• Child’s ENTIRE system is examined as a unique, independent system (“own language”)

• Views child as ACTIVE and CREATIVE learner of the sound system

• Compares SYSTEM to SYSTEM (child:adult)• Maps child:adult system in terms of

phoneme collapses (one-to-many correspondence)

• Child-based rather than adult-based

Systemic PhonologicalSystemic PhonologicalAnalysis of Child Speech Analysis of Child Speech (SPACS)(SPACS)

• Describes idiosyncratic errors not captured by common phonological processes

• Provides a holistic assessment of child’s speech• Phoneme collapses (phonological rules) are seen

as compensatory strategies that child uses to accommodate a limited sound system to the larger adult sound system– these compensatory strategies are organized

according to particular aspects of adult system in terms of PLACE, MANNER, VOICE

• There is “order” in the “disorder”

ComplexityComplexity A Third Optionfor Target Selection

• The distance metric represents a different perspective to target selection that doesn’t rely on the dichotomous characterization of targets as early ~ late; stimulable ~ non-stimulable; known ~ unknown, etc.

A Third Optionfor Target Selection

• Rather, it is based on the function a particular sound has within a given child’s system– Using phoneme collapses that represent

compensatory strategies developed by the child to accommodate a limited phonetic inventory, we can use a distance metric to select those targets that will result in the greatest amount of change in the least amount of time

Distance MetricDistance MetricWilliams (2003, 2005)Williams (2003, 2005)

• Select up to 4 different target sounds from one rule set based on two parameters:– Maximal Distinction:

select targets that are maximally different from child’s error in termsof PVM

– Maximal Classification:select targets from each of the following:

(a) different manner classes (b) different places of production (c) different voicing

Distance MetricDistance MetricBy selecting targets that are more distinct

from the child’s error(maximal distinction)

and are representativeof the sound classes

collapsed across a phoneme collapse (maximal classification),

the target sounds are more salientand therefore predictedto be more learnable.

Distance MetricDistance Metric• Systemic/functional characteristics of target

sounds are specific to each child’s own unique system

• Assumes that the importance of target sounds is broader than the characteristics of the sound itself.

• The function of a sound is dependent on the role it plays in a particular child’s unique sound system and therefore it will vary from child to child.

With the distance metric,targets are the salient

“corner puzzle pieces”that help the child

History of Residual Errors

• From percentage of changes after age 6, it’s clear that improvement only occurs for some phonemes (/r, ɝ, , /

• More than half of the children still in error at age 6 are not going to improve on /s, z, ʃ, ʧ, /– In fact, they will get to practice their error for another

year or two if use developmental norms• In particular, self-correction of /s/ is unlikely;

especially if it is a lateralized distortion

Residual Errors• Need to predict which children with one or more

residual errors will correct them without intervention and which ones will not

• Research suggests that children 5-6 years old who are not stimulable for an accurate production will need intervention; those who are stimulable may self-correct.

• Therefore, may want to do short-term intervention with first graders who are not stimulable in order to make them stimulable and then monitor for change– “jump-start” the process and prevent later intervention

Choosing Challenging Targets for Intervention

• How can we get kids to jump to the norms? How can we achieve 2-3 year gains in 1 year?

• Are we applying our resources in the best possible way?

• Nelson, Camarata, & colleagues suggest we need to consider the level of challenge of task

High and Low Challenge Targets

Low Challenge TargetsCould run risks:

• hold child below optimal learning rates

• child less interested

• child’s ability is greater than their assessment performance

High Challenge TargetsCould frustration discourage the

child?

• YET with rich supports and supportive contexts, child can get RAPID change

• child is positively engaged

• Series of studies by Nelson & colleagues reported that higher challenges were picked up quicker

confront child’s rule by contrasting his/her error with the new target sound(s) to be learned.

• Non-homonymous approaches indirectly address child’s rule with assumption that greater contrastive distinction of word pairs facilitates learning.

