Teaching Children with Autism to Identify Known and Unknown Information across Self and Others.

This study evaluated procedures for teaching three children diagnosed with autism spectrum disorder the perspective-taking skill of identifying known and unknown information by others based on what they were sensing across all five senses: see, taste, feel, hear, and smell. Using a multiple baseline across participants design, this study evaluated a training package consisting of rules, multiple exemplar training, error correction, and reinforcement. The treatment package successfully taught participants to identify known/unknown information based on what individuals sensed. Generalization across untrained stimuli and people was observed from baseline to posttraining for all participants.

Comparing In-View to Out-of-View Stimulus Arrangements When Teaching Receptive Labels for Children Diagnosed With Autism Spectrum Disorder.

One common best practice recommendation for teaching receptive labels to individuals diagnosed with autism spectrum disorder is for the stimulus array to be arranged outside of the view of the learner. Another strategy that may have benefits would be to arrange the stimuli in view of the learner. The purpose of this study was to compare the relative effectiveness and efficiency of arranging the stimulus array in view versus out of view of the learner when teaching receptive labels to three children diagnosed with autism spectrum disorder. The results of an adapted alternating-treatments design demonstrated that both conditions were effective, and all participants reached the mastery criterion on all training sets. However, the in-view condition was more, or equally, efficient with respect to sessions to mastery when compared to the out-of-view condition. The results are discussed with respect to clinical and research implications for best practice recommendations related to teaching receptive language.

Toward Efficiency and Effectiveness: Comparing Equivalence-based Instruction to Progressive Discrete Trial Teaching.

Research has found equivalence-based instruction (EBI) to be effective and efficient, with recent research extending these finding to individuals diagnosed with autism spectrum disorder (ASD). EBI has also been compared with more traditional approaches to teaching, such as traditional lectures, reading assignments, and video lectures. However, the authors are unaware of any comparisons of EBI to other similar behavior analytic approaches such as discrete trial teaching (DTT). The purpose of the first experiment was to compare EBI to progressive DTT using an adapted alternating treatments design with typically developing adults. Experiment 2 compared the two teaching methods with children diagnosed with ASD. The teaching approaches were evaluated with respect to mastery of trained relations, emergence of untrained relations for the EBI condition, and participant preferences. Results of the two experiments found that both teaching methods were effective, progressive DTT was found to be more efficient for six participants, EBI was found to be more efficient for two participants, and overall progressive DTT was found to be more preferred by participants.

Advances in Our Understanding of Behavioral Intervention: 1980 to 2020 for Individuals Diagnosed with Autism Spectrum Disorder.

There are three branches of science of behavior analysis [i.e., experimental analysis of behavior, behavior analysis, and applied behavior analysis (ABA)]. ABA can be defined as a systematic approach to understanding behavior of social interest. For the past 40 plus years, researchers have evaluated ABA and ABA based procedures (e.g., behavioral intervention) as they relate to individuals diagnosed with autism spectrum disorder (ASD) and have implemented behavioral intervention in clinical settings for individuals diagnosed with ASD. In this paper, we discuss some of the pivotal contributions in the field of ABA in research and clinical practice. Additionally, we provide recommendations for the science and clinical practice of behavioral intervention in the next 40 years.

The Importance of Professional Discourse for the Continual Advancement of Practice Standards: The RBT® as a Case in Point.

The Behavior Analyst Certification Board (BACB®) created a third level of certification, the Registered Behavior Technician™ (RBT®) in 2014. The RBT® was created based upon the requests of stakeholders who wanted to credential those individuals who make direct contact with clients under the supervision of a Board Certified Behavior Analyst®. There has been tremendous growth in the number of RBTs® with over 60,000 individuals certified to date. The BACB® recently sent out a newsletter outlining changes to the RBT® certification, including the processes of training, supervising, and becoming an RBT®. These changes represent a number of potential concerns. The purpose of this paper is to highlight these concerns and to propose solutions to improve the RBT® certification.

Comparing Error Correction to Errorless Learning: A Randomized Clinical Trial.

Errorless learning and error correction procedures are commonly used when teaching tact relations to individuals diagnosed with autism spectrum disorder (ASD). Research has demonstrated the effectiveness of both procedures, as well as compared them. The majority of these studies have been completed through the use of single-subject experimental designs. Evaluating both procedures using a group design may contribute to the literature and help disseminate research related to the behavioral science of language to a larger audience. The purpose of the present study was to compare an errorless learning procedure to an error correction procedure to teach tact relations to 28 individuals diagnosed with ASD through a randomized clinical trial. Several variables were assessed, including the number of stimulus sets with which participants reached the mastery criterion, responding during pre- and postprobes, responding during teaching, efficiency, and the presence of aberrant behavior. The results indicated that both procedures were effective, efficient, and unlikely to evoke aberrant behavior, despite participants in the error correction condition engaging in significantly more independent correct responses and independent incorrect responses.

