RESUMEN
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.
RESUMEN
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.

RESUMEN
For over 50 years, intervention methods informed by the principles of applied behavior analysis (ABA) have been empirically researched and clinically implemented for autistics/individuals diagnosed with autism spectrum disorder (ASD). Despite the plethora of evidence for the effectiveness of ABA-based interventions, some autism rights and neurodiversity activists have expressed concerns with ABA-based interventions. Concerns have included discontent with historical events and possible harm from the procedures and goals targeted. The purpose of this manuscript is to examine some expressed concerns about ABA-based intervention and suggest productive ways of moving forward to provide the best outcomes for autistics/individuals diagnosed with ASD. The authors represent stakeholders from multiple sectors including board certified behavior analysts, licensed psychologists, parents, and autistics/individuals diagnosed with ASD.

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 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.

Telehealth research in the field of applied behavior analysis (ABA) has focused on the training and supervision of others to implement various behavior analytic procedures. Current guidelines for practicing telehealth suggest that direct telehealth services may be appropriate for some individuals diagnosed with autism spectrum disorder, but more research is needed. This study evaluated the effects of discrete trial teaching with instructive feedback in a dyad arrangement delivered directly via telehealth to teach tact relations to 6 children diagnosed with autism spectrum disorder. All participants and the experimenter were located in different physical locations. All participants learned their primary and secondary targets, and 5 of the participants acquired the observational primary and secondary targets without direct teaching. Areas of future research and clinical implications are discussed in the context of telehealth service delivery.

The teaching interaction procedure is an evidence-based procedure that has been utilized for the development of social skills. The teaching interaction procedure consists of labeling the targeted skill, providing a meaningful rationale for the importance of the skill, describing the steps of the targeted skill, modeling the skill, and providing feedback throughout the interaction. Although the teaching interaction procedure has been used to teach a variety of social skills to children and adolescents diagnosed with autism spectrum disorder (ASD) and other social and behavioral disorders, its use has not been evaluated for training staff. The purpose of this study was to evaluate the use of a teaching interaction procedure to teach 3 interventionists the skills to implement a teaching interaction procedure to target the development of social skills for children diagnosed with ASD. The results of a multiple-baseline design showed the teaching interaction procedure was effective at teaching all 3 interventionists how to implement a teaching interaction procedure.
RESUMEN
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.
RESUMEN
Level systems have been described as a framework which can be used to shape behavior through the systematic application of behavioral principles. Within level systems, an individual moves up and down through various levels contingent upon specific behaviors. Although level systems are commonly used within schools and other settings, they have a limited empirical literature base, and there is debate over the efficacy and overall acceptance of level systems. More especially, there is scant empirical literature on the use level systems to improve socially significant behaviors (e.g., synchronous engagement) with individuals diagnosed with autism spectrum disorder (ASD). The purpose of this study was to evaluate the effectiveness of a level system with a structured, yet flexible approach to movement on improving synchronous engagement with two dyads of children diagnosed with ASD. The results of an ABAB reversal design indicated that the level system was effective at improving synchronous engagement for both dyads. The results are discussed in relation to potential future research difficulties and clinical implications.
RESUMEN
The teaching of receptive labels (i.e., auditory-visual conditional discriminations) is common among early intervention programs for individuals diagnosed with autism spectrum disorder (ASD). Discrete trial teaching (DTT) is a common approach used to teach these receptive labels. Some have argued that the stimuli within the array, target and non-target, must be counterbalanced to prevent the development of undesired stimulus control. The purpose of the present study was to evaluate the effectiveness of three different approaches to stimulus rotation to teach receptive labels to five young children diagnosed with ASD. These approaches included counterbalanced, fixed, and clinician's choice. The results of an adapted alternating treatment design replicated across three stimulus sets and five participants indicated that all three methods of rotation were effective. Maintenance and generalization for targets taught in all three conditions was also assessed. The implications of the results with respect to current teaching practices in early intervention programs are discussed.
RESUMEN
J. B. Leaf et al. (Behavior Analysis in Practice, 9, 152-157, 2016) wrote a commentary on social thinking (ST), an intervention commonly implemented for individuals diagnosed with autism spectrum disorder (ASD). The authors described what constitutes scientific, pseudoscientific, and antiscientific evidence and contended that ST aligns with the definition of pseudoscience and, to date, is not empirically supported or evidence based. Crooke and Winner (Behavior Analysis in Practice, 9, 403-408, 2016) responded, arguing that ST meets their definition of an evidence-based practice and identifying purported misconceptions and inaccuracies described by J. B. Leaf et al. In the current article, the authors clarify the original arguments, critically evaluate Crooke and Winner's definition of what constitutes evidence-based practice, further evaluate the research on ST, discuss issues regarding how ST is conceptualized, and express concerns about the endorsement and use of an eclectic approach to treating ASD. As this response was written by behavior analysts, it specifically addresses the conceptual consistency of this approach from a behavior-analytic worldview.
RESUMEN
Researchers have demonstrated that comprehensive behavioral intervention can result in significant improvements in the lives of individuals diagnosed with autism spectrum disorder (ASD; e.g.; Lovaas, Journal of Consulting and Clinical Psychology 55(1):3-9, 1987; McEachin et al., American Journal of Mental Retardation 97(4):359-372, 1993). This intervention has occurred in a variety of settings (e.g., school, home, and clinic). Even though procedures based upon the principles of applied behavior analysis (ABA) can be implemented across a variety of settings, there is often confusion about the differences and relative advantages of home- versus clinic-based settings. The purpose of this paper is to provide a discussion of home- and clinic-based intervention within the context of a progressive approach to ABA and discus possible advantages of each type of setting.

