Maternal vocal imitation of infant vocalizations is highly prevalent during face-to-face interactions of infants and their caregivers. Although maternal vocal imitation has been associated with later verbal development, its potentially reinforcing effect on infant vocalizations has not been explored experimentally. This study examined the…

Coprophagia, the ingestion of fecal matter, occurs among some individuals with developmental disabilities and is associated with a variety of health risks (e.g., diarrhea, intestinal parasites, blood-borne pathogens; Parry-Jones & Parry-Jones, 1992). Studies that have evaluated operant-based treatments of coprophagia have been limited by a lack of…

According to behavioral momentum theory, preference and relative resistance to change in concurrent chains schedules are correlated and reflect the relative conditioned value of discriminative stimuli. In the present study, we explore the generality of this relation by manipulating the temporal context within a concurrent-chains procedure through…

Parallel experiments with rats and pigeons examined reasons for previous findings that in choices with probabilistic delayed reinforcers, rats' choices were affected by the time between trials whereas pigeons' choices were not. In both experiments, the animals chose between a standard alternative and an adjusting alternative. A choice of the…

The effect of a fixed-time (FT) schedule involving the delivery of preferred stimuli prior to the issuance of a low-probability instruction was evaluated with 2 young children with autism. The FT schedule was introduced according to a reversal design with 3 target instructions, 1 for the first child and 2 for the second child. Compliance increased…

In 2008, the "Journal of Positive Behavior Interventions" ("JPBI") celebrated 10 years in publication. As the flagship journal of positive behavior support (PBS), it is important to periodically examine the research published in "JPBI" to determine whether it reflects the basic principles of PBS, to explore the ways in which PBS is being…

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 &…

Household pets can have a positive influence on quality of life for individuals who live with them (Bryant, 1990). Little previous research has investigated issues related to interaction between individuals with developmental disabilities and pets. In this study, we used simple behavioral intervention procedures to decrease pet mistreatment by a…

An A-B single-case design assessed at-risk students' responsiveness to mathematics interventions. Four culturally and linguistically diverse second-grade students were given a Tier 2 standard protocol mathematics intervention that included number sense instruction, modeling procedures, guided math drill and practice of addition and subtraction…

Schools implementing Positive Behavior Interventions and Supports (PBIS) are often confronted with concerns from a variety of educational stakeholders about school climate, teaching behavioral expectations, the role of reinforcement, and labeling students. Administrators should be prepared to respond to these concerns with theoretical and…

Personal religiosity has been identified as a protective factor against juvenile delinquency. However, the influence of familial religiosity on delinquent behavior is less known. This study addresses this gap by investigating how family participation in organizational religious activities is related to delinquent involvement in early adolescence.…

The current study explored the extent to which a common measure of perceived implementation of critical features of School-wide Positive Behavior Support (SWPBS) predicted fidelity of implementation 3 years later. Respondents included school personnel from 261 schools across the United States implementing SWPBS. School teams completed the…

Every community has individuals or groups who manage to find better solutions to problems than their peers, although everyone has access to the same resources and challenges. Those are the positive deviants.

We evaluated the separate and combined effects of the antecedent manipulations of effective instruction delivery and time-in, as well as the effects of the addition of the consequent manipulation of contingent praise in a compliance training package for four elementary students displaying low levels of compliance. Four teachers were trained to…

Students in alternative, residential, and correctional settings present challenges in the classroom and facility due to the complexity and intensity of their behaviors. In addition, the factors typically associated with these settings including crowding, inconsistency, and conflicting staff perspectives on education and discipline present…
