Effects Of Elicitation Method On Functionally Relevant Item Selection In Spanish And English Monolinguals And Bilinguals, Dallin J. Bailey, Esther Barahona Wilkes

Faculty Publications

Purpose: One important decision speech language pathologists make when planning anomia treatment is the identification and selection of the specific vocabulary items to target during therapy. However, this process is not entirely straightforward. Although ‘functional relevance’ has high face validity for the identification of target items, interpretations differ, which may impact which words are selected for therapy. As such, target item selection methods vary, with resulting items impacted by the specific method used. There are also many person-level variables that may impact the functional relevance of specific items, such as the heritage language of the patient or their bilingualism status. …

The Impacts Of Co-Occurring Developmental Language Disorder On The Academic, Interpersonal, And Behavioral Profiles Of Children With Adhd, Kirsten M. Hannig Russell, Sean M. Redmond

Faculty Publications

Purpose: Attention-deficit/hyperactivity disorder (ADHD) is a multifactorial disorder that has been linked to increased risk for behavioral, academic, and interpersonal problems. Developmental language disorder (DLD) has also been linked to poor outcomes in these areas. The presence of co-occurring disorders in children’s profiles is generally associated with poorer outcomes relative to profiles consisting of only one disorder. This study investigated the extent to which co-occurring DLD in children already identified with ADHD presented increased risk for severity of their primary ADHD symptoms, the presence of secondary behavioral problems, and/or increased problems in the tertiary areas of academic performance and interpersonal …

Efficacy Of Complexity-Based Target Selection For Treating Morphosyntactic Deficits In Children With Developmental Language Disorder And Children With Down Syndrome: A Single-Case Experimental Design, Kirsten M. Hannig Russell, Julie L. Wambaugh, John L. Davis, Sean M. Redmond

Faculty Publications

Purpose: Selecting targets for morphosyntactic intervention is a critical compo-nent of treatment planning. The complexity approach suggests that, by treating a complex morphosyntactic target, improvements will occur for the treated structure and for related, simpler structures. This study evaluated the efficacy of the complexity approach for treating morphosyntactic deficits by targeting a complex BE verb question structure for children with developmental language disorder (DLD) and children with Down syndrome (DS) and observing its impact on treated and untreated BE verb structures. We also explored whether etiology impacted our participants’ treatment responses.

Method: Three participants with DLD and three with DS …

Persevering Through Communication Challenges: A Qualitative Descriptive Exploration Of Communication Experiences In Aphasia, Tyson G. Harmon, Camille Williams, Garrett Cardon, William S. Evans

Faculty Publications

Background

People with aphasia often experience activity limitations and participation restrictions despite wanting to engage in communication activities that are satisfying and meaningful. Communication partner support, the complexity of the communication environment, and the thoughts and feelings of people with aphasia have important implications for both language processing and communicative participation. The perspectives of PWA about the role that environmental and personal factors (e.g. thoughts and feelings) play in their communication experiences could inform clinical practice.

Aims

To qualitatively explore the communication experiences of people with aphasia and how environmental demands and personal factors (especially emotional responses) affect these experiences. …

Faculty Publications

Purpose: This study explored the acceptability and impact of Relationship-Centered Communication Partner Training (RC-CPT) in couples impacted by aphasia. In particular, couples considered whether discussing their relationship roles and responsibilities was important and relevant to the changes they desire. Preliminary quasi-experimental data regarding perceived communication confidence and the marriage relationship were also obtained.

Method: Three couples participated in RC-CPT across two sessions. Surveys were used to measure communication confidence and the marital relationship before and after participation in RC-CPT. The quantitative findings were analyzed using descriptive statistics. Couples also participated in a semi-structured interview about the acceptability of RC-CPT, during …

Understanding And Addressing The Individualized Emotional Impact Of Aphasia: A Framework For Speech-Language Pathologists, Tyson G. Harmon

Faculty Publications

Emotion plays an integral role in communication and has long been considered relevant to aphasia rehabilitation. Speech-language pathologists (SLPs), however, may sometimes wonder how or whether to address emotional responses. The purpose of the present tutorial was to (1) present a framework that clinicians can use to understand individualized emotional responses in aphasia and (2) discuss examples of how the framework informs practical strategies that SLPs can use to provide emotional support to PWA. Drawing upon a cognitive-motivational-relational theory of emotions perspective combined with emerging research in aphasia, I show that emotion impacts and is impacted by both language processing …

Effects Of Cognitive And Social Demands On Linguistic Production For People With Moderate, Mild, Or No Aphasia, Tyson G. Harmon, Emily Mcdonald, Kyle Steele

Faculty Publications

Background

Most everyday communication occurs in situations where cognitive and social demands are present. These types of situations may compound language deficits for people with aphasia (PWA). An understanding of the language interference that may occur from cognitive and social demands is an important precursor for assessment and intervention that addresses everyday communication situations.

