Eight Simple Rules For Talking With Preschoolers, Rhea Paul

Communication Disorders Faculty Publications

The article offers eight simple rules that teachers can use to help preschoolers build their vocabularies. It suggests teachers to talk with children to identify topics that interest them. It also recommends teachers to accompany all the routines and activities of the preschool day to enhance the language experience of children. Moreover, it proposes that open-ended questions invites preschoolers to offer lengthier and more detailed responses, thus stimulating their language growth.

The Effects Of Gender And Catechol O-Methyltransferase (Comt) Val108/158met Polymorphism On Emotion Regulation In Velo-Cardio-Facial Syndrome (22q11.2 Deletion Syndrome): An Fmri Study, Ioana L. Coman, Matthew H. Gnirke, Frank A. Middleton, Kevin M. Antshel, Wanda Fremont, Anne Marie Higgins, Robert J. Shprintzen, Wendy R. Kates

Communication Disorders Faculty Publications

Velo-cardio-facial syndrome (VCFS) is caused by a micro-deletion of over 40 genes at the q11.2 locus of chromosome 22 and is a risk factor for the development of schizophrenia and other psychiatric disorders. COMT, one of the genes located in the deleted region, has been considered as a major candidate gene for genetic susceptibility in psychiatric diseases. Its functional polymorphism Val108/158Met has been shown to affect prefrontal function and working memory and has been associated with emotional dysregulation. We utilized a functional magnetic resonance imaging (fMRI) event-related paradigm to asses COMT genotype and gender-moderated effects on the neural activation that …

Hemispheric Differences In Specificity Effects In Talker Identification, Julio Gonza´Lez, Teresa Cervera-Crespo, Conor T. Mclennan

Psychology Faculty Publications

In the visual domain, Marsolek and colleagues (1999, 2008) have found support for two dissociable and parallel neural subsystems underlying object and shape recognition: an abstract-category subsystem that operates more effectively in the left cerebral hemisphere (LH), and a specific-exemplar subsystem that operates more effectively in the right cerebral hemisphere (RH). Evidence of this asymmetry has been observed in priming specificity for linguistic (words, pseudoword forms) and nonlinguistic (objects) stimuli. In the auditory domain, the authors previously found hemispheric asymmetries in priming effects for linguistic (spoken words) and nonlinguistic (environmental sounds) stimuli. In the present study, the same asymmetrical pattern …

Submental Muscle Tissue Compliance During Relaxation, Contraction, And After Tone-Modification Interventions, Heather M. Clark, Nancy Pearl Solomon

International Journal of Orofacial Myology and Myofunctional Therapy

Deviations in muscle tone are presumed to accompany speech motor control deficits in select forms of dysarthria, although there is little confirmation of these associations. For patients experiencing neuromuscular impairments, therapeutic interventions and/or principles have been devised to alleviate tone deviations where they occur and to prevent the development or exacerbation of tone deviations. Potentially therapeutic effects of these interventions on muscle tone in the speech musculature have not been studied empirically. One reason for the paucity of research is that tools for assessing muscle tone in the speech musculature are not generally available. This pilot study explored the feasibility …

Monitoring Carboplatin Ototoxicity With Distortion-Product Otoacoustic Emissions In Children With Retinoblastoma, Shaum Bhagat, Johnnie Bass, Stephanie White, Ibrahim Qaddoumi, Matthew Wilson, Jianrong Wu, Carlos Rodriguez-Galindo

Faculty Publications

ObjectiveCarboplatin is a common chemotherapy agent with potential ototoxic side effects that is used to treat a variety of pediatric cancers, including retinoblastoma. Retinoblastoma is a malignant tumor of the retina that is usually diagnosed in young children. Distortion-product otoacoustic emission tests offer an effective method of monitoring for ototoxicity in young children. This study was designed to compare measurements of distortion-product otoacoustic emissions obtained before and after several courses of carboplatin chemotherapy in order to examine if (a) mean distortion-product otoacoustic emission levels were significantly different; and (b) if criterion reductions in distortion-product otoacoustic emission levels were observed in …

