In this study, we examine the effects of video modeling to teach complex emotions across seven children diagnosed with autism. Each participant was shown five short video clips and identified characteristics such as, body language, facial expression, voice, and volume. The results suggest that video modeling can quickly promote skill acquisition in identifying complex emotions across all participants.

Children with autism spectrum disorder (ASD) often show motor stereotypies that could represent barriers to learn functional behaviours. Some studies showed that antecedent exercise (AE), a procedure based on physical activity, can effectively decrease the rate of motor stereotypies. One study in particular applied AE through an indoor elliptical bike in a home setting. The aim of the present study is to replicate this finding on AE in a center-based intervention. One 6 years old child with ASD, male, participated in the study. The procedures involved fading of the prompt for the correct jogging position and movements, shaping of the jogging sessions duration and positive reinforcement available at the end of a correct jogging session. The jogging sessions were performed as an AE in order to reduce motor stereotypies. Collected data indicate that AE is successful in decreasing the target behaviours in a center-based intervention. The findings could have important implications for the treatment of motor stereotypies in people with ASD.

Individuals with autism spectrum disorder (ASD) and co-occurring moderate intellectual disability (ID) have deficits in conversations because of challenges in interpreting vocal and nonvocal responses and in identifying appropriate moments to initiate, maintain, or terminate conversations. Our purpose in this study was to increase conversations in three young adults with ASD and co-occurring moderate ID. First, we used an intervention package consisting of Behavior Skills Training (BST) and Covert Audio Coaching (CAC) to promote acquisition and maintenance of conversations with coworkers. Second, we implemented CAC during naturally-occurring opportunities at an internship site. Third, we examined if initiations with coworkers increased during and after participants learned to initiate, maintain, and terminate conversations. We used a concurrent multiple-baseline design across participants with continuous acquisition probes to evaluate the effects of the intervention in producing acquisition and maintenance of conversations and increasing the frequency of initiations. Results demonstrate that the intervention was effective in producing acquisition and maintenance of the target skills in all three young adults. Data also indicate that participants initiated more interactions with coworkers as conversational competence increased.

Deficits in social communication and social interaction are key elements of Autism Spectrum Disorder. Video modeling (VM) has been successful in teaching new skills, particularly social communication skills, through short, targeted videos. However, prior research in VM has heavily focused on academic settings with elementary school age children. There is a gap in the literature on teaching social skills in natural settings to adolescents with ASD. This research used a single- subject, multiple-baseline design to examine the impact of VM on the social behaviors of adolescent males (n=3), diagnosed with ASD, in natural social settings. The dependent variable was scored for responses based on scripted verbalizations included in the video treatment, scripted social actions, and spontaneous reciprocal verbal interactions chains. Visual analysis, percentage of nonoverlapping data points, and effect size were used to evaluate data. In addition, social validity data on acceptability and satisfaction of the intervention were collected. Results indicated large effects for the adolescent participants when interacting socially in community settings and the treatment was found to be socially acceptable by adolescents and by habilitative intervention professionals.

Writing skills are necessary in several circumstances: in school, writing is an indication of content learning; upon graduation people are expected to write in several contexts, from formal office tasks to text messaging on Instagram or Facebook. Besides the difficulties that are reported when teaching writing to any children (e.g., picture-spoken word - written word relations; letter shape discrimination), characteristics linked to Autism Spectrum Disorder (ASD) seem to increase the likelihood of learning issues, such as use of language structure, initiation and termination of discourse, and perseverative comments. There is a scarcity of procedures for teaching writing to children with ASD. The purpose of this study was to systematically review intervention studies, published in peer review journals, that versed on teaching writing to children with ASD. We analyzed previous reviews on the topic and reviewed empirical studies from 2008 through 2018, according to several criteria. Five articles met all criteria, in all four phases, among 393 found. Three writing behaviors, subdivided into several dependent variables, have been targeted for intervention, which always included more than one procedure. Research is still needed to establish best practices for teaching writing to children with ASD.

This systematic review summarizes and analyze the literature on sportsmanship interventions for individuals with autism. Sportsmanship skills are necessary for children to engage in game play with peers, cooperate in team sports, and participate in community leisure activities. Twenty-eight studies were included in this study that used experimental designs (single-case design and group design) that targeted sportsmanship behaviors. The results were summarized across participants, targeted behaviors, settings, interventions, and methodological rigor of the included studies. Different types of outcomes, such as play skills, social skills, and specific sportsmanship skills were targeted in the studies. Various types of behavioral interventions and strategies including group instruction, BST, video modeling, and token economies were implemented to improve sportsmanship behaviors for individuals with autism. Although most studies reported positive outcomes on the targeted social-communication behaviors, methodological limitations should be considered when interpreting the results as 64% of the studies included were of weak methodological rigor. Limitations of this review and implications for future research are discussed.

