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 …

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 …

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 …

The Acceptability And Feasibility Of Virtual Parent Acceptance And Commitment Therapy Groups: A Feasibility Study, Abigail Elizabeth Moretti

Theses and Dissertations

Parents of children with autism spectrum disorder (ASD) experience higher rates of anxiety, depression, and poor overall well-being, particularly when their child also engages in challenging behavior (e.g., self-injury, aggression, property destruction). Acceptance and commitment therapy (ACT), which encourages psychological flexibility and attending to the present moment, is particularly suited for this population because parents of children with ASD experience high stress levels and difficulty with adaptive coping. The aim of the current study is to examine the feasibility and acceptability of implementing virtual ACT groups with parents of children with ASD and co-occurring challenging behavior. Participants attended an in-person …

The Effects Of Presession Conditions On Behavior During A Brief Functional Analysis, Dung Haylie Le

Theses and Dissertations

Previous research has demonstrated that patterns of responding during a no-interaction condition of a functional analysis (FA) may predict FA outcomes. Thus, behavior analysts may use an initial no-interaction condition to identify problem behavior maintained by social reinforcement when time and resources are limited. However, in a clinic setting, most functional analyses are conducted in between or immediately after instructional sessions or structured play. Therefore, the proposed study was designed to examine the differential effects of presession conditions of naturally occurring activities (work versus play) at a clinic setting during a modified brief functional analysis. Results showed that presession conditions …

Teaching Children With Autism To Tact Private Events Based On Common Properties, Madisyn Quidort

Theses and Dissertations

Skinner (1957) proposed that people learn to talk about private events in several ways. This study sought to examine the plausibility of one of those mechanisms: common properties. Skinner asserted that children learn tacts for public stimuli through normal interaction with their caregivers. When a child experiences a private stimulus that shares some feature with a previously learned public stimulus, the child generalizes the tact to the private sensation because there is a common property between the two stimuli. Three children with autistic disorder were taught 6 to 9 sensation tacts (e.g., prickly, cozy, tight) depicted in videos (e.g., a …

Predictors Of Emotional Health Across Autistic And Non-Autistic Students' First Semester Of College, Erin E. Mckenney

Theses and Dissertations

The prevention and treatment of mental health concerns, including depression, are significant priorities for autistic adults. While several theories have been proposed to explain the high prevalence of depression in autistic populations, little longitudinal research has been done on potential causal mechanisms. Additional research is needed to explore how proposed contributors to depression from general population research -- namely, negative repetitive thinking, lack of social opportunity, and attributional style -- predict and/or moderate the development of depressive symptoms in autistic individuals. The current study investigates these potential predictors' relationship to internalizing symptoms over the course of college students' first semester. …

Associations Between Child Characteristics And Maternal Mental Health In Families Of Children With Autism, Fragile X Syndrome, And Autism Associated With Fragile X Syndrome, Tiffany Nicole Worley

Theses and Dissertations

The present study examined the association between various child characteristics and maternal mental health concerns in three high-risk groups of mothers ± those of children with non-syndromic autism spectrum disorder (NSASD), mothers of children with fragile X syndrome (FXS), and mothers of children with fragile X syndrome and autism (FXS+ASD). Research has shown that mothers of children with NSASD and FXS are thought to share a degree of genetic vulnerability to mental health concerns it is key to examine the various other factors that may contribute to difficulties within the family system and maternal stress, depression, and anxiety.

Participants for …

A Phenomenological Study Of The Lived Experiences Of Siblings Of Individuals With Autism Spectrum Disorder, Adrielle Benini

Theses and Dissertations

This applied dissertation was designed to better understand the experience of having a sibling with autism spectrum disorder (ASD). Research has historically focused primarily on parents of individuals with ASD and their perceptions of how siblings were impacted; however, there was a lack of adequate research where information was obtained from conducting interviews with the siblings themselves.

