We modified functional analysis procedures to include a condition in which we reinforced problem behavior by complying with a child's mands. After identifying compliance with mands as a reinforcer, we evaluated the efficacy of a token system with a response‐cost contingency and incorporated discriminative stimuli to signal when mands would be reinforced. The token system with response cost effectively reduced problem behavior. Similar procedures may be beneficial when continuous adult compliance is not possible, when adults want to control when they will comply with the child's mands, or to build a child's tolerance for adult‐directed situations.  相似文献

Schedule thinning is an essential step in treating problem behavior, yet little research has been conducted to determine the method associated with sustained treatment effects. A frequently used method for thinning reinforcement is contingency‐based progressive delay, which requires the individual to meet some criteria before the reinforcers are returned. The response requirement could be dependent on (a) contextually appropriate behavior (differential reinforcement of alternative behavior‐based thinning) or (b) absence of problem behavior (differential reinforcement of other behavior‐based thinning). A translational arrangement with college students was implemented to determine the effects of these 2 response requirements. Tolerance was observed regardless of thinning method and was indicated by low rates of responding to the analogue problem behavior; however, more contextually appropriate behavior occurred during differential reinforcement of alternative behavior‐based thinning. These results support the use of response requirements for behaviors that are expected of the individual when reinforcement is not immediately forthcoming.  相似文献

Jessel, Hanley, and Ghaemmaghami (2016) reported the results of 30 interview‐informed, synthesized contingency analyses (IISCAs) and found the IISCAs to be an effective tool for identifying the functions of problem behavior across a variety of topographies, participants, and settings. Jessel et al. did not, however, include data on the effectiveness of the corresponding treatments. In the current study, we collected and summarized 25 additional applications, from analysis to treatment, in which the IISCA was applied in an outpatient clinic. The IISCA identified various social functions of problem behavior, which informed personalized treatments of functional communication training with contingency‐based reinforcement thinning. A 90% or greater reduction in problem behavior was obtained for every participant by the end of the treatment evaluation. The assessment and treatment process was socially validated by caregivers who rated the procedures highly acceptable and helpful, and the improvement in their child's behavior highly satisfactory.  相似文献

Effective nonpunitive procedures for reducing counterproductive classroom behaviors are of potential benefit to both students and teachers. A recent strategy for dealing with this class of problem behaviors involves the reinforcement of acceptably low levels of such behavior. The laboratory version of this procedure, called differential reinforcement of low rates of responding (or DRL), provides for a reinforcer to be delivered contingent upon a response that is separated from the last preceding response by a minimum amount of time. To make this procedure more amenable to classroom use, the present authors have modified it so that a reinforcer is delivered if fewer than a specified number of responses occur within a preset time interval (Deitz and Repp, Journal of Applied Behavior Analysis, 1973, 6 , 457–463). Previous studies using this procedure have found it effective in reducing and maintaining low rates of targeted behaviors. However, these effects have been demonstrated with groups of subjects and/or individuals from dependent populations. The present study investigated use of this modified DRL procedure with individual students in normal elementary classrooms. In the first of three studies, “talk-outs” of an 11-yr-old fifth-grade male were reduced when nonexchangeable gold stars were made contingent on two or fewer responses per session. During baseline sessions, an average of 4.45 talkouts were observed per 45-min session. Average responding subsequently fell to 1.83 when the modified DRL contingency was applied, increased to 7.60 during a reversal phase, and dropped again to an average of 1.20 when the contingency was reapplied. In the second study, out-of-seat behavior of a 12-yr-old sixth-grade female was reduced when gold stars were made contingent on two or fewer responses per 45-min class period. Baseline responding averaged 6.10 responses per session. When the contingency was applied, average responding fell to 0.16. During the reversal period, responding increased to an average of 6.00 and fell again, after the contingency was re-introduced to an average of 0.40. In the third study, a reduction in both talking-out and out-of-seat behaviors of another 11-yr-old fifth-grade male was demonstrated with a multiple-baseline design. Using different lengths of baselines, gold stars were made contingent first on a low rate of out-of-seat behavior, and then on a low rate of talk-outs. Out-of-seat responding fell from a baseline average of 7.50 to a treatment average of 1.14. Talk-outs went from a baseline average of 4.66 to a treatment average of 1.14. In all three studies, the modified DRL procedure proved effective with the children and was manageable by the classroom teacher. For the students, nonexchangeable conditioned reinforcers (stars) were sufficient to maintain lowered rates of inappropriate behavior with the modified DRL schedule; there was no need for an elaborate token economy, a process that in many cases may be only a form of behavioral “overkill”. As in other studies investigating DRL schedules, students were not informed of their accumulation of responses; the differential effects of providing or withholding this feedback need to be investigated. Overall, these studies add single-subject replication with normal children to the literature on modified DRL procedures.  相似文献

