Reduce Challenging Behaviors And Enhance Functioning In Youth With An Intellectual Disability: A Meta-Analysis Of Behavioral Interventions Using Single Case Design, Brett A. Stone

Graduate Theses and Dissertations

Approximately 1.8% of students in the public school system have an intellectual disability or Autism Spectrum Disorder. These disabilities cause impairment in multiple domains of functioning. If these students also have challenging behaviors, such as noncompliance, aggression, and stereotypies, these behaviors have been found to cause impairment over and beyond those of the core symptoms associated with the disability. Challenging behaviors in youth with developmental disabilities do not typically subside on their own and need intervention. Thankfully, there are evidence-based behavioral interventions for individuals with developmental disabilities to reduce challenging behaviors and increase more functional behaviors including Applied Behavioral ...

Development And Validation Of The Waiting Assessment Interview Tool (Wait) And Evaluation Of Individualized Waiting Durations In Signaled Reinforcement, Claudia Campos Fleitas

Graduate Theses and Dissertations

Indirect assessments are widely used to identify environmental factors that may be manipulated or integrated in the development of direct assessments and behavior interventions for individuals with developmental disabilities. To date, there are no indirect assessments that can be used to evaluate the extent to which children who engage in problem behavior wait to receive reinforcement. However, there are effective behavior interventions to increase waiting. A treatment package consisting of functional communication training (FCT) and schedule thinning (i.e., multiple schedules) has been identified as an effective intervention to increase waiting in children who engage in problem behavior maintained by ...


Effects Of Mild Traumatic Brain Injury On Ethanol Consumption And The Combined Effects On Neuroinflammation, Cognition, And Behavior In Mice, Jessica L. Hoffman Jul 2018

Effects Of Mild Traumatic Brain Injury On Ethanol Consumption And The Combined Effects On Neuroinflammation, Cognition, And Behavior In Mice, Jessica L. Hoffman

Graduate Theses and Dissertations

The relationship between alcohol consumption and traumatic brain injury (TBI) often focuses on alcohol consumption increasing the likelihood of incurring a TBI, rather than alcohol use outcomes after TBI. This focus is in part due to the large numbers of TBI patients visiting emergency rooms notable levels of alcohol in their blood. Additionally, increases in alcohol use disorders following TBI can be predicted by previous history of alcohol use. However, studies have also shown patients without a history of an alcohol use disorder can experience increases in problem drinking after single or multiple TBIs. Due to the diffuse impact of ...

Parent-Child Interaction Therapy For Children With Autism Spectrum Disorder: An Analysis Of Behavioral Patterns And Treatment Barriers, Kimberly A. Knap Jun 2018

Parent-Child Interaction Therapy For Children With Autism Spectrum Disorder: An Analysis Of Behavioral Patterns And Treatment Barriers, Kimberly A. Knap

Graduate Theses and Dissertations

Children diagnosed with autism spectrum disorder (ASD) experience difficulties with social communication and restrictive, repetitive, and stereotyped behavior patterns that place them at an increased risk for developing challenging behaviors that warrant early intervention (American Psychiatric Association, 2013). These problems are unlikely to decrease without intervention. Research indicates that parents’ involvement in behaviorally based interventions improves the functioning of children with ASD (Horner, Carr, Strain, Todd, & Reid, 2002). . Parent-Child Interaction Therapy (Eyberg & Funderburk, 2011) is an empirically supported intervention for young children with disruptive behaviors. PCIT shares similarities with numerous proven ASD treatments including caregiver involvement, structure and predictable schedule ...


Early Literacy Abilities In Spanish-English Emergent Bilingual Children From Varied Dialectal Backgrounds, Antonietta Mastrota Jun 2018

Early Literacy Abilities In Spanish-English Emergent Bilingual Children From Varied Dialectal Backgrounds, Antonietta Mastrota

Graduate Theses and Dissertations

The Hispanic population within the United States has grown to a considerable amount. The state of Florida’s population is 25% Hispanic, with projected estimates of this population continuing to grow in the coming years (Ortman & Shin, 2011). Statistics show that 28.3% of the state’s population, over the age of five, speak a language other than English at home. With this considerable number of Spanish-speakers comes the responsibility to adjust certain educational practices to best meet their needs. Literacy is an essential part of learning, and therefore assessing early literacy is an essential part to any child’s academic development.

Phonological awareness is the ability to manipulate and identify the phonological segments of a word (Blachman, Tangel, Ball, Black & Mcgraw, 1999). It is a strong predictor for early literacy abilities (Bradley & Bryant, 1983, Kozminsky & Kozminsky, 1995, Vandervelden & Siegel 1997). This relationship between phonological awareness and early literacy exists within the English language, and also within many other alphabetic languages such as Spanish (Anthony, Williams, McDonald, Corbitt-Shindler, Carlson, & Francis, 2006). Therefore, phonological awareness shares an important relationship to early literacy abilities for both English and Spanish speakers.