22q11.2 Deletion Syndrome: Are Motor Deficits More Than Expected For Iq Level?, Nancy J. Roizen, Anne Marie Higgins, Kevin M. Antshel, Wanda Fremont, Robert J. Shprintzen, Wendy R. Kates

Communication Disorders Faculty Publications

To examine motor function in children with 22q11.2 deletion syndrome (22q11.2) and a Full Scale IQ (FSIQ) comparable control group. This study was part of a prospective study of neuropsychological function in children 9 to 15 years of age with 22q11.2 and community control subjects and included children from these two populations with comparable FSIQs. Verbal IQs on the WISC-R for 40 children with 22q11.2 (88.4) and 24 community control subjects (87.2) were not different (P=.563). However, the performance IQs were (22q11.2; 81.1 vs community controls; 89.3; P

The Influence Of Language Production, Comprehension, And Pragmatic Judgment On Prosocial Behavior In Children With Language Impairment, Nicole Yvette Weber

Theses and Dissertations

The purpose of this study was to examine the relationship between language skills and prosocial behavior in 37 children with language impairment (LI) and 37 typically developing peers matched for age (ranging from 6;11 to 11;1 years). The influence of gender on this relationship was also considered. Three different subtests of the Comprehensive Assessment of Spoken Language (Carrow-Woolfolk, 1999) were used to evaluate language ability in the areas of language comprehension, language production and pragmatic judgment skills. The Teacher Behavior Rating Scale (C. H. Hart & Robinson, 1996) was used to evaluate prosocial behavior. The current study replicated previous research …

Aging, Spacial Cues, And Single-Versus Dual-Task Performance In Competing Speech Perception, Karen S. Helfer, Jamie Chevalier, Richard L. Freyman

Karen S Helfer

Older individuals often report difficulty coping in situations with multiple conversations in which they at times need to "tune out" the background speech and at other times seek to monitor competing messages. The present study was designed to simulate this type of interaction by examining the cost of requiring listeners to perform a secondary task in conjunction with understanding a target talker in the presence of competing speech. The ability of younger and older adults to understand a target utterance was measured with and without requiring the listener to also determine how many masking voices were presented time-reversed. Also of …

Neural Plasticity And Treatment-Induced Recovery Of Sentence Processing In Agrammatism, Cynthia K. Thompson, Dirk B. Den Ouden, Borna Bonakdarpour, Kyla Garibaldi, Todd B. Parrish

Faculty Publications

This study examined patterns of neural activation associated with treatment-induced improvement of complex sentence production (and comprehension) in six individuals with stroke-induced agrammatic aphasia, taking into account possible alterations in blood flow often associated with stroke, including delayed time-to-peak of the hemodynamic response function (HRF) and hypoperfused tissue. Aphasic participants performed an auditory verification fMRI task, processing object cleft, subject cleft, and simple active sentences, prior to and following a course of Treatment of Underlying Forms (TUR; Thompson et al., 2003), a linguistically based approach for treating aphasic sentence deficits, which targeted objective relative clause constructions. The patients also were …

Samoan Speech Audiometry: Developing Word Recognition Materials For Native Speakers Of Samoan, Emma Lilian Kruger

Theses and Dissertations

Hearing can be evaluated through the presentation of tones or speech. Speech audiometry determines an individual's speech recognition threshold and word recognition score. Traditionally these materials were developed using familiar, frequently used, monosyllabic words. Currently, there are various types of word recognition materials including those which use word lists, short half-lists, and materials which use sentences level stimuli with competing noise. Word recognition materials were first developed in Standard American English; today, materials are now readily available in many other languages. When possible, word recognition materials are developed digitally to standardize their presentation. Currently, no recorded word recognition materials are …

Brain Mapping Of The Mismatch Negativity And The P300 Response In Speech And Nonspeech Stimulus Processing, Skylee Simmons Neff