Animal-assisted interventions (AAI) have become increasingly popular, especially within the field of autism (ASD). Unfortunately, there exists little empirical data on intervention prevalence or its effectiveness. To date, there exists no empirical data examining the use of AAI as an adjunct to ABA services. This study explored animal incorporation practices, perceived intervention desirability/feasibility, level of AAI knowledge and awareness, and perceptions/attitudes concerning AAI among active BACB certificants (RBT, BCaBA, BCBA, and BCBA-D certificants) working within the United States (including Puerto Rico). Participants, recruited via the BACB mass email service, were asked to complete a comprehensive, cross-sectional web-based survey developed with the input of 25 expert reviewers. This poster presents data from the Animal Incorporation Practices portion of the survey. A total of 544 BACB certificants participated in this survey study, of which roughly 20% (n=107) reported physically incorporating animal(s) into ABA services with their clients. Analysis of incorporation practices (e.g., intervention format, purpose of animal incorporation, and data collection procedures), individual animal characteristics (e.g., animal species and level of training), and perceived effectiveness of their practices was conducted. Discussion of these findings and how they relate to the Professional & Ethical Compliance Code and animal welfare considerations were presented.

Past research has shown that response interruption and redirection (RIRD) decreases automatically maintained behaviors such as vocal stereotypy (VS) and in some cases increases appropriate vocalizations. For example, Ahearn et al. (2007) used RIRD to effectively treat vocal stereotypy by presenting vocal demands contingent upon VS. In addition, Ahrens et al. (2011) found that motor demands contingent upon VS were also effective in decreasing VS. The purpose of the current study was to compare the effects of motor RIRD versus vocal RIRD in relation to VS, appropriate vocalizations, compliance with each procedure and social validity measures with children diagnosed with an Autism Spectrum Disorder. Participant 1 had a limited vocal repertoire consisting of sounds and short word utterances. Participant 2 and 3 had established mand and tact repertoires. A reversal design was used to compare the effects of motor and vocal RIRD. During motor RIRD, VS was redirected to motor compliances (e.g. touch your nose, clap your hands). During vocal RIRD, VS was redirected to vocal compliances (e.g., tacting or vocal imitation). IOA was calculate din 33% of all sessions across all participants and averaged 95% overall. Results indicated that both motor RIRD and vocal RIRD produced lower levels of VS for all participants and increased appropriate vocalizations for one participant that had a vocal verbal repertoire. Although the vocal RIRD procedure increased appropriate vocals, the motor RIRD procedure demonstrates the utility of RIRD with individuals who have limited vocal verbal repertoires. In addition, compliance was higher during the motor RIRD condition for all participants. Clinical considerations regarding the effectiveness, preference, and social validity of the two procedures are also discussed.

Individuals with autism spectrum disorder (ASD) experience impairments across a wide range of skill domains, including self-care skills. The ratio of 1:59 children diagnosed with Autism Spectrum Disorder (ASD) all around the world, according to the Centre of Autism Disease Control and Prevention Survey. This makes it a demanding problem to be addressed. Nearly 28 percent of 8-year-olds with ASD have self-injurious behaviors. The childcare and diagnosis available today are very few and generalized that makes the life of an autistic child very difficult. Auticare is an Assistive Technology that gives standard ABA therapy and treatment for high functioning autism and related neurodevelopmental disabilities. The therapy platform in Virtual Reality includes different training scenarios solely based on applied behavior analysis that encourage to develop cognitive, social, self-care skills. Not only does this platform provides therapy but it also helps doctors to diagnose the present condition and judge the progress of autistic children through progressive data stored in the cloud. The product is launched and currently being used for therapy in government hospitals and special education centers. The objectives of the current study were to determine the efficacy of the product Auticare among high functioning autism in improving cognitive, social and self-care skills in centers that have already installed the product. The findings of the product revealed that immersive VR training may be a safe and viable method of teaching basic self-care skills using behaviour analysis. Using a forum for virtual reality provides an effective treatment alternative to enhance commonly found cognitive and social impairments in Autism Spectrum Disorder by providing children more immersive, efficient, safe and engaging experience based on applied behaviour analysis technique.

