Students with Attention Deficit Hyperactivity Disorders (ADHD) can present unique behavioral and academic challenges within the school environment. The Response to Intervention (RTI) and Positive Behavior Interventions and Supports (PBIS) movements have sought to formalize intervention systems to address the needs of all children. An integral…

The purpose of the present study was to apply the percentage of data points exceeding the median of baseline phase (PEM) approach for a meta-analysis of single-case experiments to compare the relative effectiveness of different kinds of reinforcers used in behavior modification. Altogether 153 studies were located, which produced 1091 effect…

Researchers and practitioners often employ timeout procedures to manage inappropriate classroom behavior. When implemented inappropriately, however, timeout can result in dangerous situations and have received increased scrutiny (i.e., seclusion). The timeout ribbon procedure can prevent some of the dangerous situations associated with other forms…

As individuals with autism age out of the educational system, families and practitioners are faced with a number of challenges, including placement concerns and limited behavioral support. Among the most significant concerns is the assessment and treatment of challenging behavior in this population. While assessment and treatment strategies have…

Reinforcers contingent on response variability exert powerful and precise control over levels of variability, from stereotypy to stochasticity. This paper reviews how variability-contingent reinforcers interact with non-contingent, eliciting events to influence the variability of operant responses. Relationships to stimulus control, choice,…

Applied behavior analysis and behavior therapy are now nearly a half century old. It is interesting to ask if and how these disciplines have changed over time, particularly regarding some of their key internal controversies (e.g., role of cognitions). We examined the first five years and the 2000-2004 five year period of the "Journal of Applied…

Methods and outcomes from functional behavioral assessment have been researched widely over the past twenty-five years. However, several important research questions have yet to be examined sufficiently. This quantitative review of developmental disability research aims to make comparisons of different functional behavioral assessment…

College students (N = 151) completed three in-class mathematics assignments that varied with respect to the order of short, medium, and long multiplication problems, including a short-to-long order, a long-to-short order, and a random order. Problem order within assignments did not significantly affect work accuracy, completion time, or assignment…

This paper will examine possible extinction properties of behavior-specific manual restraint. It will analyze the possibility of extinction being produced via restraint with respect to the target behavior's possible environmental functions. The theoretical analysis will involve the analysis of behavioral properties of restraint during two temporal…

This study evaluated the effects of using differential reinforcement of other behavior (DRO) with a differential reinforcement of alternative behavior (DRA) resetting time schedule to reduce stereotypy in a child with Rett Syndrome. The primary purpose of the investigation was to compare latency and choice as dependent measures to identify…

There are a number of instructional approaches available within ABA, each of which is uniquely suited to address specific deficits in learners with Autism Spectrum Disorders. Clinicians can utilize a combination of Discrete Trial Instruction (DTT), naturalistic strategies, and rate-building procedures to maximize the acquisition, generalization,…

The present study uses the PEM approach to synthesize the effectiveness of treatment on disruptive behaviors and simultaneously tests whether the higher validity of the PEM approach than that of the PND approach is repeatable. A hand search of the "Journal of Applied Behavior Analysis" was conducted, and reference lists from reviewed articles were…
