Gaining Computational Insight Into Psychological Data: Applications Of Machine Learning With Eating Disorders And Autism Spectrum Disorder, Natalia Rosenfield

Computational and Data Sciences (PhD) Dissertations

Over the past 100 years, assessment tools have been developed that allow us to explore mental and behavioral processes that could not be measured before. However, conventional statistical models used for psychological data are lacking in thoroughness and predictability. This provides a perfect opportunity to use machine learning to study the data in a novel way. In this paper, we present examples of using machine learning techniques with data in three areas: eating disorders, body satisfaction, and Autism Spectrum Disorder (ASD). We explore clustering algorithms as well as virtual reality (VR).

Our first study employs the k-means clustering algorithm to …

College Supports For Asd: Autistic Perspectives Across Educational Career, Rachel Stanley

Master's Theses (2009 -)

Higher education has become a viable pursuit for many autistic individuals, but those who seek a college degree graduate at rates significantly lower than their peers. Social skills, mental health, executive functioning, independent living, and sensory processing are highlighted as areas of difficulty for autistic college students. However, research seeking the perspectives and experiences of autistic individuals has been limited, and proposed solutions are not based on input from the population they seek to serve. Further, research has been largely limited to current college students, and may miss potentially useful perspectives on transition from individuals pre- and post-college. This study …

How Can I Help My Anxious Child With Autism Spectrum Disorder? Understanding Parental Perspectives And Treatment Preferences, Sandra L. Cepeda

USF Tampa Graduate Theses and Dissertations

Despite the high prevalence of co-occurring anxiety in children with autism spectrum disorder (ASD), little is known about parental preferences for treatment in addressing these anxiety concerns. Understanding parents’ preferences for treatment is an important factor to consider for ensuring quality care, as it can guide clinical decisions with regard to implementation of care, strategies for optimizing engagement and treatment adherence, and is associated with treatment outcome. To date, limited studies have examined parental preferences in treatment for childhood anxiety or ASD; but no study has investigated preferences for treatment in children with comorbid symptoms. Thus, the present study sought …

Autism And Externalizing Behaviors: Attachment As A Protective Factor, Rebecca Kramer

Clinical Psychology Dissertations

Children with autism spectrum disorder (ASD) exhibit externalizing behaviors at a higher rate when compared to their typically developing (TD) counterparts (Bauminger, Solomon, & Rogers, 2010; Gray, Keating, Taffe, & Brereton, 2012). Numerous longitudinal and cross-sectional studies assert that attachment is one of the most salient predictors of childhood externalizing behaviors (e.g., Green and Goldwyn, 2002). Despite this, little research has examined the relation between attachment and externalizing behaviors in children with ASD. This study investigated the extent to which high levels of attachment buffer the symptoms of externalizing behaviors in children with ASD, potentially informing future interventions. In addition, …

Impacts Of Motor And Sensory Impairment On Language In Young Children With Autism, Elizabeth A. Bisi

Clinical Psychology Dissertations

Children with autism spectrum disorder (ASD) present with varying degrees of deficit in the broader areas of social communication and stereotyped behaviors, but emerging research proposes delayed motor skill and atypical sensory processing as additional factors worth closer examination. In the current study, I sought to investigate the impacts of visual motor skills and sensory differences on language ability in young children with autism. I hypothesized that young children with autism, atypical sensory processing (Short Sensory Profile, 2^nd Edition), and impaired visual motor integration (Beery VMI, 6^th Edition) would have the most impacted language ability scores (Differential Ability …

Teaching Children With Autism To Make Independent Requests Using An Echoic-To-Mand Procedure, Michael L. Tomak

Dissertations

Mands are a vital skill for the development of a child’s communicative repertoire and are typically a major focus of early intensive behavior interventions (EIBI). Naturalistic teaching is more efficient than Discrete-Trial Training (DTT) for teaching mands (Jennet, Harris, & Delmolino, 2008); and therefore, the present study used crucial components from naturalistic teaching to teach mands in a discrete-trial format, using an echoic-to-mand procedure. This intervention increased the children’s independent vocal requests. Initially, they learned to mand for items in sight and eventually for those out of sight.

Using A Video Modeling Treatment Package To Teach Imitation To Children With Autism, Sofia F. Peters

Dissertations

Imitation is a critical skill that allows individuals to learn through less restrictive prompting methods and may allow access to less restrictive learning environments, such as typical classrooms, where instruction is often delivered by modeling. Many individuals with autism learn to imitate with interventions that utilize live models and least-to-most prompting strategies; but, for some, these methods are not successful or efficient. While video modeling has been used to teach a variety of skills to individuals with autism, there is limited research using video modeling to teach imitation. This study investigated the effectiveness of using a video modeling treatment package …

Exploring Influences On Autistic Identity Development In Adolescence And Early Adulthood, Ariana Riccio

Dissertations, Theses, and Capstone Projects

Personal identities grow and change across development, co-constructed and renegotiated within our environment, through our interactions, and by our relationships with the people and places around us. This dissertation aimed to explore the development of autistic identity in adolescence as influenced by parents, introduces a novel method for measuring emotions and autistic identity where participants rate their emotional responses to autistic experiences, and explores the influence that colleges and universities may have on autistic identity in young autistic adults.

