Early Behavioral And Physiological Markers Of Social Anxiety In Fragile X Syndrome, Conner J. Black Oct 2019

Early Behavioral And Physiological Markers Of Social Anxiety In Fragile X Syndrome, Conner J. Black

Theses and Dissertations

Background: Social Anxiety is diagnosed in approximately 10% of neurotypical children. If left untreated, negative outcomes are highly prevalent later in life. Thus, understanding the earliest features of social anxiety can help to mitigate detrimental outcomes. Fragile X Syndrome, which has a high prevalence of social anxiety, is a genetic syndrome which creates a unique opportunity to study the earliest predictors of social anxiety before formal diagnosis. Fragile X Syndrome presents with intellectual disability and an increased prevalence of maladaptive behaviors. The current study utilized a bio-behavioral approach to study the earliest marker of social anxiety in 12- month-old infants …


A Foundation For Understanding The Neurocognitive Processes That Underlie Mathematics Performance In Children, Christopher Anzalone Oct 2019

A Foundation For Understanding The Neurocognitive Processes That Underlie Mathematics Performance In Children, Christopher Anzalone

Theses and Dissertations

The current study investigated the prognostic utility of resting state EEG coherence in the prediction of standardized mathematics scores. Quantitative EEG analyses were performed for 60 school-aged children (ages 7 to 12 years) with and without math learning disabilities (MLD). Analyses assessing intrahemispheric coherence at rest were performed across the entire sample and several coherence networks were extracted.

Specifically, networks that included Brodmann area 40 (BA 40) -- a region of the brain heavily involved in the cognitive processes responsible for mathematics performance (Anderson, Betts, Ferris, & Fincham, 2011; Cohen, Dehaene, Chochon, Lehericy, & Naccache, 2000; Kroger, Nystrom, Cohen, & …


The Effects Of Autism Symptom Severity And Social Anxiety On Pragmatic Language In Young Adult Males With Fragile X Syndrome, Sara Mcgrath Matherly Jul 2019

The Effects Of Autism Symptom Severity And Social Anxiety On Pragmatic Language In Young Adult Males With Fragile X Syndrome, Sara Mcgrath Matherly

Theses and Dissertations

Pragmatic, or social, language skills play a pivotal role in abilities that facilitate interpersonal relationships and independence, particularly in adulthood. Pragmatic language deficits are considered a core trait of males with fragile X syndrome (FXS); however, mechanisms that influence these abilities are not well known. This research is also limited by a lack of valid assessments that adequately capture pragmatic language skills. The present dissertation is the first to examine pragmatic language skills and mechanisms that influence these abilities using a novel, dynamic language assessment, the Yale in vivo Pragmatic Protocol (YiPP) in young adult males with FXS. Results revealed …


Investigating The Construct Validity Of Sluggish Cognitive Tempo In Children, Kristin L. Roberts Apr 2019

Investigating The Construct Validity Of Sluggish Cognitive Tempo In Children, Kristin L. Roberts

Theses and Dissertations

The term Sluggish Cognitive Tempo (SCT) refers to attention difficulties that are characterized by a constellation of symptoms ranging from excessive daydreaming to drowsiness, sluggishness, and lethargy. Although several SCT scales have been developed in recent years, researchers have yet to agree upon an ideal set of symptoms. In addition, it remains unclear whether SCT consists of a single dimension or if it is a multidimensional construct. The first aim of this study was to extend research related to SCT symptomatology and measurement by conducting a comprehensive investigation of SCT symptoms. A 25-item scale was developed to include each of …


Social Support: Who And What Types Matter For Early Adolescents’ Life Satisfaction, Kimberly G. Sitter Apr 2019

Social Support: Who And What Types Matter For Early Adolescents’ Life Satisfaction, Kimberly G. Sitter