Children with high functioning Autism Spectrum Disorder (ASD) often engage in repetitive behaviors topographically similar to those seen in Obsessive Compulsive Disorder. A Randomized Controlled Trial (Vause et al., 2018) used a manualized Functional Behavior-based Cognitive Behavior Therapy (Fb-CBT) with 37 children (n = 19 in experimental and n = 18 in Treatment As Usual), and demonstrated significant differences in Obsessive Compulsive Behaviours (OCBs) between groups from pre to post-test, with large effect sizes. Considering the importance of behavioral maintenance, the present study evaluated the long-term treatment outcomes of 13 children, 5 to 7 years following Fb-CBT. The Repetitive Behavior Scale–Revised (Compulsive, Ritualistic, and Sameness subscales; Bodfish et al., 1999) and parent report questionnaires evaluated OCBs from post-treatment to 5-7 year follow-up. Across participants, there were no significant changes in OCBs between post-test and 5 to 7 year follow-up. However, there was some variability in maintenance of treatment gains. A matched-comparison qualitative case study identified factors that may have contributed to the variance across outcomes. Five semi-structured interviews were conducted with 5 parent and 4 child participants whose quantitative results reflected this variance. Thematic analysis identified common themes across and within cases (Braun and Clarke, 2006). Results from the qualitative analysis support the current ABA and CBT literature—that is—parents whose children were more successful in maintaining treatment gains stressed the importance of parent training and support received during Fb-CBT, and continued work on generalization and practice of coping strategies during exposures post-treatment.

Self-advocacy is an important life skill. Individuals with autism spectrum disorder (ASD) may have difficulty self-advocating due to socio-communicative deficits. Other factors related to ASD, such as social anxiety and a dependent lifestyle, may further restrict familiarity with self-advocacy and the ability to self-advocate. Therefore, instruction is often necessary to establish self-advocacy skills to individuals with ASD. Unfortunately, several different definitions of “self-advocacy” exist within self-advocacy literature. Studies have also used different methods to teach self-advocacy and have focused on different target behaviors. Our project aims to propose a comprehensive definition for “self-advocacy” based on commonalities in definitions proposed by previous research and to describe empirically supported methods for teaching self-advocacy to adults with ASD. We collected literature using a set of criteria based on self-advocacy and related terms. Sources were sorted based on whether they defined self-advocacy or sought to teach it, with membership in both groups possible. Ongoing analysis suggests that definitions including self-knowledge, problem recognition, ability to articulate need, and taking initiative are most common, and that behavioral instruction is consistently associated with successful learning of self-advocacy. Areas for future research by applied behavior analysts working with this population are discussed.

This study examined the effectiveness of the Copy, Cover, and Compare (CCC) strategy for English as second language students. This study used the CCC method (Skinner et al., 1997) to increase the percentage of words spelled correctly for two students—a student with autism and a typically developed student. Moreover, the study extended Carter et al. (2013) study by adding maintenance probe and generalization probe. The results of this study are inconclusive between the participants. The data from one participant showed that the CCC alone was not able to increase correct word spelling, maintain, and generalize. On the other hand, the data from another participant revealed the opposite results. Limitations included: no preference assessment conducted, did not collect the percentage of correct letter within words, and did not evaluate the effectiveness of prompt used. Implications and recommendations were discussed in the study.

B.F. Skinner posited in 1981 that culture is one of the three types of selection impacting human behavior, yet Applied Behavior Analysis (ABA) has often overlooked it. As the reach of ABA grows and the recipients of behavior-analytic services become more diverse, it is imperative that the participants in research studies reflect that diversity. Evidence-based practices for autism intervention are being identified by The National Clearinghouse on Autism & Evidence Practice (NCAEP) in their systematic review of the intervention literature published from 2012-2017. The data presented in this poster intends to answer an important follow-up question: For whom are these interventions evidence-based? The single subject design research articles (n=597) identified by NCAEP were reviewed for descriptions of participant race and gender in accordance with the procedure and reliability protocol described by West et al. (2016). The findings indicate that 24.28% (n=145) of the studies report on race. The majority representation was white participants at 55%. Black participants were represented at 16% and Hispanic/Latino participants comprised 12%. The gender composition was 83% male and 17% female with no reports of gender non-binary participants. This indicates that the field needs more reporting on participant demographics and greater diversity in participant ascertainment.

With the increase in autism spectrum disorder (ASD) prevalence, the number of adolescents and adults with ASD is also rapidly increasing, which increases the number of adults with disabilities seeking services. As individuals with ASD grow up, their social-communication issues seem to increase and required in more complex skills. There are critical needs for evaluating the efficacy of communication interventions on more complex language use for this adolescents and adults age ranges to address the most effective and suitable interventions for this population across implementers variables, communicative function variables, and setting variables.The purpose of this meta-analysis is to determine effectiveness of social and communication intervention for adolescents and adults with ASD, primarily discriminated by these variables: interventionists, communicative functions, and setting. We will investigate the social-communication outcomes on each intervention category. The author will include single-case experimental designs (SCEDs) in this meta-analysis.

