Vinney, Lisa; Friberg, Jennifer C.; Smyers, Mary – Journal of the Scholarship of Teaching and Learning, 2019
This case study addressed the authors' efforts to design an 8-week small-group independent study (IS) experience that facilitated undergraduate speech-language pathology students' (n=19) higher-level thinking and overall metacognitive awareness. We hoped to encourage both in order to improve students' overall cognitive growth while enhancing their…

Smaoui, Sana; Peladeau-Pigeon, Melanie; Steele, Catriona M. – Journal of Speech, Language, and Hearing Research, 2022
Purpose: Research remains equivocal regarding the links between hyoid movement and penetration-aspiration. The aims of this study were (a) to explore associations between hyoid parameters, laryngeal vestibule closure (LVC) parameters, and penetration-aspiration on thin liquids; and (b) to determine which of these parameters are the strongest…

Krekeler, Brittany N.; Davidson, Kate; Kantarcigil, Cagla; Pearson, William; Blair, Julie; Martin-Harris, Bonnie – Journal of Speech, Language, and Hearing Research, 2022
Purpose: The elements of impaired swallowing biomechanics are visually assessed and scored by clinicians using a standardized and validated tool for assessing type and severity of physiological impairments using the Modified Barium Swallow Impairment Profile (MBSImP). However, the functional anatomical correlates that underly noted impairments…

McKenna, Victoria S.; Hylkema, Jennifer A.; Tardif, Monique C.; Stepp, Cara E. – Journal of Speech, Language, and Hearing Research, 2020
Purpose: This study examined vocal hyperfunction (VH) using voice onset time (VOT). We hypothesized that speakers with VH would produce shorter VOTs, indicating increased laryngeal tension, and more variable VOTs, indicating disordered vocal motor control. Method: We enrolled 32 adult women with VH (aged 20-74 years) and 32 age- and sex-matched…

Yang, Jing – Journal of Child Language, 2018
This study compared the temporal measurements of stop consonants in 29 three- to six-year-old Mandarin-speaking children and 12 Mandarin-speaking adults. Each participant produced 18 Mandarin disyllabic words which contained six stop consonants /p, p?, t, t?, k, k?/ each followed by three vowels /a, i, u/ at the word-initial position in the first…

Everton, Lisa F.; Benfield, Jacqueline K.; Michou, Emilia; Hamdy, Shaheen; Bath, Philip M. – Journal of Speech, Language, and Hearing Research, 2022
Purpose: Information on reliability of outcome measures used to assess the effectiveness of interventions in dysphagia rehabilitation is lacking, particularly when used by different research groups. Here, we report on reliability of the penetration- aspiration scale (PAS) and temporal and clearance measures, determined using videofluoroscopy.…

Park, Yeonggwang; Stepp, Cara E. – Journal of Speech, Language, and Hearing Research, 2019
Purpose: Recent studies have shown that an acoustic measure, relative fundamental frequency (RFF), has potential for the assessment of excessive laryngeal tension and vocal effort associated with functional and neurological voice disorders. This study presents an analysis of the test-retest reliability of RFF in individuals with healthy voices and…

Cheng, Hung-Shao; Buchwald, Adam – Journal of Speech, Language, and Hearing Research, 2021
Purpose: Previous studies have demonstrated that speakers can learn novel speech sequences, although the content and specificity of the learned speech motor representations remain incompletely understood. We investigated these representations by examining transfer of learning in the context of nonnative consonant clusters. Specifically, we…

Samlan, Robin A.; Story, Brad H.; Lotto, Andrew J.; Bunton, Kate – Journal of Speech, Language, and Hearing Research, 2014
Purpose: Computational modeling was used to examine the consequences of 5 different laryngeal asymmetries on acoustic and perceptual measures of vocal function. Method: A kinematic vocal fold model was used to impose 5 laryngeal asymmetries: adduction, edge bulging, nodal point ratio, amplitude of vibration, and starting phase. Thirty /a/ and /?/…

Howell, Peter; Jiang, Jing; Peng, Danling; Lu, Chunming – Brain and Language, 2012
The neural mechanisms used in tone rises and falls in Mandarin were investigated. Nine participants were scanned while they named one-character pictures that required rising or falling tone responses in Mandarin: the left insula and right putamen showed stronger activation between rising and falling tones; the left brainstem showed weaker…

Perrine, Brittany L.; Scherer, Ronald C. – Journal of Speech, Language, and Hearing Research, 2020
Purpose: The goal of this study was to determine if differences in stress system activation lead to changes in speaking fundamental frequency, average oral airflow, and estimated subglottal pressure before and after an acute, psychosocial stressor. Method: Eighteen vocally healthy adult females experienced the Trier Social Stress Test (TSST) to…

Murray, Elizabeth S. Heller; Segina, Roxanne K.; Woodnorth, Geralyn Harvey; Stepp, Cara E. – Journal of Speech, Language, and Hearing Research, 2020
Purpose: Relative fundamental frequency (RFF) is an acoustic measure that is sensitive to functional voice differences in adults. The aim of the current study was to evaluate RFF in children, as there are known structural and functional differences between the pediatric and adult vocal mechanisms. Method: RFF was analyzed in 28 children with vocal…

O'Brien, Jeremy – ProQuest LLC, 2012
Debuccalization is a weakening phenomenon whereby various consonants reduce to laryngeals. Examples include Spanish s-aspiration (s becomes h word-finally) and English t-glottalization (t becomes glottal stop syllable-finally). Previous analyses of debuccalization view it as a lenition process that deletes or manipulates formal phonological…

Azul, David; Neuschaefer-Rube, Christiane – Journal of Speech, Language, and Hearing Research, 2019
Purpose: The purpose of this study was to investigate whether there were indications of restrictions to voice function in our group of gender-diverse people assigned female at birth (GD people[superscript AFAB]) and whether the participants would benefit from professional voice support. Method: We conducted a descriptive, cross-sectional,…

Diaz-Cadiz, Manuel; McKenna, Victoria S.; Vojtech, Jennifer M.; Stepp, Cara E. – Journal of Speech, Language, and Hearing Research, 2019
Objective: Prephonatory vocal fold angle trajectories may supply useful information about the laryngeal system but were examined in previous studies using sigmoidal curves fit to data collected at 30 frames per second (fps). Here, high-speed videoendoscopy (HSV) was used to investigate the impacts of video frame rate and sigmoidal fitting strategy…
