balls (breathe) with his feet.
25
Prosody Intervention• Carry over these skills to:
– Reading aloud (mark words/pauses/etc.)
– Controlled conversation (e.g., in therapy)
– Repairs
– Real conversation
• Explicitly train generalization in different contexts (social, linguistic, etc.)
• Review to maintain progress

Semantic & Grammatical Challenges
• Morphology:
– English suffixes - final consonant clusters
– Multisyllabic words - challenging stress patterns
• Sentence formulation
– Word order
– Marking morphology in the right place
– Subject verb agreement31
Grammatical Intervention
• Ease of production order for morphemes:– extra syllable e.g., "ing"; "children"
– added syllable e.g., "horses", "patted", "Joyce’s"
– significant vowel changes e.g., "mice"; "sang"
– vowel-final e.g., "shoes", "chewed", "Moe’s”
– clusters, in order of difficulty
32

Grammatical Intervention
• Irregular nouns and verbs fall into groups; teach together
Ex: diphthong/tense vowel in present tense lax vowel in past tense
Hide/hid, slide/slid, feed/fed, lead/led
33
Semantic & Grammatical Intervention
• Morphology predicts: stress patterns, vowels, consonants. Examples: “-ity”, “ial”, “Ation”

[əˈlɛktɹɪk] [ˌilɛkˈtɹɪsəɾi]

Grammatical Intervention
• Stress differentiates verbs (iambic) from nouns & adjectives (trochaic):
• preSENT vs. PREsent
• perMIT vs. PERmit
35
Grammatical Intervention
• Use Fokes Sentence Builder (or the like) and backward build-ups to systematically practice sentence formulationwith appropriate:– Lexical and phrasal stress– Sentence stress– Pausing– (Intonation)

Literacy Challenges
• Phoneme-grapheme correspondence: w/o good grasp of what phonemes are and how to pronounce them
• Phonological memory & awareness
– Elision
– Blending
– Other mental manipulation of sounds
39
Literacy Challenges
• Encoding (spelling)
• Decoding (reading)
– Spelling/decoding of familiar words: automaticity (may be fine)
– Spelling/decoding of unfamiliar or nonsense words: flexibility; challenging
• Reading comprehension and narrative
– Part-whole

Literacy Therapy
Be aware of task requirements:• Phonetic (auditory) processing (listening,
discriminating)
• Letter-sound correspondence (reading, spelling)
• Motor speech planning (speaking)
• Visual recognition of letters (usually okay)
• Phonological awareness
• Phonological memory/mental manipulation
41
Literacy Therapy
Be aware of task requirements:
Example: Rhyming• Point to word that rhymes with “cat”.
• Do “cat” and “tack” rhyme?
• Do these two written words rhyme?
• Say a word that rhymes with “cat”.
• Say “cat” in Pig Latin
• Say “cat” backwardsStackhouse & Wells (2000)

Literacy Intervention
• Post et al. (1999):
– Vowel errors in reading reflect poor
vowel underlying representations
43
Literacy Intervention• Articulation & phonological awareness together
more efficient intervention (Moriarity & Gillon,
2006)
Hypothesized reasons:
– More grounded phonological representations
upon which to build phonological awareness
– Multi-modal representations better
phonological memory
• Speech-print connections (e.g., LiPS)44

Literacy Intervention
• Reading and spelling
Key symptom of CAS is difficulty merging units into larger wholes
• Sound-by-sound decoding – as in phonics, Association Method – exacerbates this problem
46

Literacy Intervention• Word families
– English spelling is not phonetic BUT there are patterns (e.g., “-tion”, “aught”)
– Teach patterns: “rhymes”/“word families”
“an” spells [æn]
“p” + “an” = [pæn] “t” + “an” = [tæn]
“m” + “an” = [mæn] “c” + “an” = [kæn] Example: Wilson Method, Benchmark
– Actually better for English spelling patterns

Decoding Multisyllabic Words
• Combine with learning higher-level morphemes (Latin, Greek):
– Stress patterns (see above)
– Meanings

Literacy Therapy
• Story grammar: Integration of story components in reading and writing – Visual/tactile cues (e.g., Story Grammar
Marker; Moreau & Fidrych-Puzzo, 1994)
• Organization of other written texts– Comprehension and production

Communication!• Age-appropriate• Listener awareness
– Attend to listener reactions– Repair (including rate)– Highlight meaning
• Cue topic• Stress/articulate unusual, new, key words
(prosody)
55
Communication!• Listener awareness
– Cue grammar • Pauses (prosody)• Redundancy (e.g., “two days ago” as well
as past tense)– Cue sounds if needed
• Motivation– Tie performance to grades– Content academics- and/or peer-related– Set own goals
56

– Ability & willingness to educate others– Awareness of own challenges and needs– Ability & willingness to self-identify and ask
for needs