In a study of 19 autistic adolescents and their parents, if and how parents disclosed an autism diagnosis to their child …

Development Of An Aba Tool Kit For Audiologists To Increase Hearing Aid Wear Time In Individuals With Autism, Lindsay Brown

Dissertations, Theses, and Capstone Projects

When working with individuals with the dual-diagnosis of hearing loss and Autism Spectrum Disorder (ASD), audiologists are often faced with unique challenges and must adapt their approach in order to more effectively address the needs of these individuals. Currently, there is only a small body of research focused on the special considerations required for appropriately fitting and utilizing amplification for children with the dual-diagnosis of hearing loss and ASD. Subsequently, recommendations and strategies for clinicians to implement when faced with these common challenges, specifically of hearing aid compliance and appropriate hearing aid wear time, are lacking. It is important to …

Analysis Of An Antecedent Prompting Error Correction On Rates Of Disruptive Behaviors And Compliance In Children Diagnosed With Autism Spectrum Disorder, Emily Knox

Masters Theses, 2020-current

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder whose defining characteristics include deficits in social communication and restricted, repetitive patterns of behavior, interests, and/or activities (Weiss, Baker, & Butter, 2016). Children diagnosed with ASD frequently engage in disruptive and destructive behaviors that have the function of escaping from work demands. These behaviors impact their ability to contact important instructional material, further impacting their levels of independence. Practitioners typically intervene on these behaviors using interventions that rely heavily on consequence-based interventions. Although there is an abundance of research on effective consequence-based interventions to treat these behaviors, these interventions are often difficult …

A Pilot Investigation Of The Relationship Between Derived Relational Responding And Challenging Behavior Function, Kaitlin N. Beason

Graduate Theses/Dissertations

The study evaluated the relationship between participants derived relational responding across arbitrary stimuli and parent or teacher endorsed functions of challenging behavior as assessed on the Questions About Behavior Function (QABF). Supplemental analyses were conducted to directly observe the frequency and intensity of challenging behavior using the Challenging Behavior Index (CBI), as week as direct observation of presenting autism symptoms in session using the PEAK Autism Symptoms and Behavioral Observation Summary (PAS-BOS). Derived relational responding was assessed using the Promoting the Emergence of Advanced Knowledge Equivalence Pre-Assessment (PEAK-E-PA) and the Promoting the Emergence of Advanced Knowledge Transformation Pre-Assessment (PEAK-T-PA) taking …

Evaluating Correlations Between The Peak Equivalence And Transformation Assessments With Intelligence Quotient Scores And The Relational Acquisition Of Skills In Children With Autism, Hannah L. Wallace

Graduate Theses/Dissertations

The purpose of the present study was to evaluate correlations between PEAK Equivalence and Transformation assessment scores to Intelligence Quotient (IQ) scores in children with autism. An assessment called the Relational Acquisition of Skills in Children with autism (RASC) was created as a pilot test. This method was used to test relational responding in young children with autism. The scores of this assessment were correlated with scores obtained using PEAK Equivalence and Transformation assessments and IQ. It was found that PEAK Equivalence and Transformation assessments had a strong positive correlation with IQ. No significant relationship between the Relational Acquisition of …

Effects Of Peak Equivalence And Transformation Treatment On Derived Relational Responding As A Generalized Operant And Iq, Lindsey Schneider

Graduate Theses/Dissertations

The present study examined Promoting the Emergence of Advanced Knowledge Relational Training System; Equivalence (PEAK-E) and Transformation’s (PEAK-T) effect on a participant with ASD’s derived relational responding, intelligence scores (WPPSI-IV; Weschler 2012), and the deceleration coefficient. One participant with ASD was given 10 weeks of PEAK-E and PEAK-T treatment for four hours a week, along with probes throughout the study for IQ scores and deceleration coefficient scores. The data indicated a significant relationship between PEAK-E and PEAK-T treatment and IQ scores, as well as a relationship between PEAK scores and a participant’s deceleration coefficient. This indicated that PEAK-E and …

Searching For Neural Mechanisms Of Social Cognition, Chandler Siemonsma, Cristina Uribe, Louanne Boyd, Aaron Schurger, Deanna Hughes, Tian Lan

Student Scholar Symposium Abstracts and Posters

Social cognition involves the integration and pruning of perceptual information which leads to the formation of an abstract representation, which is also known as the perceptual gist. This study examined 87 differences in visual perception of Mooney face stimuli of differing sizes and the relationship to gist formation in ten individuals with autism compared to neurotypical controls. Parents of both groups completed the Social Responsiveness Scale (SRS-2) to assess social functioning in real-world scenarios.

