The Effects Of Bilingualism On Auditory Selective Attention In Normal-Hearing Adults, Francisco Fernandez

Open Access Theses & Dissertations

Bilingual speakers have been shown to be more adept than monolingual speakers at actively blocking useless information in the visual modalities. This advantage should be observed in both the visual and the auditory modalities using tasks of inhibitory control. However, very little is known regarding how bilingualism influences inhibitory control in the perception of auditory information. By using an auditory test of inhibition, such as the utilization of a Dichotic Listening task, bilinguals are expected to display an increased measure of cognitive ability.

Does Knowledge Of Concussion Symptoms Influence An Athlete's Self-Report Of A History Of Concussion Across Gender And Age?, Kara Ashlan Greco

Open Access Theses & Dissertations

Background: The incidence of sport-related concussion is debatable. While the Centers for Disease Control and Prevention report an extrapolated incidence of 1.6 to 3.2 million recreational/sports-related traumatic brain injuries a year, the suspicion is that the incidence is much higher (CDC, 2014). An important consideration in determining the incidence involves whether an athleteâ??s knowledge of what a concussion is influences their self-report of prior concussions.

Purpose: The purpose of this study is to replicate and extend Pfirman (2015) in determining whether providing information about concussion will increase the self-report of a history of concussion. Furthermore, this study investigates whether there …

Nature Of The Verbal Fluency Task In Concussed Athletes, Paulina Mejia

Open Access Theses & Dissertations

Background: Verbal fluency is a common test used to assess naming in individuals with brain injury. Troyer (1997) reported that naming components such as phonemic clusters and categorical switching might be more sensitive to the presence of brain injury than a reduction in the total number of words that is commonly used as a measure. Phonemic task refers to the F-A-S naming task while the semantic task refers to the animal naming task because of the frequent production of the phonemic cluster on the F-A-S and semantic clusters on the animal naming task (Troyer, 1997).

Purpose: The purpose of this …

An Investigation Of Motor Speech And Motor Limb Movements Following A Sport-Related Concussion-An Extension Study, Linda Phan

Open Access Theses & Dissertations

Background: Minimal research is available regarding the effects on motor speech and motor limb movements following a sport-related concussion (SRC). A sensitive measure is necessary to detect subtle deficits in motor speech, as it may provide diagnostic insight involving return-to- play decisions.

Purpose: This research aimed at replicating and extending a previous research study, Hewitt (2015), conducted at the University of Texas at El Paso. The Hewitt (2015) study examined motor speech tasks and motor limb tasks which included the following: oral diadochokinetics (DDK): sequential motion rate (SMR)(i.e. /puh-tuh-kuh/) and alternating motion rate (AMR) (i.e. /puhpuhpuh/, /tuhtuhtuh/, /kuhkuhkuh/); speech rate …

The Effect Of A Fluent Signing Narrator On Children's Behavior During Technology-Enhanced Shared Reading With Children With Hearing Loss And Their Parents, Gabriela Itzel Rodriguez

Open Access Theses & Dissertations

Shared reading plays an essential role in the language and literacy development of children who are at risk of future problems in those areas. Children with hearing loss (CHL) are a group who usually experience limited and poor quality activities that foster literacy development such as shared reading (SR). Researchers examining high quality interactions have rated child behaviors, primarily attention and initiation, during shared reading and play based activities finding positive correlations between these behaviors and the overall development in typically developing children as well as in children with other impairments such as Autism Spectrum Disorder and Down syndrome (Kim …

The Spanish-English Bilingual: A Cross-Classfication Comparison Of Maze Use In Children, Jessica Valles

Open Access Theses & Dissertations

With the continual increase of bilingual individuals in the United States, there is a critical need for research that can appropriately identify unique characteristics of language production for these individuals. In particular, maze use, or errors in production have been identified as a characteristic of language that typically occurs more in bilinguals' speech production than in monolingual productions. Research comparing bilingual maze use in individuals who are typically developing with bilingual maze use individuals who are language impaired is limited. To compare these bilingual children with language impairment with to their typically developing peers, children were paired by age, grade, …

The Effects Of Sign On Speech Segmentation In Infants, Alma Rosa Acosta

Open Access Theses & Dissertations

Introduction: The ability to extract words from fluent speech (speech segmentation), perhaps one of the greatest obscure achievements for the purpose of learning language, is dependent upon imperceptible endeavors. Remarkably, infants are active participants from the moment they are born, using auditory and visual information to assist them segmenting speech. As motivated parents attempt to use baby sign to bridge communication gaps, visual information in the form of baby sign may benefit children in extracting words from speech. To examine the effects of baby sign on speech segmentation, a systematic replication of the Hollich et al. (2005) study, a within-subject …

