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 …

Survey On Services Provided To Children With Autism Spectrum Disorder In U.S. Public Schools, Kendra Mcpherson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is of utmost importance that students diagnosed with Autism Spectrum Disorder (ASD) in the public school setting across the United States are receiving the best, most researched services and treatments. This study aimed to find out what services and treatments are most commonly being used for students with ASD in the public schools, to see whether or not those practices are supported by research, and to discover how involved parents and families are in the services being provided to their students. This study found that of the top 25 most commonly used practices, 17 of those were supported by …

Training Parents In Descriptive Assessment And Function Identification, Makenzie Sip

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is often difficult for parents to address their child’s problem behavior. Children with special needs can display more frequent and intense problem behavior. Therefore, professionals need to help parents of children with special needs identify how to decrease their child’s problem behavior. Professionals help to decrease problem behavior by performing assessments called descriptive assessments to identify why the problem behavior is happening, and then using these assessments to create an appropriate plan of how to prevent and respond to the problem behavior. We examined if parents could be taught the skills necessary to perform descriptive assessments and then use …

An Evaluation Of Demand Functions For Attention And Food In Children With Autism, Bistra K. Bogoev

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The dominant approach to treating social dysfunction in individuals with autism views that dysfunction as a skill deficit. However, another plausible interpretation is that social dysfunction in some individuals arises from motivational deficits. The proposed study presents a method to assess motivational deficits for social attention in individuals with autism. By borrowing methods from behavioral economics, we assessed the essential value for social attention and compared it to the essential value for food.

Five individuals diagnosed with autism were included in the project. First, we assessed preference for food by using paired-preference assessment. To identify preference hierarchy for attention, we …

An Analysis Of Auditory Stimulus Generalization Gradients In Children With Autism Following Two Different Training Procedures, Steven N. Corry

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Previous research suggests learning of children with autism often fails to successfully generalize across changes in settings and stimuli. Much of this research has assessed generalization by first teaching a behavior in one context and then measuring the transfer of the behavior to extra-treatment stimuli and settings. The present study measured generalization of learned behavior by systematically varying the tone of an auditory stimulus present during training to obtain generalization gradients. Generalization gradients are graphical representations of the strength of a response produced by stimuli that vary from the training stimulus along some stimulus dimension. By obtaining generalization gradients, this …

Social Skills Intervention For Students With Autism Spectrum Disorders: A Survey Of School Psychologists, Amanda S. Day

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Social skills interventions for students with autism spectrum disorders (ASD) are needed as the number of students with ASD are increasing in educational settings. The purpose of this study was to investigate school psychologists' perceptions on the effectiveness and generalization of social skills interventions for students with ASD. Training and confidence of providing services to students with ASD was also examined in the study. A survey was administered to a sample of school psychologists from the National Association of School Psychologists (NASP). In total, 221 responses were received and 136 of those responders indicated that they have implemented or organized …

Examination Of Behavioral Momentum With Staff As Contextual Variables In Applied Settings With Children With Autism, Mark P. Groskreutz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Behavioral momentum theory proposes that the persistence of behavior when exposed to disruptors provides an appropriate measure of the strength of behavior. Basic research has consistently demonstrated that behaviors that occurred in a context with higher overall rates of reinforcement (rich contexts) were more persistent than other behaviors that have occurred in a context with relatively lower rates of reinforcement (lean contexts). More surprisingly, behavioral momentum theory goes on to assert that this greater persistence in richer contexts is found even when rate of responding is lower in the rich context, and when the greater richness is due to noncontingent …

Immunophenotyping Of Lymphoid Cells In Autism, L. Jeanne Yonk

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Research into the cause of autism continues without any clear-cut answers. However, recent studies suggest that abnormalities of the immune system are associated with this disorder and autism results from failure of the immune system to regulate itself. Proper immune regulation requires that the host have the appropriate number and percentage of each population of lymphocytes and monocytes. These populations can be distinguished from one another with monoclonal antibodies that react with unique protein structures on the cell surface designated as the "cluster of differentiation" (CD) antigens.

This investigation studied the possibility that the immune abnormalities seen in autism are …
