A Cross-Sectional Comparison Of The Effects Of Phonotactic Probability And Neighborhood Density On Word Learning By Preschool Children, Jill R. Hoover, Holly L. Storkel, Tiffany Hogan

Department of Special Education and Communication Disorders: Faculty Publications

Two experiments examined the effects of phonotactic probability and neighborhood density on word learning by 3-, 4-, and 5-year-old children. Nonwords orthogonally varying in probability and density were taught with learning and retention measured via picture naming. Experiment 1 used a within-story probability/across-story density exposure context. Experiment 2 used an across-story probability/within-story density exposure context. Results showed that probability and density interacted to create optimal learning conditions. Specifically, rare/sparse sound sequences appeared to facilitate triggering of word learning. In contrast, the optimal convergence for lexical configuration and engagement was dependent on exposure context. In particular, common sound sequences and dense …

Accuracy Of Perceptually Based And Acoustically Based Inspiratory Loci In Reading, Yu-Tsai Wang, Jordan R. Green, Ignatius S. B. Nip, Ray D. Kent, Jane Finley Kent, Cara Ullman

Department of Special Education and Communication Disorders: Faculty Publications

Investigations of speech often involve the identification of inspiratory loci in continuous recordings of speech. The present study investigates the accuracy of perceptually determined and acoustically determined inspiratory loci. While wearing a circumferentially vented mask connected to a pneumotach, 16 participants read two passages. The perceptually determined and acoustically determined inspiratory loci were compared with the actual loci of inspiration, which were determined aerodynamically. The results showed that (1) agreement across all three judges was the most accurate of the approaches considered here for detecting inspiratory loci based on listening; (2) the most accurate pause duration threshold for detecting inspiratory …

Lip Movement Exaggerations During Infant Directed Speech, Jordan R. Green, Ignatius S. B. Nip, Erin M. Wilson, Antje Mefferd, Yana Yunusova

Department of Special Education and Communication Disorders: Faculty Publications

Purpose: Although a growing body of literature has indentified the positive effects of visual speech on speech and language learning, oral movements of infant directed speech have rarely been studied. This investigation used 3-dimensional motion capture technology to describe how mothers modify their lip movements when talking to their infants.
Method: Lip movements were recorded from twenty-five mothers as they spoke to their infants and other adults. Lip shapes were analyzed for differences across speaking conditions. The maximum fundamental frequency, duration, acoustic intensity, and first and second formant frequency of each vowel were also measured.
Results: Lip movements were significantly …

Articulatory-To-Acoustic Relations In Response To Speaking Rate And Loudness Manipulations, Antje Mefferd, Jordan R. Green

Department of Special Education and Communication Disorders: Faculty Publications

Purpose: This investigation determined the strength of association between tongue kinematic and speech acoustic changes in response to speaking rate and loudness manipulations. Performance changes in the kinematic and acoustic domains were measured using two aspects of speech production presumably affecting speech clarity: phonetic specification and variability.
Method: Tongue movements for the vowels /ia/ were recorded in ten healthy adults during habitual, fast, slow and loud speech using three dimensional electromagnetic articulography. To determine articulatory-to-acoustic relations for phonetic specification, we correlated changes in lingual displacement with changes in acoustic vowel distance. To determine articulatory-toacoustic relations for phonetic variability, we correlated …

Vowel Recognition From Continuous Articulatory Movements For Speaker-Dependent Applications, Jun Wang, Jordan R. Green, Ashok Samal, Tom D. Carrell

Department of Special Education and Communication Disorders: Faculty Publications

A novel approach was developed to recognize vowels from continuous tongue and lip movements. Vowels were classified based on movement patterns (rather than on derived articulatory features, e.g., lip opening) using a machine learning approach. Recognition accuracy on a single-speaker dataset was 94.02% with a very short latency. Recognition accuracy was better for high vowels than for low vowels. This finding parallels previous empirical findings on tongue movements during vowels. The recognition algorithm was then used to drive an articulation-to-acoustics synthesizer. The synthesizer recognizes vowels from continuous input stream of tongue and lip movements and plays the corresponding sound samples …

Orostiff: Face-Referenced Measurement Of Perioral Stiffness In Health And Disease, Shin-Ying Chu, Steven M. Barlow, Douglas Kieweg, Jaehoon Lee

Department of Special Education and Communication Disorders: Faculty Publications

A new device and automated measurement technology known as OroSTIFF is described to characterize non-participatory perioral stiffness in healthy adults for eventual application to patients with orofacial movement disorders associated with neuromotor disease, traumatic injury, or congenital clefts of the upper lip. Previous studies of perioral biomechanics required head stabilization for extended periods of time during measurement which precluded sampling patients with involuntary body/head movements (dyskinesias), or pediatric subjects. The OroSTIFF device is face-referenced and avoids the complications associated with head-restraint. Supporting data of non-participatory perioral tissue stiffness using OroSTIFF are included from 10 male and 10 female healthy subjects. …