The Effects Of Baby Sign On Child Development, Joanna Scott

Open Access Theses & Dissertations

Introduction: Although the popular media supports the use of baby sign for enhanced developmental outcomes of children, empirical research verifying the actual effects of baby sign on the areas of communicative, cognitive, social, and physical development, is limited. Advocates of baby sign suggest pre-lingual symbolic communication may result in accelerated development whereas critics claim definitive conclusions cannot be drawn because of flawed methodology in the research. Purpose: The purpose of the present study was to explore whether baby sign has an impact on the developmental growth of children. Methods: Using a between groups research design, assessment data were obtained from …

Does Knowledge Of Concussion Symptoms Influence An Athlete's Self-Report Of History Of Concussion Across Age Groups?, John Pfirman

Open Access Theses & Dissertations

Purpose: The purpose of this study was to determine if an athlete's self-report of a history of concussion would increase if they are provided with information about concussions.

Study Design: This study used a group design pre-test information group and a post-test information group matched for age.

Methods: Prior to cognitive testing, the athletes were divided into an experimental and control group. The experimental group received information about concussions before taking the cognitive test. The control group did not receive concussion information before cognitive testing. Both groups completed a questionnaire following testing that asked: "Based on your experience here today, …

The Impact Of Baby Sign Training On Stress Levels Of Daycare Providers, Grisel Julieta Rodriguez

Open Access Theses & Dissertations

Proponents of baby sign claim improvements in child-caregiver interactions and reductions in parental stress as benefits of implementing baby sign. Due to research contradicting the claims, and to the rise in daycare attendance, the current study investigated the effects of a baby sign workshop on the stress perception of daycare providers. A pre-test post-test between groups design with 20 participants was conducted using the Perceived Stress Scale (PSS10) and a workshop-specific descriptive survey as measures. The difference between the post-test stress levels of experimental and control groups approached significance, as did the differences between pre-test and post-test results for the …

Event Related Potentials In A Two Stimuli Auditory Oddball Task In Concussed College Athletes: A Linguistic Component Replication Study, Christopher Anthony Roosmalen

Open Access Theses & Dissertations

Concussions affect an estimated 1.6 to 3.8 million individuals annually and can result in persistent symptoms and cognitive impairments in attention and memory. Concussions are a rising health concern especially in concussion management. Event Related Potentials (ERP) may more accurately assess cognitive recovery making better return to play decisions. In 2013, Sanchez found no significant difference between concussed athletes and non-concussed individuals in the in amplitude of the P300 ERP component using an auditory oddball task consisting of 2 different consonant, vowel (CV) syllables. Because participants were instructed to maintain a mental and verbal count of the target stimuli, a …

The Contribution Of Mild Traumatic Brain Injury/Concussion To The Development Of Post-Traumatic Stress Disorder Symptoms, Kylie Lauren Marshall

Open Access Theses & Dissertations

A controversial issue is whether TBI is a necessary precursor to the development of PTSD symptoms, or if the two variables are mutually exclusive. Recent rodent-models reveal that a stressful environment cannot cause PTSD symptoms directly without TBI, yet it is unknown if PTSD symptoms can develop following a TBI. This study provides a potential analogue to study this relationship by evaluating the effects of sports-related concussion. Purpose: This study investigated two questions, 1) Is there a significant difference in the frequency of PTSD symptoms reported by athletes at baseline (BL) testing and post-concussion (PC) testing over time? 2) Is …

The determination of prognosis following sports-related concussion can be used to facilitate return-to-play and academic decision making in concussion management.

Purpose: The purpose of this study was to replicate and extend previous research in determining the accuracy, sensitivity, specificity, and predictive value of computerized neurocognitive test scores and symptom cluster scores in predicting protracted recovery following sports-related concussion.

Study Design: Systematic replication, Cohort study (prognosis)

Methods: 30 concussed collegiate athletes were followed …

A Comparison Of Maze Frequency And Type Across Language And Speaker: A Look At English And Spanish Narrative Retells, Melissa Silver

Open Access Theses & Dissertations

Background: Mazes, as they are referred to in the language literature, are disfluencies that do not add meaning to an utterance including filled pauses, whole word revisions, part word revisions, part word repetitions and whole word repetitions. Extensive research has been conducted on mazes in monolingual and bilingual children, yet the research has not been extended to adults' narrative retell production.

Aims: The current study analyzes monolingual English, monolingual Spanish, and bilingual English and Spanish narrative retells to compare the percent of maze use and type of maze use amongst groups.

