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.

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.
