Increasing Novel Vocalizations For Individuals With Asd Using A Voice Output Communication Aide, Shawn Kathleen Bishop May 2017

Increasing Novel Vocalizations For Individuals With Asd Using A Voice Output Communication Aide, Shawn Kathleen Bishop

Master's Theses

This study aimed to extend the literature on VOCA as a means of producing increased verbal speech using a prompt delay and shaping methods. Intervention targeted novel vocalization for three children with autism spectrum disorder (ASD) and limited vocal speech. All three participants increased vocalizations, but to varying degrees and only after a second phase where an echoic prompt was introduced. While the results vary across participants, increased vocal speech for all participants and high social validity suggest that VOCA-based interventions may be an appropriate intervention to increase vocal output for children with ASD.


Descriptive Analysis Of Activity Transition Data In An Intensive Autism Treatment Center, Ashley Marie Kotsiris Jun 2016

Descriptive Analysis Of Activity Transition Data In An Intensive Autism Treatment Center, Ashley Marie Kotsiris

Master's Theses

Children with autism often display challenging behaviors (e.g., tantrums, aggression, etc.) when transitioning between activities. Most of the current literature focuses on antecedent interventions for increasing compliance during transitions (e.g., visual schedules, two minute transition warnings, etc.). There is a minimal number of studies examining how environmental variables may affect transitions. This study was a descriptive analysis that examined different environmental variables and their effects on transitions. Observations were conducted with four children diagnosed with autism. A transition-tracking sheet was used to gather specific descriptive data during transitions. Results suggest that two-minute warnings were not correlated with more ...


The Effects Of Electronic Data Collection, Immediate Graphic Feedback, And Automated Scheduled Prompts On Data Collection Adherence, Cody Morris Jun 2016

The Effects Of Electronic Data Collection, Immediate Graphic Feedback, And Automated Scheduled Prompts On Data Collection Adherence, Cody Morris

Master's Theses

While data are essential to behavior analysis, collecting the type of data that behavior analysts often require can be a labor-intensive and time-consuming task. There have been many attempts to reduce the amount of time and effort required to collect behavioral data; most research in this area has been focused on computerized or electronic ways to do this (Dixon, 2003). While electronic data collection seems to be gaining popularity within applied behavior analysis, many obstacles still exist. The purpose of this project was to design a data collection system that is cost-efficient, adaptable, easy to use, and effective at increasing ...


Development And Validation Of A Survey Of Knowledge Of Autism Spectrum Disorder, Laura Katherine Hansen Dec 2015

Development And Validation Of A Survey Of Knowledge Of Autism Spectrum Disorder, Laura Katherine Hansen

Master's Theses

As autism spectrum disorder (ASD) is more commonly diagnosed, having knowledge of the disorder becomes increasingly important for educators, parents, and the general public. Previous research regarding knowledge of ASD, focused mainly on knowledge possessed by those in the educational field, has found that individuals may perceive themselves as possessing average knowledge regarding ASD but have low actual knowledge (as defined by the researchers) regarding specific aspects of the disorder (Williams et al., 2011). Studies support the notion that there is a general lack of knowledge of different aspects of ASD among teachers; however, there has been little research regarding ...


Age And Iq As Potential Moderators In The Relation Among Endopheonotypes And Expressed Behaviors In Children With Autism Spectrum Disorder, Elizabeth Clara Fair May 2015

Age And Iq As Potential Moderators In The Relation Among Endopheonotypes And Expressed Behaviors In Children With Autism Spectrum Disorder, Elizabeth Clara Fair

Master's Theses

The current study examined how certain endophenotypes (i.e., local processing ability, mental flexibility, planning, and disinhibition /inhibition) are related to specific expressed behaviors (i.e., acting out behaviors, social insight deficits, social contact problems, anxious/rigid behaviors, and stereotypical behaviors) that are commonly found in children with ASD. In addition, this study examined whether these associations are modified by age or IQ. Participants consisted of 29 children (ages 7 to 16 years) with ASD and their parents. Parents completed the Children’s Social Behavior Questionnaire (CSBQ) to assess their child’s variety of expressed behaviors. The children were given ...


A Comparison Of Two Variations Of A Stimulus-Stimulus Pairing Procedure On Novel And Infrequent Vocalizations Of Children With Autism, Andrew J. Bulla Aug 2014

A Comparison Of Two Variations Of A Stimulus-Stimulus Pairing Procedure On Novel And Infrequent Vocalizations Of Children With Autism, Andrew J. Bulla

Master's Theses

Despite the growth in a behavioral technology for the treatment of autism, a small population of individuals with autism fails to develop functional language. One procedure used for inducing vocalizations in non-verbal children is a stimulus-stimulus pairing (SSP) procedure. In an SSP procedure a vocalization is paired with a reinforcer over a period of time to establish the vocalization as a learned reinforcer, and any utterance of the target vocalization is believed to be automatically reinforced thus increasing the frequency of the vocalization. Past research has yielded mixed results with the SSP procedure, and more research is warranted to identify ...


The Gender Of Participants In Published Research Involving People With Autism Spectrum Disorders, Erin Watkins Apr 2014

The Gender Of Participants In Published Research Involving People With Autism Spectrum Disorders, Erin Watkins

Master's Theses

Research articles involving participants with an autism spectrum disorder and published from 2010-2012 in Autism, Journal of Autism and Developmental Disorders, Journal of Child Psychology and Child Psychiatry, and Research in Autism Spectrum Disorders were examined to determine the reported gender of participants. The overall male:female ratio was 4.62, which is similar to that reported in epidemiological studies, but the ratio was 6.07 in intervention studies. These findings suggesting that males were in a statistical sense over-represented in intervention studies, but not in other kinds of research. Most (82.21%) of these studies included both male and ...


Intact Statistical Word Learning In Autism Spectrum Disorders, Jessica Mayo Aug 2011

Intact Statistical Word Learning In Autism Spectrum Disorders, Jessica Mayo

Master's Theses

Individuals with Autism Spectrum Disorders (ASD) have impairments in language acquisition, but the underlying mechanism of these deficits is poorly understood. Implicit learning appears potentially relevant to language development, particularly in speech segmentation, which relies on sensitivity to the transitional probabilities between speech sounds. This study aimed to investigate the relationship between implicit learning and current language abilities in school-aged children with autism (n = 17) and typical development (n = 24) using a well-studied artificial language learning task. Results suggest that the ASD and TD groups were equally able to implicitly learn transitional probabilities from a lengthy stimulus stream. Furthermore, task ...
