The Application Of Bayesian Meta-Analytic Models In Cognitive Research On Neurodevelopmental Disorders, Nic Zapparrata

Dissertations, Theses, and Capstone Projects

Meta-analysis is the systematic review and quantitative synthesis of specific areas in literature and is an important quantitative tool for researchers interested in synthesizing a particular body of research. The current research used meta-analysis to investigate processing speed in two neurodevelopmental disorders. This dissertation consisted of four meta-analytic papers. The first paper was a meta-analysis that synthesized a large body of research on processing speed, measured via reaction time (RT) measures, in groups of individuals diagnosed with autism spectrum disorder (ASD) versus age-matched neurotypical comparison groups. This research was motivated by two previous meta-analyses in the literature on processing speed …

Creatively Addressing The Employment Gap: Using Creativity And The Arts To Help Autistic Adolescents And Young Adults Build Skills For Employment, Eliana Rachel Grossman

Dissertations, Theses, and Capstone Projects

Neurodiversity-affirmative autism frameworks present a shift from deficit-based models of autism to the recognition that autism is but one of many facets of biodiversity that should be affirmed and embraced. However, there is little research examining links between creativity and autism that has adopted a neurodiversity-affirming approach. The dissertation aimed to expand upon the nascent interdisciplinary link between neurodiversity-affirmative autism research and creativity to 1) understand the creative experiences of autistic adolescents and young adults and 2) address the critical issue of chronic unemployment faced by autistic people.

The first study examined the perspectives of autistic adolescents and young adults …

Examining Visual Processing Of Hierarchical Figures Through Behavioral Measures And Pupillometry In Relation To Autistic Traits In Adults, Chloe Brittenham

Dissertations, Theses, and Capstone Projects

Autism spectrum disorder (ASD) and autistic traits in the general population are associated with differences in sensory processing, particularly within the visual domain. Previous studies examining global (i.e., overall gist) and local (i.e., detail) visual processing in relation to ASD have sometimes yielded contradictory findings yet converge on a common theme: slowed global processing and increased local bias associated with ASD. Despite this consensus, the mechanism underlying these differences remains unclear, whether it be differences in visual attention, higher or lower visual perception, and/or cognitive style. The use of traditional tasks and stimuli may further complicate the understanding of contributing …

The Relationship Between Autistic Traits, Autistic Camouflaging, And Adults’ Representations Of Abstract And Social Concepts, Henry Tomiser, Katja Wiemer Dr.

Honors Capstones

Concrete concepts (e.g., BUTTON) can be experienced directly by the senses, whereas abstract concepts (e.g., FRIENDSHIP) cannot. Additionally, the mind may represent abstract concepts using more introspective, social, and emotional information than concrete concepts. Social difficulties are one defining feature of autism, and autistic individuals may use social camouflaging to hide these difficulties, but the precise nature of social processing in autism is not known. This study aims to explore possible links between autistic traits, autistic camouflaging, and mental representations of concepts. Participants gave open-ended definitions for concepts varying in concreteness and social content via an online survey. Responses were …

Hospital Provider Knowledge Of Behavioral Function And Management Of Severe Behavior For Patients With Autism, Giovanna Salvatore Devito

Theses and Dissertations

Hospital patients with autism spectrum disorder (ASD) may engage in various topographies of severe behavior, with higher rates of restraint implemented than for their neurotypical counterparts. Qualitative research suggests that physician knowledge of function-based intervention is limited. Multidisciplinary behavior management teams were developed to decrease restraint across general hospital patients. In Study 1, the research team developed the Knowledge of Behavioral Function (KoBF) survey measure, using an iterative user-centered development process and administered the measure to multidisciplinary physicians and trainees. Results indicated low knowledge of behavioral function, with a mean percent correct of 66.60% on close-ended survey items and 14% …

Investigating The Relation Between Family Income And Barriers For Black Caregivers Of Autistic Children, Leah Gelfand

Psychological Science Undergraduate Honors Theses

Black caregivers and families of autistic youth experience racial barriers (e.g., racial microaggressions, stigma;) and practical barriers (e.g., cost of treatment, long waitlists), when seeking treatment and diagnostic services (Lovelace et al., 2018). The current study aimed to ascertain whether family income influenced the racial and practical barriers experienced by a sample of Black caregivers of autistic youth (N = 101). Overall and item-level analyses were conducted to explore the relationship between racial and practical barriers experienced across Lower (below 39,693; n=32), Lower-Middle ($39,693-$59,540; n=28), Middle-Upper ($59,540 to $119,080; n=21), and Upper income groups ($119,080 and …