There are many morphological, phonological, syntactical, and lexical subtleties that exist between varied dialects of the Spanish language. Vocabulary and lexicon use has been shown to positively influence phonological awareness skills in young children. Dialectical classifications of the participants were determined through use of different dialect specific vocabulary word list in the Linguistic and Cultural Background Survey. This study sought to evaluate whether dialectical differences among young Spanish-English bilinguals were associated with performance on measures of phonological awareness and reading.

Twelve participants (children ages 3.17 years to 7.5 years and their parents participated in the study. Children completed a short form of the dynamic assessment of phonological awareness in Spanish (Loreti, 2015), the Letter-Word Identification of the Woodcock-Muñoz Language Survey-Revised (WMLS-R; Woodcock et al., 2005), the Elision, Rapid Automatic Naming, and Letter Name/Letter Sound subtests from the Test of Phonological Sensitivity in Spanish (TOPSS; Brea et al., 2003) and the Preschool Language Scales, Fifth Edition Spanish Screening Test (PLS-5; Zimmerman et al., 2011). Parents completed a Linguistic and Cultural Background Survey designed to identify potential dialectical differences among the children.

Results from the Linguistic ...


Ability Of The Iso Predicted Heat Strain Method To Predict A Limiting Heat Stress Exposure, Edgar Prieto Jun 2018

Ability Of The Iso Predicted Heat Strain Method To Predict A Limiting Heat Stress Exposure, Edgar Prieto

Graduate Theses and Dissertations

Heat stress is one of many physical agents to which thousands of workers are under constant exposure. Oftentimes it is necessary to work above the WBGT-based heat stress exposure limits. It is therefore important to consider alternative measures that include an exposure time limit to manage the heat stress. Predicted Heat Strain (PHS) (ISO7933) is one of those alternatives. PHS uses both personal factors like height and weight and job factors of environment, metabolic rate and clothing. The purpose of this project is to determine whether the PHS is an adequate method to predict short term exposure limits.

Validity Of A Dynamic Spanish Assessment Of Phonological Awareness In Emergent Bilingual Children, Kelsey R. Wyman Chin Jun 2018

Validity Of A Dynamic Spanish Assessment Of Phonological Awareness In Emergent Bilingual Children, Kelsey R. Wyman Chin

Graduate Theses and Dissertations

Within the current decade, the number of Hispanic students has doubled so that about 16% of the total student population within the United States are Spanish-speakers (U.S. Census Bureau, 2017). With this growing population comes a responsibility to understand and implement best practices for educating these students. Because literacy is a building-block for learning, one integral part of this responsibility consists of developing valid and reliable means of assessing pre-reading skills that are predictive of later reading abilities (Lonigan, Burgess, & Anthony, 2000; Wagner, Torgesen, & Rashotte, 1994).

English-language learning children are being identified for having reading difficulties and disabilities two to three years later than their English-proficient peers (Chu & Flores, 2011). As a population, they are also overly misidentified as having reading difficulties/disabilities and being unnecessarily placed into a special education system (McCardle, Mele-McCarthy, Cutting, Leos, & D’Emilio, 2005b; Sanatullova Allison & Robinson-Young, 2016). Per a nationwide survey of Speech-Language Pathologists, one large contributing factor for this dilemma is the lack of appropriate assessment instruments (Roseberry-McKibbin, Brice, & O’Hanlon, 2005).

Phonological awareness is the ability to focus on and manipulate units of spoken language (words, syllables, onsets, rimes, and/or phonemes). It is one of the most significant predictors of later reading abilities. A large body of evidence provides support for this within the English language but also within other alphabetic languages, such as Spanish (e.g. Carillo, 1994; Durgunoglu, Nagy, Hancin-Bhatt, 1993; Schneider, Kuspert, Roth, Vise, & Marx, 1997). Thus, assessments of phonological awareness have been shown to be reliable measures that predict later reading abilities in Spanish-speaking children and English-proficient children alike (Farver, Nakamoto, & Lonigan, 2007).

There are many standardized assessments available to test phonological awareness as an emergent literacy skill in English. In congruence with the previously mentioned nationwide survey, Spanish assessments of phonological awareness are less abundant. Additionally, these tests tend to be expensive, time-consuming to give, and require training of the administrator. These tests are static in nature and regularly require the child to comprehend complex administrative instructions which is often problematic for children with limited language skills in Spanish and/or English (Barker, Bridges, & Saunders, 2014).

The current study aims to build upon existing data regarding development of the DAPA-S by evaluating the validity of a shorter version of the DAPA-S (the DAPA-S Short Form) with children from Spanish-speaking backgrounds. The DAPA-S Short form was designed with the purpose of retaining all the test items of the full version but with an altered structure which allows for significantly shorter administration time. The DAPA-S and the shorter version were both designed as Spanish dynamic assessments of phonological awareness which are computerized, have simple instructions, provide information about a child’s ability to learn from instruction, and do not require speech responses.

