Intervention of Speech Sound Disorders in Preschool and School-Age Children Flashcards
Characteristics of phonologically disordered
children
- Restricted range and frequency of sound segments
- Restricted range and frequency of segmental combinations
- Syllable structure form limited: CVCV
- Restricted range of features, especially affecting PLACE
- Limited range of FRICATIVES
Likelihood of voiced/voiceless confusion
* Limited production of consonant clusters
* Use of glottal stop as a substitute form
* Late developing sounds are more affected than earlier
developing sounds
Treatment program
Comprehensive Treatment Program Components: 8
- Identifying information (report)
- Target behaviors selected for training (goals)
- Establish pretreatment baseline
- Select a specific treatment approach (articulation disorders vs. phonological disorder)
- Identify sequence of training and behavioral procedures - progression from sounds to
connected speech, reinforces, corrective feedback. - Generalization and Maintenance procedures (carry over, family training about prompting and
reinforcing the target responses outside of clinic) - Dismissal criterion (90% accuracy or more)
- Follow-up and booster treatment (e.g. 3 months following treatment, 6 months…)
It is applicable to all clinical settings, across all children, for articulation or phonological disorders
SELECT TARGET BEHAVIORS
Long term vs short term
Target behavior – treatment goals and objectives that aim to teach the child any skill or action
- Short-term objectives – steps towards support and achievement of long-term goals. Skills are
taught within a short period of time (2 weeks to 3 months) - Long-term goals - target overall communication behaviors (e.g. improve age-appropriate
articulation/phonological skills; intelligibility; maintenance over time and in different contexts).
Skills are taught over a longer period of time (6 months to 1 year)
Establish baselines
Baselines – measured rates of treatment in the absence of treatment (Hedge,
1998). Baseline trials provide an opportunity to produce specific sounds in
different word positions in different words ( assessment results may not be as
accurate by the time of treatment, spontaneous improvement may occur).
- Specify treatment targets (e.g. production of /s/ in initial-word position at the
word level) - Prepare the stimulus items (select words to be taught and pictures to represent
those words, modeling may be sufficient to evoke production) - Prepare a recording sheet
- Administer discrete baseline trials – structured opportunity to produce a target
sound in words/phr./sent. (can be evoked or modeled trials). If production
does not improve with modeling – use other procedures (phonetic placement
….).
* Evoked trials for /f/ - Show a picture with the target sound (fish); show four fingers (to evoke
“four”); ask q-ns (what do you see).
* Modeled trials are similar – with added modeling of correct production
Select initial level and sequence of training
- Identify the level of response complexity – appropriate starting point
for therapy (e.g. sound/syllable/word/phrase/sentence level,
consider information from the baseline in terms of modeled and
evoked trials) - Use high frequency words for treatment and generalization (familiar
and meaningful) - Use facilitative phonetic contexts
- Higher level of response complexity increases treatment efficiency,
progress is more rapid
Development of measurable objectives
Define the target behaviors (short-term objectives and long term goals) in
measurable/operational terms
* Measurable objective/goal should consist of the following:
* Response topography or actual skills targeted ( e.g. will produce /s/..)
* Quantification of response (e.g. with 90% accuracy)
* Response mode (e.g. discrimination versus production training)
* Response level (e.g. in words/sentences)
* Response setting (e.g. in the clinic, in child’s home)
* # of sessions in which the target behavior productions are to be documented (e.g. across three
sessions)
* Only observable activities should be measured and documented.
* Observable activities and verbs are: point, repeat, match, name, tell, ask, count,
write, say….. (vs. think, feel, remember, understand, know..)