Combining Eye Tracking And Verbal Response To Understand The Impact Of A Global Filter, Franceli L. Cibrian, Jazette Johnson, Viseth Sean, Hollis Pass, Louanne Boyd

Engineering Faculty Articles and Research

Visual attention guides the integration of two streams: the global, that rapidly processes the scene; and the local, that processes details. For people with autism, the integration of these two streams can be disrupted by the tendency to privilege details (local processing) instead of seeing the big picture (global processing). Consequently, people with autism may struggle with typical visual attention, evidenced by their verbal description of local features when asked to describe overall scenes. This paper aims to explore how one adult with autism see and understand the global filter of natural scenes.

Stimulus Fading On Teaching Receptive Identification, Dennis Pomorski

Honors Theses

Many of the skills needed to live happily and independently are not in the repertoires of children diagnosed with autism, and they do not learn these skills through exposure to others (MacDuff, 2001). One of the skills children diagnosed with ASD struggle to develop is receptive identification. There is often a risk of prompt dependence or failure to transfer stimulus control to the desired stimuli when using LTM prompting methods. Children with autism spectrum disorder may require a different approach in developing a receptive language repertoire. The purpose of this study was to teach a child diagnosed with ASD receptive …

Theses and Dissertations

The present study evaluated telehealth training with parents on techniques for working with their children with autism spectrum disorder in Southeastern Europe. The purpose of this study was to research the effects of telehealth training on the parents and the increase of mands on the children. The participants of this study included three mothers and three children, which totaled six participants. Parents were trained on how to increase functional communication in their child. Telehealth training was based on an effective training package called Behavior Skills Training (BST). BST consist of instructions, modeling, rehearsal, and feedback. The resources needed for the …

Teaching Echoics To A Student With Autism: Video Model Vs Live Model, Dana Waddell

Honors Theses

Learning a language is not always an easy task for all children. Typically, language is a skill that comes naturally very young in a child’s life, but for children with autism, the path to learning language is very different. The first stages of learning language involve many skills, one of which are called “echoic skills,” because the child directly echoes a sound a person elicits. This is fundamental to learning language, especially in children with autism. The field of behavior analysis has conducted great amounts of research on this topic and has found that using technology in therapy sessions can …

Matching-To-Sample Using A Tablet, Karina Salazar-Ponce

Honors Theses

Kids with autism tend to have a difficult time with one-to-one correspondence matching. Matching-to-sample is the process of pairing an identical stimulus to its corresponding stimulus, for example, matching a physical object to its corresponding picture. This is an important skill because it is the first step in teaching individuals with developmental delays visual discrimination skills and generalization of matching. The use of technology is beneficial because it helps with attending in instructional learning. Technology is also becoming more advanced and is being used more in classrooms. The purpose of this study was to teach matching-to-sample using a tablet. There …

Using A Progressive Time Delay To Increase Mands In A Child With Autism, Brielle Babcock

Honors Theses

Mands are a building block for all communication and are therefore important to teach to individuals who do not consistently use mands. Skinner defined a mand as a “verbal operant in which the response is reinforced by a characteristic consequence and is under the control of relevant conditions of deprivation or aversive stimulation” (Hall & Sundberg 1987). By providing individuals with a way to express their desires and needs, individuals display less problem behaviors. A functional form of communication is imperative to typically developing children and children with autism spectrum disorders alike. The goal of the current study was to …

Increasing The Echoic Repertoire Of A Child With Autism Using An Imitation And Echoic Sequence, Rose Bridges

Honors Theses

A prerequisite to many things in life is the ability to communicate. Although this may mean many different things, such as verbal language, sign language, written language, and even icons, there must be some form of communication that may be utilized to get needs across. Many young children with autism spectrum disorder (ASD) are non-verbal, however there are also many children with ASD who have the ability to say words but are still not independently speaking. Reinforcing approximations to word sounds has been previously used as an effective way of increasing the child’s verbal repertoire (Shane, 2017). The present study …

The neuro-oncological ventral antigen 2 (NOVA2) protein is a major factor regulating neuron-specific alternative splicing (AS), previously associated with an acquired neurologic condition, the paraneoplastic opsoclonus-myoclonus ataxia (POMA). We report here six individuals with de novo frameshift variants in NOVA2 affected with a severe neurodevelopmental disorder characterized by intellectual disability (ID), motor and speech delay, autistic features, hypotonia, feeding difficulties, spasticity or ataxic gait, and abnormal brain MRI. The six variants lead to the same reading frame, adding a common proline rich C-terminal part instead of the last KH RNA binding domain. We detected 41 genes differentially spliced after NOVA2 …