Theses and Dissertations

Trends in current psychological research suggest an increasing interest in indicators of well-being in youth, such as life satisfaction (LS). Studies indicate a strong association between LS and social support from different sources within an early adolescent’s social network. However, the unique contributions of specific types of supportive behaviors (within sources of social support) as they relate to development of early adolescent global LS have been largely overlooked. The current study sought to examine the unique contributions of social support types (emotional, appraisal, informational, instrumental) within three sources of support (parent, teacher, peer) to global LS in a sample of …


Integration Of Theory And Feasibility In Learning Disability Identification: Examining Criteria Effects In The Integrated Assessment And Intervention Model, Allison Stafford Oct 2018

Integration Of Theory And Feasibility In Learning Disability Identification: Examining Criteria Effects In The Integrated Assessment And Intervention Model, Allison Stafford

Theses and Dissertations

The accurate identification of learning disabilities is critical for applied settings as well as for research purposes. Currently, there are multiple methods of learning disability (LD) identification utilized by practitioners, including: IQ/achievement discrepancy, response to intervention, and patterns of strengths and weakness (Hale & Fiorello, 2004). Despite the use of these methods, there is a lack of research on the validity and the rates of Learning Disability identification associated with these methods. Additionally, the use of different methods creates potential differences in the base rates of students identified as having a learning disability. Further, the identification of learning disabilities needs …


Emotion Regulation And Life Satisfaction Of Early Adolescents In The Face Of Stressful Life Events, Zi Jia Ng Jan 2018

Emotion Regulation And Life Satisfaction Of Early Adolescents In The Face Of Stressful Life Events, Zi Jia Ng

Theses and Dissertations

In line with calls to define mental health as more than the mere absence of psychopathology, and based on the restorative model of well-being (Lent, 2004), this dissertation sought to elucidate the relationship between stressful life events and life satisfaction by exploring the mediating role of emotion regulation. Using a full Structural Equation Modeling (SEM) approach, this dissertation first determined the factor structure of the measurement model then evaluated the path analysis of the structural model. The first study examined the factor analytic structure and measurement invariance of the Brief Multidimensional Students’ Life Satisfaction Scale (BMSLSS). Results supported the one-factor …


Prevalence And Predictors Of Anxiety Disorders In Adolescent And Adult Males With Autism Spectrum Disorder And Fragile X Syndrome, Jordan Ezell Jan 2018

Prevalence And Predictors Of Anxiety Disorders In Adolescent And Adult Males With Autism Spectrum Disorder And Fragile X Syndrome, Jordan Ezell

Theses and Dissertations

disorders are the most prevalent disorders in children and adolescents, affecting approximately 15-20% of individuals under the age of 18 (Salum et al, 2013). Clinical subgroups, like autism spectrum disorder (ASD) and fragile X syndrome (FXS), have an elevated risk of a co-occurring anxiety disorder. Despite the elevated risk of anxiety in these groups, few research studies have investigated the rates and predictors of anxiety disorders in adolescents with these ASD and FXS. In the current study, participants included males with FXS (n=31) or ASD (n=20) aged 16 to 24. Measures included the Children’s Interview for Psychiatric Symptoms-Parent Version (P-ChIPS), …


Life Satisfaction In Adolescents With High-Functioning Autism Spectrum Disorder, Kathleen Blackburn Franke Jan 2018

Life Satisfaction In Adolescents With High-Functioning Autism Spectrum Disorder, Kathleen Blackburn Franke

Theses and Dissertations

The present study was informed by the Emerging Disability Paradigm, which emphasizes the importance of research regarding positive experiences, personality, and social relationships for individuals with disabilities (Schalock, 2004). The purpose of this study was to provide preliminary evidence regarding the reliability and validity of measures of self-reported psychosocial assets and life satisfaction (LS) for adolescents with high-functioning autism spectrum disorder (HFA). Additional purposes included identifying the overall levels of general and domain-specific LS within adolescents with HFA, comparing these levels to those of a sample of typically developing adolescents, and describing the relation between psychosocial assets and LS for …


Examining The Factor Structure, Concurrent Validity, And Predictive Validity Of The Social Motivational Orientations In Sport Scale (Smoss) In An Early Adolescent Sample, Alex M. Roberts Jan 2018