Methods & Procedures: The narrative retells of thirty-nine bilingual …

Open Access Theses & Dissertations

Introduction: Baby sign has gained the attention of many researchers and parents. Relatively little is known about the use of baby sign and the impact it has on the development of children. As the use of baby sign increases in popularity, research studies have had limited and inconsistent results regarding its influence. Purpose: The purpose of this study is to measure the effects of baby sign training on the overall development of normally hearing children while improving on the limitations of current studies (between group study). Methods: Participants in the study included 22 children, ages 6 months to 2 years; …

A Comparative Assessment Of Electrophysiological And Behavioral Performance In Individuals With Aphasia Responding To Spoken And Written Sentence Length Commands, Sha-Renae Alexander

Open Access Theses & Dissertations

The aim of this study is to investigate whether deficits in processing affect auditory and reading comprehension in the same manner. This study compared the behavioral and electrophysiologic performance of four individuals with aphasia and four participants with no brain damage responding to spoken and written sentence length commands using a modified version of the Revised Token Test (McNeil & Prescott, 1978). Electrophysiological responses were recorded from the scalp using event related potentials (ERP). The latency and amplitude of the N400 ERP component were measured and analyzed. Behavioral reaction times and correct responses were collected and examined. Performance differences between …

Processing Of Language Switches In Bilingual Individuals With Aphasia: An Event-Related Potential Comparison, Lizette Rodarte

Open Access Theses & Dissertations

Switching between languages, or code-switching, is a common phenomenon in bilingual individuals. In proficient bilinguals, these switches are done with ease and are used for many purposes. Contrary to popular belief, these switches are rule-governed and follow grammatical structure. Bilingual individuals diagnosed with aphasia present with difficulty processing languages and these language switches. With the increase in bilingual individuals, it is likely that the speech-language pathology community will see an increase of bilingual individuals with aphasia on their caseload. For this reason, the purpose of this study is to increase our understanding of the neural processes involved in processing of …

The Impact Of Accented English On Speech Comprehension, Benigno Valles

Open Access Theses & Dissertations

ABSTRACT

In the context of shifting demographics in the United States and with an increasing multicultural workforce, the verbal exchange of information is vital especially between health care providers and patients. Although English is the official language in the United States, many individuals from different national origins speak English with some degree of accent. Before we can address health care provider/patient communication, it is necessary to investigate the potential impact of accented English on speech comprehension and its implications on basic communicative interactions. The verbal exchange of information between health care providers and patients is important in diagnostics, treatment, patient …

The Effects Of Cognates On Receptive And Expressive Language Among Typically Developing Preschool Second Language-Learners, Jesica B. Zavala De Guerrero

Open Access Theses & Dissertations

This exploratory study considers the facilitating effects of cognates across language of intervention, seeking to assess potential cross-language generalizations among typically developing preschool bilinguals. Nine bilingual, English-Spanish speakers of preschool age were assigned to one of three experimental groups (an English only group, a Spanish only group, and a bilingual group) or to a control condition. Children in the experimental groups were introduced to a vocabulary intervention that incorporated cognates and non-cognates. Analysis of data suggests the absence of a cognate advantage among preschool age children; furthermore limiting any possible cross-language generalizations. It is plausible to suspect that age may …

Services And Information Provided To Mothers In El Paso/Juarez Region, Christina Y. Perez

Open Access Theses & Dissertations

It is estimated that the Latino population will be the majority of the population by 2050 in the United States. There is research supporting the notion that the Latino population is under-served and under-diagnosed regarding physical and mental illnesses. Appropriately informed professionals and parents are the first step to reducing the number of under-diagnosed children that do not receive the treatment they require. This survey was conducted to determine what information Latino mothers from low socio-economic backgrounds possess concerning the developmental milestones of their children and the services available to them. Fifty mothers responded to the survey. Results revealed that …

Potential Influences Of Compliance For Short-Term Recovery From Sports-Related Concussion, Erin R. Ewing

Open Access Theses & Dissertations

Currently, treatment of sports-related concussion dictates the prescription of physical and cognitive rest to allow the injured brain to recover and for concussion-related symptoms to subside. However, clinicians who prescribe rest are often met with resistance from athletes who do not recognize its therapeutic value in the recovery process. Research has shown that athletes often fail to comply with rest recommendations, resulting in protracted recovery and the persistence of symptoms. Method: This study employed a three-group pretest-posttest experimental design to compare the effects of three different concussion management protocols. Participants were recently concussed athletes ages 18-25 seen in the UTEP …

A Pilot Study: Examining The Microstructural And Macrostructural Narrative Measures In Bilingual Preschool Aged Children, Caroline Esparza

Open Access Theses & Dissertations

Purpose: Research has identified narratives as accurate and reliable predictors of language skills, yet little is documented on the microstructural and macrostructural narrative production of preschool aged bilingual children. This pilot study examined the microstructure and macrostructure elements of narratives in these children to provide preliminary data for further research.