Rats were used in a conditioned-suppression paradigm to assess the effects of contingency variations on responding to a conditioned inhibitor (CS-) and a conditioned excitor (CS+). In Experiment 1, various unconditioned stimulus (US) frequencies were equated across the presence and absence of a CS- in the context of either background cues (continuous-trial procedure) or an explicit neutral event (discrete-trial procedure). With both procedures, a CS-alone treatment enhanced inhibition, whereas treatments involving 50% or 100% reinforcement for the CS- eliminated inhibition without conditioning excitation to that CS. The latter outcome also occurred in Experiment 2, with discrete-trial training equating considerably reduced US frequencies for the presence and absence of the CS-. In further evidence that inhibition was eliminated without conditioning excitation to the CS-, Experiment 3 showed that a novel CS did not acquire excitation when 25%, 50%, or 100% reinforcement was equated across the presence and absence of that CS in the context of a discrete-trial event. Using the procedures of Experiment 1, Experiment 4 showed that a CS+ was extinguished by a CS-alone treatment but was substantially maintained by treatments involving 50% or 100% uncorrelated reinforcement. These effects for a CS+ and a CS- implicate CS-US contiguity, rather than contingency, as the factor determining the extinction of a CS.  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

Although applied behavior analysis has generated many highly effective behavior‐change procedures, the procedures have not always been effectively disseminated. One solution to this problem is the use of video technology, which has been facilitated by the ready availability of video production equipment and software and multiple distribution methods (e.g., DVD, online streaming). We review a recent DVD that was produced to disseminate the successful experimental functional analysis procedure. The review is followed by general recommendations for disseminating behavior‐analytic procedures via video technology.  相似文献

Group-oriented contingencies are arranged to target the behavior of a group of people simultaneously. Overall, group-oriented contingencies have been shown to be effective in both decreasing problem behavior and increasing appropriate behavior. However, results are mixed regarding which type(s) of group-oriented contingency is most effective for changing behavior. In addition, although there are anecdotal reports of positive and negative side effects when using group-oriented contingencies, little research has involved direct measurement of these potential side effects. The purposes of the current study were to (a) compare the effects of three types of group-oriented contingencies for increasing on-task behavior and decreasing problem behavior, (b) determine whether implementing a group-oriented contingency for one behavior resulted in changes in a non-targeted behavior, and (c) determine how often and under what conditions side effects occurred within group-oriented contingencies conditions for two groups of preschool children. The results of the study were mixed. The results suggested that group-oriented contingencies were effective in decreasing problem behavior and increasing on-task behavior, but varied across groups as to which contingencies were the most effective at changing both behaviors. Secondary data suggested that side effects were associated with group-oriented contingencies, as well as the occurrence of problem behavior and reinforcer delivery.  相似文献

We conducted a four‐part investigation to develop methods for assessing and treating problem behavior evoked by noise. In Phase 1, 7 participants with developmental disabilities who were described as being hypersensitive to specific noises were exposed to a series of noises under controlled conditions. Results for 2 of the participants verified that noise was apparently an aversive event. In Phase 2, results of functional analyses indicated that these 2 participants' problem behaviors were maintained by escape from noise. In Phase 3, preference assessments were conducted to identify reinforcers that might be used during treatment. Finally, in Phase 4, the 2 participants' problem behaviors were successfully treated with extinction, stimulus fading, and a differential‐reinforcement‐of‐other‐behavior (DRO) contingency (only 1 participant required DRO). Treatment effects for both participants generalized to their home environments and were maintained during a follow‐up assessment. Procedures and results were discussed in terms of their relevance to the systematic assessment of noise as an establishing operation (EO) and, more generally, to the identification of idiosyncratic EO influences on behavior.  相似文献

Functional communication training (FCT) is commonly used to eliminate problem behavior. Not surprisingly, the efficacy of the intervention depends on fidelity to programmed procedures. For instance, problem behavior is likely to resurge if caregivers fail to reinforce mands during the maintenance stages of FCT. Despite this, recent translational work on arbitrary human responses suggests that incorporating multiple‐mand instruction into a serial‐training format may increase the probability of a recency effect, and a reversion of response resurgence (both desirable outcomes when mands are the most recently reinforced responses prior to extinction). Although promising, this effect has not been replicated with socially significant human behavior. Thus, we compared the relative effect of traditional FCT with that of serial FCT on the resurgence of the problem behavior, and mands, of 2 children. In contrast to previous research, we observed primacy effects for both subjects (i.e., the magnitude of the resurgence of problem behavior was greater than it was for any subsequently trained mand), and mand resurgence never occurred for one subject. Notwithstanding these limitations, the percentage of total responding allocated toward the resurgence of problem behavior was less in the serial FCT component relative to the traditional FCT component, and we observed a reversion of response resurgence for one subject.  相似文献

