The earliest stages of functional communication training (FCT) involve providing immediate and continuous reinforcement for a communicative response (FCR) that is functionally equivalent to the targeted problem behavior. However, maintaining immediate reinforcement is not practical, and the introduction of delays is associated with increased…

Previous studies have focused on whether a trial-based functional analysis (FA) yields the same outcomes as more traditional FAs, and whether interventions based on trial-based FAs can reduce socially maintained problem behavior. We included a full range of behavior functions and taught 3 teachers to conduct a trial-based FA with 3 boys with…

We evaluated interrater agreement across multiple respondents on anecdotal assessments and compared cases in which agreement was obtained with outcomes of functional analyses. Experiment 1 evaluated agreement among multiple respondents on the function of problem behavior for 27 individuals across 42 target behaviors using the Motivation Assessment…

Previous research has demonstrated the efficacy of the noncontingent delivery of foods and liquids at suppressing rumination, the repeated regurgitation and rechewing of partially digested food. However, it is unclear how long this reduction is maintained after caregivers terminate this procedure. The current study examined the direct and distal…

Blocking is a frequent component of treatments for elopement. Unfortunately, blocking may not always be feasible because elopement often occurs when supervision is low or the behavior cannot be prevented. The present study evaluated the use of blocking in the treatment of elopement by using differential reinforcement of other behavior with and…

Preferences of 2 children with developmental disabilities, whose functional analyses indicated that their problem behavior was maintained by access to tangible items, were assessed using three formats (i.e., paired stimulus [PS], multiple-stimulus without replacement [MSWO], and free operant [FO]). The experimenter administered each format five…

Fixed momentary schedules of differential reinforcement of other behavior (FM DRO) generally have been ineffective as treatment for problem behavior. Because most early research on FM DRO included presentation of a signal at the end of the DRO interval, it is unclear whether the limited effects of FM DRO were due to (a) the momentary response…

A functional analysis suggested that rumination exhibited by an adult with autism was maintained by automatic reinforcement. Next, a preference assessment with three flavor sprays (i.e., flavored sprays used by dieters) showed that apple pie spray was most preferred. Finally, the effects of fixed-time delivery of the apple pie spray on levels of…

Previous research suggests that motivating operation (MO) manipulations may assist in assessing discriminated manding (Gutierrez et al., 2007). The current study partially replicated and extended previous research by varying access to concurrently available reinforcers with different preference values (i.e., MO manipulations). Manding did not…

Self-injurious behavior (SIB) that occurs at high rates across all conditions of a functional analysis can suggest automatic or multiple functions. In the current study, we conducted a functional analysis for 1 individual with SIB. Results indicated that SIB was, at least in part, maintained by automatic reinforcement. Further analyses using…

The value of a reinforcer may change based on antecedent events, specifically the behavior of others (Bruzek & Thompson, 2007). In the current study, we examined the effects of manipulating the behavior of the therapist on problem behavior while all dimensions of reinforcement were held constant. Both participants' levels of problem behaviors…

Although delusional statements in people with intellectual disabilities and traumatic brain injury can be treated using behavioral interventions, none have demonstrated long-term treatment effects. In the current study, a functional analysis demonstrated that delusional statements were maintained by attention. Differential reinforcement of…

A functional analysis indicated that chronic eye poking exhibited by a woman with profound mental retardation persisted in the absence of social contingencies. We initiated a procedure in which a therapist delivered a punisher (mild reprimand) contingent on eye poking in the presence, but not the absence, of a neutral stimulus (wristbands).…

Functional analysis has been demonstrated to be an effective method to identify environmental variables that maintain problem behavior. However, there are cases when conducting functional analyses of severe problem behavior may be contraindicated. The current study applied functional analysis procedures to a class of behavior that preceded severe…

We compared results of descriptive and functional analyses of problem behavior for 12 participants whose descriptive data have been reported previously (Thompson & Iwata, 2001). Results indicated that in only 3 of the 12 cases was problem behavior maintained by the consequence observed most frequently during the descriptive analysis. Attention was…