Listening To Transgender And Autistic Voices: Reflecting On Affirming Research And Mental Health Practices, Kameron Bm Kirbyson

Electronic Thesis and Dissertation Repository

Those who are both autistic and transgender/gender diverse, an often-overlooked group, face difficulties accessing gender-affirming care and appropriate therapy and have higher rates of mental health complications. This study focused on listening to the voices of people who live with both of these identities through semi-structured interviewing and by centring the writer who is also autistic and transgender. Seven participants shared their experiences and highlighted issues they have come up against while trying to access care. Thematic analysis revealed several themes that were sorted into barriers and strengths. Barriers included autism symptoms, complex medical factors, interactions with institutions, traumatic events, …

A Longitudinal Study Of The Development Of Social Anxiety In Young Autistic Children, Gillian K. Marshall

Senior Theses

Social anxiety is a prevalent anxiety disorder marked by fear and discomfort in social situations where scrutiny or evaluation by others is anticipated. This thesis investigates the interplay between social anxiety and autism spectrum disorder (ASD), a neurodevelopmental condition characterized by social and communication challenges. Individuals with ASD often face heightened levels of anxiety, intensifying their social difficulties and impeding their social development. Early identification of social anxiety symptoms, particularly in ASD children, is crucial for timely intervention and improved outcomes. However, diagnosing social anxiety in preschool-aged children, especially those with ASD, presents challenges due to the complexity of symptoms …

A Comparison Of Symptom Profiles In Probands With 16p11.2 Deletion And Duplication Syndromes: Repetitive Behavior And Psychosis Proneness, Adrianna Rakauskas

Honors Theses

The present study examines two classes of behavior in probands with the 16p11.2 duplication and deletion: repetitive behavior and psychosis spectrum behavior. It was hypothesized that 1.) deletion and duplication cases will differ significantly in the means and profiles of repetitive behaviors across five subscales and 2.)16p11.2 duplication cases will exhibit more schizotypal traits than the deletion cases. Data on 94 total participants was obtained from the Simmons Variation Individuals Project. Three scales were used to measure behavior: the Childhood Routines Inventory-Revised, the Childhood Oxford-Liverpool Inventory of Feelings and Experiences, and the Child Behavior Checklist. Data analysis was conducted using …

Internalizing Symptoms In Autistic Young Adults: Comparing The Cognitive And Physiological Components Of Emotion Regulation, Sarah Lehman

Master's Theses (2009 -)

Autistic people experience co-occurring mental illness at a substantially greater rate compared to their neurotypical counterparts. Of these comorbid psychopathologies, internalizing disorders (anxiety and depression) are among the most prevalent. Emotion dysregulation has been identified as a contributing factor to this phenomenon and potential treatment target. The current study employed cognitive (e.g., use of suppression and use of cognitive reappraisal) and physiological (e.g., respiratory sinus arrhythmia (RSA) and heart period) measures to more holistically capture the multifaceted construct of emotion regulation compared to prior research. In a sample of autistic young adults (N = 63) ages 17-29 (M = 20.14), …

Investigating Neural Mechanisms Associated With The Double Empathy Problem Using Fnirs Hyperscanning, Kate E. Turner

Electronic Thesis and Dissertation Repository

The Double Empathy Problem posits that autistic social difficulties are due to differences in communication styles rather than an autistic deficit in theory of mind (ToM). We used fNIRS hyperscanning to examine whether neural synchrony in pairs with varying levels of autistic traits during social interactions supports the Double Empathy Problem. Participants with low and high autistic trait expression were paired creating High-High, Low-High, and Low-Low groups. Pairs completed two trials where they 1) listened to and 2) discussed stories that contained or lacked theory of mind elements, while brain activity was recorded within the ToM network. During conversation, High-High …

Teaching Peer Imitation To Preschool-Aged Children With Autism Spectrum Disorder Using A Video Modeling Treatment Package, Megan M. Harper

Theses & Dissertations

Peer imitation is a skill that serves to promote the acquisition of new play skills, problem-solving skills, and academic skills through observation of one’s peers. Although peer imitation is an important pre-requisite for learning from peers, many autistic children experience deficits in this area. In the present study, we evaluated a video model treatment package to teach autistic children to imitate their peers. Additionally, we conducted free play probes pre- and post-training to assess the transfer of training to a natural play setting. The results of the current study are mixed. One participant’s imitation skills generalized to the in-vivo sessions …

Coaching In Differential Attention And Pride Skills During Child Directed Interactions For Siblings Of Children With Neurodevelopmental Disorders, Ava Sardoni

Dissertations, 2020-current

Neurodevelopmental Disorders (NDDs) are an increasingly-common presentation that is often associated with significant behavioral and relational challenges. NDDs can impact multiple areas of functioning including social, academic, and adaptive functioning. As NDDs are developmental disorders in nature, they are often lifelong conditions that require intensive treatments and adaptations throughout the lifespan. One of the most important predictors of success and fulfillment for a child with an NDD is the support from the family system.

