Activity schedules consist of a series of visual discriminative stimuli, arranged in booklets or binders, which function as prompts for appropriate behavior. Although activity schedules are useful, their typical presentation in binders can be cumbersome and stigmatizing, placing additional barriers for independence and inclusion. The purpose of the present studies was to evaluate the usefulness of a wearable activity schedule and determine whether prompts provided by it would be sufficient to support completion of a complex chain of behaviors by young children. In Experiment 1, the Octopus watch® provided prompts to children of typical development to complete a morning routine independently. In Experiment 2, the usefulness of the watch was evaluated in children with autism spectrum disorder engaged in play activities in a clinical setting. In both experiments, children reliably displayed a greater proportion of independent engagement in target behaviors when prompts were delivered by the watch compared to control conditions. 相似文献

Individuals with autism spectrum disorder (ASD) often have few employment opportunities and a lower job quality than individuals of typical development. Social deficits and lack of independence may contribute to underemployment and unemployment of individuals with ASD. The ability to solve problems might ameliorate some of these barriers. We taught four adolescents with ASD a problem-solving strategy (i.e., use of a textual activity schedule) to assist with independent completion of vocational tasks in the face of three types of problems (e.g., missing or broken items) and nonproblem situations. Following introduction of the problem-solving strategy, all four participants independently completed the tasks when a problem was presented and responding generalized to untaught vocational tasks. 相似文献

Token schedules of reinforcement are ubiquitous in clinical settings, yet little research has thoroughly evaluated the effects of token schedules on responding in clinical settings. Basic research has shown token schedules of reinforcement produce lower response rates and larger pre‐ratio pauses compared to tandem schedules. The purpose of the current study was to determine whether the same effects are produced with adolescents with autism or related disorders. We examined response patterns under otherwise identical FR token and FR tandem schedules. Tokens suppressed responding for one participant only under high schedule values and for a second participant under common clinical schedule values; no difference in responding occurred between token and tandem schedules for two participants. These results support the systematic evaluation of token schedules of reinforcement in clinical settings. Additional applied research is needed on token schedules to further our understanding of the underlying mechanisms that contribute to the overall effectiveness of token economies. 相似文献

Repetitive and invariant behavior is a diagnostic feature of autism. We implemented a lag reinforcement schedule to increase response diversity for 6 participants with autism aged 6 to 10 years, 4 of whom also received prompting plus additional training. These procedures appeared to increase the variety of building-block structures, demonstrating that an intervention that includes differential reinforcement can increase response diversity for children with an autism spectrum disorder. 相似文献

Elopement can have serious or fatal consequences associated with leaving the presence of an adult or getting lost (e.g., traffic injury and drowning). Given the dangers associated with elopement, caregivers are likely to chase after their child when elopement occurs. Like other forms of attention that follow problem behavior, chasing and retrieving the child may serve as a reinforcer and therefore maintain elopement. However, no study to date has evaluated whether elopement is sensitive to positive reinforcement in the form of chase. We evaluated the effects of chase on elopement with an 8‐year old boy diagnosed with autism. Elopement was maintained, at least in part, by chase. We then conducted a treatment evaluation in which we tested the effects of various antecedent‐ and consequence‐based treatment components within a multiple schedule. 相似文献

We used photographic activity schedules to increase the number of play activities completed by children with autism during unstructured time on the playground. All 3 participants engaged in more playground activities during and after training, and they continued to complete activities when novel photographs were introduced. 相似文献

Deficits in response to name (RTN) are an early indicator of autism spectrum disorder (ASD), and RTN is a treatment goal in many early intervention curricula for children with ASD. However, little research has empirically evaluated methods for increasing RTN in children with ASD. We evaluated a series of conditions designed to increase RTN for 4 children with ASD using a multielement experimental design. The schedules of tangible reinforcement were thinned after mastery and generalization was tested across people and contexts. Tangible reinforcers were necessary to increase RTN for all 4 participants, and the schedule of reinforcement was successfully thinned with all participants after intervention. Generalization was also observed across people and experimental contexts. 相似文献

Three experiments examined the effect of signaling reinforcement on rats' lever pressing on contingencies that reinforced variable responding to extend the exploration of signaled reinforcement to a schedule that has previously not been examined in this respect. In Experiment 1, rats responding on a lag-8 variability schedule with signaled reinforcement displayed greater levels of variability (U values) than rats on the same schedule lacking a reinforcement signal. In Experiment 2, rats responding on a differential reinforcement of least frequent responses schedule also displayed greater operant variability with a signal for reinforcement compared with rats without a reinforcement signal. In Experiment 3, a reinforcement signal decreased the variability of a response sequence when there was no variability requirement. These results offer empirical corroboration that operant variability responds to manipulations in the same manner as do other forms of operant response and that a reinforcement signal facilitates the emission of the required operant. 相似文献

