The behavior-analytic approach to the assessment and treatment of problem behavior begins with a functional behavior assessment and concludes with function-based treatment implementation. Extinction bursts and the resurgence of problem behavior represent common barriers to successfully implementing these treatments. Recent research documents a…

Basic and retrospective translational research has shown that the magnitude of resurgence is determined by the size of the decrease in alternative reinforcement, with larger decreases producing more resurgence. However, this finding has not been evaluated prospectively with a clinical population. In Experiment 1, five participants experienced a…

Sensory-based interventions are commonly utilized by pediatric occupational therapy practitioners when working with children with disabilities. The purpose of this study was to examine the effects of fixed-time breaks with access to sensory stimuli on behavior that interfered with participation in pediatric occupational therapy sessions. Two boys…

Previous research assessing consequences of interpregnancy intervals (IPIs) on child development is mixed. Utilizing a population-based US sample (n = 5339), we first estimate the associations between background characteristics (e.g. sociodemographic and maternal characteristics) and short ([less than or equal to]1 year) and long (>3 years)…

We replicated and extended the study by Koegel, Dunlap, and Dyer (1980) by examining the effects of 3 intertrial-interval (ITI) durations on skill acquisition in 2 children with autism spectrum disorders. Specifically, we compared the effect of short (2 s), progressive (2 s to 20 s), and long (20 s) ITIs on participants' mastery of tacts or…

We conducted a preliminary investigation of a randomized dependent group contingency to decrease disruptive behavior during hallway transitions. Two first-graders, identified by their classroom teacher, participated in this study. A multiple baseline across transitions was used to evaluate the effects of the randomized dependent group contingency…

Multiple schedules with signaled periods of reinforcement and extinction have been used to thin reinforcement schedules during functional communication training (FCT) to make the intervention more practical for parents and teachers. We evaluated whether these signals would also facilitate rapid transfer of treatment effects across settings and…

Deficits in the perception of time and processing of changes across time are commonly observed in individuals with autism. This pilot study evaluated the efficacy of the use of the software tool Tic-Tac, designed to make time visual, in three adults with autism and learning difficulties. This research focused on applying the tool in waiting…

This multiple-study experiment evaluated the utility of assessing and treating severe self-injurious behavior (SIB) based on the outcomes of a functional analysis of precursor behavior. In Study 1, a precursor to SIB was identified using descriptive assessment and conditional probability analyses. In Study 2, a functional analysis of precursor…

We conducted 2 studies to determine whether dense and thin NCR schedules exert different influences over behavior and whether these influences change as dense schedules are thinned. In Study 1, we observed that thin as well as dense NCR schedules effectively decreased problem behavior exhibited by 3 individuals. In Study 2, we compared the effects…

We evaluated the effects of fixed-interval (FI), fixed-time (FT), and conjoint (combined) FI FT reinforcement schedules on the responding of 3 adults who had been diagnosed with schizophrenia. Responding on vocational tasks decreased for 2 of 3 participants under FT alone relative to FI alone. Responding under FI FT resulted in response…

In a 3-tiered, prevention-oriented framework, Tier II (secondary, targeted) interventions are designed for students whose problem behaviors have not responded to Tier I but are not severe enough to warrant an individualized Tier III intervention. Tier II interventions are implemented similarly across students receiving the intervention and can be…

The current study examined the effects of motivating operations on problem behavior and academic engagement for 2 students with autism. Classroom sessions were preceded by periods in which the participants had access or no access to the items functionally related to their problem behavior. Results suggested that presession access may result in…

Evidence regarding the effectiveness of after-school programs (ASPs) for reducing problem behaviors is mixed. Unstructured ASPs may increase antisocial behavior by increasing "deviancy training" opportunities, when peers reinforce deviant attitudes and behaviors. This research analyses approximately 3000 five-minute intervals from 398 observations…

Point systems, used in conjunction with positive reinforcement for appropriate behavior, have been used widely and successfully for decades to improve the inappropriate classroom behavior of students with emotional and behavioral problems (Cancio & Johnson, 2007; Drege & Beare, 1991; Gable & Strain, 1981; Jones, Dohrn, & Dunn, 2004; Klimas &…
