This session is developed by, and presenters invited by Speech Sound Disorders in Children. Using an evidence-based practice framework, this short course will examine clinical decisions suited to children with speech sound disorder. Evidence-based recommendations and case-based assessment data will guide analysis, target selection, goal writing, intervention, and service delivery options. Strategies for translating evidence into practice will be considered. Audience participation is encouraged.

Seminar Outline 1) What is intervention intensity? 2) What do we know about the intensity of intervention for SSD in children? 3) How might SLPs use the evidence on intervention intensity in their everyday management of SSD in children?

The purpose of this study was to compare treatment outcomes between stimulus presentation conditions to children with moderate to severe SSD: a traditional paper presentation versus a computer software generated presentation. The participants were four monolingual kindergarten children with moderate to severe SSD. A multiple baseline across behaviors single subject design was employed in the study. Two non-stimulable, non-cognate sounds from two different manner categories were selected as sound targets. One sound error was treated using paper stimuli presented in a traditional paper table-top presentation (TAB condition) while the other sound error was treated using stimuli presented on the computer (CBI condition). Picture stimuli for both conditions were generated by the SCIP (Sound Contrasts in Phonology) software program. Treatment followed the paradigm described by Williams (2003). The number of treatment sessions, final treatment performance, and highest generalization performance are summarized for both treatment conditions in Table 1. Although conditions were counterbalanced, data are arranged by condition for ease of interpretation.

Purpose: To investigate how speech-language pathologists (SLPs) report involving parents in intervention for phonology-based speech sound disorders (SSDs), and to describe the home practice that they recommend. Further aims were to describe the training SLPs report providing to parents, to explore SLPs? beliefs and motivations for involving parents in intervention, and to determine whether SLPs? characteristics are associated with their self-reported practice. Method: An online survey of 288 SLPs working with SSD in Australia was conducted. Result: The majority of SLPs (96.4%) reported involving parents in intervention, most commonly in providing home practice. On average, these tasks were recommended to be completed five times per week for 10?min. SLPs reported training parents using a range of training methods, most commonly providing opportunities for parents to observe the SLP conduct the intervention. SLPs? place of work and years of experience were associated with how they involved and trained parents in intervention. Most (95.8%) SLPs agreed or strongly agreed that family involvement is essential for intervention to be effective. Conclusion: Parent involvement and home practice appear to be intricately linked within intervention for phonology-based SSDs in Australia. More high-quality research is needed to understand how to best involve parents within clinical practice.

abstract: Childhood Apraxia of Speech (CAS) is a severe motor speech disorder that is difficult to diagnose as there is currently no gold-standard measurement to differentiate between CAS and other speech disorders. In the present study, we investigate underlying biomarkers associated with CAS in addition to enhanced phenotyping through behavioral testing. Cortical electrophysiological measures were utilized to investigate differences in neural activation in response to native and non-native vowel contrasts between children with CAS and typically developing peers. Genetic analysis included full exome sequencing of a child with CAS and his unaffected parents in order to uncover underlying genetic variation that may be causal to the child’s severely impaired speech and language. Enhanced phenotyping was completed through extensive behavioral testing, including speech, language, reading, spelling, phonological awareness, gross/fine motor, and oral and hand motor tasks. Results from cortical electrophysiological measures are consistent with previous evidence of a heightened neural response to non-native sounds in CAS, potentially indicating over specified phonological representations in this population. Results of exome sequencing suggest multiple genetic variations contributing to the severely affected phenotype in the child and provide further evidence of heterogeneous genomic pathways associated with CAS. Finally, results of behavioral testing demonstrate significant impairments evident across tasks in CAS, suggesting underlying sequential processing deficits in multiple domains. Overall, these results have the potential to delineate functional pathways from genetic variations to the brain to observable behavioral phenotypes and motivate the development of preventative and targeted treatment approaches. / Dissertation/Thesis / Doctoral Dissertation Speech and Hearing Science 2018

Two-hundred and seven speech-language pathologists (SLPs) from the US and 335 SLPs from Australia were surveyed about the intervention, service delivery models and intensity of intervention that they provide to children with speech sound disorder. Differences in practices, and implications for evidence-based practice and clinical outcomes, are discussed.

Orientador: Larissa Cristina Berti / Resumo: Introdução: Apesar de as consoantes líquidas virem sendo descritas como segmentos complexos por envolverem a produção concomitante de duplos gestos articulatórios, ponta e dorso, e estarem comumente envolvidas nos processos fonológicos de simplificação, há argumentos contrários a esse respeito (Recasens, 2016), não havendo um consenso na literatura. Objetivo: descrever qualitativamente e quantitativamente a produção típica e os processos de simplificação (substituição de líquida não lateral para lateral, bem como substituição da líquida não lateral por uma semivogal) das consoantes líquidas alveolares do português brasileiro, em crianças de 4 a 9 anos, a partir da análise ultrassonográfica. Baseando-se em evidências advindas de estudos anteriores, as hipóteses assim se definem: as produções típicas de crianças se assemelhariam às dos adultos, caracterizando-se pela presença de duplos gestos; as produções atípicas, as quais envolvem os processos de substituição de líquida não lateral por uma lateral (/ɾ / [l]) e de semivocalização (/r/ [j]) tratam-se de modificações gestuais de redução da magnitude e/ou omissão de um dos gestos e uma fusão gestual, respectivamente. Método: Foram selecionadas de um banco de dados 60 produções (imagens US e áudios) advindas de 10 crianças com produção típica e de 20 crianças com distúrbios dos sons da fala (DSF) envolvendo os processos anteriormente mencionados. Dentre as produções típicas, 10 corresponderam à podução alvo de [l] e 10 correspo...

Objective: to describe qualitatively and quantitatively the typical production and simplification processes (substitution of non-lateral to lateral liquid, as well as substitution of non-lateral liquid by a semivowel) of alveolar liquids consonants from Brazilian Portuguese in children aged 4 to 9 years, based on ultrasound analysis. Based on evidence from previous studies, the hypotheses defined are: children’s typical productions would resemble adults’ productions, characterized by the presence of double gestures; the atypical productions, such as those involving the substitution processes of non-lateral liquids for a lateral one (/ɾ/ [l]) and semivocalization (/ɾ/[j]) are gestural changes of magnitude reduction and/or omission of one of the gestures and a gestural fusion, respectively. Methods: Sixty productions (US images and audios) from 10 children with typical production and 20 children with speech sound disorders (SSD) involving the aforementioned processes were selected from a database. Among the typical productions, 10 corresponded to the target production of [l] and 10 corresponded to the target production of [ɾ]. Among the atypic...
