False‐positive outcomes of functional analyses exist when exposure to the consequences in a condition strengthens a relation that did not previously exist. Two functional analyses (aggression and spitting) were conducted with a child with an intellectual disability. High rates of problem behavior occurred immediately in the attention condition of the functional analysis across response topographies, suggesting a clear functional response class. However, rates of aggression and spitting increased in the demand condition, following the initial block of sessions, indicating the possible creation of a novel contingent relation for spitting.

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

Research has demonstrated the feasibility of using positive reinforcement to treat problem behavior maintained by negative reinforcement. This line of research was extended in the current study. A functional analysis (FA) was conducted that suggested problem behavior was maintained by positive and negative reinforcement. Following the FA, a demand analysis was conducted with three demand conditions: one that replicated the demand condition from the FA, one that included presession exposure to a preferred item, and another that included presession exposure to preferred items and access to those items during breaks from demands. Although problem behavior occurred in all three demand conditions, within session analyses showed that problem behavior ceased during breaks from demands only when they included access to preferred items. This finding suggests that the motivating operation responsible for evoking problem behavior did not decrease when only a break was provided. Subsequent functional communication training and treatment analysis showed that treatments based on positive reinforcement were effective at reducing problem behavior, but those based on a negative reinforcement hypothesis were not.

We observed changes in the rates of response topographies during the demand condition of functional analyses for participants who demonstrated problem behavior maintained by escape. Over the course of the functional analysis for each participant, the number of topographies decreased from the first to the last session. Additionally, after the first session of the demand condition the rate of responding for one topography increased or remained at high levels while the rates of all other topographies decreased. The implications of these results when conducting functional analysis are discussed.  相似文献

During a functional analysis, a boy with autism and oppositional defiant disorder displayed destructive behavior that was maintained by attention in the form of verbal reprimands (e.g., “Don't hit me”). In a second analysis, contingent verbal reprimands produced higher rates of the behavior than contingent statements that were unrelated to the target response (e.g., “It is sunny today”), suggesting that some forms of attention were more reinforcing than others. A treatment based on these analyses reduced the behavior to near-zero levels.  相似文献

Accurate data collection on low‐frequency problem behavior is imperative given the paucity of opportunities to observe, record, and assess responding. Infrequently occurring behavior also provides a challenge for staff training relative to data collection. The present study evaluated the use of task clarification and feedback to teach direct‐care staff members to take data on recorded, simulated problem behavior. Results indicated that the procedures were effective in increasing accuracy not only in the contrived scenarios but also for problem behavior in the natural environment. These data suggest that task clarification and feedback on simulated problem behavior may be an effective method to increase accurate data collection on problem behavior in the natural environment.

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

We compared rates of academic responses and problem behavior during mathematics with distributed and accumulated reinforcer arrangements for 3 students with Attention‐Deficit Hyperactivity Disorder who engaged in chronic, severe problem behavior. All 3 students engaged in more academic responding and less problem behavior when reinforcers accumulated throughout the session, relative to conditions in which reinforcers were distributed throughout the session or withheld completely. We then conducted concurrent‐chain analyses to evaluate student preference for the reinforcer arrangements. Two students preferred distributed reinforcers, even though this arrangement continued to produce problem behavior. One student preferred accumulated reinforcers. Our data replicate previous findings regarding the efficacy of accumulated‐reinforcer arrangements, but suggest that students do not always prefer the most efficacious reinforcer arrangement.  相似文献

When standard analogue functional analysis procedures produce inconclusive results in children with conversational speech, the child's mands may help to identify the function of destructive behavior. In the current investigation, functional analyses conducted with 2 children who exhibited self-injury, aggression, and property destruction were undifferentiated across conditions. Based on informal observations and school and parental report, an analysis was conducted using mands to help determine the function of the destructive behavior. Using a multielement design, the therapist's compliance with the child's mands occurred either on a fixed-ratio (FR) 1 schedule or contingent on destructive behavior. Destructive behavior occurred at high and consistent levels when reinforcement of mands was contingent on destructive behavior and at near-zero levels when reinforcement of mands occurred on the FR 1 schedule. Based on these results, a second analysis was conducted in which compliance to mands occurred only when the child appropriately requested it (i.e., functional communication training plus extinction) and, for 1 child, compliance with mands was terminated contingent upon destructive behavior (i.e., functional communication training plus response cost). For both children, the rates of destructive behavior decreased markedly. The results suggest that assessing the child's mands may be useful in decreasing destructive behavior when a functional analysis is inconclusive.  相似文献

We examined the extent to which variations in session duration affected the outcomes of functional analyses. Forty-six individuals, all diagnosed with mental retardation and referred for assessment and treatment of self-injurious or aggressive behavior, participated in functional analyses, consisting of repeated exposure to multiple test conditions during 15-min sessions. For each set of assessment data, new data sets based on session durations of 10 and 5 min were prepared by deleting data from the last 5 and 10 min, respectively, of each session. Each graph (N = 138) was then reviewed individually by graduate students who had previous experience conducting and interpreting functional analyses, but who were blind to both participant identity and session duration. Interpretations of behavioral function based on the 10- and 5-min data sets were then compared with those based on the 15-min data sets. All of the 10-min data sets yielded interpretations identical to those based on 15-min data sets. Interpretations based on the 5-min and 15-min data sets yielded three discrepancies, all of which were the result of increased response rates toward the latter parts of sessions. These results suggest that the efficiency of assessment might be improved with little or no loss in clarity by simply reducing the duration of assessment sessions.  相似文献