The twelve participants that were involved in this study were given the DAPA-S Short Form as well as other assessments related to phonological awareness or emergent reading. Three of those participants did not complete the study due to poor attendance or behavioral challenges. Therefore, this study reports on nine participants who completed the full assessment battery.

To investigate concurrent validity, correlational analysis was performed with the DAPA-S Short Form scores and scores from a measure of phonological awareness, the Test of Phonological Sensitivity in Spanish (TOPSS; Brea, Silliman, Bahr, & Bryant, 2003). The Elision, Rapid Automatic Naming, and Letter Name/ Letter Sound subtests from the TOPSS were administered. No significant correlations were observed between either subtest from the DAPA-S Short Form and any of the subtests from the TOPSS (r = .49 for Elision, r = .36 for RAN, r = .43 for Letter Name/Letter Sound subtests). Therefore, concurrent validity was not established as measured in this study.

To investigate convergent validity, correlational analysis was performed with the DAPA-S Short Form subtests and the scores from a measure of Spanish emergent reading skills, the Letter-word Identification (LWID) subtest from the Woodcock-Muñoz Language Survey – Revised (WMLS-R; Woodcock, Muñoz – Sandoval, Ruef ...

Articulatory Patterns In Children Who Use Cochlear Implants: An Ultrasound Measure Of Velar Stop Production In Bilingual Speakers, Katherine Javier Jun 2018

Articulatory Patterns In Children Who Use Cochlear Implants: An Ultrasound Measure Of Velar Stop Production In Bilingual Speakers, Katherine Javier

Graduate Theses and Dissertations

Coarticulation occurs in running speech when one speech sound or phoneme overlaps with another. It can be considered a result of the way we sequence and organize our articulators to efficiently produce consecutive consonants and vowels in fluent speech. Previous research has suggested that measures of coarticulation can provide insight into the maturity of the motor speech planning system (Barbier, Perrier, Ménard, Payan, Tiede, & Perkell, 2013; Zharkova & Hewlett, 2009; Zharkova, Hewlett, & Hardcastle, 2011). Speech stability has also been suggested as an indicator of motor speech maturity in previous research using ultrasound imaging of velar-vowel targets (Frisch, Maxfield, & Belmont, 2016). This study extends research by Frisch, Maxfield, & Belmont (2016) to investigate patterns of velar-vowel coarticulation and speech stability in bilingual children who wear cochlear implants.

Ultrasound and acoustic data were recorded from one English-Spanish bilingual participant (P1) who wears bilateral cochlear implants, one English-Spanish bilingual control child (P2) with no hearing impairment, and one English-Spanish bilingual adult speaker. Measures of velar-vowel coarticulation and speech stability across three productions of English and Spanish words were recorded and analyzed following procedures of Wodzinski and Frisch (2006). The participants were asked to produce three repetitions of fifteen English and fifteen Spanish target words starting with a /k/+ vowel sequence. Ultrasound imaging was used to record and trace tongue movement at the point of maximum velar closure. Data was compared between English and Spanish words, across participants, and between repetitions of the same word.

In comparing English and Spanish words, child participants (P1 and P2) demonstrated increased coarticulation during Spanish productions. All participants showed decreased stability in Spanish productions when compared to English. Adult participant (P3) showed greater overall stability in productions and consistent coarticulation across both languages. Measures of coarticulation and overall stability were relatively equal across P1 and P2, while P3 showed greater and more stable coarticulation across both languages. Preliminary results support findings in previous research suggesting that anticipatory coarticulation and speech stability could be used as an index for assessing speech motor planning in bilingual and clinical populations (Barbier, Perrier, Ménard, Payan, Tiede, & Perkell, 2013; Frisch, Allen, Betancourt, & Maxfield, 2016; Frisch, Maxfield, & Belmont, 2016; Frisch & Wodzinski, 2014; Zharkova & Hewlett, 2009; Zharkova, Hewlett, & Hardcastle, 2011). Results additionally indicate that a young cochlear implant user who receives early intervention and is learning two languages can develop commensurate motor ...

Relationship Between Vocal Fatigue And Physical/Psychological Factors In Prospective Vocal Professionals, Camille C. Gray Jun 2018

Relationship Between Vocal Fatigue And Physical/Psychological Factors In Prospective Vocal Professionals, Camille C. Gray

Graduate Theses and Dissertations

Background: To date, research has primarily focused on the subjective and objective measurement of vocal fatigue in professional voice users such as teachers and singers. However, these studies have not examined the effects of psychosocial factors (e.g., lack of sleep, emotional distress) leading to vocal fatigue in depth. Much like the professional voice users, students seeking to be professional voice users may face several psychosocial difficulties, may also experience similar vocal demands, and may develop vocal fatigue.

Goal: The purpose of this study is to identify the relationship between psychosocial factors and vocal fatigue in students majoring in Communication ...
