Escape-maintained

We evaluated the effects of two daily activity schedules on 2 participants' rates of aberrant behavior and their compliance. Functional analysis identified the operant function of the participants' aberrant behaviors to be escape from tasks. Participants were taught to use stimuli contained in daily schedules, and were tested based on a modified stimulus-equivalence model that consisted of flash cards and activity schedules comprised of words or photographs that corresponded to the participants' daily activities...

PURPOSE: To establish the conditional use of requests for assistance as an alternative to escape maintained challenging behaviour. METHOD: The study involved a 12-year-old boy with a behaviour disorder. Experiment 1 involved the implementation of a reversal design comparing the learner's performance during "easy" and "difficult" addition problems. Experiment 2 involved the implementation of a quasi-experimental design to establish the conditional use of requests for assistance...

The effect of presession attention on the later occurrence of problem behavior was examined with elementary-school children with a range of disabilities. Results of analogue functional analyses suggested an escape function, an attention function, or both. Following the analogue functional analyses, the effects of two antecedent conditions (10-min ignore vs. 10-min attention) were compared on problem behavior in subsequent test conditions. For participants who displayed attention-maintained problem behavior, the test condition involved contingent attention for problem behavior...

This study assessed whether the function of an individual's problem behavior was related to the effectiveness of an intervention involving choice among tasks. Analogue functional analyses were conducted with 7 students with various diagnoses to determine whether problem behaviors were maintained by escape or attention. Following identification of the function of each student's problem behavior, reversal designs were used to assess the effectiveness of an intervention that allowed the students to choose their own instructional tasks...

Positive reinforcement was more effective than negative reinforcement in promoting compliance and reducing escape-maintained problem behavior for a child with autism. Escape extinction was then added while the child was given a choice between positive or negative reinforcement for compliance and the reinforcement schedule was thinned. When the reinforcement requirement reached 10 consecutive tasks, the treatment effects became inconsistent and reinforcer selection shifted from a strong preference for positive reinforcement to an unstable selection pattern...

We examined the influence of background noise on levels of problem behavior and pain behavior under functional analysis conditions for a child with a diagnosis of Williams syndrome and hyperacusis. Background noise was associated with increases in escape-maintained problem behavior and increases in pain behavior such as clasping ears and crying. When the child was fitted with earplugs, there were substantial reductions in both problem and pain behavior under the background noise condition.

Escape-maintained aberrant behavior may be influenced by two outcomes: (a) a break from the activity and (b) subsequent access to preferred activities. To assess this hypothesis, a treatment was developed that analyzed response allocation across two break options: break alone and break with access to preferred social activities. The break with preferred activities decreased aberrant behavior and increased appropriate behavior.

We examined the relation between sleep deprivation and changes in level and allocation of aberrant behavior (aggression and self-injury) for a child with moderate mental retardation. First, a series of functional analyses identified that self-injury (SIB) and aggression were maintained by escape from demands (i.e., were members of the same response class). Escape from demand conditions were then held constant over time while natural levels of sleep deprivation occurred. This final analysis demonstrated a correlation between sleep deprivation and increases in escape-maintained aberrant behavior...

We evaluated a methodology for identifying the range of stimulus features of antecedent stimuli associated with aberrant behavior in demand contexts in natural settings. For each participant, an experimental analysis of antecedents (Phase 1) was conducted to confirm the hypothesis that task instructions occasioned increases in aberrant behavior. During Phase 2, specific stimulus features associated with the presentation of task instructions were assessed by evaluating the child's behavior across two distinct settings, therapists, and types of tasks in a sequential fashion...

We compared the effects of reinforcing compliance with either positive reinforcement (edible items) or negative reinforcement (a break) on 5 participants' escape-maintained problem behavior. Both procedures were assessed with or without extinction. Results showed that compliance was higher and problem behavior was lower for all participants when compliance produced an edible item rather than a break. Treatment gains were achieved without the use of extinction. Results are discussed regarding the use of positive reinforcement to treat escape behavior...

This article examined the relationship between the accuracy of academic responding and aggression for two boys with mild mental retardation. Their teacher reported low rates of correct responding and high rates of aggressive behavior during spelling instruction. A functional analysis showed that aggression was escape maintained. Following the functional analysis, participants were tested on relations between printed, photographic, and dictated stimuli corresponding to their spelling words. On pretests, they were unable to match printed words to their photographs or to their dictated names; they could neither name the printed words nor spell the photographs or dictated words...

We compared the effects of continuous reinforcement (play) and alone conditions as controls during functional analyses for 66 individuals whose self-injurious behavior (SIB) was maintained by escape. In every case, SIB was lower during both control conditions than it was during the test (demand) condition. However, SIB was lowest during the alone condition more often than it was during the play condition. Circumstances under which the alone condition might serve as an alternative or more suitable control for escape-maintained problem behaviors are discussed...

The escape-maintained destructive behavior of a girl with mental retardation persisted during hygiene routines with directive prompting, differential reinforcement for compliance, and extinction as treatment. Using nondirective prompting and noncontingent reinforcement, destructive behavior was reduced to near-zero levels during the hygiene routine.

We identified 3 clients whose destructive behavior was sensitive to negative reinforcement (break from tasks) and positive reinforcement (access to tangible items, attention, or both). In an instructional context, we then evaluated the effects of reinforcing compliance with one, two, or all of these consequences (a break, tangible items, attention) when destructive behavior produced a break and when it did not (escape extinction). For 2 clients, destructive behavior decreased and compliance increased when compliance produced access to tangible items, even though destructive behavior resulted in a break...

The escape-maintained destructive behavior of a boy with autism was reduced during instructional sequences with differential reinforcement of compliance (DRA), escape extinction without physical guidance, and demand fading. The procedure decreased destructive behaviors to near-zero levels and greatly increased compliance.

Functional analysis identified the consequences that maintained aggressive behavior and the relationship between these consequences and sleep deprivation for an individual with severe mental retardation. Results showed that aggression was maintained by negative reinforcement contingencies (escape from demand) and that aggression was more severe when sleep deprivation was present. A multicomponent intervention resulted in reductions of aggression for up to 7 months.

The effects of functional communication training, extinction, and response chaining on 3 subjects' escape-maintained aberrant behavior were evaluated using a multielement design. Functional communication training consisted of teaching subjects a verbal response that was functionally equivalent to their aberrant behavior. Subjects initially were allowed to escape from a task contingent on the trained verbal response. In subsequent treatment phases, escape was contingent on the trained verbal response plus the completion of the specified number of steps in the task (response chaining)...