The researcher conducted a qualitative study with 10 neurotypical siblings, ages 10 to 17, of individuals with ASD. These siblings were interviewed to explore their individual experiences and perceptions about areas in which they found and needed support. The researcher also utilized demographic …

he purpose of the current study was to evaluate the use of behavior skills training via telehealth to teach job interview skills to emerging adults with ASD. Additionally, the study examined if following intervention, skills were able to generalize to new interviewers. 2 undergraduate and 1 graduate student with ASD participated in the study, and received intervention for 3 behaviors: (1) appropriately answering questions, (2) asking appropriate questions, and (3) engaging in appropriate body language. The current study used a multiple baseline design across behaviors. Results from the study indicated BST via telehealth was effective in teaching job interviews skills. …

Characterizing Anxiety And Physiological Correlates In Preschool Children With Neurodevelopmental Disabilities, Jordan Ezell

Theses and Dissertations

This dissertation is comprised of two original research manuscripts broadly examining anxiety and potential correlates in young children with neurodevelopmental disabilities. The first manuscript assessed cardiac regulation during an auditory startle paradigm in young children (3-6 years old) with autism spectrum disorder (ASD), fragile x syndrome (FXS), and neurotypical peers. The second manuscript utilized a new measure developed to capture anxiety in individuals with ASD in order to assess the rate of typical and atypical anxiety and potential risk factors (ASD severity, sex, cognitive ability) for anxiety in preschool children with ASD contrasted to neurotypical preschool children. Collectively, these two …

Evaluating Matrix Training To Teach Children With Autism To Tact Private Events, Abbi Dell Lee

Theses and Dissertations

The research on teaching tacts has primarily focus on visual stimuli, with relatively little attention to teaching tacts of nonvisual stimuli. The present study extended the literature to different types of tactile stimulation by teaching 2-component tacts of body-part sensation combinations in the presence of tactile stimulation. Multiple objects were used to produce the sensations to encourage generalization. Two additional exemplars for each sensation were probed for generalization to novel objects. The experimenters used matrix training, in which target responses were arranged in such a way as to facilitate recombinative generalization to untrained combinations. We arranged 6 body part targets …

Effects Of Instructive Feedback On Gustatory Relations, Natàlia Arasa Bonavila

Theses and Dissertations

Differentiating tastes is important for safety reasons; being able to discriminate flavors could prevent an individual from eating unsafe items. The association of taste, color, and texture of different foods is important for safety reasons as it provides a base knowledge of safe foods. As some people with autism have problems communicating what they see, hear, touch, feel, or taste, the association of color, texture, and taste will promote healthy choices. Most of the research on tact acquisition has focused on visual stimuli. However, this study attempted to teach children to tact gustatory stimuli and evaluated the effects of instructive …

The Effects Of Training On Parent-Implemented Multiple Stimulus Preference Assessments Without Replacement, Marlene Hernandez Correa

Theses and Dissertations

Many children with autism spectrum disorder (ASD) exhibit restricted interests and communication deficits; hence, identifying potential reinforcers can be challenging. Using multiple stimulus without replacement (MSWO) preference assessments is a practical way for practitioners working with this population to identify potential reinforcers. Previous research has found that inexperienced staff can learn to implement preference assessments using enhanced instructions only (i.e., detailed written information, diagrams, and pictures) without needing feedback (Graff and Karsten, 2012b). However, researchers have yet to examine whether enhanced instructions alone impact other populations' repertoires, such as parents, similarly, or if this training is effective across cultures. Incorporating …

Teaching Individuals To Tact The Intensity Of Sensations, Sandhya Rajagopal

Theses and Dissertations

Healthcare professionals frequently ask individuals to use numerical rating scales to rate their pain intensity; therefore, reporting the intensity of private sensations is an important skill. Yet individuals with autism often have difficulty reporting sensations. Using a multiple baseline design across stimulus sets in the pilot experiment and Experiment 1, a multiple probe design across participants in Experiment 2, and a multiple probe design across stimulus sets in Experiment 3, the present study investigated a method of teaching typically developing adults and children and one child with autism to report the intensity of tactile sensations rough, tight, heavy, and temperature. …

The Effects Of Reinforcer Absence And Availability Of Alternative Activity On Delay Of Gratification In Children With Autism, Hailey Rose Prechtel

Theses and Dissertations

An increase in delay tolerance can help individuals obtain more preferred items, activities, and interactions. There are also many situations in a young child's daily life in which they cannot have immediate access to items, activities, or attention that they might be seeking. This can often lead to problem behavior and a longer time to wait for the desired item. Strategies that increase self-controlled responding may help individuals make choices and respond appropriately to receive a better outcome. This study examined the effects of self-control techniques such as removing an item, and interaction with an alternative activity on a child’s …