A mediated punishment procedure that involved recreating a behavioral sequence by guiding the subject through the behavior in the situation in which it occurred was used to suppress several severe problem behaviors in two developmentally delayed children. The mediational procedure was first used with a 4-year-old autistic boy for biting and then for foot stomping. Next the procedure was used for stealing and hoarding behavior with a multiply handicapped 17-year-old girl. Results indicated that the procedure was effective and produced relatively rapid results. One advantage of the procedure is that it provides an opportunity for trained personnel to apply restrictive procedures to low frequency behavior that occurs in their absence rather than relying on less qualified staff to implement the procedure immediately after the behavior occurs.  相似文献

Covariation within behavior repertoires of problem children were examined. Two boys, referred for psychological help, were observed both at school and at home for about 3 yr. A coded observation system permitted scoring of 19 child-behavior categories and six social-environment categories. After a two-month baseline, behavior categories were intercorrelated, demonstrating that each child showed a group of behaviors that covaried. These groupings were specific to the home and school settings. Contingency management procedures were then applied to each child's problem behaviors in one setting. Next, a reversal phase was instituted, followed by resumption of the initial contingency management phase. These three phases lasted seven months, until the end of the children's public school terms. Results showed that the baseline group of covarying behaviors continued to covary over the three experimental phases. The children then entered a remedial education setting for three summer months, and then returned to schools and were observed in follow-up for 2 yr. The baseline group of behaviors continued to covary during both phases. The behavior covariations could not be accounted for on the basis of temporal relationships between the behaviors and social environment categories. Although no behavior covariations extended across either child's home and school settings, contingency management procedures produced across-setting effects.  相似文献

Although much is known about techniques for teaching elementary pupils in the classroom, no procedures have been consistently effective in training teachers to use these techniques. In the present study, six teacher trainees were observed individually and trained sequentially to use a variety of teaching skills: praise for academic responses, praise for appropriate classroom behavior, correction procedures for incorrect academic responses, and token fines. These skills were examined under four conditions: (1) baseline sessions were taught by the trainees before any instructions on the use of the teaching skills. (2) Instruction sessions were taught by the trainees after they were given instructions describing the use of several teaching skills. (3) During each Imposed-Package session, the trainees received modelling, verbal feedback, graphic feedback, and grade and quiz contingencies on their use of a particular teaching skill. (4) During each Self-Selected Package session, a grade contingency was in effect with the trainees choosing the components (modelling, verbal feedback, graphic feedback, quiz contingency) they wanted included in their training package for a particular skill. The effects of instructions were quite varied. Large increases on three of the four skills occurred with one trainee; almost no changes occurred with another trainee; and changes with the remaining four trainees fell within these extremes. The Imposed and Self-Selected Packages reliably increased the use of teaching skills, including those skills for which instructions had not been effective. The Self-Selected Package was considered to be as effective as the Imposed Package, since the time required for training a teaching skill varied from two to nine sessions with both packages. Under the Self-Selected Package, the trainees chose from modelling, verbal feedback, and graphic feedback, but none chose the quiz contingency. Questionnaire data collected after training showed that all six trainees preferred the Self-Selected Package to the Imposed Package. The effectiveness of the Self-Selected Package, together with the trainees' preference for it, suggests that it may be desirable for teacher training programs to specify the teaching skills, arrange a contingency for performance, and allow trainees to choose which additional components are to be used in each training session.  相似文献

The effects of reward and cost token procedures on the social and academic behavior of two groups of elementary special-education students were assessed using a reversal design. Behavioral observations of three target subjects in each group revealed that both procedures were about equally effective in reducing rule violations and off-task behavior. Records kept on the daily arithmetic performance of all subjects showed that output doubled in both groups during the token phases, although accuracy remained unchanged. When students were allowed to choose either contingency, no pattern of preference was established. Small differences were found in teacher behavior: the reward procedure led to an increase in approval comments but cost procedures produced no changes in teacher behavior.  相似文献

The speed with which a functional analysis (FA) provides a convincing demonstration of the variables that influence problem behavior may be termed efficiency. Multiple FA formats have been developed to improve analytic efficiency while the core components of the Iwata, Dorsey, Slifer, Bauman, and Richman (1982/1994) procedures are maintained. We attempted to illustrate an alternative efficient process for conducting FAs of problem behavior that relied on modifying those core components. In Study 1, we describe 30 applications of the interview‐informed synthesized contingency analysis (Hanley, Jin, Vanselow, & Hanratty, 2014), which required an average of 25 min of analysis. The first sessions of these analyses were reanalyzed in Study 2 to determine if contingencies that controlled problem behavior could be identified in only 3 to 5 min. This was the case in 80% of analyses.  相似文献

