Research has identified a variety of effective approaches for responding to errors during discrete-trial training. In one commonly used method, the therapist delivers a prompt contingent on the occurrence of an incorrect response and then re-presents the trial so that the learner has an opportunity to perform the correct response independently.…

Research on stimulus-stimulus pairing to induce novel vocalizations in nonverbal children has typically employed response-independent pairing (RIP) procedures to condition speech sounds as reinforcers. The purpose of the present study was to evaluate the effects of a response-contingent pairing (RCP) procedure on the vocalizations of three…

Although massed-trial instruction, distributed-trial instruction, and task interspersal have been shown to be effective methods of teaching skills to children with autism spectrum disorders, they have not been directly compared. In the current study, we taught 6 children to tact shapes of countries using these methods to determine which would…

We evaluated a treatment for elopement maintained by access to stereotypic door play. First, we conducted a functional analysis of elopement that produced undifferentiated results. Next, we conducted an assessment in which we evaluated the relation between elopement and door play. Results suggested a functional relation between the 2 behaviors…

Multiple baseline analysis of responses of three autistic children (5-12 years old) revealed that unpredictable supervision (in which the therapist was present on a random, intermittent, and unpredictable basis) produced much higher levels of on-task responding during the therapist's absence. Analysis of work completed during the therapist's…

To test reports that the development of programs for producing durable extra-therapy responding lags behind the development of programs for producing initial behavior change, responding was recorded continuously in both the therapy and extra-therapy settings for three autistic males (7 to 11 years old). (Author)

The experiment assessed, within a multiple baseline design, the possibility of improving the learning of three autistic children (4 to 7 years old) by changing arbitrary response-reinforcer relationships so that the target behaviors became functional (i.e., a direct part of the response chain required for the child to procure the reinforcer).…

Four boys (five to seven years old) with autistic-like behavior were treated for self-stimulatory behavior with three different treatment procedures--time out, differential reinforcement of other behavior (DRO), and overcorrection. (Author)

The study evaluated the effects of a time-efficient reinforcer assessment package with three preschoolers with autism. Systematic assessment of children's reinforcers for correct responding virtually eliminated nontargeted maladaptive behaviors, and yielded expected improvements in accuracy. (Author/DB)

The study examined effects of varied punishers (overcorrection, time-out, or a verbal "no" compared with the single presentation of one punisher (a loud noise) on occurrence of inappropriate behaviors in three developmentally delayed children (ages 5-6). Both formats produced a decrease in target behaviors, with the varied-punisher format slightly…

Analysis of the effects of a short break contingent on completed work with a 10-year-old boy with autism and profound mental retardation found the 20-second break increased responding more than a positive reinforcer did, and the reinforcing effects of a 20-second break were affected by the availability of positive reinforcers during the break. (DB)

This study observed a classroom of 15 students (ages 3 to 11) with behavior disorders, using amount of teacher attention to generate hypotheses about problem behavior function which were then validated in individual functional assessments. For 14 of the students, accurate hypotheses were efficiently generated by noting how teachers distributed…

A multicomponent intervention to change problem behavior, which prevented community integration of three adolescents with autism, was evaluated. The intervention (implemented in a supermarket setting) included choice making, embedding, functional communication training, building tolerance for delay of reinforcement, and presenting discriminative…

Functional communication training, extinction, and response chaining decreased escape-maintained aberrant behavior and increased task participation of 3 youth, ages 10 through 15, with moderate mental retardation, 2 of whom also had autism. Task escape was contingent on verbally responding and completing task steps. Behavior chaining also…

Prompting, positive and negative reinforcement, and a gradually extended reinforcement schedule were used with three autistic clients (two six-year-olds and one adolescent) to teach them to maintain on-task behaviors without constant supervision. Results indicated that appropriate behavior could be successfully maintained with only infrequent and…