Despite its advantages, discrete‐trial instruction (DTI) has been criticized for producing rote responding. Although there is little research supporting this claim, if true, this may be problematic given the propensity of children with autism to engage in restricted and repetitive behavior. One feature that is common in DTI that may contribute to rote responding is the prompting and reinforcement of one correct response per discriminative stimulus. To evaluate the potential negative effects of rote prompts on varied responding, we compared the effects of modeling rote versus varied target responses during the teaching of intraverbal categorization. We also evaluated the effects of these procedures on the efficiency of acquisition of any one correct response. For all four children, any increase in varied responding was fleeting, and for two participants, acquisition was slower in the variable‐modeling condition. 相似文献

Although individuals with autism spectrum disorder (ASD) tend to behave repetitively, certain reinforcement contingencies (e.g., lag schedules) can be used to increase behavioral variability. In a lag schedule, reinforcers only follow responses that differ from recent responses. The present study was designed to promote variable play behavior in preschoolers with ASD interacting with playsets and figurines and to assess preference for variability and repetition contingencies. Data have shown a preference for variability in pigeons and college students, but this effect has not been explored in clinical populations. In this experiment, preschoolers with ASD were taught to discriminate between variability and repetition contingencies. Only play behaviors that met a lag schedule were reinforced in the presence of one color, and only repetitive behaviors were reinforced in the presence of another. After differential performance was established, participants experienced a concurrent chains schedule. Participants chose between the colors taught in training and then completed a play session with the selected contingency. One participant selected variability and repetition equally. The other participants showed a slight preference for variability. These results indicate that some individuals with ASD may play repetitively, not because they prefer repetition, but because they require additional teaching to play variably. 相似文献

The effect of a fixed-time (FT) schedule involving the delivery of preferred stimuli prior to the issuance of a low-probability instruction was evaluated with 2 young children with autism. The FT schedule was introduced according to a reversal design with 3 target instructions, 1 for the first child and 2 for the second child. Compliance increased for 2 of the 3 cases. A high-probability instruction sequence and guided compliance were implemented for the second instruction targeted for 1 child, with compliance increasing with guided compliance. 相似文献

Differential reinforcement procedures may promote unprompted correct responding, resulting in a quicker transfer of stimulus control than nondifferential reinforcement. Recent studies that have compared reinforcement arrangements have found that the most effective arrangement may differ across participants. The current study conducted an assessment of differential reinforcement arrangements (i.e., quality, schedule, and magnitude) and nondifferential reinforcement to identify the most effective arrangement for each participant. The assessment phase showed that the quality arrangement was the most efficient for all participants during auditory‐visual matching. Next, a validation phase was conducted to evaluate whether the assessment would predict the most effective arrangement across multiple skills. The results from the assessment phase were validated for all participants for the same skill. However, the results were only validated for one participant during the other skills (i.e., tact and intraverbal). The results are discussed in light of previous research and future areas of research. 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

When the rate of reinforcement for pigeons' key pecking varied over time following a sine waveform, performances were more consistent and reliable if a constant-rate reinforcement schedule was concurrently available on a second key than if only the sinewave-varying reinforcement schedule was available. In the two-key version, response rates clearly followed varying reinforcement rates with the same frequency, with no phase lag, and without breaks. In both versions, pecking rate was a power function of reinforcement rate. Sinewave-schedule performance waveforms qualified for engineering methods of frequency analysis and met criteria for a standard measurement system. 相似文献

Socialization skill deficiencies among adults with autism spectrum disorder (ASD) can lead to depression, anxiety, aggression, and physical health problems. Clinical interventions must treat primary deficiencies and prevent secondary conditions. A treatment model emphasizing the integration of physical activity with social intervention strategies for adults with ASD is proposed. 相似文献

Interventions for multiply maintained problem behavior often involve developing separate treatment conditions to address each function. Although isolating treatment conditions lead to positive outcomes, developing individual treatments for each identified function may be time-consuming. Alternatively, synthesizing treatment procedures may allow for more efficient treatment effects. We extended previous research by evaluating functional communication training (FCT) and chained schedules of reinforcement to treat multiply maintained problem behavior in children diagnosed with autism spectrum disorder. First, we conducted a functional analysis that concluded problem behavior was multiply maintained. Next, we taught functional communication responses (FCRs) and implemented a chained schedule of reinforcement. During the initial link, FCRs for a break resulted in the presentation of a choice menu with the other putative reinforcers in the terminal link. The relevant reinforcer was delivered contingent on the emission of subsequent FCRs. Finally, we systematically schedule thinned to caregiver-informed terminal schedules for each participant. The results of our study demonstrated that FCT, in combination with a sequential compound schedule of reinforcement, effectively decreased multiply maintained problem behavior and increased appropriate alternative responses (FCRs and compliance) even at terminal schedules of reinforcement. 相似文献

Five adolescents with autism, 5 adult control participants, and 4 child controls received rewards for varying their sequences of responses while playing a computer game. In preceding and following phases, rewards were provided at approximately the same rate but were independent of variability. The most important finding was that, when reinforced, variability increased significantly in all groups. Reinforced variability could provide the necessary behavioral substrate for individuals with autism to learn new responses. 相似文献