Aims

To determine how cognitively and socially demanding conditions affect micro- and macrolinguistic production for people with moderate, mild, or no aphasia during narrative discourse and to compare effects among groups.

Method

Thirty participants with mild (n = 9), moderate (n = 9), or no (n …

Feasibility Of An Abstract Verb Naming Treatment For Aphasia, Dallin J. Bailey, Lisa Bunker, Julie L. Wambaugh

Faculty Publications

Purpose

Verb production impairments in aphasia have important implications for sentence production and communication in general. Verbs with low concreteness may be especially important for certain functional uses, and yet limited data regarding their response to treatment are available. This study was designed to examine a novel behavioral treatment approach to improve low concreteness verb naming in persons with aphasia.

Method

Three persons with nonfluent aphasia participated in a single-subject experimental design research study examining the feasibility of the novel treatment. The treatment was based on approaches that target the verb as the central node of meaning during sentence construction. …

Physiological Arousal, Attentiveness, Emotion, And Word Retrieval In Aphasia: Effects And Relationships, Tyson G. Harmon, Angela Johnson, Vivian Ward, Shawn Nissen

Faculty Publications

Purpose: To (a) compare physiological arousal and attentiveness during a confrontational naming task between participants with aphasia and a control group across four conditions that varied according to emotionality of presented stimuli and (b) explore relationships among physiological arousal, attentiveness, perceived arousal, and naming performance. We hypothesized that participants with aphasia would show lower levels of arousal and attentiveness than control participants and that emotional conditions would lead to increased physiological arousal and attentiveness.

Method: Eight participants with aphasia and 15 control participants completed a confrontational naming task under positive, negative, and neutral conditions and rated their perceived arousal after …

Telling Stories In Noise: The Impact Of Background Noises On Spoken Language For People With Aphasia, Tyson G. Harmon, Brenna Scadden Nelson, Christopher Dromey, Kirsten Dixon Clawson

Faculty Publications

Purpose: Determine how different background noise conditions affect the spoken language of participants with aphasia during a story retell task.

Method: Participants included 11 adults with mild to moderate aphasia and 11 age- and gender-matched controls. Participants retold stories in a silent baseline and five background noise conditions (conversation, monologue, phone call, cocktail, pink noise). Dependent measures of speech acoustics (fundamental frequency, mean intensity), speech fluency (speech rate, disfluent words), and language production (correct information units, lexical errors, lexical diversity, and cohesive utterances) were compared between groups and across conditions.

Results: Background noise resulted in higher fundamental frequency (F_{0 …}

Trumpet Directivity From A Rotating Semicircular Array, Samuel D. Bellows, Joseph E. Avila, Timothy W. Leishman

Directivity

The directivity function of a played musical instrument describes the angular dependence of its acoustic radiation and diffraction about the instrument, musician, and musician’s chair. Directivity influences sound in rehearsal, performance, and recording environments and signals in audio systems. Because high-resolution, spherically comprehensive measurements of played musical instruments have been unavailable in the past, the authors have undertaken research to produce and share such data for studies of musical instruments, simulations of acoustical environments, optimizations of microphone placements, and other applications. The authors acquired the data from repeated chromatic scales produced by a trumpet played at mezzo-forte in an anechoic …

Pattern-Based Target Selection For Treatment Of Irregular Past Tense: A Single-Case Experimental Design For Children With Dld, Kirsten M. Hannig Russell, Amy Wilder, Julie L. Wambaugh

Faculty Publications

Purpose: Many children with developmental language disorder (DLD) demonstrate difficulty inflecting irregular past tense verbs. We evaluated using phonological-based patterns (i.e., schemas) to select targets for treatment of irregular verb inflection for children with DLD. We hypothesized this approach would result in acquisition of treated verbs, generalization to untreated verbs within the same phonological schema, and increased use of correct irregular verbs in naturalistic contexts.

Method: Treatment was provided to three 7-year-old participants with DLD in the context of multiple baseline design across behaviors and participants. Phonological schemas included vowel change, final alveolar, and dual change irregular verbs. Treatment was …

Perceptual Ratings Of Pronunciation For L2 Learners Of English As A Function Of Task Type, Word Position, And Listener Expertise, Shawn L. Nissen, Rachel Kemmey, K. James Hartshorn

Faculty Publications

Abstract Second language (L2) learners of English must learn to pro-duce English phonemes, words, and sentences. These L2learners make many errors when learning English; they may change the place or manner of articulation, insert vowels, or delete consonants. Obstruent sounds, such as fricatives, affricates, and stops, can be especially difficult for L2 learners. This study analyzed native English speakers’ perception of the quality of obstruents produced by native Mandarin Chinese and Korean speakers. Target words containing obstruents had been produced in three different tasks: in a carrier phrase, in a paragraph, and in a spontaneous speechsample. Obstruents were produced in …

