Accurately Diagnosing Autism Spectrum Disorder Among A Comorbid Population, Michelle Okolita

Dissertations

Two of the most common neurodevelopmental disorders, attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD), are diagnosed in early childhood. The two disorders share similar impairments across domains, are highly comorbid, and have many overlapping symptoms. Studies have shown that among this comorbid population, children receive an ASD diagnosis a few years after their initial ADHD diagnosis, which leads to many negative consequences, including a delay in treatment. The focus in this study was on the early indicators of ASD that are present prior to the age of 3 years in order to educate others on these symptoms. In an …

Establishing Auditory Discrimination And Echoic Stimulus Control With An Auditory Matching Procedure, Clare Christe

Dissertations

A generalized auditory matching repertoire is considered an early milestone in the development of verbal behavior (Greer & Keohane, 2006). Previous literature has demonstrated that the auditory matching (AM) protocol can improve echoics in individuals with developmental delays (Brown, 2005; Choi, Greer & Keohane, 2015; Du, Speckman, Medina, & Cole-Hatchard, 2017). However, some children experience difficulties with the match-to-sample (MTS) format of the AM protocol, if they are unable to perform delayed MTS tasks.

One alternative to MTS is the go/no-go procedure (Serna, Dube, & McIlvane, 1997), which requires the student to make a simple discrimination (i.e., same/different) between two …

Teaching Children With Autism To Make Independent Requests Using An Echoic-To-Mand Procedure, Michael L. Tomak

Dissertations

Mands are a vital skill for the development of a child’s communicative repertoire and are typically a major focus of early intensive behavior interventions (EIBI). Naturalistic teaching is more efficient than Discrete-Trial Training (DTT) for teaching mands (Jennet, Harris, & Delmolino, 2008); and therefore, the present study used crucial components from naturalistic teaching to teach mands in a discrete-trial format, using an echoic-to-mand procedure. This intervention increased the children’s independent vocal requests. Initially, they learned to mand for items in sight and eventually for those out of sight.

Using A Video Modeling Treatment Package To Teach Imitation To Children With Autism, Sofia F. Peters

Dissertations

Imitation is a critical skill that allows individuals to learn through less restrictive prompting methods and may allow access to less restrictive learning environments, such as typical classrooms, where instruction is often delivered by modeling. Many individuals with autism learn to imitate with interventions that utilize live models and least-to-most prompting strategies; but, for some, these methods are not successful or efficient. While video modeling has been used to teach a variety of skills to individuals with autism, there is limited research using video modeling to teach imitation. This study investigated the effectiveness of using a video modeling treatment package …
