Communication Sciences and Disorders Faculty Articles and Research

Broca’s area is frequently implicated in sentence comprehension but its specific role is debated. Most lesion studies have investigated deficits at the chronic stage. We aimed (1) to use acute imaging to predict which left hemisphere stroke patients will recover sentence comprehension; and (2) to better understand the role of Broca’s area in sentence comprehension by investigating acute deficits prior to functional reorganization. We assessed comprehension of canonical and noncanonical sentences in 15 patients with left hemisphere stroke at acute and chronic stages. LASSO regression was used to conduct lesion symptom mapping analyses. Patients with more severe word-level comprehension deficits …

Rapid Enhancement Of Subcortical Neural Responses To Sine-Wave Speech, Fan-Yin Cheng, Can Xu, Lisa Gold, Spencer Smith

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

The efferent auditory nervous system may be a potent force in shaping how the brain responds to behaviorally significant sounds. Previous human experiments using the frequency following response (FFR) have shown efferent-induced modulation of subcortical auditory function online and over short- and long-term time scales; however, a contemporary understanding of FFR generation presents new questions about whether previous effects were constrained solely to the auditory subcortex. The present experiment used sine-wave speech (SWS), an acoustically-sparse stimulus in which dynamic pure tones represent speech formant contours, to evoke FFR_SWS. Due to the higher stimulus frequencies used in SWS, this …

Stimming Expresses Empathy, Not To Be Masked Or Persecuted: A Scoping Review And Case Study Of The “Double-Empathy Problem” Solved By Recognizing The Autism Language, Kathryn Haas

Student Capstone Papers

This article critically examines autism and autistic stimming through the lenses of neurotypicals and autistics, evaluates confines currently imposed upon autistics by neurotypical society, and synthesizes what autistic leaders have expressed about their experiences striving for inclusion (Gernsbacher, 2017; Milton, 2012). Autistic-led studies are now at the forefront of the neurodiversity movement and are growing in fervor. The following themes were identified: (a) prevalence of autism, (b) the interpretation and measurement of empathy, (c) discovery of genetic factors transformed autistics’ identity, (d) publication of non-genetic factors such as vaccines undermined the legitimacy of the autism language, (e) the problem with …

Verification Of A Mobile Psychoacoustic Test System, Jordana C. Soares, Sangamanatha Veeranna, Vijay Parsa, Chris Allan, Winnie Ly, Minh Duong, Paula Folkeard, Sheila Moodie, Prudence Allen

Faculty Publications

Many hearing difficulties can be explained as a loss of audibility, a problem easily detected and treated using standard audiological procedures. Yet, hearing can be much poorer (or more impaired) than audibility predicts because of deficits in the suprathreshold mechanisms that encode the rapidly changing, spectral, temporal, and binaural aspects of the sound. The ability to evaluate these mechanisms requires well-defined stimuli and strict adherence to rigorous psychometric principles. This project reports on the comparison between a laboratory-based and a mobile system’s results for psychoacoustic assessment in adult listeners with normal hearing. A description of both systems employed is provided. …

Does Whispering Improve Children’S Memory? Comparing Auditory Vigilance And Salience Hypotheses, Christina M. Barnes

Graduate Theses and Dissertations

Oral communication is one of the primary tools children use to learn new information and speech registers can deliver additional meaning to the words someone uses. Cirillo’s (2004) vigilance hypothesis states “Whispering can affect the psychobiological state of recipients, and in particular raise their auditory vigilance” (Cirillo, 2004, p. 76). Building on this theory, the current study investigates the role of whispering and children’s memory by examining a whispering vigilance, whispering salience which focused on the changes between normal and whisper registers, and combined vigilance and salience hypotheses to determine if whispering contributes to the recall of information. Using video …

Identification Of Opportunity Barriers And Supports For Individuals Using Augmentative And Alternative Communication (Aac) And Stakeholders, Meredith K. Gohsman

Rehabilitation Sciences Theses & Dissertations

Characteristics And Causal Factors For The Receptive-Expressive Gap In Typically Developed Spanish-English Adult Bilinguals, Rachael Janelle Javaherian

LSU Master's Theses

A receptive-expressive language gap occurs when a standardized receptive score is statistically greater than an expressive score in either a primary or a second language. In bilingual children, gap studies already exist for determining language impairment. In adults, there are few studies; nevertheless, one needs to distinguish between typical language patterns of bilingualism due to non-pathological loss of L1 skills versus problems resulting from accidents, disease, or age. To this end, the present study attempted to expand findings of studies by Gibson et al. (2012 and 2014) that focused on analysis of the gap and possible factors influencing its existence …

African American English-Speaking Children's Judgments Of Grammaticality: Effects Of Clinical Status And Grammatical Structures, Lori Elizabeth Vaughn

LSU Doctoral Dissertations

African American English (AAE)-speaking children’s ability to judge the grammaticality of sentences was evaluated by their clinical status and grammatical structure. The study originated from a need to understand more about the tense and agreement systems of AAE speakers with specific language impairment (SLI) relative to their typically developing (TD) AAE-speaking peers. Tense and agreement forms are typically excluded from the assessment and treatment of children who speak AAE in fear of misinterpreting a dialect difference as a language disorder. As a result, limited information exists about the tense and agreement systems of AAE-speaking children.

The data were archival and …

Language Variation In The Writing Of African American Students: 6 Factors Predicting Reading Achievement, Lisa Fitton Ph.D., Lakeisha Johnson, Carla Wood, Christopher Schatschneider, Sara A. Hart

Faculty Publications

Purpose

This study aims to examine the predictive relation between measures obtained from African American students' written narrative language samples and reading achievement, as measured by standardized academic assessments.

Method

Written language samples were elicited from 207 African American students in Grades 1–8. The samples were examined for morphosyntactic variations from standardized written Generalized American English (GAE). These variations were categorized as either (a) specific to African American English (AAE) or (b) neutral across AAE and standardized written GAE (i.e., considered ungrammatical both in AAE and in standardized written GAE). Structural equation modeling was employed to then examine the predictive …
