Use of a Level System with Flexible Shaping to Improve Synchronous Engagement.

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.

Evaluating Three Methods of Stimulus Rotation when Teaching Receptive Labels.

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.

Social Thinking®, Pseudoscientific, Not Empirically Supported, and Non-Evidence Based: a Reply to Crooke and Winner.

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.

Concerns About the Registered Behavior Technician™ in Relation to Effective Autism Intervention.

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.

Instructive feedback embedded within group instruction for children diagnosed with autism spectrum disorder.

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.

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.

An Evaluation of Positional Prompts for Teaching Receptive Identification to Individuals Diagnosed with Autism Spectrum Disorder.

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.

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.

Social Thinking®: Science, Pseudoscience, or Antiscience?

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.

Applied Behavior Analysis is a Science and, Therefore, Progressive.

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.

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.

Comparing the teaching interaction procedure to social stories: a replication study.

This study compared the teaching interaction procedure to social stories implemented in a group setting to teach social skills to three children diagnosed with autism spectrum disorder. The researchers taught each participant one social skill with the teaching interaction procedure, one social skill with the social story procedure, and one social skill was assigned to a no intervention condition. The teaching interaction procedure consisted of didactic questions, teacher demonstration, and role-play; the social story procedure consisted of reading a book and answering comprehension questions. The researchers measured participants' performances during probes, responses to comprehension questions, and responding during role-plays. The results indicated that the teaching interaction procedure was more efficacious than the social story procedure across all three participants.

Observational effects on the preferences of children with autism.

Children with an autism spectrum disorder (ASD) may play with limited objects or toys, making it difficult for teachers to identify reinforcers to use in teaching new skills. The goal of this study was to alter children's preferences from highly preferred toys to toys that were originally less preferred using an observational pairing procedure. Child participants observed a preferred adult playing with toys that were initially less preferred by the child. This intervention resulted in a shift in preference toward the item manipulated by the adult. Maintenance of the changed preference was idiosyncratic across participants. Results suggest a procedure for expanding the range of items that students with ASD will select.

Comparing the teaching interaction procedure to social stories for people with autism.

This study compared social stories and the teaching interaction procedure to teach social skills to 6 children and adolescents with an autism spectrum disorder. Researchers taught 18 social skills with social stories and 18 social skills with the teaching interaction procedure within a parallel treatment design. The teaching interaction procedure resulted in mastery of all 18 skills across the 6 participants. Social stories, in the same amount of teaching sessions, resulted in mastery of 4 of the 18 social skills across the 6 participants. Participants also displayed more generalization of social skills taught with the teaching interaction procedure to known adults and peers.
