2018 ASHA CONVENTION PROGRAM BOOK • 245 TECHNICAL RESEARCH SESSIONS • SATURDAY DAY/TIME/ LOCATION/ ROOM SESSION/ AREA/ CONTENT/ LEVEL/TYPE TITLE/ AUTHOR(S) ABSTRACT SA 8:00AM-8:30AM Westin, Galleria Tech D 4696 SLP MSD Intermediate Research Phonetic Complexity – An Important Construct for the Assessment of Progressive Dysarthria Mary Salazar, U of Missouri; Mili Kuruvilla-Dugdale, U of Missouri; Antje Mefferd, Vanderbilt U; Jessica Lisenbee, U of Missouri An improved understanding of speech stimuli effects on articulatory performance is needed to optimize dysarthria assessment. This study aimed to evaluate the effects of phonetic complexity on tongue motor performance in talkers with PD and their age- and sex-matched controls. Preliminary results show larger effect sizes for between-group differences in tongue speed and articulatory working space with increased phonetic complexity. SA 8:30AM-9:00AM Westin, Galleria Tech D 4697 SLP MSD Intermediate Research Diagnosis of Childhood Apraxia of Speech Compared to Other Speech Sound Disorders: A Systematic Review Elizabeth Murray, U of Sydney; Jenya Iuzzini-Seigel, Marquette U; Edwin Maas, Temple U; Hayo Terband, Utrecht Inst of Linguistics-OTS, Utrecht U; Kirrie Ballard, U of Sydney Childhood apraxia of speech (CAS) is a motor speech disorder that is difficult to differentially diagnose due to overlapping symptoms with other disorders. We conducted a systematic review of the evidence concerning assessment and diagnosis of CAS compared to other SSDs. We present the overall quality of the research and discriminative features we have to guide further research and practice. SA 9:00AM-9:30AM Westin, Galleria Tech D 4698 SLP MSD Intermediate Research Differential Diagnostic of Childhood Apraxia of Speech: Study on French-Speaking Children Valérie Schott-Brua, U Lyon 1; Genevieve Meloni, U Grenoble Alpes - U de Montréal; Hélène Loevenbruck, U Grenoble Alpes, Laboratoire de Psychologie et NeuroCognition; Anne Vilain, U Grenoble Alpes, GIPSA-lab; Andrea MacLeod, U of Montreal This presentation is a multiple case study about the differential diagnostic of childhood apraxia of speech in French. We investigate the use of diagnostic checklists established on English-speaking children for French- speaking children. We compare results from 4 children with childhood apraxia of speech, 4 phonological disordered children and 27 typically- developing children on a complete assessment protocol. SA 9:30AM-10:00AM Westin, Galleria Tech D 4699 SLP MSD Intermediate Research /patapata/, limb apraxia, & … antonyms??? New Evidence of Cerebellar Deficits in Childhood Apraxia of Speech Caitlin Vose, Arizona St U; Beate Peter, Arizona St U Children with childhood apraxia of speech (CAS) have global difficulties with sequential processing, implying cerebellar dysfunction. Adults with cerebellar lesions have trouble generating antonyms. In children with CAS and controls, we found strong correlations among antonym performance and measures of sequential processing and significant group differences for antonym accuracy and speed, consistent with antonym deficits as a cerebellar CAS trait. SA 10:30AM-11:00AM Westin, Galleria Tech D 4700 SLP MSD Intermediate Research A Multifaceted Analysis of Treatment Gains in Children with CAS Maria Grigos, New York U; Julie Case, New York U; Edythe Strand, Mayo Coll of Medicine Studies have demonstrated improved speech production for children with apraxia using Dynamic Temporal and Tactile Cuing (DTTC). This study further tests the efficacy of DTTC to examine its impact on treated words, generalization to untreated words and maintenance. A multifaceted approach is discussed, which utilizes transcription, kinematic, and acoustic analyses to measure treatment gains and changes in speech motor control. SA 11:00AM-11:30AM Westin, Galleria Tech D 4701 SLP MSD Intermediate Research Comparative Methods for Evaluating Listener Effort Associated with Dysarthric Speech Kathleen Nagle, Seton Hall U; Christian Krommenhoek, Seton Hall U; Defne Abur, Boston U; Cara Stepp, Boston U Dysarthric speech is not always well-described by measures of intelligibility or severity. The burden associated with listening to dysarthric speech may provide unique, complementary information. However, there is no standard measure of perceived listening effort (PLE) for clinical use. This study compares the reliability and sensitivity of two reported methods of obtaining ratings of PLE for speakers with dysarthria. SA 3:00PM-3:30PM Westin, Galleria Tech F 4702 SLP SLS Intermediate Research Effects of Stimulus Presentation Timing on Degraded Multimodal Sentence Recognition Kimberly Smith, U of South Alabama; Rachel Short, U of South Alabama; Daniel Fogerty, U of South Carolina Many factors influence successful integration of multimodal speech and text signals, although the mechanism is not well understood. This study examined the influence of presentation timing of multimodal stimuli, response-timing and interruption rate on degraded multimodal sentence recognition in college-aged adults. Results suggest presentation timing is critical for simultaneous responses, and higher interruption rates yield better sentence recognition. SA 3:45PM-4:15PM Westin, Galleria Tech A 4703 SLP SLS Introductory Research Semantic Aspects in the Tuesday Narratives of Neurologically-Intact Adults Naama Kenan, Ariel U; Esther Ben-Itzchak, Ariel U; Tamar Yishay, Ariel U; Yael Moshe, Ariel U The current study looked into the Tuesday (ADOS) narratives of neurologically-intact (NI) adults, in order to set up the normative, ultimate performance on this task. Participants were 39 NI adults. Narratives were analyzed with a detailed semantic analysis scheme. Results showed that more than 50% of the targeted concrete details and abstract ideas were included in the narratives of participants. SA 4:15PM-4:45PM Westin, Galleria Tech A 4704 SLP SLS Intermediate Research Prosody Measures for Sarcastic & Literal Remarks in Narrative Contexts during Shared Book Reading Debra Burnett, Kansas St U Acoustic analysis of prosody for literal and nonliteral remarks during narrative discourse provides insight into cues used by listeners. Pairwise variability index describes prosodic cues that may assist children in recognizing instances of humor and sarcasm. Findings related to prosody and comparisons between the use of PVI with measures of mean fundamental frequency and word duration are presented. SA 8:00AM-8:30AM Westin, Carlton 4705 SLP SWAL Advanced Research The Effects of Transcutaneous Electrical Stimulation Pulse Duration on Lingual Palatal Pressure Measures During Swallowing Ali Barikroo, Kent St U VitalStim utilizes long pulse duration for dysphagia rehabilitation. However, limited research in swallowing physiology has suggested that VitalStim may not penetrate deep enough to impact the extrinsic tongue muscles and subsequently modulate the tongue pressure measures during swallowing. The purpose of this study was to compare the effect of varying pulse durations on lingual-palatal pressure measures during swallowing.