Theses and Dissertations

Previous studies have found that behavioral and P300 responses to speech are influenced by linguistic cues in the stimuli. Research has found conflicting data regarding the influence of phonemic characteristics of stimuli in the mismatch negativity (MMN) response. The current investigation is a replication of the study designed by Tampas et al. (2005), which studied the effects of linguistic cues on the MMN response. This current study was designed to determine whether the MMN response is influenced by phonetic or purely acoustic stimuli, and to expand our knowledge of the scalp distribution of processing responses to within- and across-category speech …

Frequency Response Of Synthetic Vocal Fold Models With Linear And Nonlinear Material Properties, Stephanie M. Shaw

Theses and Dissertations

Previous studies have shown the importance of cricothyroid muscle activation in altering fundamental frequency in the human voice. Other studies have investigated the non-linear properties of vocal fold tissue and the impact of this non-linearity on frequency response. Several physical models of the vocal folds have been made for research purposes. However, all have been isotropic in nature with linear stress-strain properties. The purpose of this study was to create a physical model with non-linear stress-strain properties to investigate the frequency response of the model as cricothyroid muscle activation was simulated (in other words, as the vocal folds were stretched …

An Acoustic And Perceptual Investigation Of Contrastive Stress In Children, Anita Susan Dromey

Theses and Dissertations

Key aspects of prosody have been studied in adults for a number of years; however, less attention has been paid to the acoustic patterns of prosody in children. Thus, the purpose of the present study was to evaluate how a group of 20 pre-adolescent children use prosody to mark contrastive stress compared to a control group of adult speakers. It was of interest to investigate whether the children's use of prosody differed between boys and girls or the part of speech being emphasized. The prosodic patterns of contrastive stress were evaluated in terms of duration, fundamental frequency, and intensity change …

Variability Of Syntactic Complexity In Persons With And Without Multiple Sclerosis, Kristin Diane Bjorkman

Theses and Dissertations

Several recent studies have suggested that persons with multiple sclerosis (MS) have diminished syntactic complexity. A greater variability in responses to a variety of tasks has also been noted for persons with MS. However, naturalistic data on syntactic complexity and the complexity's variability in persons with MS have not been examined. In the present study, 8 volunteers with MS (age 18-70 years) and 10 adults without MS participated in both a 15-minute conversational language sample and a sentence completion task in two different sessions. No significant differences were found between groups on any measure, and variability within the groups was …

Development Of Psychometrically Equivalent Speech Recognition Threshold Materials For Native Speakers Of Samoan, Jennifer Lane Newman

Theses and Dissertations

The speech recognition threshold (SRT) is an important measure, as it validates the pure-tone average (PTA), assists in the diagnosis and prognosis of hearing impairments, and aids in the identification of non-organic hearing impairments. Research has shown that in order for SRT testing to yield valid and reliable measures, testing needs to be performed in the patient's native language. There are currently no published materials for SRT testing in the Samoan language. As a result, audiologists are testing patients with English materials or other materials not of the patient's native language. Results produced from this manner of testing are confounded …

Accuracy Of English Speakers Administering Word Recognition Score Tests In Mandarin, Kaylene Barrett Polley

Theses and Dissertations

The purpose of this study was to examine the accuracy of English-speakers in determining the word recognition score of native Taiwan Mandarin-speakers. Digitally recorded Mandarin word lists were presented to 10 native Mandarin-speakers from Taiwan (five male, five female), from whom oral and written responses were collected. Oral responses were scored by 30 native English-speakers, 15 of which had no experience with Mandarin and 15 with two to three years of college-level Mandarin courses or equivalent knowledge of Mandarin. The judges who had experience with Mandarin were able to score the WRS tests with 97% accuracy (with scores ranging from …

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

Jill R. Hoover

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 …

Normal Masking Level Difference Parameters For Use In The Clinical Evaluation Of Auditory Processing Disorders, Maria Noelle Burnham

Theses and Dissertations

Masking Level Difference (MLD) tests are an established component of auditory processing test batteries; however, normative data for these tests vary according to procedure. In this study, forty normal, native-English speaking adults between the ages of 18 and 26 were tested for MLD via a newly developed computer software program using both an adaptive procedure (MLDA) and a Bekesy procedure (MLDB). The results from the two procedures were analyzed for sex differences and compared with each other. For both the MLDA and MLDB, the results showed statistically significant sex differences in the masked thresholds used to obtain the MLD (NoSo …

