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.

Titre : Applied Behavior Analysis is a Science and, Therefore, Progressive Type de document : Texte imprimé et/ou numérique Auteurs : Justin B. LEAF, Auteur ; Ronald LEAF, Auteur ; John MCEACHIN, Auteur ; Mitchell TAUBMAN, Auteur ; Shahla ALA’I-ROSALES, Auteur ; Robert K. ROSS, Auteur ; Tristram SMITH, Auteur ; Mary Jane WEISS, Auteur Année de publication : 2016 Article en page(s) : p.720-731 Langues : Anglais (eng) Mots-clés : Analyse fonctionnelle Applied behavior analysis Behavioral intervention Discrete trial teaching Functional analysis Index. décimale : PER Périodiques Résumé : 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.

Titre : Comparing Paired-Stimulus Preference Assessments With In-the-Moment Reinforcer Analysis on Skill Acquisition: A Preliminary Investigation Type de document : Texte imprimé et/ou numérique Auteurs : Justin B.

LEAF, Auteur ; Aditt ALCALAY, Auteur ; Daniel RAVID, Auteur ; Stephanie DALE, Auteur ; Alyne KASSARDJIAN, Auteur ; Kathleen TSUJI, Auteur ; Mitchell TAUBMAN, Auteur ; John MCEACHIN, Auteur ; Misty L. OPPENHEIM-LEAF, Auteur Article en page(s) : p.14-24 Langues : Anglais (eng) Mots-clés : autism,paired-preference assessment,preference,reinforcement Index. décimale : PER Périodiques Résumé : Today, the use of formal preference assessments, including paired-stimulus preference assessments, is widely utilized to help determine which items to use as reinforcers during intervention. A second way to determine potential reinforcers is to analyze multiple dimensions of a stimulus in the moment, a procedure known as in-the-moment reinforcer analysis. Although paired-stimulus preference assessments are widely used, there is no experimental evidence that extensive advance preference assessments actually produce higher rates of learning than in-the-moment reinforcer analysis. The present study compared rates of learning on a simple expressive labeling task when correct responses were reinforced with items selected based on extensive formal paired-preference assessments versus items selected by a teacher using in-the-moment analysis of reinforcer effects. The results indicated no clear difference in skill acquisition, but there were clear differences in terms of efficiency and maintenance.

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.

CIHON, Auteur ; Ronald LEAF, Auteur ; John MCEACHIN, Auteur ; Nicholas LIU, Auteur ; Noah RUSSELL, Auteur ; Lorri UNUMB, Auteur ; Sydney SHAPIRO, Auteur ; Dara KHOSROWSHAHI, Auteur Article en page(s) : p.2838-2853 Langues : Anglais (eng) Mots-clés : Abuse Autism Behavioral intervention Early intensive behavioral intervention Self-stimulatory behavior Index. décimale : PER Périodiques Résumé : 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.
