Maternal Immune Activation (Mia) In Mice: A Study To Phenotype Asd-Related Communication Behaviors And Analyze Maternal Health Outcomes In The Us, Komalpreet Gulati

Honors Scholar Theses

Core symptoms of Autism Spectrum Disorders (ASD) include deficits in social/communicative behaviors, and repetitive/stereotyped behaviors. Mouse models are a highly established paradigm used to study the phenotypic deficits that result from various inducible genotypic or environmental risk factors for ASD. Previous studies have demonstrated a link between maternal immune activation (MIA) and ASD-like behaviors in mouse models. In this model, the maternal immune system is activated during pregnancy by injecting the viral mimic poly(I:C). The resulting offspring are phenotyped and analyzed with regards to their communicative behaviors.

Previous studies have demonstrated that male pups born to dams with immune activation …

Autism And Communication: A Phenomenology Of Parents’ Perspectives, Zoe Sargent

Senior Honors Theses

Autism spectrum disorders (ASD) are characterized by language impairments and are often treated with a variety of communication interventions. In addition to these interventions, the parents of autistic children have to learn how to care for and communicate with their children on a daily basis, especially when their children do not speak. This study made use of phenomenological investigation techniques to explore (1) what parents understand about communication with their nonspeaking autistic children and (2) what particular strategies they find to be effective. Six mothers of autistic children were interviewed, and resulting themes were divided according to parents’ understandings and …

Gray Space And Green Space Proximity Associated With Higher Anxiety In Youth With Autism, Lincoln R. Lawson, Brian Barger, Scott Ogletree, Julia C. Torquati, Steven Rosenberg, Cassandra Johnson Gaither, Jodie Marie Bartz, Andrew Gardner, Eric Moody, Anne R. Schutte

Department of Child, Youth, and Family Studies: Faculty Publications

This study used ZIP code level data on children's health (National Survey of Children's Health, 2012) and land cover (National Land Cover Database, 2011) from across the United States to investigate connections between proximity to green space (tree canopy), gray space (impervious surfaces), and expression of a critical co-morbid condition, anxiety, in three groups of youth: children diagnosed with autism spectrum disorder (ASD, n=1501), non-ASD children with special healthcare needs (CSHCN, n=15,776), and typically developing children (n=53,650). Both impervious surface coverage and tree canopy coverage increased the risk of severe anxiety in youth with autism, but not CSHCN or typical …

An Efficiency Evaluation Of Procedures To Evoke Vocalizations In Children With Autism, Alejandro Rene Diaz

FIU Electronic Theses and Dissertations

Development of vocalizations in early learners with autism is critical to the acquisition of verbal behavior and other important life skills. The purpose of the present studies was to (1) evaluate the efficiency and efficacy of Stimulus-Stimulus Pairing (SSP) and standard Echoic Training (ET) procedures for the development and onset of verbal behavior in early learners with ASD to improve early intervention efficiency and (2) elucidate predictive characteristics or variables for the effective use of SSP. The present studies were comprised of a multiple-baseline (across behaviors) experimental design buttressed within a reversal design, also known more broadly as within-subject controlled …

Teaching Matching-To-Sample To Low-Performing Children With Autism, Blaire E. Michelin

Dissertations

Matching-to-sample is a basic procedure used in most programs for pre-school children with autism. However, a few children fail to acquire this skill with standard matching-to-sample procedures. Therefore, the purpose of this study was to evaluate an alternative method for teaching matching-to-sample to those children when the traditional methods are likely to fail. First, simple discriminations with the matching materials were taught, then the discriminations were made more complex across successive sessions. Initially, all discriminations were taught using bins to separate the comparison stimuli. All three children acquired matching-to-sample, which generalized to matching novel two-dimensional stimuli, not placed in bins.

Examining An Asynchronous Group Discussion Board Adaptation Of A Parent-Mediated Behavior Intervention For Children With Autism Spectrum Disorders, Alexis D. Rodgers

Theses and Dissertations--Educational, School, and Counseling Psychology

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by social and communication deficits, as well as restricted, repetitive, and stereotyped behaviors, interests, and activities (American Psychiatric Association, 2013). Although important relationships have been shown and described among the issues of challenging behavior, parent stress, and parenting sense of competence for families of children with ASD, there is a shortage of intervention programs appropriately suited for families which target these issues. Some programs have been developed and tested, but none is directly applicable for the target population. This is notable because of the connections drawn in the literature between families …

Personal Meanings Of Restricted And Repetitive Behaviors Among Midlife Adults With Asperger Syndrome, Leila Marie Shirley

Walden Dissertations and Doctoral Studies

Restricted and repetitive behaviors (RRBs) are some of the hallmark features of autism spectrum disorder (ASD) symptomatology. There is a knowledge gap on RRBs in adults with ASD because most of the research has focused on children and adolescents. The few studies conducted on adults with ASD have included conflicting results and variable information, especially regarding the developmental trajectories of RRBs. Therefore, this study was designed to address the lived experiences of RRBs in midlife adults with Asperger syndrome. This study was guided by the conceptual frameworks of Dunn's model of sensory processing, the 2-factor model of RRBs, and phenomenological …
