We conducted functional analyses and identified reinforcers for problem behavior for three individuals with developmental disabilities. Based on results of the functional analysis, we evaluated the rate, probability, delay, and duration of reinforcement for problem and appropriate behavior during descriptive parent-child observations. Results…

The effects of variable-interval (VI) and fixed-ratio (FR) schedules of reinforcement for work-related behavior and an organizer for the work materials (behavioral prosthesis) were evaluated with 3 adults with severe or profound mental retardation. The participants had been recommended for study because of high rates of off-task and aberrant…

Emotional and behavioral problems of students in the classroom have been rated as a major concern for teachers, administrators, and the public (Hardman & Smith, 2003; Macciomei, 1999). Without effective behavior management, a positive and productive classroom environment is impossible to achieve. The most effective model for producing behavior…

Functional analysis methodology is an assessment strategy that identifies sources of reinforcement that maintain problem behavior and prescribes individualized interventions that directly alter the conditions under which behavior occurs. In this article we describe the environmental determinants of problem behavior, methods for conducting…

The purpose of this study was to determine if specific classroom antecedents were associated with motor and vocal tics in two males diagnosed with Tourette's syndrome. A functional assessment consisting of teacher and student interviews, direct observations, brief functional analysis, and confirmatory naturalistic observations indicated that…

Since the re-authorization of the Individuals with Disabilities Education Act of 1997 functional assessment has become popular in designing interventions for people with challenging behaviour. The purpose of this study was to assess the applications of functional and structural analysis in the assessment of problem behaviour. The study analysed…

The purpose of this investigation was to evaluate a methodology for analyzing the interactive effects of two different antecedent variables on child noncompliance in an outpatient clinic. Phase 1 of this study consisted of antecedent manipulations to identify situations that occasioned problematic behaviors (i.e., presence or absence of the…

With their origins in scientific validation, behavior-analytic applications have understandably been developed with an engineering rather than a crafting orientation. Nevertheless, traditions of craftsmanship can be instructive for devising aesthetically pleasing arrangements--arrangements that people will try, and having tried, will choose to…

Social-emotional competence--it is a critical part of every child's school success, and just like any academic subject, children need instruction in it. Developed by a top expert, these proven curricula will help promote the social-emotional competence and resilience of children and adolescents. Divided into four age levels from kindergarten…

Thousands of schools throughout the country are now implementing School-Wide Positive Behavior Support (SWPBS) as a way to improve school culture, safety, and climate. Research is needed to assess the effects of implementing SWPBS on (a) teacher stress and (b) teacher efficacy. The present pilot study provides a preliminary study of these…

School-wide positive behavior support (SWPBS) has been implemented in more than 4,000 schools as a means of addressing problem behavior in a systemic fashion. Preliminary outcomes (e.g., office discipline referrals, suspensions) indicate the effectiveness of SWPBS in decreasing school-wide behavior problems and creating a positive school climate.…

Previous research implies that stereotypic behavior tends to be maintained by the sensory consequences produced by engaging in the response. Few investigations, however, have focused on vocal stereotypy. The current study examined the noncommunicative vocalizations of 4 children with an autism spectrum disorder. First, functional analyses were…

We describe a training program to teach applied behavior analysis (ABA) knowledge competencies to paraprofessional staff (N = 47) at a habilitation services agency for adults with developmental disabilities. Before and following training, staff completed assessment of knowledge tests for three content areas: basic learning principles,…

Autism is a developmental disability that manifests as impairment in three primary areas: social interaction, communication and imaginative activities, and reactions to environmental stimuli. The appearance of autism spectrum disorder ranges from children who are very low functioning, nonverbal, stimulus seeking, aggressive, antisocial, and…

In offering a critical review of the problem we call "ADHD" (Attention Deficit Hyperactivity Disorder), this paper progresses in three stages. The first two parts feature the dominant voices emanating from the literature in medicine and psychology which, when juxtaposed, highlight an interdependency between these otherwise competing…
