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 …

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 …

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.

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.

Effects Of Generalized Imitation Training On Functional Speech Acquisition During Picture Exchange Communication System (Pecs) Training, Mindy K. Newhouse-Oisten

Dissertations

The current literature regarding the Picture Exchange Communication System (PECS) demonstrates that some individuals diagnosed with autism acquire speech or gain increases in speech during PECS training; however, the current research base has several limitations. There is a lack of research regarding possible explanations for those speech gains, including possible pre-requisite skills for speech acquisition or procedures that can account for speech acquisition. Some research suggests a link between imitation (both motor and vocal) and language acquisition. The current study examined whether individuals with a generalized motor imitative repertoire are more likely to develop speech during PECS training than individuals …

Application Of Response-To-Intervention In A Pre-Kindergarten Special Education Classroom, Justin J. Daigle

Dissertations

Lovaas (1987) applied behavior analysis to the treatment of autism and demonstrated a 47% “recovery” rate. He also reported that around 10% of the population that received his services made little-to-no improvement. The present study used a response-to-intervention framework to systematically identify and treat students in an early childhood, special-education classroom who were in danger of falling within that 10%. This study set out to identify, classify, and differentiate the treatment based on the student’s response to the standard classroom intervention. Improvements in multiple students’ rates of acquisition based on this system were recorded. This indicated a possibility of improved …

Web-Based Stimulus Preference Assessment And Reinforcer Assessments For Videos, Hugo Curiel

Dissertations

Stimulus preference assessments and reinforcer assessments are integral components of positive reinforcement-based interventions. Web-based brief multiple-stimulus without replacement (MSWO) preference assessments have recently been shown to be effective in identifying preference hierarchies for videos (Curiel, Curiel, Li, Deochand, & Poling, 2018). The purpose of the current studies was to replicate Curiel et al.’s web-based MSWO assessment and assess the reinforcing function of the highest and lowest identified stimuli using novel web-based reinforcer assessments. Study 1 employed single-operant arrangements (SOAs) and Study 2 employed concurrent-operants arrangements (COAs) to assess the absolute and relative reinforcing function of the identified stimuli, respectively. The …

Teaching Students Who Have Difficulty Mastering Lmitation, Jennifer Mrljak

Dissertations

Some children with autism are unable to acquire imitation despite receiving early intensive behavioral intervention (EIBI) meant to teach that and other important skills. Many EIBI programs use physical-prompting hierarchies either as a component of the discriminative stimulus or the correction procedure following an error (Lovaas, 1981; Maurice, Green, & Luce, 1996). But even after lengthy exposure to these teaching techniques, some children still do not acquire imitative repertoires. In the present study, working with students who were not acquiring imitative repertoires, we started with shaping the initial imitative responses as a method to gain stimulus control and then introduced …

Assessing The Effects Of Interactive Video Modeling On The Fidelity Of Implementation Of Skill-Acquisition Procedures, Steven Sparks

Dissertations

Behavior-analytic study has led to many advances in staff training over the last several decades. The effectiveness of modeling, role-play, and video modeling are well demonstrated in scientific literature but these techniques are often time consuming for those conducting the training which often leads to their being quite costly. Interactive video modeling is an alternative that is potentially more cost and time efficient. This type of modeling consists of embedding response opportunities in traditional video models that require the trainee to answer questions in order to complete the video. Being required to answer the embedded questions causes the trainee to …

Transitioning Children With Autism From One-On-One Discrete-Trial Settings To Special Education Classrooms, Jennifer L. Freeman

Dissertations

The goal of an early intensive behavioral intervention (EIBI) program is to teach each child the skills necessary to make meaningful progress in less-restrictive environments (Fox, Dunlap & Crushing, 2002). However, few studies have detailed the steps necessary for a “successful” transition into these educational settings. We transitioned two children, who received 20 hours a week of one-on-one discrete-trial therapy and attended a half-day special education pre-school classroom, to a full-time educational setting. With the goal of aiding each during his/her transition, this study used the Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP) (Sundberg, 2008), particularly the barriers and …

Increasing Vocal Behavior And Establishing Echoic Stimulus Control In Children With Autism, Joseph Shane

Dissertations

Many children with autism fail to demonstrate vocal-verbal behavior, including echoic behavior, as early as their typically developing peers. Some also make very limited vocal sounds in general, remaining mostly mute aside from crying or engaging in stereotypy. Echoic behavior involves auditory discrimination and matching, and functions as a beneficial, if not necessary, prerequisite for many other vocal-verbal skills. The purpose of this study was to develop and implement an echoic training procedure for primarily non-vocal children who did not demonstrate auditory discrimination in baseline. The intervention consisted initially of sessions in which any vocal sounds were reinforced. Then differential …

Teaching Children Who Have Difficulty Mastering Auditory Discriminations, Sarah Lichtenberger

Dissertations

Simple and conditional visual and auditory discrimination repertoires are critical components of many skills necessary for daily functioning, including communication, academic, and daily-living skills (Green, 2001). When auditory discrimination is not under instructional stimulus control, it can result in delayed acquisition of new skills and limit academic progress. The purpose of this study was to teach auditory discrimination to children with autism who had little to no progress on classroom procedures that required auditory discrimination, such as selecting an object from an array when given the name of the object as the direction. Auditory discrimination was taught starting with teaching …

Assessing The Effectiveness Of A Picture Exchange Communication System On Increasing Manding And Vocal Speech In Identical Twin Adults With Autism, Laura C. Hilton

Dissertations

This study examined the effectiveness of a Picture Exchange Communication System (PECS) on increasing manding (i.e., making requests) and spontaneous vocalizations. Participants were a set of identical twin adult women, both with a diagnosis of autism. The main dependent variable was the number of mands emitted by the participants while utilizing PECS. During each phase of training, participants had to meet a specific criterion before receiving a preferred item. Once the participants met the criterion for each phase of PECS training, a new phase began. Spontaneous vocalizations were tracked during each phase of training to determine if, as previous studies …

An Attempt To Establish Approval As A Learned Reinforcer, Kelly T. Kohler

Dissertations

Approval does not function as a powerful reinforcer for many children with autism, making it difficult to reinforce appropriate behavior in a functional and consistent manner. The current study first assessed the effects of establishing approval (“Nice,” accompanied by a smile and nod) and nonsense words as discriminative stimuli, with the intent that they might also become learned reinforcers. We conducted several experiments to assess the effectiveness of approval as a reinforcer, including tests on learning new responses (receptive, expressive, freeoperant, and simple simultaneous discriminations) and tests on the performance of previously mastered responses (receptive and expressive responses). Despite the …