Impact Of A Social Skills Intervention On The Structural Anatomy Of The Social Brain Of Autistic Adolescents, Alexis Arias

Master's Theses (2009 -)

The prevalence of Autism Spectrum Disorder (ASD) continues to rise as researchers seek to examine the physiological links to social and communication challenges. The Social Brain, neuroanatomical structures which play a role in social cognition, is proposed to be linked to the social and communication challenges associated with ASD. An area of rapidly growing research is the evaluation of social skills interventions, which target social challenges present in Autistic individuals. Advances in technology, have allowed for these interventions to be examined in regards to physiological changes (e.g., electroencephalogram asymmetry and coherence) as outcome variables. Amongst these interventions, the Program for …

Malleability Of Neural Activity In Response To Treatment: Fmri Biomarkers Across Intervention For Autistic Adolescents, Alana J. Mcvey

Dissertations (1934 -)

Autistic adolescents frequently experience clinical levels of anxiety which exacerbate social difficulties. Those that receive a well-validated social skills intervention, the Program for the Education and Enrichment of Relational Skills (PEERS®), have shown improvements in both social behavior and anxiety. Prior literature has demonstrated neural changes in response to this intervention using EEG, and recent literature highlights the importance of using neural markers to assess for intervention response in autism. No study to date, however, has examined changes in neural activity via fMRI and links with social behavior and anxiety across the PEERS® intervention for autistic adolescents. Thus, the present …

Preliminary Psychometrics For The Executive Function Challenge Task: A Novel, “Hot” Flexibility, And Planning Task For Youth, Lauren Kenworthy, Andrew Freeman, Allison Ratto, Katerina Dudley, Kelly K. Powell, Cara E. Pugliese, John F. Strang, Alyssa Verbalis, Laura G. Anthony

Psychology Faculty Research

Objective: Executive functions (EF) drive health and educational outcomes and therefore are increasingly common treatment targets. Most treatment trials rely on questionnaires to capture meaningful change because ecologically valid, pediatric performance-based EF tasks are lacking. The Executive Function Challenge Task (EFCT) is a standardized, treatment-sensitive, objective measure which assesses flexibility and planning in the context of provocative social interactions, making it a “hot” EF task. Method: We investigate the structure, reliability, and validity of the EFCT in youth with autism (Autism Spectrum Disorder; n = 129), or attention deficit hyperactivity disorder with flexibility problems (n = 93), and typically developing …

How Does Autism Affect The Processing Of Child Sexual Abuse Trauma?, Jose Carbajal, Regina T. Praetorius

Journal of Human Services: Training, Research, and Practice

Children in general are a vulnerable population, but children with neurodevelopmental disorders are even more vulnerable. This case study, which uses secondary qualitative data to focus on a survivor of sexual abuse who has autism, explores how a child with autism interprets and processes being sexually abused. We contrast how a child with autism experiences child sexual abuse with the experiences of children without autism; major differences emerged in terms of how a child with autism normalizes and interprets sexual abuse. The findings of this study indicate mental health professionals need more training regarding the complications autism adds to the …

The Heterogeneity And Wide Range Of Autism Spectrum Disorders, Nikki Johnson

Augsburg Honors Review

Autism spectrum disorder (ASD) is one of the most prevalent childhood neurological disorders in the US (Pinel et a1.,2011). Individuals with this disorder experience a varying degree of lower capacity for social interaction and communication. There are two important characteristics of ASD, its heterogeneity and its range of disorders on a wide spectrum, which must be kept in mind as research is performed on this topic. This complexity of ASD and its large amount of individual variation, based on the intensity, behaviors, and types of disorders a person has, makes it difficult to uncover the pathophysiology of these neurological disorders. …

Saccade Latency Provides Evidence For Reduced Face Inversion Effects With Higher Autism Traits, Robin Laycock, Kylie Wood, Andrea Wright, Sheila G. Crewther, Melvyn A. Goodale

Brain and Mind Institute Researchers' Publications

© Copyright © 2020 Laycock, Wood, Wright, Crewther and Goodale. Individuals on the autism spectrum are reported to show impairments in the processing of social information, including aspects of eye-movements towards faces. Abnormalities in basic-level visual processing are also reported. In the current study, we sought to determine if the latency of saccades made towards social targets (faces) in a natural scene as opposed to inanimate targets (cars) would be related to sub-clinical autism traits (ATs) in individuals drawn from a neurotypical population. The effect of stimulus inversion was also examined given that difficulties with processing inverted faces are thought …