Examining The Factor Structure, Concurrent Validity, And Predictive Validity Of The Social Motivational Orientations In Sport Scale (Smoss) In An Early Adolescent Sample, Alex M. Roberts

Theses and Dissertations

Research demonstrates that youth are motivated to initiate and continue participation in sport for social reasons. Allen (2003, 2005) developed the Social Motivational Orientations in Sport Scale (SMOSS) to help facilitate the measurement of social goals in sport. This instrument consists of three subscales—affiliation (i.e. have fun, make friends; seven items), recognition (i.e. receive recognition from others about sport involvement or ability; four items), and status (i.e. belong to the popular group; three items)—designed to measure these aspects of participants’ social motivations to sport involvement. However, the SMOSS has only been used among high school students and older adults in …


Education’S Role In A System Of Care For Children And Youth With Emotional/Behavioral Challenges: A Mixed Methods Evaluation, Lauryn Young Jan 2018

Education’S Role In A System Of Care For Children And Youth With Emotional/Behavioral Challenges: A Mixed Methods Evaluation, Lauryn Young

Theses and Dissertations

Students with more severe emotional/behavioral (EB) challenges have many problems in the school environment and subsequently have significant difficulty making adjustments later in adulthood. Coordinated care systems, such as local system of care (SOC) initiatives, were established in response to a call for reform in youth mental health services as research began highlighting the need for improved access and quality of mental and behavioral services for youth. However, even in communities where SOC initiatives are operating well, school involvement is usually marginal. Therefore, the current study aimed to evaluate education’s role in one SOC for children and youth with EB …

Significant findings indicated that all participants …


Prevalence And Predictors Of Attention Deficit Hyperactivity Disorder In Adolescent And Adult Males With Fragile X Syndrome And Autism Spectrum Disorder, Shannon L. O’Connor Jan 2018

Prevalence And Predictors Of Attention Deficit Hyperactivity Disorder In Adolescent And Adult Males With Fragile X Syndrome And Autism Spectrum Disorder, Shannon L. O’Connor

Theses and Dissertations

Individuals with fragile X syndrome (FXS) experience disproportionate rates of diagnoses of attention-deficit/hyperactivity disorder (ADHD) when compared to the general population. Exact prevalence rates and outcomes for individuals with a diagnosis of FXS and ADHD is not well known. The current study assesses rates of ADHD diagnosis in individuals with FXS as well as tests the prediction of a diagnosis of ADHD from levels of autism spectrum disorder (ASD) symptom presentation. The present study included 30 individuals with FXS aged 13-25 and were assessed using a structured diagnostic interview. Interviews were conducted with individual’s parents’ due to low cognitive ability …


Adhd Diagnosis In University Settings: The Utility Of Quantitative Eeg Coherence, Rachel M. Bridges Jan 2018

Adhd Diagnosis In University Settings: The Utility Of Quantitative Eeg Coherence, Rachel M. Bridges

Theses and Dissertations

The current study investigated the utility of EEG coherence parameters in the diagnosis of ADHD. Quantitative EEG (qEEG) analyses were performed in 35 college students with an ADHD diagnosis and 35 control students. Differences between groups were examined and the diagnostic significance of EEG coherence parameters was assessed by means of stepwise logistic regression analyses. The relation between inattentive and hyperactive/impulsive symptoms, as measured by the current symptom scale (CSS) and EEG coherence parameters was also assessed. Analyses assessing group differences using individual electrode pairings detected increased interhemispheric frontal beta-wave coherence in individuals with ADHD. Together, alpha, beta, delta, and …

Qeeg Correlates Of Cognitive Processing Speed In Children With Traumatic Brain Injuries, Joseph Ferraracci Jan 2017

Qeeg Correlates Of Cognitive Processing Speed In Children With Traumatic Brain Injuries, Joseph Ferraracci