The Relationship Between Acoustic And Kinematic Measures Of Diphthong Production, Gwi-Ok Jang

Theses and Dissertations

The purpose of this study was to examine the correlation between acoustic and kinematic measures of diphthong production in 11 individuals with multiple sclerosis (MS) and 11 neurologically healthy control speakers. The participants produced four diphthongs: /ɔɪ/, /aʊ/, /aɪ/, /eɪ/. These sounds were spoken in a sentence context. Their speech audio signal was recorded with a microphone and their tongue movements were recorded with a magnetic tracking system. The first and second formants (F1 and F2) were computed with acoustic analysis software, and these signals were time-aligned with the vertical and anteroposterior magnet movement records. Pearson correlations between F1 and …

The Elan Event-Related Potential In Children 5 To 12 Years Of Age, Melissa Crandall

Theses and Dissertations

The examination of Event Related Potentials during language processing tasks provides valuable information of how the brain processes language over time. In the current study, the development of the early left anterior negativity (ELAN) was analyzed in young children. Previous research has described the ELAN as a negative waveform elicited during syntactic processing between 200 and 500 ms post linguistic stimuli. Thirty children from 5 to 12 years of age listened to sentences that were linguistically correct, syntactically incorrect, or semantically incorrect. Sentences were presented for right monaural, left monaural, and binaural ear conditions to determine possible differences related to …

Intelligibility Of Electrolarynx Speech Using A Novel Actuator, Brian Madden, Mark Nolan, Ted Burke, James Condron, Eugene Coyle

Conference Papers

During voiced speech, the larynx provides quasi-periodic acoustic excitation of the vocal tract. Following a laryngectomy, some people speak using an electrolarynx which replaces the excitatory function of the absent larynx. Drawbacks of conventional electrolarynx designs include the buzzing monotonic sound emitted, the need for a free hand to operate the device, and difficulty experienced by many laryngectomees in adapting to its use. Despite these shortcomings, it remains the preferred method of speech rehabilitation for a substantial minority of laryngectomees. In most electrolarynxes, mechanical vibrations are produced by a linear electromechanical actuator, the armature of which percusses against a metal …

Language As A Predictor Of Reticence In Children With Language Impairment, Patricia Anne Moses

Theses and Dissertations

This study examined the relationship between language skills and reticence in 37 children with language impairment (LI) and 37 typically developing peers matched for age (ranging from 6;11 to 10;1 years) and gender. Subtests of the Comprehensive Assessment of Spoken Language (E. Carrow-Woolfolk, 1999) were used to evaluate language ability. The Teacher Behavior Rating Scale (C. H. Hart & C. C. Robinson, 1996) was used to evaluate reticence. The current study replicated previous research by documenting significantly higher levels of reticence in children with LI when compared to typical peers. Significant group differences were also found in paragraph comprehension, syntax …

Cervical Vascular And Upper Airway Asymmetry In Velo-Cardio-Facial Syndrome: Correlation Of Nasopharyngoscopy With Mra, Avi G. Oppenheimer, Susan Fulmer, Keivan Shifteh, Ja-Kwei Chang, Allan Brook, Alan L. Shanske, Robert J. Shprintzen

Communication Disorders Faculty Publications

Purpose

Velo-cardio-facial syndrome (VCFS), the most common genetic syndrome causing cleft palate, is associated with internal carotid and vertebral artery anomalies, as well as upper airway asymmetry. Medially displaced internal carotid arteries, often immediately submucosal, present a risk of vascular injury during pharyngeal flap surgery for velopharyngeal insufficiency (VPI). We evaluate the frequency and spectrum of cervical vascular anomalies in a large cohort of VCFS patients correlating MRA with nasopharyngolaryngoscopy in detecting at risk carotid arteries. Furthermore, we assess the relationship with respect to laterality between cervical vascular patterns and the asymmetric abnormalities of these subjects’ upper airways.

Methods

Cervical …
