CHILDREN with HIGHLY UNINTELLIGIBLE SPEECH-SOME CONCERNS • “Critical Age” Hypothesis [5:6][Bishop & Adams] • “Matthew Effects” [Stanovich] • Later Years--Some Common Difficulties • Reading[Comprehension & Fluency] • Spelling & Writing • “Multisyllabicity” • Imprecise Speech & Subtle Errors • Word Finding
_________________________ **Profound EXTENSIVE Omissions Many Substitutions Extremely Limited Repertoires ______________________________ ~Moderate Some Omissions Some Substitutions ________________________________ _______________________ *Severe Many Omissions EXTENSIVE Substitutions Limited Repertoires ___________________________ Mild Omissions Rare Few Substitutions SEVERITY CONTINUUMNote: Distortions & Assimilations may occur at all levels, but Distortions more common for Mild/Moderate Unexpected Assimilations Common for Severe/Profound ______________________________
3-5Years Syllable “Structures” Omissions Rare[by age 4 yrs] [e.g., Final Consonants (by age 2); /s/ Clusters (by age 3, but /s/ may be distorted)] Few “Simplifications” [Most (e.g., Fronting)Eliminated] Intelligibility > 90% “Adult-like” Speech 5-7Years Phonemic Inventory Completed Liquids [4-6 years] “th” [by age 7] Phonetic Distortions [e.g., Lisps- Eliminated by age 7] “Multisyllabicity” “Adult-standard” TYPICAL PERFORMANCE3-7 Years
MAJOR OPTIONS for TREATMENT • Emphasis on Phonemes • “Traditional” [Van Riper] • Least Phonological “Knowledge” [Elbert & Gierut] • Maximal Oppositions [Gierut] • Multiple Oppositions [Williams] • Oral Motor Exercises [e.g.,Marshalla] • Whole Language[Hoffman, Norris, & Monjure] • Phonological Awareness [Gillon] • Phonological PATTERNS[Including Minimal Pairs (Fairbanks) that Contrast child’s actual deviations]
POTENTIAL OPTIMAL “PRIMARY” PHONOLOGICAL TARGET PATTERNS*for BEGINNING CYCLES *Target only those that are CONSISTENTdeviations. Targets must be STIMULABLE, however [otherwise would reinforce inaccurate kinesthetic image] • Word/Syllable Structures [OMITTED Phoneme Segments] • “Syllableness”[i.e., number of vowels/diphthongs] • Compound Words[e.g., cowboy, baseball] • 3-syllable/word combinations[e.g., cowboy hat, baseball bat] • Singleton Consonants[Syllable/Word Structure] • CV [word-initial /p,b,m,w/ if lacking] • VC[voiceless final Stops /p, t, k/; final /m,n/ if lacking] • VCV[e.g., apple] • /s/ Clusters[for omissions, not substitutions/distortions] • Word-initial[e.g., /sp/, /st/, /sm/, /sn/] • Word-final[e.g., /ts/, /ps/] Incorporate phrase: “It’s a [/s/ cluster word]” after child demonstrates facility producing /s/ clusters in production-practice words [typically by 3rd cycle]
PRIMARY TARGETS-2[for BEGINNING CYCLES] • Anterior/Posterior Contrasts[when stimulable] • Velars [if “Fronter”] • Word-final /k/ • Word-initial /k,g/ [occasionally /h/] • Alveolars/Labials [if “Backer”] • Facilitation of Liquids[even if not stimulable] • Word-Initial /l/ [preceded by week of tongue-tip clicking] • Word-Initial /r/[suppress gliding initially] • Exaggerate vowel • Do not blend initially Incorporate /kr/, /gr/ [when child has velars--typically 3rd cycle]
GENERAL COMMENTSRegarding Targets • Approximately 60 mn per PHONEMEtarget • At least 2 phonemes per target PATTERN • Reassess phonology between cycles • Recycle PrimaryPatterns as needed [until begintoemerge in conversation] • Proceed to Secondary Patterns after • Early developing patterns established • /s/ clusters emerging in conversation • Contrastiveuse of Velars & Alveolars • Practice words for Liquids-produced without Glide
POTENTIAL “SECONDARY” TARGETS Target Any of the Following that are still Consistently Lacking/Deficient • Palatals • Singleton Stridents • Other Consonant Sequences • Vowel Contrasts • Voicing Contrasts • Assimilations • Any Remaining Idiosyncratic Patterns Minimal Pair Words especially useful for these
INAPPROPRIATE TARGETS for PRESCHOOLERS Don’t target aspects that phonologically “normal” peers don’t actually produce • Word-final Voiced Obstruents[e.g., /b,d,g,z/] • Unstressed[weak]Syllables[e.g., refrigerator] • “th” [e.g., mouth] • “ng” [e.g., going] • Vocalic /l/ [e.g., ball] Note: Sibilants are appropriate targets for preschoolers only if stridency is lacking [e.g., /t/ for /s/; /s/ cluster reduction], but NOT for LISPS [which maintain stridency and do not have a particularly adverse effect on intelligibility].
TREATMENT SESSION-BASIC STRUCTURE • Review last session’s practice words • Listening activity[approximately 30 seconds] • 15-20 words containing target[NOT carefully selected] • Child must not repeat these words • Slightamplification • Production-practice words[5-6 carefully selected] • Activities for elicitingproductions • use cues/assists/models as needed [Goal is 100%] • child “takes turn” after saying “target” correctly in production-practice word [change activities every 7 or 8 minutes] • Metaphonological Activity[e.g., rhyming] • Probe for next session’s target • Repeatlistening activity[with slight amplification] • Home practice[2 minutes per day]

Intervention Strategies and Activities for Preschoolers with Speech Sound DisordersClassroom Intervention Nancy CreagheadUniversity of Cincinnati
Questions to Consider • Can/should we work on phonology in the preschool classroom? • Can/should work on phonology and language be combined? • Does the child’s severity level affect these decisions? • What is the evidence?