Reinforcers affect behavior. A fundamental assumption has been that reinforcers strengthen the behavior they follow, and that this strengthening may be context‐specific (stimulus control). Less frequently discussed, but just as evident, is the observation that reinforcers have discriminative properties that also guide behavior. We review findings from recent research that approaches choice using nontraditional procedures, with a particular focus on how choice is affected by reinforcers, by time since reinforcers, and by recent sequences of reinforcers. We also discuss how conclusions about these results are impacted by the choice of measurement level and display. Clearly, reinforcers as traditionally considered are conditionally phylogenetically important to animals. However, their effects on behavior may be solely discriminative, and contingent reinforcers may not strengthen behavior. Rather, phylogenetically important stimuli constitute a part of a correlated compound stimulus context consisting of stimuli arising from the organism, from behavior, and from physiologically detected environmental stimuli. Thus, the three‐term contingency may be seen, along with organismic state, as a correlation of stimuli. We suggest that organisms may be seen as natural stimulus‐correlation detectors so that behavioral change affects the overall correlation and directs the organism toward currently appetitive goals and away from potential aversive goals. As a general conclusion, both historical and recent choice research supports the idea that stimulus control, not reinforcer control, may be fundamental.  相似文献

Delivery of alternative reinforcers in the presence of stimuli previously associated with reinforcement for target behavior increases the susceptibility of target behavior to relapse. To explore contingencies that might mitigate this counter‐therapeutic effect, we trained pigeons on a procedure that entailed extinction of previously reinforced target‐key pecking, access to a distinct stimulus context contingently on refraining from target behavior (differential‐reinforcement‐of‐other‐behavior; DRO), and reinforcement of alternative‐key pecks (differential‐reinforcement of alternative behavior; DRA) in that context. This DRO‐DRA treatment was compared with standard DRA in successive conditions, counterbalanced across pigeons. Target behavior extinguished more rapidly in the Standard‐DRA condition. When alternative reinforcement was discontinued, however, there was less resurgence after DRO‐DRA than after Standard DRA. In a third condition, the DRO contingency was suspended so that the former DRA stimuli were not presented (DRO‐NAC), and resurgence was greater than in the Standard‐DRA and DRO‐DRA conditions. Reinstatement produced by response‐independent reinforcers was small and similar across conditions. Subsequent reacquisition of target‐key pecking under baseline reinforcement conditions was faster following DRO‐NAC than Standard‐DRA or DRO‐DRA. These findings suggest that DRO‐DRA might serve as a useful method in clinical settings for reducing problem behavior while minimizing the threat of posttreatment relapse.  相似文献

Time‐out is a common negative punishment procedure in home and school settings. Although prior studies have shown time‐out is effective, more research is needed on its effects when implementation is imperfect. We evaluated delays to time‐out with 4 preschool children who engaged in some combination of aggression, property destruction, and rule breaking. Target behavior decreased for all subjects exposed to delayed time‐out, with 3 of 4 subjects displaying low levels of target behavior even when time‐out was delayed by 90‐120 s. These data suggest delayed time‐out might be effective in situations in which a caregiver or teacher cannot implement time‐out immediately.  相似文献

In the typical functional analysis in which the antecedent and consequent events associated with problem behavior are manipulated, the control condition involves elimination of both the relevant establishing operation (EO) and its associated contingency through a schedule of noncontingent reinforcement (usually fixed-time [FT] 30 s). In some functional analyses, however, antecedent events are manipulated in the absence of differential consequences, and a common test condition in such analyses also involves the delivery of reinforcement on an FT 30-s schedule. Thus, the same schedule of reinforcement (FT 30 s) is not considered to be an EO in the former type of analysis but is considered to be an EO in the latter. We examined the relative influences of EOs and reinforcement contingencies on problem behavior by exposing 6 individuals who engaged in self-injurious behavior (SIB) to four combinations of functional analysis conditions: EO present/contingency present, EO absent/contingency present, EO present/contingency absent, and EO absent/contingency absent. Results indicated that the only condition in which high rates of SIB were observed consistently was one in which the EO and the reinforcement contingency were both present. Implications of these results for the design of functional analysis test and control conditions are discussed.  相似文献

When discriminated interresponse-time (IRT) procedures have been used to assess preference relations among temporally extended operants, deviations from matching have been obtained. Using a yoked-control procedure, the present study found that key pecking in a discriminated IRT procedure has two sources of strength--that arising from the response-reinforcer contingency that is explicitly arranged, and that arising from a stimulus-reinforcer contingency that is a by-product of the explicitly arranged contingency. The key pecking of all lead birds, and that of 3 of the 4 birds exposed to a yoked autoshaping procedure, was controlled by the keylight that signaled the lead birds' criterion IRTs. Because stimulus control of key pecking by the keylight, whether autoshaped or discriminative, fosters deviations from matching, the discriminated IRT procedure does not provide an appropriate basis for conclusions about preference relations among IRTs.  相似文献
