USE OF LATENCY TO PROBLEM BEHAVIOR TO EVALUATE DEMANDS FOR INCLUSION IN FUNCTIONAL ANALYSES

Few direct‐assessment procedures are designed to identify potential negative reinforcers (e.g., including demands in the escape condition of functional analyses). Two participants were systematically exposed to a series of demands nominated by caregivers as potential negative reinforcers. Sessions ended following the first instance of problem behavior, and a hierarchy of demand aversiveness was created based on the latency to the first problem behavior. Subsequent functional analyses confirmed the predictive value of the hierarchy, with shorter latency demands consistently producing more differentiated functional analysis outcomes.     

THE EFFECTS OF FUNCTIONAL ANALYSIS TEST SESSIONS ON SUBSEQUENT RATES OF PROBLEM BEHAVIOR IN THE NATURAL ENVIRONMENT

The present study was conducted to determine whether elevated response rates that occurred in an experimental functional analysis were correlated with higher post‐session response rates in the natural environment. Functional analyses indicated that the problem behavior of four children with developmental disabilities was maintained by common sources of reinforcement. Observational assessment in the natural environment showed no differences in post‐session rates compared with pre‐session rates for three participants, and the data for the fourth participant were equivocal. Overall, no convincing evidence was found to suggest that functional analyses might worsen post‐session problem behavior in the natural environment. Copyright © 2012 John Wiley & Sons, Ltd.     

Differential reinforcement with and without blocking as treatment for elopement

Blocking is a frequent component of treatments for elopement. Unfortunately, blocking may not always be feasible because elopement often occurs when supervision is low or the behavior cannot be prevented. The present study evaluated the use of blocking in the treatment of elopement by using differential reinforcement of other behavior with and without blocking. In this case, results suggested that blocking may be an essential component for differential reinforcement-based treatments of elopement.     

An alternative method of thinning reinforcer delivery during differential reinforcement

Differential reinforcement of alternative behavior (DRA) may result in rates of reinforcement that are impractical for caregivers to implement; therefore, recent research has examined methods for thinning reinforcer delivery during DRA. In this study, reinforcer delivery was thinned during DRA by restricting access to the participant's alternative response materials.