Relationship between Language and Phonology • It has been found that: • Children with phonological disorders are more likely to have language disorders. • Children with language disorders are more likely to have phonological disorders • There is an obvious synergistic relationship between the two – phonology is an aspect of language! • Current theories of language and phonologic acquisition support this relationship.
Assumptions about Intervention • Does work on phonology help language skills? • Does work on language skills help phonology? • Where is it best to target phonology? • In individual phonological therapy? • Concurrently with language therapy? • In naturalistic environments – e.g. the classroom?
Treatment Strategies • Phonology treatment only • Language treatment only • Sequential phonology and language treatment • Simultaneous language and phonology treatment - non integrated • Integrated phonology and language treatment
Implications for Treatment • The possibilities to consider are: • There is generalization across phonology and other language domains • There is no generalization across domains • There is generalization only in one direction, i.e. from phonology to other language domain only or from other language domains to phonology only.
Generalization from language-based intervention to phonologic domain • Hoffman et al.(1990) • 2 children treated by: • Minimal pairs for phonology OR • Story retell for language • Both children made gains in phonology. Child with phonology treatment made slightly greater gains • Child with language treatment made language gains, but child with phonology treatment did not make significant language gains • Tyler et al. (2002) • 20 children treated for morphosyntax and phonology in different consecutive orders • Children who received morphosyntax first performed as well as those who had phonology first. • Suggests consideration of treatment of morphosyntax first • Hoffman (1996)
Little generalization from language to phonology • Tyler and Sandoval (1994) • Six preschoolers with both language and speech sounds disorders • received intervention on language (focused stimulation of narratives), phonology (modified cycles: elicited imitation and minimal pairs) or both • Some generalization from phonology to language • Negligible generalization for language to phonology • Children who received combined approach made greatest gains in both. • Tyler & Waterson ( 1991)
Little generalization from language to phonology • Fey et al. (1994) • 26 children in moderate to profound range for speech sound disorders • Treated grammar, e.g. • Focus on “will” for future time • Focus on “are” as aux and copula • Focus on “is” as aux and copula • Focus on combining sentences with “and”, “but” • No direct effects on phonology
Evidence to date is not conclusive.Possible Explanations for Discrepancies among Studies • Differences in: • Research methodology • Duration of treatment programs • *Treatment methods • *Severity of impairments across studies • Importance of child’s ability to make the sound
Phonological Awareness and Reading Problems • Research indicates that • Children with reading problems often have difficulty with segmentation. • Sound segmentation ability in kindergarten is a strong predictor of later reading ability. • Sound segmentation may be a necessary prerequisite for reading. • Ability to read may improve sound segmentation.
Relationship between Phonological Awareness and Speech Sound Disorders • Webster and Plante (1992) k-2 • Children with normal phonology scored higher than children with speech sounds disorders on 3 of 4 phonological awareness tasks • Performance was correlated with intelligibility • Cowan and Moran (1997) k-2 • Children with mild speech sound disorders scored lower than typical children on the 3 tests. • Performance was not related to specific sound errors • Children with accompanying language problems did not perform more poorly than children without. • BUT some children with speech sounds errors performed better than the typical children. • Severity may be an important factor
Implications regarding Phonological Awareness • Improvement of phonological production? • Improvement of phonological awareness? • Combination of intervention/instruction?
Treatment Approaches for Speech Sound Disorders • Contrast training • Minimal pair opposition • Maximal pair opposition • Selected word practice • “Seizing the moment” • Using books • Using the curriculum • Intervening during play
We have to consider the treatment issues when we plan Phonologic Treatment in Naturalistic Settings – for example: • Patterns/process selection • Sound/word target selection • Stimulability • Facilitating contexts • Intelligibility • Frequency of occurrence of the sound • Developmental appropriateness • Phonological knowledge
PRINCIPLES OF LANGUAGE LEARNING • Children learn language by learning at least four sets of rules: pragmatic, semantic, syntactic,phonologic/graphic. • The language learning process is self-regulated by each child. The child must be cognitively ready for the language function, meaning and structure. • Children learn language in appropriate contexts which are experientially based and meaningful for them. • Children learn language when they have a reason to communicate.
PRINCIPLES FOR LANGUAGE "TEACHING" • The content for language teaching must be meaningful and relevant to the child and sequentially based on normal development. • Pacing must be at the child's own speed. • Sequencing of skills should consider typical development. • Careful observation of each child will allow the child to help us choose meaningful goals. • The best motivator is natural reinforcement for successful communication.
PRINCIPLES FOR LANGUAGE "TEACHING" • The context for language teaching should: • be based on the child's level of cognitive development; • draw from the child's natural environment; • involve interpersonal interaction; • involve active participation on the part of the child; • be larger than life.
Remediation Based on Normal Development • The acquisition of phonemes and phonological rules is not an all-or-non process. accuracy comes gradually and not for one sound at a time. • All exemplars of a phoneme do not have to be practiced for acquisition to occur • Treatment of multiple error patterns in preschool children presents different issues than treatment of older children who have errors on only /r/ or /s/. • There are advantages to working with children in groups. • Like other language rules, phonological rules are learned through the process of communication in natural and meaningful contexts.
Implications for Serving Preschool Children • The preschool classroom provides a natural and meaningful context where communication is required. • Every child does not have to work on only one sound that is chosen as his target. Modeling and practice of a variety of sounds can occur and is in keeping with normal acquisition. • Naturally occurring words can be used for practice words. • Modeling, exposure and the opportunity for practice can be provided. • Children can learn from each other and can be encouraged to try when other children participate.