Evaluation Of A Complexity-Based Morphosyntactic Treatment For Children With Language Disorders Of Mixed Etiologies, Kirsten M. Russell

Faculty Publications

Language disorder is characterized by difficulty with the comprehension and production of different aspects of language. School-aged children with developmental language disorder (DLD) and school-aged children with Down syndrome (DS) demonstrate similar deficits in the area of morphosyntax, which often creates barriers during social interactions and for academic learning. Although affected children may receive intervention, progress can be slow. Selecting appropriate treatment targets is critical for effective intervention. Traditional approaches for selecting treatment targets are based on developmental readiness (i.e., developmental) or functional need (i.e., remedial). However, intervention utilizing targets selected by these methods produce only modest results, despite a …

Similar Overall Expression, But Different Profiles, Of Autistic Traits, Sensory Processing, And Mental Health Between Young Adult Males And Females, Garrett Cardon

Faculty Publications

Recent trends suggest that autism is more common in females than traditionally held. Additionally, some argue that females express autistic traits differently than males. Dimensional views of autism could shed light on these issues, especially with regards to understudied behavioral areas, such as sensory processing. We examined autistic traits, sensory processing, anxiety, and related behaviors in a large sample of neurotypical young adult males and females (n = 1122; 556 female; ages 19–26). Participants completed an online survey containing questionnaires related to the above.

Uncertainty, Sensory Processing, And Stress In Autistic Children During The Covid-19 Pandemic, Garrett Cardon, Mollie Bradley

Faculty Publications

Background: COVID-19 increased uncertainty for most and was especially disruptive to autistic people and their families, due in part to tendencies toward intolerance for uncertainty across this population. As such, COVID presented a natural experiment of uncertainty and its correlates in autism. Previous reports have shown associations between intolerance of uncertainty, sensory difficulty, and stress. Aims: We investigated changes in sensory difficulties and stress associated with COVID-related increases in uncertainty. Methods and procedures: Primary caregivers of 47 autistic children (ages 6–15) completed online surveys containing questions about demographics, experiences, and supports received during the pandemic. Additionally, caregivers filled out measures …

Teaching Non-Native Sound Contrasts Using Visual Biofeedback, Shawn L. Nissen

Faculty Publications

This demonstration will explain how non-native sound contrasts can be taught to second language (L2) learners using real-time visual biofeedback through an electropalatographic (EPG) sensor. How the EPG sensor is created from a dental mold and is subsequently produced will be shown during the presentation. An explanation of how a student can visualize the contact patterns of their speech and how a tutor might use the various features of the associated software to customize the instruction to an individual speaker will be illustrated during the presentation. Possible limitations, costs, and drawbacks to using the technology will also be discussed.

Intolerance Of Uncertainty, Sensory Processing, And Related Correlates In Autistic Children During The Covid-19 Pandemic, Mollie Bradley

Theses and Dissertations

The COVID-19 pandemic increased uncertainty and anxiety for most and was especially disruptive to autistic people and their families. Autistic children were particularly vulnerable due to their intolerance for increased uncertainty and disruption to their school and therapy support. This study aimed to investigate the effect that increased uncertainty had on autistic children, specifically their sensory behaviors and stress levels and on the stress levels of their primary caregivers. Parents and guardians of 47 autistic children completed an online survey consisting of questions investigating background and demographic information, their experiences during the first six months of the pandemic, information about …

A Comparative Study On The Expository Writing Abilities Of Kindergarten Students With And Without Developmental Language Disorder, Kristine Michelle Dayley Andrus

Theses and Dissertations

State standards require kindergarten students to produce expository writing, but little research has been done regarding their abilities in this area. This study describes expository writing samples of 47 typically developing (TD) kindergarteners and 43 kindergarteners with developmental language disorder (DLD). The Expository Language Measures (ELM) Flow Chart and the Systematic Analysis of Language Transcripts (SALT) software were used to detail the language complexity and text structure features the children in the sample produced. When comparing TD and DLD children's expository written samples, no significant differences in the language and text structure measures were found. It is important to continue …

The Analysis Of Omission And Substitution Errors In Various Language Tasks In Bilingual Children, Macy Whiting

Theses and Dissertations

As the population of Spanish-English bilingual children in the United States steadily grows, the importance of accurately assessing and diagnosing developmental language disorder (DLD) has also grown. Understanding a child's underlying language learning system is critical in this process. Several studies have demonstrated the efficacy of nonword repetition (NWR) tasks in bilingual children across a wide range of development, however there is little information regarding guidelines for interpretation of NWR performance or analyzing error patterns. This study was conducted to address these gaps in the research. A sample of 26 Spanish-English bilingual school aged children (6;0-9;4) were administered English and …