Siblings of a child with an NDD are often neglected from the conversation of supports and treatments for children with NDDs. However, challenging behaviors often associated …

Behavioral And Eye-Movement Correlates Of Item-Specific And Relational Memory In Autism, Greta Nicole Minor

Theses and Dissertations

Recent work has challenged past findings that documented relational memory impairments in autism. Previous studies have often relied solely on explicit behavioral responses to assess relational memory integrity, but successful performance on behavioral tasks may rely on other cognitive abilities (e.g., executive functioning) that are impaired in some autistic individuals. Eye-tracking tasks do not require explicit behavioral responses, and, further, eye movements provide an indirect measure of memory. The current study examined whether memory-specific viewing patterns toward scenes differ between autistic and non-autistic individuals. Using a long-term memory paradigm that equated for complexity between item and relational memory tasks, participants …

Executive Functioning In Children With Autism And Co-Occurring Neurodevelopmental Disorders: A Systematic Review And Quantitative Analysis, Kandice Benallie

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Children with autism and other NDDs experience some level of executive dysfunction including challenges with problem-solving, judgement, working memory, and flexibility. Considering autism and other NDDs including ADHD and ID have overlapping symptoms, it can be difficult to differentially diagnose the disorders. This dissertation sought to explore how co-occurring ADHD and ID impact the EF of autistic children. The first study systematically reviewed the current research examining EF of autistic children with co-occurring ADHD and ID. Findings suggest that co-occurring ADHD and ID result in increased executive dysfunction as compared to children with autism only. The systematic review also revealed …

App-Based Academic Interventions For Children With Autism, Cassity R. Haverkamp

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Technology, such as tablet/phone apps, robots, video games, and virtual reality, can be used to teach skills to autistic children. Research on technology supports for autistic youth often focus on social skills, a main part of an autism diagnosis. However, autistic children may also have academic challenges, and fewer studies have looked at how technology can teach academic skills to children with autism. We created three studies to look at how academic apps may benefit autistic children. In the first study, we reviewed studies that looked at how academic apps can increase the academic skills of children with autism. We …

Exploring Levels Of Autism Symptom Support After Eligibility Determinations, Zachary Bella

Theses and Dissertations

The identification of autism spectrum disorders (ASD) occurs in educational and health settings. Many children with autism will only receive a classification of autism in the educational setting (Esler et al., 2022, Pettygrove et al., 2013, Wiggins et al., 2020). There is significant overlap between the early intervention offered to children with autism in health settings and what is provided through Individualized Education Programs (IEPs) (National Autism Center, 2009; Morset et al., 2010). However, there is an increasing trend of children with autism being classified with significant developmental delay (SDD) instead of autism initially in schools and the impact of …

Autism, Comorbidities, And Adaptive Functioning: A Potential Moderator, Joshua J. Montrenes

LSU Doctoral Dissertations

Deficits in adaptive functioning and the presence of comorbid symptomatology are both commonly associated with autism spectrum disorder (ASD). Previous research has identified relationships between functional level (e.g., intellectual quotient [IQ], adaptive functioning [AF]) and comorbid symptomatology in ASD. However, further insight into the relationship between AF, comorbid psychopathology, and ASD is unclear. Specifically, how AF affects the relationship between ASD and comorbid conditions is not well understood. Whether AF moderates the relationship between autism symptom severity and comorbid symptom severity in toddlers with ASD was examined. ASD symptom severity positively correlated with comorbid symptom severity across domains and negatively …

Parent Facilitation Of Child Emotion Regulation In Autism Spectrum Disorder, Aimee K. Rovane

Theses and Dissertations

Parents play a substantial role in their children's emotional regulation (ER) abilities, promoting both adaptive and maladaptive development. Children with autism spectrum disorder (ASD) often have difficulties regulating their emotions, manifesting in externalizing behavioral issues (Mazefsky & White 2014). Though there are many similarities to parents of typically developing (TD) children, parents of children with ASD facilitate their children's ER development (i.e., emotion socialization) in response to unique challenges, often developing resiliency but other times contributing to their children’s dysregulation and behavioral challenges. Using Morris et al.'s (2007) Tripartite Model of Family Impact of Children's Emotion Regulation and Adjustment as …