Exploring The Relationship Between Emotion Recognition, Autistic Traits, And Alexithymia Traits In College Students, Luis E. Sanchez

Theses and Dissertations

Accurately recognizing and interpreting the emotions of others face, voice, and body language is a crucial component for successfully building good social skills with peers. This study explores emotional recognition in individuals with autistic traits, measured by the Autism Spectrum Quotient (AQ), and individuals with alexithymia traits, measured by Toronto Alexithymia Scale-20 (TAS-20). Individuals are presented with various complex emotions using Genova Emotion Recognition Short version (GERT-S). This present study examines the relationship between AQ and TAS-20 and determine if there is any interaction between them for emotional recognition. The researcher found that there was a negative correlation between autistic …

Effect Of A Swim-Based Parent Training Program On A Parent’S Use Of Evidence-Based Strategies With Her Child With Autism, Melissa Lauren Jeffay

Theses and Dissertations

Community participation, particularly in leisure/recreational activities such as swimming, can improve quality of life for children with autism spectrum disorder (ASD). However, youth with ASD generally participate in fewer leisure activities than those without ASD. Although previous studies have demonstrated the benefits of parent training interventions and swim programs for children with ASD, there is a lack of research examining the effectiveness of using parents as intervention agents to teach swim skills to their children with ASD. In this single-case study, the researcher delivered an individual parent training program to the mother of a child with ASD to investigate its …

Cognitive-Behavioral Therapy For Anxiety In Youth With Autism: Paving The Way To Evidence-Based Practice, Michelle M. Kirkland

Theses and Dissertations

Anxiety is one of the most common and debilitating conditions co-occurring with autism spectrum disorder (ASD) as it occurs in up to 84% of individuals and can influence poor psychosocial adjustment, disruptions in individual, familial and school functioning, increased emotional and behavioral problems, self-injurious behavior(s), and an overall reduced quality of life (Meyer, Mundy, Van Hecke, & Durocher, 2006; Nadeau et al., 2011; Farrugia & Hudson, 2006; Kerns et al., 2015). To date, cognitive-behavioral therapy (CBT), an evidence-based treatment for anxiety in neurotypical youth, has seen modest, yet limited, promise in treating anxiety in youth with ASD. With extant research …

Response Interruption And Redirection (Rird) As A Treatment For Vocal Stereotypy In Children Who Are Dually Diagnosed With Autism And Down Syndrome, Stacy Taylor

Theses and Dissertations

Individuals who are dually diagnosed with Down Syndrome (DS) and autism spectrum disorders (ASD) frequently engage in vocal stereotypy that can interfere with learning, impede socially appropriate behavior, and disrupt others. Response interruption and redirection (RIRD) is an intervention that blocks and redirects stereotypy to reduce behavior. Studies on RIRD, while varied in their overall approach, have overwhelmingly been shown to be effective in clinical settings for children with ASD. There are few studies that have evaluated this procedure in more natural settings and with other diagnoses. Given that ASD is prevalent in those with DS and that stereotypy is …

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 …

An Exploration Of Task Independence For High School Students In A Self-Contained Classroom Using Structured Work Systems, Lorinda Rene Otto

Theses and Dissertations

This study investigated the effects of a method to support higher levels of independent performance and generalization of skills using a structured work system with a visual schedule when teaching online task completion skills to high school students with ASD and intellectual disabilities. Students with ASD and intellectual disabilities are typically deficient in independent skills. They often struggle to initiate and complete tasks on their own. By learning to complete tasks independently, high school students with ASD and intellectual disabilities gain essential life skills needed for employment. Structured work systems, along with visual schedules, have shown to be useful in …

A Quantitative Analysis Of Errors During Conditional Discriminations: Changing Sample-Stimuli Disparity In Delayed Matching-To-Sample Task With Children Diagnosed With Autism Spectrum Disorder, Tiara Rahadian Putri