Three participants whose problem behavior was maintained by contingent attention were exposed to 45‐min presessions in which attention was withheld, provided on a fixed‐time (FT) 15‐s schedule, or provided on an FT 120‐s schedule. Following each presession, participants were then tested in a 15‐min session similar to the social attention condition of an analogue functional analysis. The results showed establishing operation conditions increased problem behavior during tests and that abolishing operation conditions decreased problem behavior during tests.  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

The results obtained from two consecutive functional analyses conducted with a 6‐year‐old child with autism are described. In the initial functional analysis, the highest rates of problem behavior occurred in the play condition. In that condition, the delivery of attention appeared to occasion problem behaviors. A second functional analysis was conducted wherein an escape from attention condition and a tangible condition were added. In the second functional analysis, higher rates of responding were observed in the escape from attention and tangible conditions. The results suggested that problem behavior was maintained by negative reinforcement in the form of escape from attention and positive reinforcement in the form of gaining access to preferred tangible items. Problem behavior was treated using functional communication training combined with noncontingent reinforcement.  相似文献

Using a latency measure during a functional analysis of problem behavior increases the brevity of the assessment period and decreases risks resulting from exposure to contexts intended to evoke problem behavior. In addition, latency‐based functional analyses may be especially suitable for discrete behaviors such as elopement, which require resetting the environment after each instance of the response. We evaluated a comprehensive assessment and treatment package for the elopement of two children diagnosed with autism. We observed short latencies to elopement during the test condition of the analysis and no elopement during the control condition. We then taught the participants multiple forms of functional communication responses of increasing complexity while elopement was blocked. This was followed by the thinning of reinforcement to a terminal goal, creating a treatment package that nearly eliminated elopement and was socially validated by caregivers.  相似文献

The results of functional analyses of problem behavior can sometimes be undifferentiated. This lack of differentiation might be due to methodological problems or the absence of variables relevant to problem behavior in the assessment. The current case example provides a clarification of undifferentiated functional analysis results through the inclusion of a particular reinforcer that was not a part of the initial functional analysis. In addition, treatment data showed a decrease in problem behavior when the putative reinforcer was provided response‐dependently or response‐independently.

We compared the effects of extinction (EXT) and fixed-time (FT) schedules as treatment for severe problem behavior displayed by 3 individuals with developmental disabilities. First, functional analyses identified the reinforcers maintaining aberrant behavior for all 3 individuals. Next, EXT and FT schedules were compared using a multielement design. During EXT, the reinforcer maintaining problem behavior was withheld. During FT, the reinforcers were presented response independently at preset intervals. Results showed that FT schedules were generally more effective than EXT schedules in reducing aberrant behavior. FT schedules may be used in situations when extinction-induced phenomena are problematic.  相似文献

Research on functional response classes has applied significance because less severe forms of problem behavior have been found to co‐occur with more severe forms. In addition, the most severe forms of problem behavior are sometimes targeted for intervention without monitoring other less severe forms. In such cases, it is unknown whether and how untreated forms of problem behavior covary with the targeted behaviors. The present study employed a translational procedure (with button presses as the target behavior) to investigate response covariation under noncontingent reinforcement with typically developing preschoolers. The results indicated that noncontingent reinforcement was generally effective in decreasing all response class members when only one member was targeted.  相似文献

Elopement is a common form of problem behavior but is relatively underrepresented in the functional analysis literature. One barrier to assessing elopement experimentally is the need to retrieve the subject following an instance of elopement. This retrieval confounds programmed session contingencies when the goal is to obtain repeated measurement of free‐operant behavior. The current study evaluated latency to elopement as an alternative to free‐operant measurement. We first compared response latency to allocation in 5‐min sessions and then measured latency alone in a trial‐based format. The identified reinforcers matched across both data analysis modalities in the session‐based assessments, and the trial‐based functional analysis showed a significant time savings in identifying the function of behavior over a session‐based assessment. Results indicated that elopement serves idiosyncratic social functions in young children with intellectual and developmental disabilities, and that a latency‐based assessment saves time while yielding equally clear results.  相似文献

We evaluated one method for determining whether response suppression under noncontingent reinforcement (NCR) is a function of satiation or extinction. Three individuals with developmental disabilities who engaged in self-injurious behavior (SIB) or aggression participated. Results of functional analyses indicated that their problem behavior was maintained by social-positive reinforcement. NCR procedures, individualized for each participant, were implemented in a multiple baseline across subjects design and were associated with decreases in all participants' problem behavior. Identification of the mechanism by which NCR produced these effects was based on examination of cumulative records showing response patterns during and immediately following each NCR session. Satiation during NCR should lead to a temporary increase in responding during the post-NCR (extinction) period due to a transition from the availability to the unavailability of reinforcement (satiation to deprivation). Alternatively, extinction during NCR should reveal no increase in responding during the extinction period because the contingency for the problem behavior would remain unchanged and the transition from satiation to deprivation conditions would be irrelevant. Results suggested that the operative mechanisms of NCR were idiosyncratic across the 3 participants and appeared to change during treatment for 1 of the participants.  相似文献