Theses and Dissertations

Electroencephalography (EEG) and neuropsychological test measures have been previously used to understand the underlying brain changes in individuals with a traumatic brain injury (TBI). However, literature discussing the relationship between EEG and neuropsychological test performance is scarce and, further, has not been investigated explicitly in children. The purpose of this study is to investigate the cognitive and academic deficits in children with traumatic brain injury and, additionally, this study aims to understand the underlying relationship between EEG and neuropsychological test performance among this sample. Analyses included twenty-one participants between the ages of 8 and 19 years of age (male, n=14; …


Understanding Math Anxiety In Children: Deciphering The Contribution Of Math Achievement, Working Memory, And General Anxiety, Emma Kate C. Wright Jan 2017

Understanding Math Anxiety In Children: Deciphering The Contribution Of Math Achievement, Working Memory, And General Anxiety, Emma Kate C. Wright

Theses and Dissertations

Children with learning disabilities frequently have comorbid anxiety, with some experiencing Math Anxiety (MA). Presently, research on MA in children with a math learning disability (MLD) is limited, and there are no childhood electroencephalography (EEG) studies of MA exploring the neurobiological basis of MA. The current study sought (1) to examine the relationship between MA and math achievement, working memory (WM), and EEG variables; (2) to clarify the distinction between MA and MLD by controlling for GAD; and (3) to examine if WM mediates the relationship between MA and math achievement. The study included 30 children with MLD and 29 …

Emergence Of Stranger Fear In Preschoolers With Fragile X Syndrome And Idiopathic Autism Spectrum Disorder, Jessica Scherr

Theses and Dissertations

This study investigated multiple behavioral indicators of social fear and their relationship to symptoms of autism in preschool boys with atypical and normative development using a stranger approach design. Participants consisted of 101 male preschoolers that were categorized into four groups: boys with fragile X syndrome (FXS; N= 29), FXS with elevated autism symptoms (fxASD; N = 25), idiopathic autism spectrum disorder (iASD; N = 11), and typically developing boys (TD; N = 36). Results indicated specific behavioral responses to a stranger differentiated preschoolers with more severe symptoms of autism (e.g. fxASD and iASD groups) from those with low autism …


Understanding The Relationship Of Contextual Support, Peer Risk Trajectories, And School Outcomes For At-Risk Youth, Emily B. Mancil Jan 2017

Understanding The Relationship Of Contextual Support, Peer Risk Trajectories, And School Outcomes For At-Risk Youth, Emily B. Mancil

Theses and Dissertations

High school dropout (HSDO) is associated with poor life outcomes across many domains. As such, it is crucial to understand and identify the factors that contribute to HSDO risk early to increase the chance of positive student outcomes. Because students at-risk are heterogeneous, researchers recommend using pattern-centered approaches to identify subpopulations with similar risk profiles to better understand various typologies of risk. This may be a more comprehensive and accurate way to understand students atrisk for HSDO and may facilitate the development of more effective interventions. To date, seven empirical studies have used a pattern-centered approach to examine HSDO. However, …


Hope And Social Support: What Types Of Parent, Peer, And Teacher Support Matter To Early Adolescent Females And Males?, Kristin Otis Jan 2017

Hope And Social Support: What Types Of Parent, Peer, And Teacher Support Matter To Early Adolescent Females And Males?, Kristin Otis

Theses and Dissertations

In the past decade, researchers in psychology have paid increased attention to identifying psychological qualities in individuals that indicate positive mental health and flourishing. Hope has been proposed to be one of these qualities (Day, Hanson, Maltby, Proctor, & Wood, 2010; Marques, & Lopez, 2014). The majority of the hope literature has concentrated on the outcomes of differing levels of hope, but has not thoroughly examined the antecedents of hope differences. The current study provides a unique investigation of hope that looks at hypothesized antecedents of positive hope development in adolescents. For example, this study looks at the relationships among …


Antecedents Of Adolescents’ Gratitude: Personality, Social Support, And Stressful Life Events, Hannah Reckart Jan 2017