Phase I: Familiarization + Production

• Familiarization– Rule– Sounds– Vocabulary

• Production– One treatment set = 20 responses

(5 contrasts x 4 repetitions)

Criteria: Treatment and Generalization

• Treatment Criteria– 70% accuracy across 2 consecutive tx sets (IMIT -

> SPON) Phase 2– 90% accuracy across 2 consecutive tx sets

(Phase 2 -> add new pictures OR move to Phase 3)

• Generalization Criteria– 90% accuracy on target in untrained probe items– If this is met, 50% accuracy on target in

conversation

Phase 2: Contrasts + Naturalistic Activity

• Imitation– Comparison word first, then target word– Slower models, physical prompts, focus (antecedent

event)– Shadowing, set-ups (during)– Feedback (consequent event)– Gradually fade supports; switch order of presentation

• Naturalistic Play Activities– Sound-loaded communication-centered activities– Dense responses (generally at least 20 responses in 5-8

min)

32

Page 33: Time Management Time - Super Duper · Time Management Time Management ASHA (2000) identified “organizing and time management” as one of nine skills that graduate students in SLP/A

Phase 3: Contrasts within Communicative Contexts

• The focused practice and the play are intertwined

• Play games with the contrasts– Away from the computer (Go Fish,

Memory/Concentration, Teacher, What’s Missing?)

– At the computer (Teacher, 20 Questions, $10,000 Pyramid, Hide-a-Pix)

Phase 4: Conversational Recasts

• Develop sound-loaded communicative scenarios– Naturalistic Speech Intelligibility Training

(NSIT)– Immediate recasts (“hotspots”)

Working in Small Groups

• Grouping children together does not require that they areworking on the same goals

• Each child has a turn with their treatment profile

• Tallies can be kept to see which child, or team, has the most points to encourage healthy competition among the children or between groups of children to motivate them

• Each child, or team, takes turns being the “teacher” and “student”

• Use peers to monitor accuracy, give feedback, and provide assistance

• Each child, or team, can “phone a friend” if they need help

Summary of Group TreatmentSummary of Group TreatmentUsing SCIPUsing SCIP

• All children exhibited improvement on their target sounds– The 2 children who received training on w ~ l, r

using MO exhibited moderate to significant improvement in treatment performance

– These children also exhibited generalization of the target sounds to untrained words

Summary of Group TreatmentSummary of Group TreatmentUsing SCIPUsing SCIP

• These results indicate that SCIP was effective in children achieving improvement in treatment and generalization during a brief treatment period of only 10 sessions that were 30 minutes in length within a group setting

Working with SCIPaway from the computer

• Hide the cards in big boxof rice or beans

• Put chip/token on each picture as child produces it

• Play “Go Fish”, “Teacher, Concentration”, and “What’s Missing?”with the cards

What is What is Evidence?Evidence?

Evidence-Based Practice

• Purpose of EBP in clinical intervention is to promote effective protocols while delaying the adoption of unproven protocols, and preventing the adoption of ineffective interventions (McCauley, 2004)

Integrating EBP• Each of the 4 intervention approaches

represents highly credible evidence to support the effectiveness of each treatment approach

• Therefore, users of SCIP will be implementing phonological treatment models that have high levels of evidence that support their effectiveness

– Levels I and II of the EBP framework criteria used to evaluate the quality and credibility of evidence

Practice Based Evidence• SLPs can document their practice based

evidence and answer their own clinical questions about the effectiveness of their interventions with the clients they serve.

– Data collection and graphing features of SCIP provide SLPs theirown database to evaluate the effectiveness of their treatment

– Data can be used to evaluate specific treatment approaches, document clinician accountability, and compare differences in performance across clinical sites.

Using SCIPas a Practice Based Evidence Tool

– Data-tracking options can be used to examine treatment performance with regard to differences in progression through intervention in terms of time spent at imitative and spontaneous levels of production and differences in performance related to specific vowel contexts

– Comparisons can be made across clients and clinical sites with regard to overall performance, number of contrastive word pairs used in treatment, number of treatment sessions, and total treatment time in minutes

• What is thetime investment

for the SLP?• What arethe benefits

for the client?• Is one approach best?