Laryngeal Somatosensory Deficits In Parkinson’S Disease: Implications For Speech Respiratory And Phonatory Control, Michael J. Hammer, Steven M. Barlow

Department of Special Education and Communication Disorders: Faculty Publications

Parkinson’s disease (PD) is often associated with substantial impairment of speech respiratory and phonatory control. However, the degree to which these impairments are related to abnormal laryngeal sensory function is unknown. This study examined whether individuals with PD exhibited abnormal and more asymmetric laryngeal somatosensory function compared with healthy controls, and whether these deficits were associated with disease and voice severity. Nineteen PD participants were tested and compared with 18 healthy controls. Testing included endoscopic assessment of laryngeal somatosensory function, with aerodynamic and acoustic assessment of respiratory and phonatory control, and clinical ratings of voice and disease severity. PD participants …

Subthalamic Nucleus Deep Brain Stimulation Changes Speech Respiratory And Laryngeal Control In Parkinson's Disease, Michael J. Hammer, Steven M. Barlow, Kelly E. Lyons, Rajesh Pahwa

Department of Special Education and Communication Disorders: Faculty Publications

Adequate respiratory and laryngeal motor control are essential for speech, but may be impaired in Parkinson's disease (PD). Bilateral subthalamic nucleus deep brain stimulation (STN DBS) improves limb function in PD, but the effects on respiratory and laryngeal control remain unknown. We tested whether STN DBS would change aerodynamic measures of respiratory and laryngeal control, and whether these changes were correlated with limb function and stimulation parameters. Eighteen PD participants with bilateral STN DBS were tested within a morning session after a minimum of 12 h since their most recent dose of anti-PD medication. Testing occurred when DBS was on, …

Department of Special Education and Communication Disorders: Faculty Publications

A new pneumatic tactile stimulator, called the TAC-Cell, was developed in our laboratory to noninvasively deliver patterned cutaneous stimulation to the face and hand in order to study the neuromagnetic response adaptation patterns within the primary somatosensory cortex (S1) in young adult humans. Individual TAC-Cells were positioned on the glabrous surface of the right hand, and midline of the upper and lower lip vermilion. A 151-channel magnetoencephalography (MEG) scanner was used to record the cortical response to a novel tactile stimulus which consisted of a repeating 6-pulse train delivered at three different frequencies through the active membrane surface of the …

A Preliminary Study: Do Alternative Certification Route Programs Develop The Necessary Skills And Knowledge In Assistive Technology?, Sherry Mee Bell, David F. Cihak, Sharon Judge

Communication Disorders & Special Education Faculty Publications

A large number of special education teachers in the United States are prepared in alternative certification programs and insufficient empirical information exists regarding their knowledge of assistive technology. The purpose of this study was to conduct a preliminary investigation of alternatively licensed special education teachers' knowledge, experience, and confidence with assistive technology. One-hundred twenty-three special education teachers who were enrolled in an alternative license program were surveyed. The data indicated a significant positive relation between teachers' knowledge/usage and their confidence with assistive technology (r = .74; p < .01). In addition, the extent to which the teachers' perceived barriers to integrating assistive technology in the classroom were moderated by their level of confidence. The results are presented in the context of building special education teachers' knowledge and skills as well as affective issues regarding assistive technology.

How Do They Cope: Teaching Students With Learning Difficulties In Mainstream Classrooms, Coralyn Dick

Theses : Honours

This study seeks to examine how teachers cope with the demands of teaching students with and without learning difficulties (LD) in mainstream classrooms. The relationship between psychological coping and teachers stress, self efficacy and adaptiveness was examined in a sample of 151 mainstream primary school teachers from Perth, Western Australia. Teaching experience ranged from 1 to 35 years. Three multiple regression analyses were conducted using the psychological constructs of problem-focused coping, emotion-focused coping and avoidant coping as criterion variables. Results indicated that, time management, professional investment, and instructional practices were predictors of problem-focused coping; work related stress was a predictor …

Motivation And Its Impact On The Academic Achievement Of At-Risk Students, Emily Ann Bishop

Graduate Research Papers

Theories demonstrating the relationship between motivational variables and school achievement have substantially increased over the past three decades. This can be of great potential to educators because if students' motivation is more acquiescent to change than their ability, then achievement can be enhanced through practices that positively affect motivational development. Unfortunately, information on how such theories can be applied or utilized is often overlooked. The purpose of this paper is to examine the effectiveness and practical applicability of concepts from motivational theories on the academic achievement of at-risk students.