Antecedents Of Adolescents’ Gratitude: Personality, Social Support, And Stressful Life Events, Hannah Reckart

Theses and Dissertations

An increase in the emphasis of positive aspects of functioning has led to expanded attention paid to the field of positive psychology. Within in this arena, the construct of gratitude has emerged as a factor of interest, specifically in adults; however, while a basis for research of gratitude in children exists, it is lacking in breadth. Support for gratitude’s significant relations with psychosocial, psychological, and academic factors has been shown in prior research, and presumed personal and environmental antecedents of gratitude have been indicated. The present study was exploratory in nature and included a sample of 1506 students from four …


The Relation Between Quantitative Eeg Coherence And Self-Report Adhd Behavior Scale Responses, Tayllor Vetter Jan 2017

The Relation Between Quantitative Eeg Coherence And Self-Report Adhd Behavior Scale Responses, Tayllor Vetter

Theses and Dissertations

Differences in brain wave activity during resting states between adults with and without Attention-Deficit/Hyperactivity Disorder (ADHD) have been detected with electroencephalography (EEG). However, the relation between these patterns of brain wave activity and a dimensional, self-report measure of ADHD symptoms in male and female college students has never been investigated. The present study aimed to determine whether coherence, a measure of brain wave activity, can predict self-report symptoms of inattentiveness and hyperactivity in male and female college students. The analyses consisted of 14 male and 28 female adults between 18 and 27 years of age. Regression analyses were utilized to …


Conduct Problems And Student Engagement In The Classroom: Parenting Practices, Lauryn A. Young Jun 2016

Conduct Problems And Student Engagement In The Classroom: Parenting Practices, Lauryn A. Young

Theses and Dissertations

Children and adolescents with conduct problems have gained much attention due to frequency of referrals to mental health clinics, concerns with behavior within the home, and school problems. To date, evidence based positive parenting interventions have made the largest impact in producing positive student engagement outcomes within the overt engagement domains (i.e., academically and behaviorally). However, few studies have evaluated the psychological (i.e., teacher-student relationships, peer support for learning, family support for learning) and cognitive (i.e., control and relevance of school work, future aspirations and goals) covert domains of engagement. The current study aims to address this gap and measure …


Developmental Trajectories Of Working Memory From Age 6 Through 25 Years, Kristin L. Roberts Jan 2016

Developmental Trajectories Of Working Memory From Age 6 Through 25 Years, Kristin L. Roberts

Theses and Dissertations

Working memory (WM) has been shown to be closely related to measures of achievement and intelligence, as well as attention, illustrating the critical role WM plays in the learning process. Understanding the typical developmental trajectory of WM is essential if professionals are to recognize and intervene when a child’s WM development shows signs of delay. The current study evaluated the development of WM in a crosssectional sample of 303 children, adolescents, and adults from ages 6 through 25 years. The study utilized a comprehensive measure of WM, assessing verbal, static visualspatial, and dynamic visual-spatial WM capacity across various processing demands. …


Promoting Progress To Assist Youth With Disordered Eating In School Mental Health, Bryn Elizabeth Schiele Jan 2016

Promoting Progress To Assist Youth With Disordered Eating In School Mental Health, Bryn Elizabeth Schiele

Theses and Dissertations

Disordered eating has become a significant issue among children and adolescents; nearly 14% of all youth displaying disordered eating patterns. Despite the prevalence of these disorders amongst school-age students, there is a deficit of empirical literature on the integration of eating disorder support services in schools, as well as a lack of knowledge and training of school mental health (SMH) professionals regarding the appropriate interventions for this population. While eating disorders have previously been considered as outside of the school mental health domain of practice (e.g., Judge, 2001), this view has changed and there exists a significant need to provide …


Adhd Symptoms, Social Problems, And Independence In Adolescent And Young Adult Males With Fxs, Marjorie Lee Grefer Jan 2016

Adhd Symptoms, Social Problems, And Independence In Adolescent And Young Adult Males With Fxs, Marjorie Lee Grefer