In 2014, the Behavior Analyst Certification Board (BACB®) initiated a program for credentialing behavior technicians. The new credential, Registered Behavior Technician™ (RBT®), is for providers of behavioral intervention to a wide range of individuals with mental health needs and developmental delays, including individuals diagnosed with autism spectrum disorder (ASD). The RBT® would represent the entry-level position within the range of the BACB® credentials. Despite the increasing acceptance of this newest level of credential from the behavioral community, the authors of this paper have substantial concerns with the RBT® credential as it relates to the delivery of intervention to individuals diagnosed with ASD. The purpose of this paper is to detail these concerns and propose remedies that would ensure that individuals diagnosed with ASD receive effective behavioral intervention.
RESUMEN
The present study evaluated the effects of instructive feedback embedded within a group discrete trial teaching to teach tact relations to nine children diagnosed with autism spectrum disorder using a nonconcurrent multiple-baseline design. Dependent variables included correct responses for: primary targets (directly taught), secondary targets (taught via instructive feedback), primary observational targets (directly taught to other members of the group), and secondary observational targets (taught via instructive feedback provided to other members of the group). Results showed that all nine participants reached the mastery criterion for the primary targets, as well as acquired the secondary and observational targets without direct teaching. Clinical implications and areas for future research are provided.

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.

In this study, we evaluated the effects of positional prompts on teaching receptive identification to six children diagnosed with autism spectrum disorder (ASD). The researchers implemented a most-to-least prompting system using a three level hierarchy to teach receptive picture identification. Within the prompting hierarchy, only positional prompts were used. The most assistive prompt was placing the target stimulus 12 in. closer to the participant, the less assistive prompt was placing the target stimulus 6 in. closer to the participant, and no prompt was placing the target stimulus in line with the alternative stimuli. A non-concurrent multiple baseline design across behaviors was used to evaluate the effectiveness of the positional prompt. Results indicated that the implementation of positional prompts resulted in participants reaching mastery criterion and maintaining skills at follow-up for the majority of the participants. The results of the study have both future clinical and research implications.
RESUMEN
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.
RESUMEN
Today, there are several interventions that can be implemented with individuals diagnosed with autism spectrum disorder. Most of these interventions have limited to no empirical evidence demonstrating their effectiveness, yet they are widely implemented in home, school, university, and community settings. In 1996, Green wrote a chapter in which she outlined three levels of science: evidence science, pseudoscience, and antiscience; professionals were encouraged to implement and recommend only those procedures that would be considered evidence science. Today, an intervention that is commonly implemented with individuals diagnosed with autism spectrum disorder is Social Thinking®. This intervention has been utilized by behaviorists and non-behaviorists. This commentary will outline Social Thinking® and provide evidence that the procedure, at the current time, qualifies as a pseudoscience and, therefore, should not be implemented with individuals diagnosed with autism spectrum disorder, especially given the availability of alternatives which clearly meet the standard of evidence science.
RESUMEN
Applied behavior analysis (ABA) is a science and, therefore, involves progressive approaches and outcomes. In this commentary we argue that the spirit and the method of science should be maintained in order to avoid reductionist procedures, stifled innovation, and rote, unresponsive protocols that become increasingly removed from meaningful progress for individuals diagnosed with autism spectrum disorder (ASD). We describe this approach as progressive. In a progressive approach to ABA, the therapist employs a structured yet flexible process, which is contingent upon and responsive to child progress. We will describe progressive ABA, contrast it to reductionist ABA, and provide rationales for both the substance and intent of ABA as a progressive scientific method for improving conditions of social relevance for individuals with ASD.
