The purpose of the current investigation was to extend the literature on matched stimuli to three dissimilar forms of aberrant behavior (dangerous climbing and jumping, saliva manipulation, and hand mouthing). The results of functional analyses suggested that each behavior was automatically reinforced. Preference assessments were used to identify two classes of stimuli: items that matched the hypothesized sensory consequences of aberrant behavior (matched stimuli) and items that produced sensory consequences that were not similar to those produced by the aberrant behavior (unmatched stimuli). The effects of providing continuous and noncontingent access to either the most highly preferred matched or the most highly preferred unmatched stimuli were assessed relative to a condition in which no stimuli were available. Overall results suggested that providing access to items that matched the hypothesized sensory consequences of aberrant behavior may be more effective than simply selecting stimuli either arbitrarily or based on the results of preference assessments alone. 相似文献

Transitions with nonhuman animals are typically framed as inescapable changes in signaled reinforcement schedules that result in a pause in responding unique to switches from rich to lean schedules. Pausing is considered to be a function of the aversive qualities of the contrasting reinforcement schedules. Transitions are typically framed in applied research as physical changes in location that evoke problem behavior maintained by the escape of an aversive event or resumption of a preferred event. We attempted to extend the basic framing of transitions to behaviors and contexts of social significance and evaluate a novel treatment for the problem of dawdling by 3 boys who had been diagnosed with autism spectrum disorder during rich‐to‐lean transitions. Dawdling during physical transitions was most readily observed when transitioning to lean contexts in Experiment 1. We then shortened transition duration in Experiment 2 by programming unsignaled and probabilistic rich reinforcement in the upcoming context. 相似文献

The effectiveness of functional communication training as treatment for problem behavior depends on the extent to which treatment can be extended to typical environments that include unavoidable and unpredictable reinforcement delays. Time‐based progressive delay (TBPD) often results in the loss of acquired communication responses and the resurgence of problem behavior, whereas contingency‐based progressive delay (CBPD) appears to be effective for increasing tolerance for delayed reinforcement. No direct comparison of TBPD and CBPD has, however, been conducted. We used single‐subject designs to compare the relative efficacy of TBPD and CBPD. Four individuals who engaged in problem behavior (e.g., aggression, vocal and motor disruptions, self‐injury) participated. Results were consistent across all participants, and showed lower rates of problem behavior and collateral responses during CBPD than during TBPD. The generality of CBPD treatment effects, including optimal rates of communication and compliance with demands, was demonstrated across a small but heterogeneous group of participants, reinforcement contingencies, and contexts. 相似文献

A believable demonstration of control over problem behavior is a necessary component of the functional analysis process. Control during a functional analysis has traditionally been defined in a binary manner: Differentiated outcomes point to an identifiable function and undifferentiated outcomes do not. However, it might be beneficial to characterize control as strong, moderate, or weak in order to evaluate the strength of evidence for experimental control during an efficient functional analysis format that requires only a single session. We analyzed the levels of control using 26 single‐session interview‐informed synthesized contingency analyses (IISCAs). Although shorter session duration (i.e., first 3 or 5 min of each session) tended to reduce the level of control, the majority of single‐session IISCAs resulted in evidence indicating strong levels of control when data from the full 10‐min session were included in the analysis. 相似文献

We conducted this study to determine if the efficiency of the functional analysis could be improved without detrimental effects on control. In Experiment 1, we reanalyzed functional analyses conducted for the problem behavior of 18 children. We analyzed rates of problem behavior during the first 5 min and first 3 min of the original 10-min sessions and evaluated if changes in the level of control over problem behavior by the programmed contingency were evident from the analyses of shorter session duration. In Experiment 2, we conducted 8 consecutive functional analyses with 3-min sessions to further evaluate the utility of brief session durations. We found that control over problem behavior was demonstrated when conducting functional analyses with sessions as brief as 3 min. 相似文献

Functional analysis can often be a lengthy process requiring time and resources not readily available to practitioners working with children who exhibit severe problem behavior. The interview‐informed synthesized contingency analysis (IISCA) was recently developed as an alternative functional analysis format that improved analytic efficiency by requiring only 25 min to conduct. Furthermore, a within‐session analysis of the first test session of the entire IISCA could reduce the process to as little as a single 5‐min session. We extended this previous research by conducting what was termed the single‐session IISCA with three boys who exhibited severe problem behavior. A function‐based treatment package, including reinforcement thinning, informed by the results of the single‐session IISCA nearly eliminated problem behavior for all three participants. We suggest that the single‐session IISCA could be a viable alternative to other functional analysis formats when time is limited. 相似文献