Writing goals
SMART – popular systems of writing goals
* Specific – clearly defined
* Measurable – observable and written in measurable terms
* Attainable – consider underlying skills important for attainment
* Relevant – realistic, outcome focused
* Time bound – provide a clear time frame for achievement
* Treatment objectives for individual sounds:
* Jonny will produce /s/ and /z/ consonants in initial position in words, with 80 % accuracy, without cueing
* Treatment objectives for phonological error patterns:
* Jonny will demonstrate reduction of final consonant deletion by producing /p, t, k, m/ consonants in the word-final
position, using minimal pairs, with 90 % accuracy
Behavioral Treatment Procedures 7
Shaping
Treatment is accomplished through the use of behavioral treatment
procedures to establish correct production of speech sounds and to
promote generalization/maintenance of correct production
- Shaping – production training that incorporates various behavioral procedures to help
establish sounds in isolation and progress to more complex levels (for children with
difficulty imitating target sounds correctly). - Behavioral procedures:
1. Phonetic placement
2. Successive approximation
3. Modeling
4. Verbal instructions and Prompts
5. Paired stimuli
6. Positive reinforcement
7. Corrective feedback
Phonetic placement
- Phonetic placement – teaching correct articulatory positioning by description and
demonstration.
* Use mirror for placement
* Use tongue depressor for manipulation of articulators
* Visual feedback – spectrographic displays
* Diagrams and pictures of articulatory positions
* Feeling laryngeal vibration
* Manual guidance – physical manipulation of articulators, using tactile-kinesthetic stimulation or
cueing (e.g. shaping child’s or clinician’s lips with fingers, for production of /b/; touching alveolar
ridge with a tongue depressor to indicate place of articulation for /l/).
Successive Approximation
- Successive Approximation (sound shaping) – using sound that a child can already
produce to help him learn a new sound.
* First target a related sound that later can be related to the final target sound (shaping /r/ from /l/).
Modeling
- Modeling – demonstration of the target response . Child’s
response
to modeling is called imitation. Modeling is used in phonetic
placement and successive approximation.
. Verbal instructions and prompts
- Verbal instructions and prompts
* Instructions – verbal stimuli to facilitate actions
* Prompts – cues that help elicit responses.
* Verbal prompts: a). use of vocal emphasis such as increased vocal intensity or duration; b).
Serve to facilitate production of the target sound (e.g. don’t forget the sound at the end of
words)
* Nonverbal/physical prompts (visual cues or stimulation): using signs and gestures to
facilitate visualization of correct production of the target sound (e.g. gesturing tongue –tip
contact against alveolar ridge, articulatory placement for /l/, using hands).
Paired stimuli
- Paired stimuli – pairing of picture stimuli to facilitate correct
production of a target sound in words .
* Identify key words (words in which incorrect sound is produced correctly )
* Select 10 training words to pair with the key word , and create a picture
board with the key word in the center and training words around the key
word (fan-five, fan-fist, fan-fox…)
* Reinforcement is given for correct production and corrective feedback is
given for an incorrect production
* Programmed sentence level follows (e.g. does the fan have five blades? Yes,
the fan has five blades).
Positive reinforcement
and
Corrective feedback
- Positive reinforcement – primary reinforcers (e.g. food and drink)
and social, secondary, reinforcers (e.g. verbal praise, tokens,
stickers). Move from continuous to intermittent reinforcement. - Corrective feedback – verbal and mechanical
Use specific treatment activities
Use specific treatment activities
* Use fun activities to engage children
* Find out child’s interests and find relevant games, materials
* Therapy activities should provide opportunities to practice target
speech sounds.
* Well selected materials increase motivation, cooperation, and
progress.
Generalization
Generalization
* Assess generalization to untrained stimulus items
(production of trained speech sounds in untrained
stimuli (words, phrases..)
* Assess generalization across word positions
* Assess generalization within sound classes (e.g.
manner, place, voice features)and across sound classes
(teaching /s/ resulted in correct production of /l/).
* Assess generalization across situations – e.g. new
conversational partners or a different situation at
home.
Maintenance considerations
Maintenance considerations
* Clinician should select functional speech sounds with a potential for
generalization, from the child’s environment
* Select common everyday words, phrases, questions
* Use naturally occurring reinforcers
* Delay reinforcement, with intermittent schedule
* Invite different people as part of treatment sessions, move treatment out of
treatment room
* Teach self-monitoring skills
* Teach contingency priming – children prime other to pay attention and
reinforce (e.g. mom, did you notice how I said /s/ in that word?)
* Work with family to carry over, do homework, use reinforcement for correct
production, to promote maintenance.