Comparing Teaching Methods For Auditory-Visual Conditional Discrimination, Brady Conley, Robbie Hanson

Theses

Responding to spoken language is a skill that is typically acquired at a young age. However, responding to spoken language requires discrimination between stimuli. Many individuals with autism spectrum disorder (ASD) have demonstrated difficulty acquiring listener behavior involving conditional discrimination. Thus, the most efficient and effective teaching strategies should continue to be a focus in behavior-analytic research. The purpose of the current study was to compare teaching methods for conditional discrimination for three school-aged children with ASD. The results showed that one participant met criterion for the best practice condition only, one participant met criterion for both best practice and …

Using Video Prompting For Daily Living Skill Acquisition In Adults With Intellectual And Developmental Disabilities, Meghan Park Mitchell

Masters Theses, 2020-current

The current study examined the effects of video prompting on the acquisition of a daily living skill with adults who have intellectual or developmental disabilities (IDD). A multiple baseline across participants design was used to assess whether a video prompting procedure was able to teach adults with IDD a daily living skill with minimal socially mediated instruction. It was found that performance increased once the intervention was applied. Future directions for research and application in teaching daily living skills to adults with IDD are discussed.

The Effects Of A Self-Recording Procedure On Student’S On-Task Behavior, Maria Leventhal

Masters Theses, 2020-current

This study investigated the isolated effects of self-management on students on-task behavior through an operant analysis. Two elementary-aged students, receiving ABA services at a special education school were taught to self-record their on-task behavior using a Gymboss miniMAX timer that cued them at variable intervals. Following baseline, students were trained to self-record using Behavior Skills Training. A series of phases was then implemented to gradually increase the intervals. To isolate the effects of self-recording, feedback and reinforcement were not provided. Using a multiple baseline across participants design, a functional relation was demonstrated between self-recording and on-task behavior.

This study aimed to close the gap in literature and explore to see if there were any concerns that could be addressed by future studies. The study was framed around Bowen’s theory, which addresses emotions within a family unit, and the interdependence theory, which addresses how humans thrive to be …

Focusing On Friendship: Online Supported Activities For Adolescents On The Autism Spectrum, Molly King

Psychology Doctoral Specialization Projects

A core feature of Autism Spectrum Disorder (ASD) is social skills differences. Social skills groups have received support as an intervention that fosters social skills of those with ASD. However, there is limited information about the use of telehealth-based social skills groups. The proposed ASD adolescent social group design is formatted for telehealth services, and has been conducted virtually since 2020. This ASD social group program features unique virtual teaching and recreational activity curriculum as well as some program evaluation data methods and responses from participants.

Finding Confidence, Balance, And Self-Acceptance: A Clinician’S Guide To Treating Involuntary Celibates, Brian Keller

Psychology Doctoral Specialization Projects

Involuntary Celibates (incels) are a new and poorly understood population. In the field of psychology, very little research has been done on the population, and even fewer clinicians have successfully worked with clients from this group. This handbook was created in an attempt to outline the history, belief system, terminology, and common mental health problems of incels and their related groups. This information is distilled down and presented as a primer for anyone looking to understand this new population. Also, possible treatment recommendations are suggested and discussed in detail based on the particular psychological difficulties that incels often face.

Self-Diagnosis & Pathologizing Normality During The Information Age, Chelsey Eaton

Murray State Theses and Dissertations

Self-diagnosis has become a concern for medical and mental health diagnoses. More people are engaging in self-diagnosis based on information that was obtained from the internet, including websites, social media platforms, and online forums. There are several reasons one may choose to self-diagnose. Some common reasons outlined in research are the desire to fit in with others who share similar characteristics and having a label to explain one’s experiences. Past research has shown that people frequently search for mental health information online, but they may not understand or may misinterpret the information that is found. This study aimed to address …

Characteristics Of Anxiety In Autistic Adults, Melissa Lewis

Honors Undergraduate Theses

Modern Autism Spectrum Disorder (ASD) research has shifted in focus from explaining a debilitating childhood illness to helping individuals of all ages, cultures, and intelligence navigate their social problems. Understanding of the adult perspective has also grown massively since the autism diagnosis changed in the Diagnostic Statistical Manual, Fifth Edition (DSM-5) in 2013 and has brought into question how the neurodevelopmental disorder affects the individual. Anxiety symptoms in ASD, like the existence of camouflaging, have proven unique only to ASD, and recent findings suggests that the cause of anxiety in autistic individuals may be due to fundamental differences in communication …