A randomized clinical trial of three prompting systems to teach tact relations.

Prompts are commonly used during discrete trial teaching for individuals diagnosed with autism spectrum disorder (ASD). Three commonly used prompting systems include constant time delay, most-to-least prompting, and flexible prompt fading. Most of the research demonstrating the effectiveness of these three prompting strategies have been completed through the use of single subject experimental designs. Some within the field of behaviorally based approaches to ASD interventions have called for more randomized clinical trials of these approaches. The purpose of the present study was to compare these 3 prompting systems to teach tact relations for 27 individuals diagnosed with ASD through a randomized clinical trial without a control group with respect to pre-post responding, generalization, sessions to mastery, and responding during teaching. Overall, minimal differences were observed across the 3 systems. The results are discussed with respect to future research and clinical application of the methods evaluated.

A Preliminary Evaluation of a Token System with a Flexible Earning Requirement.

Token systems often involve a predetermined number of tokens required prior to exchange for a terminal reinforcer. The effectiveness of token systems implemented in this manner has been well documented within the literature; however, some have discussed the possibility of a fixed earning requirement creating a context in which the learner no longer emits the desired behavior once the terminal number is achieved. A possible alternative to a fixed earning requirement is selecting the earning requirement based upon learner responding and leaving the requirement unknown to the learner until the moment of exchange. The purpose of this study was to evaluate the effectiveness of a token system with a flexible earning requirement to increase the frequency of comments during snack for 3 children diagnosed with autism spectrum disorder. The results of a nonconcurrent multiple-baseline design demonstrated the flexible token system was effective at increasing the rate of comments in addition to the cumulative number of novel comments.

An Evaluation of a Behaviorally Based Social Skills Group for Individuals Diagnosed with Autism Spectrum Disorder.

In this study we evaluated a social skills group which employed a progressive applied behavior analysis model for individuals diagnosed with autism spectrum disorder. A randomized control trial was utilized; eight participants were randomly assigned to a treatment group and seven participants were randomly assigned to a waitlist control group. The social skills group consisted of 32, 2 h sessions. Teachers implemented a variety of behaviorally based procedures. A blind evaluator measured participants' behavior immediately prior to intervention, immediately following intervention, and during 16 and 32-week maintenance probes. Results of the study demonstrated that participants made significant improvements with their social behavior (p < .001) following intervention, and the results were maintained up to 32 weeks after intervention had concluded.

The Effects of the Cool Versus Not Cool Procedure to Teach Social Game Play to Individuals Diagnosed with Autism Spectrum Disorder.

This study evaluated the utility of the cool versus not cool procedure for teaching three structured indoor games to eight children diagnosed with autism spectrum disorder (ASD). The study took place as part of a social skills group for individuals diagnosed with ASD, and this study was one component of that group. The cool versus not cool procedure consisted of the teacher demonstrating each game the cool (i.e., appropriate) and not cool (i.e., inappropriate) way and having the participants provide a rationale as to why the demonstration was either cool or not cool. This was followed by giving the participants the opportunity to role-play the game in front of the group. The teachers utilized unprompted performance probes with no programmed reinforcement to create opportunities for the participants to display the targeted behavior (s). A multiple baseline design across behaviors and replicated across participants was utilized. The results indicated that seven of the eight participants mastered each of the games taught.

Evaluation of multiple-alternative prompts during tact training.

This study compared 2 methods of fading prompts while teaching tacts to 3 individuals who had been diagnosed with autism spectrum disorder (ASD). The 1st method involved use of an echoic prompt and prompt fading. The 2nd method involved providing multiple-alternative answers and fading by increasing the difficulty of the discrimination. An adapted alternating-treatments design showed that both procedures were more effective than a no-intervention control condition. Providing multiple alternatives did not increase error rates or teaching time, and better maintenance was shown for tacts taught with the multiple-alternative prompt.

Changing preference from tangible to social activities through an observation procedure.

Individuals with autism spectrum disorder (ASD) have qualitative impairments in social interaction and often prefer food or tangible reinforcement to social reinforcement. Thus, therapists who work with children with ASD often use food or tangible items as reinforcers to increase appropriate behaviors or decrease problem behaviors. The goal of the present study was to shift children's preferences from a highly preferred tangible item to an initially nonpreferred social reinforcer using an observational conditioning procedure. Participants observed a known peer engage in a simple task and select the social reinforcer that was not preferred by the participant. This procedure resulted in a shift of preference toward the social reinforcer by all participants. Maintenance data showed that although the preference change did not maintain for 1 of the participants, it was quickly reestablished with additional observational trials. Results provide further support for the use of observational procedures to alter preferences.