According to existing literature, the incidence of persistent toe walking is greater in children with an Autism Spectrum Disorder (ASD) diagnosis than in children without a diagnosis. Approximately 20% of children with an ASD diagnosis engage in this motor behavior, often associated with tight heel cords, which can lead to the need for more intrusive medical or even surgical intervention if left untreated. Current literature suggests the use of auditory feedback devices (e.g., GaitSpot™) attached to participants’ feet and differential reinforcement are effective treatments for toe walking; however, additional research should replicate these findings and control for the presence of the auditory feedback devices. In the current study, researchers evaluated multiple components of a toe walking treatment package across two participants with ASD. Components included auditory feedback devices, differential reinforcement for appropriate steps, and a mild physical prompt to place heels on the ground, as needed for each participant. Researchers faded and thinned procedure schedules according to each participants’ performance in order to assess maintenance and improve social validity.

We examined the effects of fluency training across two verbal operants and the collateral effects across untrained verbal operants. The participant was a 6-year old with autism who frequently engaged in long response latencies during instruction. Fluency training was applied to echoics and then to intraverbals within an alternating treatments design. Results showed decreases in the latency to respond (s) in the verbal operants that were exposed to fluency training. Additionally, we observed decreases in the latency to respond in the verbal operants that were not exposed to the training, indicating generalization of the effects across untrained verbal operants. Mean response latencies were at or below 2.3 s across all verbal operants in the final phase. We will discuss the potential benefits of fluency training.

Matrix training is a form of generative instruction that allows the clinician to teach a limited number of targets and obtain the emergence of responding across untaught targets, resulting in faster skill acquisition. Matrix training has been used to teach a range of skills to individuals of varying abilities. Recently, work from our laboratory explored the use of matrix training to expand the verbal behavior repertoire of young children with autism spectrum disorder (ASD). In the present study, the focus was to evaluate whether teaching one operant, motor imitation actions with toys, would result in emergence of untaught actions and untaught operants, tacting and listener responding. In addition, we evaluated whether instructive feedback would facilitate emergent learning. A 4-year old boy with ASD served as participant. Researchers taught motor imitation according to noun-verb combinations from two matrices, A and B, and only trials of matrix A were accompanied by instructive feedback. The diagonal targets of both matrices were readily acquired. Subsequently, researchers conducted probes for each untaught recombinative motor imitation targets and other operants. The effects of instructive feedback to promote emergent learning when using matrix training will be discussed.

Some individuals with ASD may be indifferent to, or avoidant of, social interaction. Evaluating methods of increasing social time allocation are important with this population. We assessed the extent to which three children with ASD would approach or avoid social interactions. During baseline, when subjects were on the same side of the room as a therapist the therapist delivered vocal interaction and when subjects were on the opposite side of the room no interactions were delivered. All three subjects were indifferent or avoidant of social interaction in baseline. During the intervention, the therapist began to initiate each subjects’ preferred interactions. During the intervention, all subjects allocated their time more socially and were more likely to follow the therapist to maintain access to social interaction.

Assessing the function of social interaction is important for individuals with ASD. Some researchers have provided methods of assessing whether social interactions function as reinforcing, neutral, or aversive stimuli for individuals with ASD. However, these methods provide rather coarse measures of the function of social interaction (e.g., reinforcing, neutral, or aversive) and it may be useful to evaluate methods of obtaining more quantitative and precise measures of the function of social interaction. We evaluated the degree to which eight children with ASD were likely to allocate their time near or away from a therapist who delivered social interactions. Across conditions the ratio of time the therapist spent on the left versus right half of the room was manipulated and we evaluated the degree to which the subject’s behavior changed across conditions. This relationship was quantified using a modified version of the power-function matching equation.

Functional Communication Training (FCT) is an evidence-based intervention for students with autism spectrum disorder (ASD). FCT is used to teach students with ASD a functionally equivalent communicative response (FCR) to replace challenging behavior. While there is extensive research on FCT and some even measures generalization of the skills across settings, to date, there are no studies evaluating the effects of FCT implemented in a special education setting and generalization to the general education setting. This is critical, as most students with ASD spend part of their days in a special education setting. In the current poster, presenters will provide data related to FCT implemented in a special education setting and the effects on the generalization of the FCR and challenging behavior to the generalization setting with elementary students with ASD. The presenters will discuss implications for research and practice.

Iwata, Dorsey, Slifer, Bauman, and Richman (1982/1994) proposed an approach to behavioral assessment based on the experimental model that has been largely used in applied settings. In order to conduct a functional analysis of aggressive behavior of severely handicapped clients in an outpatient setting during a 90-min period Northup et al., (1991) proposed a brief functional assessment approach. In this article we compare the outcomes of both functional analysis methodologies to an autistic adolescent with severe aggressive behavior. Results suggested that Iwata, Dorsey, Slifer, Bauman, and Richman (1982/1994) approach was essential to design idiosyncratic conditions that were later confirmed in the brief functional assessment approach.
