Using real-time recording to enhance the analysis of within-session functional analysis data.

Functional analysis methods have become standard practice for determining the maintaining variables of problem behavior. The analysis of within-session response patterns has been proposed as a useful adjunct to the functional analysis. Many within-session analyses have been conducted on data obtained from interval scoring methods. However, interval methods only provide an estimate of within-session data. The authors briefly describe a real-time recording method and provide a rationale for its use. The authors then provide descriptions of several research studies from their lab in which real-time data were crucial in determining behavioral function from experimental analyses.

Using fixed-time schedules to maintain behavior: a preliminary investigation.

The purpose of this study was to evaluate the potential of fixed-time (FT) schedules to maintain behavior. Two children who had been diagnosed with autism were taught a functional task. Subsequently, three different FT schedules (i.e., yoked, thin, dense) were compared to determine their capacity to maintain task responding. Results suggested that FT schedules may be used to maintain previously acquired behavior.

A review of "noncontingent" reinforcement as treatment for the aberrant behavior of individuals with developmental disabilities.

The term noncontingent reinforcement (NCR) refers to the delivery of an aberrant behavior's known reinforcer on a response-independent basis. The typical result is a decrease in responding from baseline (i.e., reinforcement) levels. NCR has become one of the most reported function-based treatments for aberrant behavior in the recent literature. The purpose of this review is to briefly discuss the history of the procedure and summarize the findings from the treatment research literature. The review is organized into the following sections: (a) basic research on NCR, (b) NCR as a control procedure, (c) NCR as a function-based treatment, (d) considerations in the programming of NCR schedules, (e) behavior-change mechanisms underlying NCR effects, and (t) directions for future research.

A variation of noncontingent reinforcement in the treatment of aberrant behavior.

We examined the effectiveness of a variation of noncontingent reinforcement (NCR) that incorporated a stimulus-delay procedure in the reduction of aberrant behavior maintained by positive reinforcement. Functional analyses for three individuals diagnosed with developmental disabilities indicated that their behaviors were maintained by positive reinforcement: one in the form of access to a tangible item, another by attention, and the third by physical contact. We implemented NCR with the delay procedure with two participants using reversal designs to evaluate effects. We also compared this NCR variation and DRO with the third participant to evaluate reinforcer-delivery rates. The variation of NCR was successful in reducing all aberrant behavior to near-zero levels. A comparison of reinforcer delivery between NCR with the stimulus-delay procedure and DRO demonstrated that the participant accessed more reinforcement with NCR. Results are discussed in the context of enhancing decelerative interventions with emphases on minimizing response effort for caregivers and maximizing access to reinforcement for the individuals.