Theses and Dissertations

Adolescents and young adults with fragile X syndrome (FXS) typically report a range of comorbid, impairing conditions including cognitive deficits, autism, and attention deficit/hyperactivity disorder (ADHD). Similarly these individuals experience social problems and very low levels of proficiency in independent living, which makes it extremely important to better understand what contributes to these deficits and how to potentially intervene and improve outcomes. Despite this importance, very little attention has been paid to the developmental period of adolescence in the FXS population. In addition, no previous work has utilized specific narrow band measures to probe for ADHD symptoms and instead has …


How Technology Supported Teacher Behaviors Impact Student Outcomes: Results From A 1:1 Computing Initiative, James Siddall Jan 2016

How Technology Supported Teacher Behaviors Impact Student Outcomes: Results From A 1:1 Computing Initiative, James Siddall

Theses and Dissertations

As computing technology has advanced over the last several decades, many schools and school districts have embraced the use of this technology in education. One way in which schools and school districts have adopted computing technology is through adopting 1:1 computer initiatives where each student is provided with a computing device. However, despite the widespread and continuously expanding use of 1:1 computer initiatives within the educational setting, surprisingly little is known about the classroom-level factors that may impact student educational outcomes. Only one study to date (Shapley et al., 2010) has attempted to investigate specific classroom-level factors that may impact …


Group Social Skills Interventions For Children With Aspergers: The Effects Of Parent-Guided Social Skills Software, Ryan M. Kelly Jan 2015

Group Social Skills Interventions For Children With Aspergers: The Effects Of Parent-Guided Social Skills Software, Ryan M. Kelly

Theses and Dissertations

Asperger’s syndrome (AS) has recently become controversial as a unique pervasive developmental disorder. Although it is apparently different than low-functioning autism, it has been deemed too similar to high-functioning autism (HFA) to be considered a distinct diagnosis in the DSM-5 classification system. However, despite the removal of AS from the DSM-5, research shows that both AS and HFA are significantly different than autism with cognitive impairment (intelligence quotient <= 70), and therefore have different treatment needs. These needs primarily include specialized social skills training. Youth with AS/HFA who obtain sufficient social skills often report greater levels of quality of life and lower levels of anxiety and depression. Their parents also report less parental stress. Although a growing number of evidence-based social skill interventions exist, few use an experimental design and incorporate special interest areas (i.e., the pervasive interests of children with AS), generalization techniques (e.g., different settings, parent inclusion) or computer mediation, which research suggests is needed. Using an experimental design, this study investigated the incremental benefits of parent-guided social skills software (i.e., Social Express) in improving social, emotional and behavioral functioning in the child, as well as reduce parental-stress in the parent. Thirty youths with AS/HFA enrolled in a 9-week social skills group at a clinic participated in this study, as well as their parents. Half were randomly assigned to receive Social Express. Results indicated that the treatment group showed significant improvements in social motivation compared to the control group. No significant main effects were found in regards to other social skills, internalizing problems, adaptive skills, parental stress, or life satisfaction; however, it should be noted that this study is limited by a small sample size. Other significant effects may exist, and should be investigated in the future with a larger sample size.


Behavioral And Heart-Defined Attention In Infants At High Genetic Risk For Autism, Bridgette L. Tonnsen Jan 2015

Behavioral And Heart-Defined Attention In Infants At High Genetic Risk For Autism, Bridgette L. Tonnsen

Theses and Dissertations

Characterizing early predictors of autism facilitates earlier identification, diagnosis and treatment. Although aberrant visual attention is one of the earliest identified predictors of autism and may play an integral role in developmental cascades that contribute to associated impairments, the emergence of atypical attention in infancy is poorly understood. The present dissertation includes three related manuscripts examining early patterns of visual attention in two infant samples at elevated risk for autism: infant siblings of children with autism (ASIBs) and infants with fragile X syndrome (FXS). Together, these manuscripts identify patterns of abnormal heart defined attention among ASIBs (Study 1), investigate the …