Method: This study examined the narrative skills of 11 bilingual children between the ages of 3 and 4. Narrative retells in Spanish were elicited and were analyzed for the microstructural measures of lexical diversity (NDW) and productivity (TNW and MLU) measures and for the their macrostructural Narrative Scoring Scheme (NSS) …

Nonword Repetition Performance Patterns In English - Spanish Bilingual Adults And English And Spanish Monolingual Adults, Nadia Arriazola Flores

Open Access Theses & Dissertations

Nonword repetition (NWR) is known to be a less biased measure for assessing language abilities of culturally and linguistically diverse (CLD) children (Dollaghan & Campbell, 1998). NWR is used to examine phonological short-term memory mechanisms (also called working memory), because the tasks require the capability to discriminate, store, remember and reproduce phonological sequences (Baddeley, 1989; Braddeley 1974). The purpose of this study was to collect normative data on the NWR performance of bilingual and monolingual adults. This may contribute to the interpretation of performance in bilingual children by providing the standard of adult-like performance. This study examined the performance patterns …

Evaluation Of Language Of Intervention On Expressive-Receptive Lexical Skills For Preschool Bilingual Children, Blanca Estela Cisneros

Open Access Theses & Dissertations

The purpose of the study was to evaluate the expressive-receptive lexical skills gained in bilingual preschool children for both their native language (L1) and second language (L2) when provided a bilingual vocabulary intervention and compared to contrasting monolingual and controlled conditions. This group study assessed four treatment conditions: monolingual English intervention, monolingual Spanish intervention, bilingual English-Spanish intervention, and a controlled intervention condition receiving math instruction. English and Spanish expressive and receptive lexical skills were the dependent variables measured at pretest and posttest. After a brief 4 week intervention block, the bilingual group achieved greater gains in Spanish expressive lexical skills …

Examining Articulatory Kinematics Using Diadochokinesis In Concussed And Non-Concussed Individuals, Lindsay Deann Dolan

Open Access Theses & Dissertations

ABSTRACT

Cognitive and communicative deficits associated with traumatic brain injury are an active area of research. However, no research to date has reported on the functionality of motor speech following a concussion. A common tool used to evaluate the motor speech status of potentially impaired individuals is the measurement of the diadochokinetic speech rate. The purpose of this study is to investigate diadochokinetic speech rates in individuals who experience a sports-related concussion. Determining the nature and extent of motor speech involvement post concussion will contribute to the diagnosis, prognosis, and management of recovery. The present investigation will determine; (i) if …

Over the last few decades the United States has seen a heavy increase in the incidences of Autism Spectrum Disorder. Also increasing in the United States is the increase in multicultural and multilingual groups. Although both of these populations are increasing there is very limited information regarding the language abilities of bilingual individuals with Autism Spectrum Disorder, the language used for intervention, and those servicing them. A survey was developed to gather information regarding the current practice trends used by Speech-Language clinicians with bilingual children with ASD. The study was conducted in El Paso, Texas a city located on the …

Benefits Of Baby Sign On Cognitive Development In Infants, Clarissa Navedo

Open Access Theses & Dissertations

Research in the area of baby sign language has increased dramatically over the past several years, however there is still a lack of research regarding baby signs effects on typical infant development, specifically in the area of cognition. The hypothesis of this study was that instruction of baby sign would be correlated with a significant increase in the development of cognition and language acquisition for infant participants. This study provided a five-week instructional course on baby sign for parents/caregivers to implement with their typically developing infants (n=11). The course provided instruction of baby signs, methods of implementation and encouragement to …

Event Related Potential Changes In A Two-Stimulus Auditory Oddball Task In Concussed College Athletes: A Linguistic Component, Paola G. Sanchez

Open Access Theses & Dissertations

"Return to Play" decisions are done based on cognitive-communicative testing and clinical assessments; concussed athletes may benefit from electrophysiological testing for a more accurate representation of their recovery. The purpose of this study is to investigate the electrophysiological performance post-concussion analyzing the attentional differences using the traditional "oddball" paradigm with a CV linguistic component. Participants for this study were 6 male college athletes with a history of concussion and 10 participants with no history of concussion (controls). Athletes were evaluated using event-related potentials (ERPs) that were recorded during a consonant-vowel (CV) auditory oddball task. Both the P300a and P300b components …