Theses and Dissertations

Conditional discrimination skill is foundational in teaching many other functional skills in children diagnosed with Autism Spectrum Disorder (ASD) and error occur during training. Antecedent- and consequence-based intervention are commonly used without the understanding of underlying behavioral mechanism responsible for these errors. A quantitative framework based on choice- and signal-detection analyses (Davison & Tustin, 1978) was used to quantify and categorize errors. Three children diagnosed with ASD participated. The current study used an automated 0-s delayed matching-to-sample (DMTS) procedure on an iPad Pro® 9.7”. Four experimental conditions were arranged successively, wherein each corresponded with a level of sample stimuli disparity: …

Predicting Change In Autism Symptomatology In Young Children At Risk For Autism Spectrum Disorder: Fragile X Syndrome, Down Syndrome And Non-Syndromic Asd, Kelly Elizabeth Caravella

Theses and Dissertations

This dissertation is comprised of two manuscripts which examine the longitudinal development of autism symptomatology in young children at risk for developing autism spectrum disorder (ASD); individuals with Fragile x syndrome (FXS) and Down syndrome (DS). The first study is a within group analysis of the longitudinal development of ASD symptomatology in young children with FXS, and how diagnostic stability, language and non-verbal cognitive functioning may predict these trajectories. This paper provides insight into ASD diagnostic stability patterns within FXS, and how symptoms change over time across these groups. The second paper will extend this work by presenting a pilot …

"Camouflaging" In Women With Autistic Traits: Measures, Mechanisms, And Mental Health Implications, Jonathan S. Beck

Theses and Dissertations

Autistic traits are associated with frequent psychological distress and everyday functional challenges. Some individuals with autistic traits “camouflage” these traits during social interactions by effortfully engaging in “typical” social behaviors. Camouflaging seems to be especially common in autistic girls and women. Emerging evidence proposes a role for camouflaging behaviors in poorer mental health and daily functioning. Furthermore, camouflaging efforts may delay receipt of a proper diagnosis and access to appropriate mental health care. Despite their clinical significance, camouflaging efforts remain difficult to quantify, and the mechanisms and impacts of camouflaging are poorly understood. This study aimed to compare multiple methods …

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 …

Joint Attention And Imitation: How Early Social Skills Relate To Language, Social Behavior, And Overall Responsiveness To Early Intervention In Children With Autism, Claire E. Karlen

Theses and Dissertations

Joint attention, the ability to coordinate one’s attention with that of another person (Dawson et al., 2004), and imitation, the ability to copy another person’s behavior (Sevlever & Gillis, 2010), are two of the initial methods by which children learn from and interact with the world around them (Trevarthan, 1979). These two skills are related to the development of language, social skills, and play. Further, they seem to come naturally in typically developing children. For children with autism spectrum disorder (ASD), however, these skills are often delayed or entirely absent, thereby potentially leading to significant impediments in the acquisition of …

Training Caregivers To Implement A Structured Meal Protocol To Decrease Food Selectivity Among Young Children With Autism, Ronald Joseph Clark

Theses and Dissertations

This study evaluated a method of training caregivers to implement the Structured Meal protocol to treat children with autism who exhibit food selectivity. A treatment package consisting of written instructions and video modeling as well as in-vivo prompting and feedback (when necessary) was used to teach participants to conduct the protocol. A multiple baseline design across participants was used to evaluate the effects of training. In addition to the primary dependent variable (i.e., correct caregiver implementation of the Structured Meal protocol), data on three secondary dependent variables (i.e., child bite acceptance, mouth cleans, and inappropriate mealtime behavior) were collected. Results …

Discrimination Training To Produce Emergent Relations Of Pre-Algebraic Math Skills, Jeanine Rinda Tanz

Theses and Dissertations

Individuals diagnosed with Autism Spectrum Disorder (ASD) often have deficits with respect to generalization of skills. Procedures designed to induce stimulus equivalence have been shown to promote generalization. This study used a modified multiple probe design with an embedded multiple schedule to: (a) compare one-to-many (OTM) and many-to-one (MTO) training structures to determine which structure results in more positive equivalence outcomes when all variables are held constant, and (b) determine the extent to which children with ASD demonstrate stimulus equivalence and stimulus class mergers when using educationally relevant stimuli. Four children with ASD were taught two classes of stimuli (Class …
