Using audio script fading and multiple-exemplar training to increase vocal interactions in children with autism

Evaluating the Cool Versus Not Cool Procedure via Telehealth

Autistics/individuals diagnosed with autism spectrum disorder (ASD) commonly display qualitative impairments in social behavior that commonly result in the use of interventions directly targeting the development of social skills. The COVID-19 pandemic has highlighted the need for effective social skills interventions that can be delivered directly via telehealth. The Cool Versus Not Cool procedure has continually been documented as effective within the literature. However, its reported use has been limited to in-person delivery. The purpose of this study was to evaluate the effectiveness of the Cool Versus Not Cool procedure conducted via telehealth to teach three children diagnosed with ASD to change the conversation when someone is bored. The results of a nonconcurrent multiple-baseline across-participants design demonstrated that all three participants reached the mastery criterion in four to eight sessions. Responding generalized to another adult for two of the three participants, and all three participants maintained correct responding. Social validity measures indicated the skill was important to teach, the intervention was acceptable and effective, and the telehealth format was an acceptable replacement for in-person intervention for these three participants.

Increasing Verbal Interaction in Children with Autism Spectrum Disorders Using Audio Script Procedure

This study aimed at investigating the effectiveness of audio script and script-fading procedure in teaching initiation to children with ASD. Three children with ASD and a parent of each child participated in the study. A nonconcurrent multiple baseline design across children was used. The findings showed that the initiation emitted by the children increased during audio script and script-fading procedure. Children also generalized initiation across different conditions and maintained the acquired skills. Finally, the social validity findings showed that the opinions of the parents regarding the procedure were overall positive. Results were discussed in terms of recommendations for practitioners and future research.

The importance of multiple exemplar instruction in the establishment of novel verbal behavior

According to traditional linguistic accounts language, and its generative nature, cannot be taught. From a behavior analytic perspective, language is like any other behavior; it is learned and amenable to change. Based upon Skinner's radical behavioral analysis of verbal behavior, specific procedures have been designed to promote novel verbal relations. However, despite the strength and utility of this approach, using behavioral principles to understand the generativity of language has been challenging. Dependent upon the specific theory (e.g., stimulus equivalence, relational frame theory, bidirectional naming) within the radical behavioral orientation, researchers arrange unique procedures to evaluate the variables responsible for this phenomenon. This paper presents the commonalities and differences of two procedures (i.e., multiple exemplar training, multiple exemplar instruction) with examples of research highlighting the use of both in producing generativity. Further, it describes how multiple exemplar instruction is independent from other procedures leading to this outcome, and concludes by providing recommendations for both research and practice.

Establishing a Generalized Repertoire of Initiating Bids for Joint Attention in Children with Autism

The current study evaluated whether multiple-exemplar training, auditory scripts, and script-fading procedures could establish a generalized repertoire of initiating bids for joint attention in four young children with autism. Stimuli drawn from each of three experimenter-defined categories were used during teaching to program for generalization of initiations of bids for joint attention from trained stimuli to novel stimuli. A fourth category was reserved for assessment of across-category generalization of bids for joint attention. The four categories were (a) visually enticing toys, (b) unusually placed items, (c) environmental sounds, and (d) pictures. Assignment of categories for teaching and assessment of generalization was counterbalanced across the participants. Three different auditory scripts were used during intervention for each of the training stimuli to program for response generalization. All four children learned to initiate bids for joint attention. After scripts were subsequently faded and reinforcement was thinned, bids for joint attention were maintained and also generalized to novel stimuli and settings.

Script fading for children with autism: Generalization of social initiation skills from school to home

We used a script-fading package to teach children with autism to initiate social interactions across various activities in the school setting, and we programmed for generalization in the untrained home setting with a sibling. The three participants, ages 8 to 10 years, demonstrated deficits in social initiations with their peers. During baseline, the participants emitted initiations to one another, although this behavior was variable and did not endure over time. With the introduction of the script-fading package, however, social initiations systematically increased. Moreover, the effects of the script-fading package generalized to the untrained home setting with a sibling. This study expands upon previous research by demonstrating the generalization of social initiations from school with peers to the home setting with siblings.
