Developmental Functioning Of Infants And Toddlers With Autism And Down Syndrome, Celeste Tevis
Developmental Functioning Of Infants And Toddlers With Autism And Down Syndrome, Celeste Tevis
LSU Master's Theses
Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social communication, as well as restricted interests and repetitive behaviors. Approximately 10% of individuals with ASD also have comorbid genetic or chromosomal conditions, like Down Syndrome (DS). While it was once believed that DS and ASD rarely co-occurred, it has been demonstrated that it is not uncommon for children with DS to also meet criteria for ASD. Due to the difficulties in differentiating between impairments associated with intellectual disability (ID) and ASD symptomology, DS often leads to delayed or misdiagnoses of ASD. This can interfere with early intervention …
Characterizing Receptive Vocabulary Knowledge In Minimally Verbal Children With Autism Spectrum Disorder, Allison Menting
Characterizing Receptive Vocabulary Knowledge In Minimally Verbal Children With Autism Spectrum Disorder, Allison Menting
LSU Master's Theses
Background: Delayed or impaired language skills are common characteristics of children with autism spectrum disorder (ASD). Currently, there is little research examining the receptive language profile in children with ASD, and even less is known about children with ASD who are minimally verbal. The current study aimed to characterize the receptive vocabulary profile of minimally verbal children with ASD and to examine whether this profile differs from their typically developing peers. Methods: Participants included 31 minimally verbal children with ASD, aged 60-118 months, who were reported to produce between 0-10 words, 124 typical developing toddlers, aged 9-14 months, who were …
Differences Between The Acoustic Parameters Of Prosody In Speakers With Asd And Typically Developing Speakers Ages Three To Six, Heather Delaune
Differences Between The Acoustic Parameters Of Prosody In Speakers With Asd And Typically Developing Speakers Ages Three To Six, Heather Delaune
LSU Master's Theses
The present study was designed to compare the acoustic parameters of prosody of children between the ages of three and six with Autism Spectrum Disorder (ASD to age matched typically developing (TD) speakers. The acoustic parameters of prosody examined were fundamental frequency (f0), intensity, speech rate, and speech rhythm. Analyzing the acoustic features of atypical expressive prosody in speakers with ASD would provide more detailed and defined information regarding the nature of the prosodic abnormality in these individuals to guide clinicians in providing a more concentrated focus for intervention. Speech samples were obtained from ten English-speaking, monolingual children (5 ASD, …
Change In Developmental Quotient In Toddlers Assessed For Autism Spectrum Disorder, Lindsey Willis Williams
Change In Developmental Quotient In Toddlers Assessed For Autism Spectrum Disorder, Lindsey Willis Williams
LSU Master's Theses
ASD is marked by significant delays in social and language development, while development in other areas, such as cognitive functioning, can be highly variable from person to person. Though preschool-aged children with ASD often exhibit a profile of developmental delays similar to children with other developmental disorders at a discrete moment in time, few studies have investigated possible differences in rate of skill acquisition in developmental domains in children with different disorders. Sensitive periods of development are marked by less stability in performance of developmental skills. Results of prior studies suggest that if appropriate early interventions are applied during sensitive …
The Moderating Effect Of Gender On The Relationship Between Socialization And Internalizing Problems In Early Childhood, Hilary Lynn Adams
The Moderating Effect Of Gender On The Relationship Between Socialization And Internalizing Problems In Early Childhood, Hilary Lynn Adams
LSU Master's Theses
Researchers in the field of Autism Spectrum Disorders (ASD) have confirmed that comorbidities are a common problem among diagnosed individuals. Current estimates suggest that more than two thirds meet criteria for an additional diagnosis of psychopathology. In particular, rates of several internalizing problems (i.e., anxiety, depression) appear to be greater for individuals with ASD than their typically developing counterparts. However, little research has been conducted examining factors apart from autism symptomatology that could influence this prevalence difference. Additionally, it is well established that anxiety and depression are more common in females than males in the general population. However, few studies …
An Examination Of The Relationship Between Communication And Socialization Deficits In Infants And Toddlers With Autism And Pervasive Developmental Disorder-Not Otherwise Specified (Pdd_Nos), Megan Alice Hattier
LSU Master's Theses
Autism Spectrum Disorders (ASDs) are characterized by pervasive impairments in repetitive behaviors or interests, communication, and socialization. As the onset of these features occurs at a very young age, early detection is of the utmost importance. In an attempt to better clarify the behavioral presentation of communication and socialization deficits to aid in early assessment and intervention, impairments in these areas were examined among infants and toddlers (17-37 months) with Autistic Disorder (AD), Pervasive Developmental Disorder – Not Otherwise Specified (PDD-NOS), and non-ASD related developmental delay. The Baby and Infant Screen for Children with aUtIsm Traits-Part1 (BISCUIT-Part1) and the Battelle …
Gender Differences In Core Symptomatology In Autism Spectrum Disorders Across The Lifespan, Tessa Taylor Rivet
Gender Differences In Core Symptomatology In Autism Spectrum Disorders Across The Lifespan, Tessa Taylor Rivet
LSU Doctoral Dissertations
A preponderance of males with autism spectrum disorders (ASD) has been evident since the initial writings on the topic. This male predominance has consistently emerged in all ASD research to date in epidemiological as well as clinical populations. Despite this long recognized gender disparity in ASD, surprisingly there is a paucity of research addressing gender as it relates to core ASD symptom presentation. Gender differences may manifest with regard to symptom domains, severity, breadth, and so forth. The present research examined gender differences in ASD symptomatology in three populations: infants and toddlers at risk for developmental disability, children and adolescents, …
Gender Differences In Children With Autism Spectrum Disorders And Comorbid Psychopathology, Julie Hess
Gender Differences In Children With Autism Spectrum Disorders And Comorbid Psychopathology, Julie Hess
LSU Master's Theses
Abstract Children and adolescents diagnosed with Autism Spectrum Disorders (ASD) frequently exhibit symptoms that are not associated with the core features of ASD. These symptoms may meet criteria for an additional diagnosis; however, accurate assessment of comorbid psychiatric conditions in ASD has been hindered by a lack of measures designed for this specific purpose. The newly constructed assessment measure, Autism Spectrum Disorders-Comorbid for Children (ASD-CC) has been developed specifically for examining comorbid psychiatric disorders in ASD. Therefore, this study set out to assess differences in the endorsement rates of psychiatric symptoms in children and adolescents diagnosed with ASD compared to …

A Comparison Of Morphophonic Faces And The Picture Exchange Communication System On The Production Of Verbal Communication In Preschoolers With Autism, Ashley Nicole Bourque
A Comparison Of Morphophonic Faces And The Picture Exchange Communication System On The Production Of Verbal Communication In Preschoolers With Autism, Ashley Nicole Bourque
LSU Master's Theses
Children with Autism Spectrum Disorder (ASD) exhibit difficulties with both verbal and nonverbal language with approximately 50% of children diagnosed with autism remaining functionally mute into adulthood (Charlop & Haymes, 1994; Charlop-Christy, Carpenter, Le, LeBlanc, & Kellet, 2002). This study explored intervention using the Picture Exchange Communication System (PECS) for two nonverbal preschoolers with ASD. The effects of PECS using two picture systems, Picture and Words (P&W) and MorphoPhonic (MPh) picture word, was assessed in the communicative outcomes after 6 weeks of intervention. This study asked if MPh picture words would elicit more picture-exchange communication acts in functional contexts than …
Deficits In Social Skills And Feeding Behaviors Associated With Adults Diagnosed With Autistic Disorder Living In An Institutionalized Setting, Cindy Terlonge Graham
Deficits In Social Skills And Feeding Behaviors Associated With Adults Diagnosed With Autistic Disorder Living In An Institutionalized Setting, Cindy Terlonge Graham
LSU Master's Theses
Autistic disorder, a syndrome beginning in infancy and persisting into adulthood, has captured the attention of researchers and clinicians alike. Although this disorder has been studied since the mid-1940s, there is a lack of literature addressing certain adaptive skills in adults with autism. The aim of this study was to examine the differences in social and feeding skills between individuals with and without autistic disorder. Given the importance of acquiring these skills to facilitate proper adjustment and decrease potential health risks, better understanding of these behaviors in persons with autism is warranted. Participants comprised three separate groups: an autism group, …
